Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
109 words
A vascular graft comprising: a perforate tubular frame (102) having a proximal end, a distal end, and a
lumen therebetween, and an inner liner (108) extending from a near-proximal location on the lumen
to a near-distal location on the lumen, wherein the liner (108) covers the lumen of the
tubular frame (102) over the entire distance from said near-proximal location to said
near-distal location, characterised in that said frame (102) includes a plurality of
adjacent radially compressible band members (104) not directly connected to each
other, and wherein the band members (104) are secured independently to the inner
liner (108) which thereby maintains the axial integrity of the graft.
Claim 2
Dependent Claim
109 words
A vascular graft comprising: a perforate tubular frame (202) having a proximal end, a distal end, and a
lumen therebetween, and an inner liner (206) extending from a near-proximal location on the lumen
to a near-distal location on the lumen, wherein the liner (206) covers the lumen of the
tubular frame (202) over the entire distance from said near-proximal location to said
near-distal location, characterised in that said frame (202) includes a plurality of
adjacent laterally compressible axial members (204) not directly connected to each
other, and wherein the axial members (204) are secured independently to the inner
liner (206) which thereby maintains the radial integrity of the graft.
Claim 3
Dependent Claim
19 words
A vascular graft as in claim 2, wherein the axial members (204) each
comprise a plurality of diamond-shaped elements.
Claim 4
Dependent Claim
77 words
A vascular graft as in one of the claims 1 to 3, wherein the liner (108,
206) is circumferentially sealed to the perforate tubular frame (102, 202) at at least
one of said near-proximal and near-distal locations, and is spaced-inward from an
end of the perforate tubular frame (102, 202) by a distance in the range from 1 mm to
20 mm, wherein at least one terminal portion of the perforate tubular frame (102,
202) remains uncovered.
Claim 5
Dependent Claim
30 words
A vascular graft as in one of the claims 1 to 4, wherein the independent
band members (104) or the axial members (204) are stitched to the liner (108, 206).
Claim 6
Dependent Claim
43 words
A vascular graft as in one of the claims 1 to 5, wherein the band
members (104) or the axial members (204) are secured to the inner liner (108, 206)
by an outer liner (110, 208) sealed to the inner liner (108, 206).
