Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
124 words
An expandable intraluminal stent (10) for
implanting in a body lumen, comprising: a first stent section (11) having at least one
cylindrical element (13) ; a second stent section (12) adjacent said first
stent section (11), said second stent section (12)
having at least one cylindrical element (13); a plurality of connecting members (20) connecting
said first and second stent sections (11,12) back to
back; and a weakened portion (21) in at least some of said
connecting members (20), said connecting members (20)
being deformable at said weakened portion (21) when
subject to a compressive force to form a plurality of
projecting barbs (22), the overall length of the stent
(10) in the unexpanded configuration and in the
expanded configuration being substantially the same.
Claim 2
Dependent Claim
22 words
The intravascular stent of claim 1, wherein said
weakened portion (21) includes at least one notch in
said connecting members (20) .
Claim 3
Dependent Claim
33 words
The intravascular stent of claim 1, wherein said
stent (10) has a smooth outer surface having no
projections or rough edges and a first, unexpanded
diameter providing a low profile for intraluminal
delivery.
Claim 4
Dependent Claim
38 words
The intravascular stent of claim 1, wherein said
stent (10) has a second, expanded diameter so that
said outer surface of said stent (10) contacts the
body lumen and said plurality of projecting barbs
contact the body lumen.
Claim 5
Dependent Claim
20 words
The intravascular stent of claim 4, wherein said
plurality of projecting barbs (22) are capable of
penetrating the body lumen.
Claim 6
Dependent Claim
17 words
The intravascular stent of claim 1, wherein said
stent (10) is attached to a tubular graft (35).
Claim 7
Dependent Claim
18 words
The intravascular stent of claim 1 wherein said
stent (10) is formed from a single piece of tubing.
Claim 8
Dependent Claim
18 words
The intravascular stent of claim 1, wherein said
stent (10) is formed from a flat sheet of material.
Claim 9
Dependent Claim
53 words
The intravascular stent of claim 8, wherein said
flat sheet of material has a first longitudinal edge
and a second longitudinal edge, and said stent (10) is
rolled into a cylindrical configuration from said flat
sheet of material so that said first longitudinal edge
abuts said second longitudinal edge and is attached
thereto.
Claim 10
Dependent Claim
35 words
The intravascular stent of claim 1, wherein said
first stent section (11) and said second stent section
(12) are expanded from within causing said connecting
members (20) having a weakened portion (21) to deform
outwardly.
Claim 11
Dependent Claim
40 words
The intravascular stent of claim 1, wherein said
first stent section (11) is twisted relative to said
second stent section (12) in order to deform said
connecting members (20) having a weakened portion (21)
and form said projecting barbs (22).
Claim 12
Dependent Claim
21 words
The intravascular stent of claim 1, wherein at
least some of said connecting members (20) have a
plurality of notches (21).
