摘要:
The present invention includes a braided stent and method of making the same. The braided stent has an integral retrieval and/or repositioning member. The stent includes a first open end, a second open end and a tubular body therebetween. The retrieval and/or repositioning member extends from and is interbraided into the braided tubular body. The retrieval and/or repositioning member includes an elongated portion extending from the first open end and a second section interlooping circumferentially about the first open end such that force exerted on the elongated portion causes radially contraction of the stent end and stent body.
摘要:
A braided stent (24) comprising a plurality of elongate filaments (20) inter-braided to form a braided tubular structure, the filaments (20) being inter-braided at a braiding angle (ß) formed at crossing filament locations, the braided tubular structure comprising a first portion (40) having a first diameter, a second portion (42) having a second diameter which is different from the first diameter and a transition portion disposed between the first portion and the second portion; and wherein the braiding angle (ß) in the first portion (40), the braiding angle (ß) in the second portion (42), and the braiding angle (ß) in the transition portion are within 5 degrees of one another.
摘要:
A method of braiding a stent includes braiding a number of elongate filaments around a mandrel using tensioned braiding carriers without spooling the filaments to the tensioned braiding carriers to form a braided stent having atraumatic ends.
摘要:
A stent, the stent comprising a first coating composition comprising at least one bioadhesive and a second coating composition disposed over the first coating composition, the second coating composition comprising at least one biodegradable polymer.
