Abstract
An expansion ring for a braided stent includes a plurality of elongated forked frame elements forming the expansion ring. Each of the frame elements includes first and second legs extending in one direction and connected together at a junction portion forming a fulcrum allowing compression of the frame elements, and each of the frame elements are threaded through interstices in a tubular body of the braided stent so that the junction portions engage the tubular body of the braided stent. Each of the frame elements is connected sequentially to adjacent frame elements at the ends of the first and second legs, and the expansion ring has a compressed configuration with a first diameter and an expanded configuration with a second diameter larger than the first diameter.
Claims25
An expansion ring for a braided stent, the expansion ring comprising:
- a plurality of elongated forked frame elements, each of said plurality of elongated forked frame elements having a fulcrum allowing compression of said plurality of elongated forked frame elements, each of said plurality of elongated forked frame elements including first and second legs having first and second terminations extending in a first direction on one side of each of said elongated forked members, said first and second legs of each of said plurality of elongated forked frame elements being connected together at a junction portion forming said fulcrum therebetween at an opposing second side of each of said plurality of elongated forked frame elements, said junction portion extending in an opposing second direction;
- and
- each of said plurality of elongated forked frame elements being connected sequentially to adjacent ones of said plurality of elongated forked frame elements at said first and second terminations of said first and second legs to form the expansion ring, said plurality of elongated forked frame elements having a compressed configuration having a first diameter and an expanded configuration having a second diameter larger than said first diameter.
A braided stent, comprising:
- a tubular braided stent body having a proximal end, a distal end, and an inner lumen, said tubular braided stent body being formed from a plurality of elongate members, said plurality of elongate members being braided to form a plurality of interstices therebetween;
- and
- at least one expansion ring connected to at least one of said proximal end and said distal end of said tubular braided stent body, said at least one expansion ring including a plurality of elongated forked frame elements each having a fulcrum allowing compression of said plurality of elongated forked frame elements, each of said plurality of elongated forked frame elements being threaded through at least one of said interstices of a portion of at least one of said proximal end and said distal end of said tubular braided stent body, each of said plurality of elongated forked frame elements including first and second legs having first and second ends extending in a first direction on one side of each of said elongated forked members, said first and second legs being connected together at a junction portion forming a fulcrum therebetween at an opposing second side of each of said elongated forked members, said junction portion extending in an opposing second direction, each of said first legs of said plurality of elongated forked frame elements extending inside said lumen of said tubular braided stent body, and each of said second legs of said plurality of elongated forked frame elements extending outside said lumen of said tubular braided stent body, such that said junction portions of said plurality of elongated forked frame elements engage said tubular braided stent body through said interstices of said tubular braided stent body, and each of said plurality of elongated forked frame elements being connected sequentially to adjacent ones of said plurality of elongated forked frame elements at said first and second terminations of said first and second legs to form said at least one expansion ring, and said at least one expansion ring having a compressed configuration having a first diameter and an expanded configuration having a second diameter larger than said first diameter.
