specific embodiments of the invention will now be described with reference to the accompanying drawings . this invention may , however , be embodied in many different forms and should not be construed as limited to the embodiments set forth herein ; rather , these embodiments are provided so that this disclosure will be thorough and complete , and will fully convey the scope of the invention to those skilled in the art . the terminology used in the detailed description of the embodiments illustrated in the accompanying drawings is not intended to be limiting of the invention . in the drawings , like numbers refer to like elements . unless otherwise defined , all terms ( including technical and scientific terms ) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs . it will be further understood that terms , such as those defined in commonly used dictionaries , should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein . the implant according to the present invention may , for example , be employed to provide suburethral support and thereby prevent or minimize the leakage of urine or incontinence . in this respect , the implant is operative to act as a suburethral sling , as is known in the art , but is advantageously operative to be more easily secured into position than prior art sling implants . the implant of the present invention is further capable of being deployed in a manner that is far less traumatic than prior art sling implants and methods of surgically implanting the same , and further utilizes a novel attachment approach that provides for optimal suburethral positioning of the implant . as shown in fig1 - 3 , according to certain embodiments of the present invention , an implant 10 employs a support member 20 through which two or more anchors 30 are inserted . the anchors 30 are employed to pierce a target tissue , such as obturator internus muscle , obturator internus fascia , obturator membrane , arcus tendineus levator ani , and levator ani muscle , thereby suspend the support member across an internal regions of the body . extending from the anchors 30 are anchor sutures 40 that facilitate locating the relevant anchor 30 and reengagement of a delivery system with the anchors 30 . as shown in fig3 , extending from the support member 20 is one or more support member suture 50 . the support member suture 50 thereby provides a marker indicating an approximate position of the mid - point of the support member 20 during and after implantation . with respect to the support member 20 , the support member 20 is a piece of material having a generally rectangular or oblong shape . the support member 20 may be fabricated of a synthetic material , such as surgical mesh and the like , natural tissues , such as tissues harvested from either an animal , cadaverous source or the patient himself , and / or combinations of synthetic and natural materials . in a preferred embodiment , the support member 20 is fabricated of a mesh or weave . the support member 20 may , for example , be 5 - 30 mm wide by 30 - 150 mm long , and preferably 8 - 15 mm wide by 50 - 90 mm long . as seen in fig3 and 17 , in certain embodiments , the support member suture 50 is advantageously attached to the support member 20 . the support member suture 50 is looped through , tied to , or otherwise associated with the support member 20 . preferably , the support member suture 50 is affixed to the support member 20 at a proximate mid - point of the support member 20 . as would be understood by one of ordinary skill in the art , it may also be advantageous to employ a plurality of the support member sutures 50 at predetermined positions on or within the support member 20 in order to provide a plurality of markers along a length of the support member . in order to distinguish the various individual sutures , the support member sutures , as well as the anchor sutures , may be provided in different colors , lengths , or other indicating means that would allow a user to distinguish one suture from another . turning next to fig4 - 8 , fig4 - 8 show various embodiments of the anchor 30 of the present invention . the anchor 30 has a distal portion 60 and a proximal portion 70 associated with one another by mid - portion 80 . a proximal end of the distal portion 60 of the anchor 30 is associated with or attached to a distal end of the mid - portion 80 . conversely , a distal end of the proximal portion 70 is associated with or attached to a proximal end of the mid - portion 80 of the anchor 30 . the mid - portion 80 of anchor 30 is formed as a shaft or spacer that serves to provide space between the distal portion 60 and the proximal portion 70 to , for example , accommodate a depth of tissue through which the distal portion 60 has penetrated . the distal portion 60 of the anchor 30 employs a piercing tip 62 for penetrating tissue and a tissue - retention protrusion 64 proximal of the piercing tip 60 that anchors or secures the distal portion 30 within tissue . the distal portion 60 may have , for example , an arrowhead - like shape as shown in fig5 - 7 . alternatively , distal portion 60 may have a more complex shape configured to employ more than two , for example as shown in fig8 , four tissue - retention protrusions 64 . the distal portion 60 may further employ a conical or cone - like shape having a circular tissue - retention protrusion 64 . one of ordinary skill in the art would recognize that alternative shapes and configuration of the distal portion 60 are possible while still achieving the desired objective . for example , distal portion 60 may employ resilient , spring loaded and / or self - tensioning tissue - retention protrusions 64 . the proximal portion 70 of anchor 30 comprises a shoulder 72 for providing a back - stop for the support member 20 and a guide member 74 for engagement with a delivery system , as discussed in greater detail below . the proximal portion 70 may , optionally , further employ recesses 76 and eyelet 78 . the anchor suture 40 