Assignee:

Advanced Bio Prosthetic Surfaces, Ltd. - San Antonio TX

International Classification:

A61F 206

US Classification:

623 113, 623 146

Abstract:

An implantable endoluminal device that is fabricated from materials that present a blood or body fluid and tissue contact surface that has controlled heterogeneities in material constitution. An endoluminal stent-graft and web-stent that is made of an monolithic material deposited into a monolayer and etched into regions of structural members and web regions subtending interstitial regions between the structural members. An endoluminal graft is also provided which is made of a biocompatible metal or metal-like material. The endoluminal stent-graft is characterized by having controlled heterogeneities in the stent material along the blood flow surface of the stent and the method of fabricating the stent using vacuum deposition methods.

Assignee:

Advanced Bio Prosthetic Surfaces, Ltd. - San Antonio TX

International Classification:

A61M 2900

US Classification:

606200

Abstract:

An embolic protection device includes a catheter body having a central longitudinal lumen, a guidewire positioned within the central longitudinal lumen, and a graft member that is generally tubular in shape in an undeployed state and generally frustroconical in shape in a deployed state. A plurality of openings are formed in the graft member and a plurality of arm members interconnect a proximal end of the graft member with the catheter body. A distal end of the graft member is connected to the guidewire or the atraumatic tip. The graft member may be fabricated of superelastic materials, plastically deformable materials or self-expanding materials and the plurality of openings are capable of diametric expansion and reduction proportionate to the degree of diametric expansion and reduction of a corresponding transverse cross-sectional region of the graft member when in the deployed state to capture emboli or particulate matter and minimize extrusion of the captured material through the openings in the graft member when the graft member is collapsed.

International Classification:

A61M 2900

US Classification:

606192

Abstract:

A metal balloon catheter having a main tubular body, a metal balloon proximate a distal end of the main tubular body, a central annulus extending along an entire longitudinal aspect of the catheter for accommodating a guidewire therethrough and an inflation annulus adjacent the central annulus which extends along the longitudinal axis of the main tubular body and terminates in fluid flow communication with an inflation chamber of the metal balloon. The metal balloon catheter may be either unitary integral metal catheter in which the main tubular body and the balloon are fabricated of metal, or it may consist of a polymeric main tubular body and a metal balloon.

Assignee:

Advanced Bio Prosthetic Surfaces, Ltd. - San Antonio TX

International Classification:

A61F002/06

US Classification:

623 118, 623 119

Abstract:

An implantable expandable medical device in which selected regions of the device are in a martensite phase and selected regions are in an austenite phase. The martensitic regions exhibit pseudoplastic behavior in vivo and may be deformed without recovery under in vivo body conditions. In contrast the austenitic regions exhibit superelastic behavior in vivo and will recover their pre-programmed configuration upon deformation or release of an applied strain.

Assignee:

Advanced Bio Prosthetic Surfaces, Ltd. - San Antonio TX

International Classification:

A61F002/06

US Classification:

623 113

Abstract:

Implantable medical grafts fabricated of metallic or pseudometallic films of biocompatible materials having a plurality of microperforations passing through the film in a pattern that imparts fabric-like qualities to the graft or permits the geometric deformation of the graft. The implantable graft is preferably fabricated by vacuum deposition of metallic and/or pseudometallic materials into either single or multi-layered structures with the plurality of microperforations either being formed during deposition or after deposition by selective removal of sections of the deposited film. The implantable medical grafts are suitable for use as endoluminal or surgical grafts and may be used as vascular grafts, stent-grafts, skin grafts, shunts, bone grafts, surgical patches, non-vascular conduits, valvular leaflets, filters, occlusion membranes, artificial sphincters, tendons and ligaments.
