Filed:

Nov 2, 1999

Appl. No.:

09/431313

Inventors:

Jun Yang - Dove Canyon CA
George Guo - Dove Canyon CA

Assignee:

AV Healing LLC - Dove Canyon CA

International Classification:

A61F 206

US Classification:

623 113, 623 132

Abstract:

A graft system is provided that includes either a support ring or a support sleeve that is used in providing transitional support to either an end or a side of a graft or a host vessel. The support ring is provided with a generally cylindrical wall and defining a passageway that is adapted for receiving an end of a vein graft or an end of a host vessel. The support ring has a first end and a second end, with the thickness of the wall being greater at the first end than at the second end. The support sleeve is provided with a first side edge, a second side edge, and an opening. The support sleeve surrounds a side opening of a graft or host vessel so that the opening of the support sleeve is aligned with the side opening of the graft or host vessel. The thickness of the support sleeve is greater at the opening than at the first and second side edges.

Inventors:

Jun Yang - Dove Canyon CA 92679

International Classification:

A61F 206

US Classification:

623 142, 623 113

Abstract:

A prosthesis has a cylindrical stent, and a cover provided about the outer periphery of the stent. The cover has at least two layers of materials, with at least one layer of material being permeable to drugs. The layers of material can define at least one chamber therebetween, with a drug loaded into the at least one chamber. Alternatively, the drug can be loaded into the material of one or more layers.

Inventors:

Jun Yang - Dove Canyon CA 92679

International Classification:

A61F 206

US Classification:

623 142, 623 113

Abstract:

A prosthesis has a stent, and a cover that covers a portion of the stent. The cover has at least two layers of materials that can define at least one chamber therebetween, with a drug loaded into the at least one chamber by a dug dispersing element. The cover can be provided inside the luminal walls of the stent, or the stent can be retained in the at least one chamber. The cover can also be deployed to treat vulnerable plaque.

US Classification:

623/011110, 623/013170, 623/014120, 623/016110

Abstract:

A tissue composition includes the subendothelial layer, the elastica interna, and at least a portion of the tunica media of a blood vessel harvested from a mammal, with the endothelial cells removed from the blood vessel. The tissue composition can also include a portion of the tunica adventitia of a blood vessel harvested from a mammal. The tissue composition can be formed into a graft, a patch, a connective tissue for surgical repair, an orthopedic graft, and a substrate for cell growth, among other applications. The tissue composition can also be fluidized, or made into powdered form.

International Classification:

A61F002/06

US Classification:

623/001130, 623/001420

Abstract:

A prosthesis has a tubular stent and a cover provided about the outer periphery of the stent. The cover can be made from a water absorbent material, and/or a matrix of protein. The present invention also provides a method for treating a vulnerable plaque, the method including implanting the prosthesis over the vulnerable plaque.

Appl. No.:

Inventors:

Jun Yang - Dove Canyon CA, US

International Classification:

A61F002/08

US Classification:

623/013170, 623/902000, 623/901000

Abstract:

A method of forming an elongated graft element includes procuring a tubular tissue from a mammal, with the tubular tissue having a longitudinal axis, and a distal edge and a proximal end on opposing ends of the longitudinal axis. Thereafter, the tubular tissue is split along a line that is parallel to the longitudinal axis to form a sheet, and the distal edge and the proximal edge are approximated towards each other to form an elongated graft element. The elongated graft element has a longitudinal axis that comprises the circumferential orientation of the tubular tissue, with the circumferential orientation being transverse to the longitudinal axis of the tubular tissue.
