for the following defined terms , these definitions shall be applied , unless a different definition is given in the claims or elsewhere in this specification . all numeric values are herein assumed to be modified by the term “ about ”, whether or not explicitly indicated . the term “ about ” generally refers to a range of numbers that one of skill in the art would consider equivalent to the recited value ( i . e ., having the same function or result ). in many instances , the terms “ about ” may include numbers that are rounded to the nearest significant figure . the recitation of numerical ranges by endpoints includes all numbers within that range ( e . g ., 1 to 5 includes 1 , 1 . 5 , 2 , 2 . 75 , 3 , 3 . 80 , 4 , and 5 ). as used in this specification and the appended claims , the singular forms “ a ”, “ an ”, and “ the ” include plural referents unless the content clearly dictates otherwise . as used in this specification and the appended claims , the term “ or ” is generally employed in its sense including “ and / or ” unless the content clearly dictates otherwise . the following description should be read with reference to the drawings wherein like reference numerals indicate like elements throughout the several views . the drawings , which are not necessarily to scale , depict illustrative embodiments of the claimed invention . a balloon catheter 10 having a hub and strain relief assembly 12 having two luer - type valves , an elongate catheter shaft 14 and an inflatable balloon 16 is disposed on a distal protection guidewire 18 having a distal protection device 20 disposed on a wire 22 , as shown in fig1 . there are many means for connecting a balloon to a catheter shaft and the means illustrated are not meant to be limiting , but merely illustrative . the balloon includes a proximal waist 24 , a proximal cone 26 , a central section 28 and a distal cone 30 . it also includes a distal waist 32 ( not pictured ). these sections of the balloon are part of one continuous balloon and are distinguished only to illustrate the features of the balloon . as is the case in many conventional balloon catheters , the proximal waist 24 extends proximally from the proximal cone 26 and is bonded to catheter shaft 14 . unlike the proximal waist and as will be illustrated in more detail below , distal waist 32 is everted and extends proximally from distal cone 30 and is bonded to catheter shaft 14 . as can be seen , this arrangement shortens the balloon 16 distal of the central section 28 to create a shortened landing zone , which permits the central section of the balloon to be positioned closer to the distal protection device 20 . balloon catheter 10 may be an angioplasty catheter , a stent delivery catheter , a cutting balloon catheter , or other types of balloon catheters . the hub and strain relief assembly 12 shown is merely illustrative . balloon catheter 10 may include any suitable hub or hub and strain relief or have any suitable proximal terminal assembly . the catheter shaft 14 includes an inflation lumen fluidly connected to the balloon 16 and a guidewire lumen in which distal protection guidewire 18 is disposed . the catheter shaft may have other lumens if desired . for example , it may have a lumen for the delivery of therapeutic agents or a second inflation lumen for a second balloon . the catheter shaft is depicted as a coaxial configuration ; other configurations are possible . the various tubular members that make up catheter shaft 14 are fixed with respect to each other . for example , they may be fixed towards the distal end to increase columnar support . further , the catheter shaft and hub may be any suitable configuration . for example , in some embodiments a single - operator - exchange configuration , where the guidewire lumen extends along only a distal portion of the catheter shaft , is desirable . the balloon catheter is depicted as disposed on a distal protection guidewire , but it is not so limited . the balloon catheter may be disposed on any suitable device . for example , it may be disposed on a guidewire , an atherectomy device , a balloon catheter , a distal protection guidewire having a different distal protection device or other suitable apparatus . turning now to fig2 , which is a diagrammatic cross - sectional view of a distal portion of balloon catheter 10 , distal waist 32 is illustrated . catheter shaft 14 has outer tubular member 34 and inner tubular member 36 . an example radiopaque marking , radiopaque marker band 38 , which is shown disposed on inner tubular member 36 , may be disposed in a different location or on a different component . catheter shaft 14 is shown in a coaxial configuration , though other configurations are possible . for example , configurations with an off - center inner tubular member or having side - by - side tubular members are contemplated . central balloon section 28 is selected to have a desired size and proximal cone 26 tapers proximally therefrom to proximal waist 24 . distal waist tapers distally from the distal end of the central section to a distal waist 32 . as illustrated , distal waist 32 extends proximally from the distal cone . the balloon may be formed in this configuration or the balloon may be formed with distal waist 32 extending distally from the distal cone and then the distal waist is everted to the configuration shown . the distal waist may be bonded to inner tubular member 36 at the distal end thereof or may be bonded at a location proximal to the distal end . fig2 a is a diagrammatic cross - sectional view of a catheter 10 having a tapering distal tip 39 , which nevertheless retains a shortened landing zone over embodiments that have a distal waist extending distally from the distal cone . fig3 is a diagrammatic cross - sectional view illustrating the distal portion of a balloon catheter 40 . balloon 16 is disposed on a catheter shaft 14 . catheter shaft 14 has an inner tubular member 36 defining a guidewire lumen and an outer tubular member 34 which together with the inner tubular member defines the inflation lumen . while catheter shaft 14 is depicted as extending slightly beyond the distal waist , the catheter shaft 14 could terminate distally at the distal waist , further shortening the distal landing zone . balloon 16 includes proximal waist 24 , proximal cone 26 , central section 28 , distal cone 30 and distal waist 32 . proximal waist 24 extends proximally from central section 28 . distal cone 30 has a first portion 42 tapering from the central section distally and second portion 44 tapering from the first portion proximally . the distal waist 32 extends distally from the distal cone 30 . as is illustrated in the figure , this distal cone configuration shortens