Abstract: A balloon for medical treatments such as percutaneous transluminal coronary angioplasty (PTCA), delivery of a vascular stents or stent grafts, employs reinforcement materials that are patterned so as to promote consistent folding of the balloon. The reinforcements may be fiber fabric reinforcements and the balloon may be used for biocidal treatment.

Abstract: A medical device includes yarns made of a shape memory material and polymer yarns, wherein the yarns made of said shape memory material include polymer sheathing.

Abstract: A woven textile vascular prosthesis including a tubular trunk and at least one fork, each fork having an apex located between outgoing tubular branches with a small diameter, wherein at least a portion of a wall of the prosthesis in a zone of the apex is woven more densely than in other zones having an original weave construction.

Abstract: A woven prosthesis, such as a woven vascular graft, woven from warp and weft yarns. Velour warp yarns forming the prosthesis are selectively incorporated into a base layer of the prosthesis so as to provide a bulbous section without compromising the porosity of the prosthesis.

Abstract: A surgical implant is made from biocompatible fiber material as a woven textile fabric, in particular in the form of a vascular prosthesis, the woven fabric being so configured that its permeability to blood is so low that the blood impregnates the textile fabric upon implantation and seals it off by coagulating, but does not flow through it.

Abstract: Sheathing for reinforcing natural veins for use as surgical implants in the form of textile netting that is configured by forming a seamless, tubular, essentially pile-less, knit fabric and has loops having large, open apertures having essentially polygonal shapes is made available.

Abstract: Polymeric fibers were microbraided around a mandrel to make a tubular guide tube for nerve regeneration. The polymer used for the fibers was one of poly(L-lactide-co-glycolide) (10:90 PLGA) and chitosan. These polymers are biodegradable and biocompatible. The tubes were studied for their surface morphology and swelling behavior. Biological performance of the tubes was examined in the rat sciatic nerve model with a 12 mm gap. One month after implantation nine out of ten rats showed successful nerve regeneration. Morphometric analysis of regenerated nerves confirmed the quality of the regeneration compatible with those offered by other types of biodegradable nerve guide tubes. The tubes were flexible, permeable and showed no swelling.

Abstract: A graft (1) having a band of fibrous material (13) on an outer surface thereof adjacent its proximal end (9). The band of fibrous material extends circumferentially around the graft to promote adhesion. The band can be continuous around the proximal end of the graft. The band can be formed from a patch of fibrous material, cut or loop pile velour, by fibres woven or knitted into the material of the graft or by brushing of material of the graft to raise fibres of the material of the graft. The band of fibrous material has a length of from 5 mm to 15 mm along the length of the graft.

Abstract: A method and apparatus relating to a biocompatible soft tissue implant is disclosed. The implant, in the form of a prosthesis, is constructed of a knitted pile mesh material arranged into either a 3-dimensional structure or a planar shape or structure. The material or fabric includes a plurality of filament extensions projecting outwardly therefrom. The filament extensions can be radially projecting looping filaments from one or more rows of the knitted pile mesh material. The combination of the filament extensions with the 3-dimensional structure results in the biocompatible implant having a structural resistance to hinder anticipated crushing forces applied to the implant, and also provide a suitable 3-dimensional structure for promoting rapid tissue in-growth to anchor such implant without migration and strengthen the repaired tissue area.

Abstract: Provided is a biocompatible device which has been coated or sealed with a polyether or polyether/carbonate based urethane polymer that contains functional groups (e.g. carboxylic acid groups) which are capable of serving as anchor sites for protein binding.

Abstract: A woven vascular graft having a texturized outer surface to promote tissue ingrowth into the graft. The outer surface of the graft is equipped with a plurality of threads that are woven into, and extend from, the outer surface. The threads may be arranged in rows, lines or a geometric pattern. Alternatively, the threads may be towel-like. Such towel-like threads may be arranged in the form of a cuff at each end of the graft, or may cover larger portions of the exterior of the graft. The graft may be equipped with only one texture, or with a plurality of different textures.

Abstract: The present invention provides a soft-tissue prosthesis which is formed from a tubular textile substrate and a liner. The liner is affixed to the intraluminal surface of the tubular textile portion of the soft-tissue prosthesis to form a fluid-tight barrier on the intraluminal surface of the prosthesis. The liner is preferably formed from a polymer. Thus, the soft-tissue prosthesis formed in accordance with the present invention provides the advantages of both a textile prosthesis and a polymer prosthesis.

Abstract: A fabric graft having a high external velour profile is provided. The textile graft may be woven or knitted to form a tubular prosthesis. The high external velour profile is provided by outwardly extending loops ranging from about 1 mm to about 5 mm in length. The fabric graft is self-sealing to minimize bleeding after puncture by a dialysis needle.
