Abstract
Abstract A method of combining first and second self-expanding stents to form a stent assembly for insertion into a body passageway by: forming first and second stents each from a continuous first length of wire formed into a closed zig-zag configuration having an endless series of straight sections joined at their ends by a plurality of bends, the second stent having bends at one end defining eyes open at the straight sections of the second stent, engaging the eyes at one end of the second stent about bends at one end of the first stent and closing the eyes.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
129 words
A stent assembly (10) comprising: a first wire formed into a closed zig-zag configuration including: an endless series of straight sections (13) having opposite ends, said straight sections being joined by bends (14) at said opposite ends to form a stent; a set of eyes (20) formed at several of said bends at one of said opposite ends; and a thread (40) passing through successive ones of said set of eyes, wherein said stent is resiliently contractible into a smaller first shape for conveyance through a body passageway; and wherein said stent is resiliently expandable into a second shape in which the straight sections press against the walls of the body passageway, characterised in that said thread includes a pair of free ends (40a, 40b), trailing from said stent.
Claim 2
Dependent Claim
46 words
The stent assembly of claim 1, wherein: said second shape of said stent includes a circumference at said one of said opposite ends, said set of eyes being situated at said circumference; and said thread passes through successive eyes (20) at least 360° around said circumference.
Claim 3
Dependent Claim
19 words
The stent assembly of claim 2, wherein said thread passes through successive eyes (20) approximately 540° around said circumference.
Claim 4
Dependent Claim
29 words
The stent assembly of claim 1, wherein said free ends (40a, 40b) are sufficiently long to extend outside the body passageway when said stent is situated within the passageway.
Claim 5
Dependent Claim
133 words
The stent assembly (10) of claim 1, further comprising: a second wire (11'') formed into a closed zig-zag configuration including: a second endless series of straight sections having opposite ends, said straight sections being joined by bends (14'') at said opposite ends to form a second stent; a second set of eyes (20'') formed at several of said bends at one of said opposite ends; wherein said second stent is resiliently contractible into a smaller first shape for conveyance through a body passageway; wherein said second stent (10'') is resiliently expandable into a second shape in which the straight sections press against the walls of the body passageway; and wherein said second set of eyes (20'') of said second wire are engaged about said first wire (11') at one of said opposite ends.
Claim 6
Dependent Claim
50 words
The stent assembly of claim 5, wherein: said first wire (11') includes a third set of eyes formed at several bends at the other of said opposite ends of said first wire; and said second set of eyes of said second wire are interengaged with said third set of eyes.
