摘要： A thin-wall PTFE (polytetrafluoroethylene) tube in the form of a tube of porous expanded PTFE film wherein the porous PTFE film has a microstructure containing a multiplicity of fibrils oriented substantially parallel to each other. The tube has a wall thickness of less than about 0.25 mm and is made from at least one first layer and at least one second layer of porous PTFE film, wherein the fibrils of the first and second layers are oriented substantially perpendicular to each other. Preferably the fibrils of the at least one first layer are oriented substantially parallel to the longitudinal axis of the tube and the fibrils of the at least one second layer of porous PTFE film are oriented substantially circumferential to the tube. The first and second layers may be inner and outer layers respectively, or alternatively their relationship may be reversed. Alternatively, either of the first and second film layers may be replaced with alternative reinforcing components such as a braid or at least one reinforcing rib. The reinforcing rib is preferably in the form of a helically-wrapped metal wire located between the first and second layers.

摘要： A vascular graft in the form of a tube or flat sheet of biocompatible material having an outer covering of deflectably secured material such as porous film, fibers, discrete pieces of material, or combinations thereof. The vascular graft may be of tubular form for replacing or bypassing entire segments of veins or arteries or alternatively may be in the form of a flat sheet useful for repairing portions of the circumference of veins or arteries. The tube or flat sheet of biocompatible material and the outer covering of deflectably secured material are preferably of porous polytetrafluoroethylene. The vascular graft is useful for dialysis access in that it offers a reduction in blood leakage when the vascular graft is punctured by a dialysis needle and the needle is subsequently removed. It is also useful for reducing suture hole bleeding resulting from holes created through the graft by penetration of the graft with a suture needle.

摘要： An improved musical instrument string is provided. The string includes a polymer cover that protects the string, from contamination while maintaining the original "lively" sound of the musical string. By supplying the cover over a conventional string and preferable over a conventional wound string, the string is protected against contamination while also making the string easier to play. The preferred cover comprises at least one layer of expanded polytetrafluoroethylene (ePTFE) that is most preferably sealed with a polymer coating.

By supplying the cover over a conventional string and preferable over a conventional wound string, the string is protected against contamination while also making the string easier to play. The preferred cover comprises at least one layer of expanded polytetrafluoroethylene (ePTFE) that is most preferably sealed with a polymer coating. In particularly preferred embodiments, a cover is applied over a portion of the length of the string having a relatively reduced variable mass. The result is that the string has relatively uniform mass along its entire length thereby assuring correct intonation.

摘要： A fully flexible annuloplasty ring is temporarily stiffened during implantation by inserting a withdrawable stiffening wire into a lumen of the ring. The annuloplasty ring has a lumen which is able to hold the stiffener prior to and during insertion. The stiffener includes a portion extending out of the lumen which can be pulled to withdraw the stiffener once the implant has been implanted.

摘要： A vascular graft in the form of a tube or flat sheet of biocompatible material having an outer covering of deflectably secured material such as porous film, fibers, discrete pieces of material, or combinations thereof. Two different types of fibers may also be used.

The tube or flat sheet of biocompatible material and the outer covering of deflectably secured material are preferably of porous polytetrafluoroethylene. The inventive vascular graft is useful for dialysis access in that it offers a reduction in blood leakage when the vascular graft is punctured by a dialysis needle and the needle is subsequently removed.

摘要： An implantable lead in the form of an electrical conductor wire having an insulating layer of impervious plastic surrounding the surface of the electrical conductor wire and further having an exterior surface covering of porous PTFE. The impervious plastic insulating layer is preferably a thermoplastic and most preferably a thermoplastic fluoropolymer such as ETFE, FEP or PFA. The exterior surface covering of porous PTFE offers improved flexibility and biocompatibility in comparison to conventional lead wires having silicone exterior surfaces, while the impervious plastic insulating layer prevents loss of insulating integrity resulting from wetting out of the porous PTFE exterior surface by body fluids. Methods of making the implantable lead are also described.
