Abstract
The present invention relates to a stent-graft where the stent is formed from a self-expanding material and is coaxially and slidably coupled to the graft component which contains collagen. At least one flexible linkage is provided for coupling the stent and graft together in the slidable manner.
Claims24
A device comprising:
- a support component having multiple turns of an undulating member, said undulating member being formed from a single continuous wire, each turn of said undulating member having multiple undulations which define multiple apexes, wherein undulations in one turn are generally in-phase with undulations in an adjacent turn;
- and
- a tubular, graft component substantially coaxial with said support component, said tubular graft component containing collagen and being slidably attached to said support component to allow said undulations to move longitudinally relative to said graft component.
A device comprising:
- a support component comprising a helically configured member having multiple helical turns and multiple undulations defining multiple apexes;
- a tubular, graft component substantially coaxial with said support component, said tubular graft component containing collagen and being slidably attached to said support component which allows said undulations to move longitudinally relative to said graft component;
- and
- at least one flexible link passing through adjacent helical turns of said support component to maintain said undulations generally in-phase.

A device comprising:
- a support component having multiple turns of an undulating member, said undulating member being formed from a single continuous wire, each turn of said undulating member having multiple undulations which define multiple apexes, wherein apexes in one turn are longitudinally movable with respect to apexes in an adjacent turn, and wherein undulations in said one turn are generally in-phase with undulations in said adjacent turn;
- and
- a tubular, graft component substantially coaxial with said support component, said tubular graft component containing collagen and being slidably attached to said support component to allow said apexes to move longitudinally relative to said graft component.
