referring to fig1 through 12 c , wherein like reference numerals refer to like components in the various views , there is illustrated a new and improved intra - bronchial apparatus for aspiration or insufflation of lung regions distal to the apparatus placement or air passageway cross - communication . the air flow control valve portion apparatus is generally denominated 100 herein , while the deployment and placement system device is generally denominated 700 . fig1 - 8d illustrate a first preferred embodiment of the air flow control valve portion of the present invention . these views collectively show that the valve comprises a center tube 110 having a central lumen 120 , an outside surface 130 , an upper portion 140 , and a lower portion 150 . the valve further includes a plurality of resilient , arcuate strut arms 160 , each having an upper arcuate portion 170 with a tip 180 shaped for anchoring the valve on the interior lumen wall of a body cavity , duct , vessel , or passageway . the lower ends 190 of the strut arms are disposed in an evenly spaced arrangement around the lower portion 150 of the center tube 110 . a woven or polymeric air restriction membrane 200 is molded , adhesively bonded , woven , or fused to the strut arms and center tube to form a columnar or tubular portion 210 around the lower portion of the center tube and lower ends 190 of the strut arms . the membrane has a lower border 220 and an upper border 230 , the latter encircling the strut arms immediately under the lower end 175 of the upper arcuate portion of the strut arms . a collet or ferrule 240 is placed over the tubular portion 210 of the air restriction membrane / center tube / strut arm assembly . the collet may include one or more longitudinal slits 250 to facilitate a firm press - fit placement . optionally , the valve may include an inner membrane 260 disposed inside the central lumen of the center tube , which may be either a solid disc that permits no passage or leak of gases in or out , or it may be provided with slits or flaps or other valve elements that permit one - way or bi - directional passage of air , as is known in the art . the inner membrane cooperates with the patient &# 39 ; s natural mucous production to create a seal . the valve may be introduced into the air passageway with the inner membrane fully intact and impermeable and thereafter perforated by medical instrument for treatment of the lung region distal to the device . fig1 - 5 and 7 a - 9 show both the air flow control element of the present invention , as well as the distal portion of the catheter of the deployment and placement system 700 of the present invention . the deployment and placement catheter 710 includes a center lumen 720 extending the entire length of the catheter and a body portion 730 encasing and defining the center lumen 720 . disposed between the center lumen and the outside diameter 733 of the catheter are at least four control wire lumen 736 in which at least two steering wires 740 are slidingly disposed , and at least two release ring wires 750 are also slidingly disposed . at the distal end 760 of the catheter is a steering tip 770 operatively connected to steering wires 740 . the tip includes a center lumen 780 coaxial with the catheter &# 39 ; s center lumen . the steering tip includes two throughholes 790 so that the release ring wires 750 fasten at their ends to a release ring 800 . fig9 - 12c show the handle assembly and control elements of the deployment and placement device of the present invention . these views collectively show that the deployment and placement catheter 710 connects the air flow control element with a steering and release handle assembly 900 , which includes a housing 910 having upper and lower portions 920 , 930 , and a back plate 940 having a stem 950 . a steering knob 960 is disposed in the upper portion and is connected to a steering wire cam 970 , around which are fastened the proximal ends of the steering wires 740 . control inputs through the steering knob exert right or left pulling forces communicated the entire length of the steering wire and catheter to the steering tip disposed at the distal end of the catheter . a release ring lock handle 980 includes a throughhole 990 into which stem 950 is inserted , and along which the lock handle moves longitudinally . the handle extends upwardly through a slot 1000 in the upper portion 920 of the housing for forward and backward control inputs by the user . the handle is connected to top and bottom release ring wires , 750 a , 750 b , which extend the length of the deployment catheter 710 to the release ring 800 . deployment proceeds as follows : when connected to the air flow control valve assembly , the steering tip at the distal end of the deployment and placement system catheter is inserted into the center lumen 120 of the center tube 110 ; the strut arms 170 are bent , gathered , and bunched at their upper arcuate ends 170 around the upper portion 140 of the center tube to bring the membrane 200 of the valve into a collapsed configuration 20 ( fig1 , 7 a - b , 8 a ). the release ring is then disposed around the arcuate upper ends of the strut arms to retain and restrain them from moving outwardly , forced by their resilient characteristics and inherent shape memory . in this configuration , the assembly is adapted for insertion into a patient &# 39 ; s trachea and steered into a target air passageway . when the target location is reached , the release ring is pulled off the strut arm upper ends by the operator controlling the release ring wires , thereby allowing the strut arms to move outwardly and urge the membrane into an open configuration . increasingly , but partially open configurations 30 , 40 , are shown in fig2 and 3 , while a fully open configuration 50 , is shown in fig4 . when directed to an air passageway and deployed therein , the tips of the strut arms are urged outwardly to engage the interior walls of the air passageway and to provide both a frictional fit and partial penetration of vessel tissue to resist displacement . while so deployed , the central lumen of the valve member center tube provides means for delivering drugs to treat pulmonary conditions concurrently with lung reduction therapy . the method comprises the steps of : ( 1 ) providing the above - describe intra - bronchial air flow restriction apparatus with the valve member with a central lumen ; ( 2 ) deploying the intra - bronchial air flow restriction apparatus in an air passageway in fluid communication with a lung region to be collapsed and pharmaceutically treated ; ( 3 ) anchoring the intra - bronchial air flow restriction apparatus in the air passageway wall ; and ( 4 ) delivering therapeutic drugs to lung regions distal to the valve member through the central lumen of the valve member . it will be appreciated by those with skill in the art that the present invention is unique in providing a restriction air valve with an accessible central lumen in substantially the center of the valve that allows selective delivery of drugs or other therapeutic actions in lung regions distal to the valve element . the foregoing disclosure is sufficient to enable one having skill in the art to practice the invention without undue experimentation , and provides the best mode of practicing the invention presently contemplated by the inventor . while there is provided herein a full and complete disclosure of the preferred embodiments of this invention , it is not intended to limit the invention to the exact construction , dimensional relationships , and operation shown and described . various modifications , alternative constructions , changes and equivalents will readily occur to those skilled in the art and may be employed , as suitable , without departing from the true spirit and scope of the invention . such changes might involve alternative materials , components , structural arrangements , sizes , shapes , forms , functions , operational features or the like . accordingly , the proper scope of the present invention should be determined only by the broadest interpretation of the appended claims so as to encompass all such modifications as well as all relationships equivalent to those illustrated in the drawings and described in the specification .
