Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
72 words
An intraluminal member for insertion into a body lumen, the intraluminal member including a segment of tube having a longitudinal axis, said segment and a lumen comprising: a wall helical coil extending coaxially with the longitudinal axis and enbedded in soil wall; the coil having a plurality of turns along a length of the axis with adjacent turns having opposing surfaces; bridging members tying at least selected ones of the adjacent turns.
Claim 2
Dependent Claim
72 words
An intraluminal member for insertion into a body lumen, the intraluminal member including a segment of tube having a longitudinal axis, said segment and a lumen comprising: a wall helical coil extending coaxially with the longitudinal axis and enbedded in soil wall; the coil having a plurality of turns along a length of the axis with adjacent turns having opposing surfaces; bridging members tying at least selected ones of the adjacent turns.
Claim 3
Dependent Claim
22 words
An intraluminal member according to claim 1 wherein both the coil and the bridging members are contained on a common cylindrical surface.