passes through the eyelet 78 and is , for example , secured back to itself to form a loop . the recesses 76 may be positioned on one or both side of the eyelet 78 and configured so as to accept the anchor suture 40 such that the presence of the anchor suture 40 does not add to or change an outer dimension of the guide member 74 . the anchor 30 may be formed from a variety of materials , including but not limited to metal alloys , such as titanium , stainless steel , or cobalt - chome alloys , polymeric materials , such as polyethylene ( pe ), polypropylene ( pp ), polysulfone , polyether ether ketone ( peek ), polyether imide ( pei ), and biodegradable materials , such as polylactic acid ( pla ) and polyglycolic acid ( pga ) based materials . the anchor 30 may be formed of a single material or a combination thereof . for example , as illustrated in fig9 a and 9b , the anchor 30 may be formed of a combination of primary material 90 , such as titanium , and a biodegradable material 92 assembled or molded over the primary material 90 . turning next to fig1 a - 10f , fig1 a - 10f show the steps of assembling the implant 10 according to various embodiments of the present invention . for the sake of clarity , fig1 a - 10f show only the assembly of one side of the implant 10 . first , a tool 90 is used to form an opening 110 through the support member 20 proximate an end of the support member 20 by penetrating , stretching , or spreading the mesh or knitted material of the support member 20 . the tool 90 has a tapered or pointed end and a cross - section shape in the form of a circle , rectangle , oval or most any other shape . the distal portions 60 of the anchors 30 are then inserted through the openings 110 in the support member 20 until the support member 20 rests against the shoulders 72 of the proximal portions 72 of the anchors 30 . in a preferred embodiment , the openings 110 are formed interior of the outer perimeter of the support member 20 such that there is sufficient material of supporting member 20 so that the openings 110 do not substantially expand or rip though the outer perimeter of the support member 20 . with the anchors 20 inserted through the support member 20 , the implant 10 may then be implanted into the patient . in an alternative embodiment of the present invention , as shown in fig1 a - 11d , the shoulder of the anchor 31 is formed of a plastic or metal pin 73 that is inserted through a receiving hole 75 formed through the proximal portion of the anchor 31 . during assembly of the implant 10 , once the openings 110 are formed through the support member 20 , the guide 74 and / or proximal portion 70 of anchor 31 is placed through the opening 110 and the pin 73 is inserted through the receiving hole 75 to form a element functionally similar to the shoulder 72 previously described . as one of ordinary skill in the art would recognize , this embodiment provides the advantage that a smaller opening 110 may be formed when assembling the implant 10 . the smaller opening 110 , in turn , provides the advantage of the support member 20 having a greater resistance to tearing and deformation . in certain other embodiments of the present invention , the assembled implant 10 as described above may be subjected to additional fabrication steps . for instance , as shown in fig1 - 3 , and 12 - 14 , after insertion of the anchor 30 through the opening 110 of support member 20 , a portion of the support member 20 between the opening 10 and the outer perimeter of the support member 20 is folded over the shoulder of the anchor 30 back on to itself to form a folded portion 22 . the folded portion 22 may then be bonded , sutured , welded , or tacked to it self to form bond 24 to better maintain the fold . formation of the folded portion 22 serves , in part , to decrease resistance to penetration of the anchor 30 into tissue . the fold 22 may additionally help insure that the anchor 30 remains inserted through the support member 20 during handling and implantation of the implant 10 , as well as provide a more visually appealing appearance to the implant 10 . as shown in fig1 a - 12d and 13 , the shape of the portion of the support member 20 that forms the fold 22 may be manipulated so as to , for example , result in an implant 10 that has a tapered end . a tapered end may be formed by forming a portion of the support member 20 so as to have a width that narrows at a fold line 26 , as shown in fig1 a . a tapered end may also be formed through a secondary folding of the extremities or corners of the fold 22 towards one another , as shown in fig1 b . alternatively , as shown in fig1 c , once the folded portion 22 is formed a suture may be threaded through the fold 22 and cinched and bound to itself so as to form a tapered end of the anchor 30 . a tapered end may also be formed in the implant 10 by cutting or trimming the corners of the fold 22 after the fold 22 has been formed , as shown in fig1 d . fig1 a - c show yet another embodiment of the implant 10 in which , prior to formation of the fold 22 , the support member 20 is twisted 180 degrees or more . again , this method of assembly decreases resistance to penetration of the anchor and helps ensure that the anchor 30 remains inserted through the support member 20 during handling and implantation . one of ordinary skill in the art will , however , recognize that other methods of assembling the support member 20 and the anchor 30 to achieve the desired characteristics of the implant 10 are known in the art . turning now to the delivery system of the present invention . broadly speaking , the delivery system is configured to receive a portion of the anchor 30 of the assembled implant 10 . fig1 shows a delivery system 120 having a handle 130 and a shaft 140 . the handle 130 is preferably ergonomically shaped to facilitate grasping and manipulating . the handle 130 is preferably marked , colored , textured or otherwise configured so as to indicate to a user the orientation of the delivery