Continuously flat-woven implantable tubular prostheses have seamless woven sections which gradually change the number of warp yarns to smoothly transition, i.e., taper, from one diameter to another. Multi-diameter endoluminal grafts having a variety of shapes and configurations are made using a seamless weaving process without unacceptable voids or gaps in the tubular wall.

Shaped woven tubular soft-tissue prostheses and method of manufacturing the same

A thinly woven textile prosthetic implant such as a vascular graft may be implanted by catheter implantation. The implant includes an elongate tubular body formed of a woven fabric having a fabric thickness no greater than about 0.16 mm. The tubular body includes a series of longitudinally spaced wave-like generally uniform crimps along the length thereof. The crimps are disposed at a fine pitch along the length of the tubular body. The amplitude of the crimps is relatively small thus reducing the formation of thrombus and plaque on the inside of the implant.

An implantable textile prosthesis includes a first woven section having a tubular branch wall defining a fluid passageway therethrough. The tubular branch wall includes an elongate tubular extent and an asymptotically flared tubular extent, which is asymptotic with respect to the tubular branch wall. The asymptotically flared tubular extent includes a weaving pattern having a plurality of warp yarns and fill yarns and incorporating a gradual change in the number of warp yarns with respect to the fill yarns to provide a seamless and substantially fluid-tight transition region along said flared tubular extent. The tubular branch wall may be sutured to an elongate tubular main wall to provide an implantable tubular textile prosthesis particularly useful in branched end-to-side anastomoses. The tubular main wall may be heat-settably arched to resemble the natural arch of the aorta.

Aortic arch prosthetic graft

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.

Implantable tubular prosthesis

An implantable tubular textile prosthesis particularly useful in branched end-to-side anastomoses is provided. The prosthesis includes a first portion including an elongate tubular main wall which defines a fluid passageway therethrough, and a second portion including a tubular branch wall which extends laterally from the tubular main wall and which defines a fluid passageway therethrough. The tubular branch wall includes an elongate tubular extent and a contiguous flared tubular extent. The tubular branch wall is secured to the tubular main wall at the flared tubular extent to establish fluid communication between the passageways of the tubular main wall and the tubular branch wall. The flared tubular extent includes a gradual increase in diameter with respect to the tubular branch extent to provide a seamless and substantially fluid-tight transition between the tubular main wall and the tubular branch wall along the flared tubular extent.

A soft and pliable surgical support mesh exhibiting increased resistance to inhabitation of infectious matter. The mesh includes a support trellis formed of multifilament yarns wherein the interstitial voids located between the filaments of said yarns are enclosed within an infection-impervious matrix. The meshes may be designed to be extremely thin yet retain the requisite strength for repairing soft tissue, which allows for a low profile when folded for delivery.

Method of forming an implantable tubular prosthesis

A radially self-expanding implantable intraluminal device formed from a hollow tubular braid. The intraluminal device may be used in a variety of medical procedures which require a passageway to be maintained in an open position or which require reinforcement, support or a bypass conduit such as in blood vessels weakened by disease. The intraluminal device is longitudinally expanded or radially collapsed for ease of insertion into a lumen and upon alignment within the lumen, the intraluminal device radially self-expands to come into intimate contact with the inner surface of the lumen.