the length of the distal cone , shortening the length of the distal landing zone . of course , variations are possible . for example in one embodiment , distal cone 32 is everted and consequently extends proximally from the distal cone . likewise , the proportions of the first portion and the second portion may be varied with respect to each other . fig4 is a diagrammatic cross - sectional view illustrating the distal portion of a balloon catheter 46 , which is similar to balloon catheter 40 except for the variations discussed below . the distal cone 30 of the balloon tapers proximally from the distal end of balloon central section 28 to distal waist 32 , which extends distally from the distal cone 30 . balloon 16 is mounted on a catheter shaft 48 that has an outer tubular member and an off - center inner tubular member 50 . in some configurations , catheter shaft 48 can terminate at the distal end of distal waist 32 , further shortening the landing zone . fig5 is a diagrammatic cross - sectional view illustrating the distal portion of a balloon catheter 52 . balloon 16 , mounted on catheter shaft 14 , includes proximal waist 24 bonded to catheter shaft 14 , proximal cone 26 , central section 28 , distal cone 30 and distal waist 32 bonded to catheter shaft 14 . proximal and distal cones 26 and 30 extend proximally and distally , respectively , from balloon central section 26 . proximal waist 24 extends distally from proximal cone 26 and distal waist 32 extends proximally from distal waist 30 . this creates a more symmetric configuration that has a shortened distal landing zone . fig6 is a diagrammatic cross - sectional view illustrating the distal portion of a balloon catheter 54 . balloon 16 , mounted on catheter shaft 14 , includes proximal waist 24 bonded to catheter shaft 14 , proximal cone 26 , central section 28 , distal cone 30 and distal waist 32 bonded to catheter shaft 14 . distal cone 30 includes a first portion 42 tapering distally from balloon center section 26 and a section portion 44 tapering proximally from first portion 42 to distal waist 32 . proximal cone 30 includes a first portion 56 tapering proximally from balloon center section 16 and a section portion 58 tapering distally from first portion 56 to proximal waist 24 . proximal waist 24 extends proximally from proximal cone 26 and distal waist 32 extends distally from distal waist 30 . in other contemplated embodiments , proximal waist 24 may extend distally from proximal cone 26 and distal waist 30 may extend proximally from distal cone 30 . fig7 is a diagrammatic cross - sectional view illustrating the distal portion of a balloon catheter 60 , in which a balloon 16 is mounted on a catheter shaft 14 . the balloon has a central section 28 from which both proximal and distal cones 26 and 30 taper in a proximal direction . proximal waist 24 extends proximally from proximal cone 26 and distal waist 32 extends proximally from distal cone 30 . the distal end of catheter shaft 14 may terminate at the distal end of the distal waist , where the distal waist joins the distal cone to further shorten the landing zone . such a balloon catheter may be made according to the following method . an inflatable balloon having a distally extending distal cone and waist may be molded in a conventional manner . this balloon is then molded in a secondary process in which the distal cone and waist are everted and placed in a mold having a reverse - cone shape . the balloon is then low - pressure inflated over a mandrel and exposed to a temperature sufficient to cause a permanent set to keep the cone reverse after molding . alternatively , the distal cone and waist can be everted and bonded to the catheter shaft with no heat set . the balloon may be slid proximally onto the distal end of the catheter shaft proximally past the distal waist bonding location . an adhesive or epoxy may be applied to the catheter shaft and the balloon may be slid back into position to bond the distal waist in place . in another variation a section of heat shrink tubing is placed over the everted distal waist . when heat is applied , the tubing applies pressure to the distal waist . the proximal waist may be bonded using conventional means . in another method , the balloon is placed on the catheter and the proximal waist is bonded using conventional means . a tool is used to hold the everted distal cone in place and the balloon is low pressure inflated . a mandrel is slid into the guidewire lumen to apply heat at the location of the distal waist to create a thermal bond between the catheter shaft and the distal waist . the catheter in any of the embodiments may be made from any suitable materials and using any suitable construction . for example , the catheter may include a metallic hypotube section made from stainless steel or a nickel - titanium alloy . it may include a polymeric layer and may have a reinforcing layer such as a braid embedded therein . it may have section of varying rigidity and may have inner or outer liners having a low coefficient of friction such as a polytetrafluoroethylene ( ptfe ) liner . the polymer may be selected based on desired criteria such as strength and flexibility . suitable polymers may include thermoplastics , polyesters , polyurethanes , elastomeric polyamides , and silicones . the balloon material in any of the embodiments varies depending on the compliance of the balloon material desired . in general , the balloon material desired for the embodiments is either a polyether block amide ( pebax ), or polyethylene . when a compliant balloon material is desired , low pressure , relatively soft or flexible polymeric materials such as thermoplastic polymers , thermoplastic elastomers , polyethylene ( high density , low density , intermediate density , linear low density ), various co - polymers and blends of polyethylene , ionomers , polyesters , polyurethanes , polycarbonates , polyamides , poly - vinyl chloride , acrylonitrile - butadiene - styrene copolymers , polyether - polyester copolymers , and polyetherpolyamide copolymers are preferred . when a non - compliant balloon material is desired , materials having relatively rigid properties such as poly ( ethylene terphthalate ), polyimide , thermoplastic polyimide , polyamides , polyesters , polycarbonates , polyphenylene sulfides , polypropylene and rigid polyurethanes are desired . it should be understood that this disclosure is , in many respects , only illustrative . changes may be made in details , particularly in matters of shape , size , and arrangement of steps without exceeding the scope of the invention . the invention &# 39 ; s scope is , of course , defined in the language in which the appended claims are expressed .