system 120 . the shaft 140 protrudes from or is an extension of the handle 120 . the shaft 130 is , for example , formed of stainless steel or other metal in the general shape of a needle . a curved distal portion 142 of the shaft 140 includes a cavity 144 and a slot 146 . referring now to fig1 and 16 , fig1 shows the implant 10 and delivery system 120 assembled ready for implantation of the implant 10 . fig1 shows a cross - sectional view of the assembled implant 10 and delivery system 120 viewed along section line a - a of fig1 . as will be noted , the shape of the cavity 144 corresponds to the shape of the guide 74 of the anchor 30 . that is to say that the guide 74 of the anchor 30 of the implant 10 and the cavity 144 of the shaft 140 of the delivery system 120 are complementary elements , the cavity 144 forms a female receiving element for the male guide 74 . preferably , the cavity 144 and the guide 74 are formed in the shape of a square , rectangle , oval , triangle , star , or other shape that resists the guide 74 rotating within the cavity 144 . in certain embodiments of the present invention , the cavity 144 and the guide 74 form a friction fit such that the guide 74 is maintained within the cavity 144 during handling and deployment of the implant 10 but is readily released from the cavity 144 upon engagement of the distal portion 60 of the anchor 30 with tissue . a portion of the slot 146 penetrates radially through the shaft 140 into the cavity 174 and extends axially along a length of the distal portion 142 of the shaft 140 . preferably , the slot 146 extends axially along the shaft 140 to a greater extent than the cavity 174 . the slot 146 thereby receives and forms a channel through which the anchor suture 40 of anchor 30 is positioned along an axis of the shaft 140 . a method for deploying or implanting the implant 10 according to certain embodiments of the present invention will now be described . first , a single incision or entry point is made in the patient followed by blunt dissection as necessary or desired . for example , the entry point may be made in the anterior wall of the vagina . one side of the implant 10 that is engaged with the delivery system 120 , as previously described , is then inserted through the entry point and the anchor 30 that is engaged with the delivery system 120 is forced into or through a portion of the target tissue . the delivery system 120 is retracted away from the anchor 30 that has penetrated the target tissue thereby breaking the engagement between the delivery system 120 and the anchor 30 . during this process and particularly while the delivery system 120 is being retracted , the user secures the corresponding anchor suture 40 such that the delivery system 120 is retracted while an end of the anchor suture 40 is maintained extending out from the entry point . a second side of the implant 10 that is engaged with the delivery system 120 is then implanted as described with regard to the first side . substantially concurrent with the implantation of the second side of the implant 10 , the support member 20 of the implant 10 is positioned so as to support the desired organ , for example a portion of the urethra . the support member suture 50 , shown in fig3 and 17 , may be used to determine the position and / or tension of the implanted support member 20 . the tension of the support member 20 of the implant 10 is initially adjusted by pushing the delivery system 20 such that the second side of the implant 10 is forced further into the target tissue . the delivery system 120 is then retracted from the second side of the implant 10 . an end of the second anchor suture 30 is also maintained such that it extends out from the entry point . should it be determined that greater tension is desired or if it is otherwise desirable to reengage of the delivery system 120 with one of the anchors 30 , the present invention provides a particularly advantageous means for achieving such . as shown in fig1 , the end of the anchor suture 40 of the relevant anchor 30 that extends from the entry point is tensioned and secured . the slot 146 of the delivery system 120 is then positioned such that the anchor suture 40 passes through the slot 146 , and serves as a guide for the delivery system 120 to the relevant anchor 30 . the delivery system 120 is advanced towards the relevant anchor 30 along the anchor suture 40 . the guide 74 of the anchor 30 is thereby received by the cavity 144 of the delivery system 120 and , if desired , the friction fit between the anchor 30 and the delivery system 120 is reestablished . it is then possible to adjust the tension of the support member 20 of the implant 10 by pushing the delivery system 120 so as to drive the anchor further into the target tissue . the implant 10 can be retracted by pulling on the anchor suture 40 thereby releasing all or a portion of the tension present in the implant 10 . upon completion of the implantation of the implant 10 , the anchor sutures 40 and support member sutures 50 can be left in place for possible use in a follow - up procedure or may be removed from the patient . while the present invention has been described for use in slings for treating incontinence , it would be understood by one of skill in the art that the present invention , either in part in its entirety , can also be used for treating pelvic floor disorders , for supporting a broad range of organs within the body , and for fixing tissue or implants within the body . although the invention has been described in terms of particular embodiments and applications , one of ordinary skill in the art , in light of this teaching , can generate additional embodiments and modifications without departing from the spirit of or exceeding the scope of the claimed invention . accordingly , it is to be understood that the drawings and descriptions herein are proffered by way of example to facilitate comprehension of the invention and should not be construed to limit the scope thereof .
