Use of cold drawn PTFE yarns result in implantable prostheses that have excellent abrasion resistance, strength and lubricity properties. Useful textile constructions include weaves, knits, braids, filament windings, spun windings and combinations thereof. The prostheses of the present invention are lubricious and have characteristics that closely resemble the properties of a natural body lumen.

Abstract: 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.

Abstract: A woven sleeve is used for bundling elongated substrates. The illustrative embodiment is interwoven of monofilament warp members and fill yarns comprised of compliant material such as bulky multifilament yarn. Supplement monofilaments extending lengthwise of the fabric are separated into individual pieces, each including a section cradled in the compliant material of a fill yarn and are locked in the cradle position by at least one of the warp members. End sections of the individual pieces project outwardly and terminate in hooks which interlock with an exposed section of the compliant material to effect closure of the sleeve around the elongated substrates. A sleeve of the type described may also be provide with integral hooks to attach the sleeve to loop-type other loop material on a support surface.

Abstract: A method of manufacturing a woven textile having a structural member integrally woven therein. The structural member may be either straight or an undulating member which, although straight when secured to the textile, is trained to undergo a shape memory transformation back to its remembered undulating shape. The structural member is secured to the woven textile by displacing one or more given warp yarns in a first direction to create a structural member receiving gap, inserting the structural member into the gap by passing a structural member-insertion shuttle therethrough, and thereafter returning the displaced warp yarn or yarns to secure the structural member.

Abstract: A continuously woven web includes a first woven region interwoven with a plurality of yarns to define a first weave pattern and a second woven region forming a continuous weave with the first woven region and having a continuation of the yarns. The yarns are attached to the second woven region at a distal end thereof. The second woven region has a length defined by a length between a first end positioned adjacent a termination of the first weave pattern and the distal end. In the second woven region, the yarns have a greater elasticity in aggregate and a shorter length than the second woven region. Upon application of a tensile force to the webbing, the yarns in the second woven region may elongate to a length limited by the length of the second woven region.

Abstract: An elasticized double wall tubular cord includes an outer wall fabricated from a tube of woven material that is comprised of heavy duty, inelastic yarns, and an inner wall fabricated from a tube of woven material that is made partially of heavy duty, inelastic yarns and partially of elastic strands. The inner tube of woven material is stretchable lengthwise and attached to the outer tube of woven material along respective long edges when in stretched condition. The arrangement is such that when the inner tube of the tubular cord is in relaxed condition, the outer tube is compressed due to the compression force of the elastic strands of the inner tube for shortening the tubular cord.

Abstract: Graft prostheses are woven with cross-weave patterns to prevent unravelling and to increase suture hold strength. A vascular graft according to the invention is woven as a continuous tube by shuttling a continuous weft thread through a double-layer array of warp threads. As the weft thread is shuttled through the warp pattern, groups of warp threads are retained in parallel relationship to each other while interspersed pairs of warp threads are crossed over each other. This results in graft having normal weave patterns circumferentially alternating with cross-weave patterns.
