摘要:
An insertable stent (10) is provided for joining together, and facilitating healing of adjacent tissues (18, 20). Typically, the tissues are mammalian tissues. The inserted stent is made from completely non-toxic, bio-compatible and blood compatible materials. Each of the tissues employed herein defines an internal cavity (22). The insertable stent body defines a bore. The bore permits fluid to pass through the inserted stent body (12). In use, the inserted stent (12) is introduced into the internal cavities of the tissues (22). The inserted stent body fits within the confines of, and in contact with, each of the adjacent tissues. Typically, at least a portion of the inserted stent body (12) is fusible to the adjacent tissues (18, 20) for facilitating healing of these tissues.

摘要:
A bioprosthetic stent graft (1) is disclosed, having a stent frame (10) and a biomaterial sheath (20) suturelessly bonded to the stent frame. Sutureless bonding avoids sutures and substantially reducing medical complications in implantation of the stent graft. A device and method for manufacturing the stent graft further is disclosed. A mandrel (60) is employed for shaping the stent graft, and means (70) for irradiating the biomaterial effects sutureless bonding.
摘要:
The present invention provides an absorbent wound dressing assembly that can be used to stanch, seal, or stabilize a site of tissue injury, tissue trauma, or tissue access. The wound dressing assembly is flexible so that it can be adapted and used to fit in narrow and small wound sites. Generally the wound dressing assembly comprises a flexible carrier material that is impregnated with a non-mammalian material for control of severe bleeding. The preferred non-mammalian material is poly [β- (1→4) -2-amino-2-deoxy-D-glucopyranose] more commonly referred to as chitosan.

A bioprosthetic valve graft (1) comprises a valve frame (10) and valve flaps (12), the latter acting to open or close a valve aperture (14) to directionally control fluid flow through the bioprosthesis (1). The bioprosthetic valve graft (1) comprises a biomaterial suturelessly bonded to the valve frame (10), avoiding sutures and substantially reducing medical complications in implantations.
