Abstract

The invention is a stent-graft device having a support component with multiple turns of an undulating member where the undulations have a number of apexes. The graft component of the device is substantially coaxial with the support component and is attached to the support component so as to allow a number of the support component'"'"'s apexes to move relative to the graft.

Claims

1. A stent-graft, comprising:

a permanently implantable support component having multiple turns of an undulating member, each turn of said undulating member having multiple undulations defining multiple apexes, with undulations in one turn generally in-phase with undulations in an adjacent turn;

said support component having an expandable configuration and an expanded configuration,

a permanently implantable graft component permanently attached in-part to said support component at a number of attachment points which allow sliding of the support component relative to said graft component when said support component is in said expanded configuration,

said support component having a number of said multiple apexes which are unattached to said graft component and which can move longitudinally relative to said graft component,

said support component having a number of said multiple apexes which are unattached to said graft component and which can move longitudinally with respect to each other.

2. A stent-graft, according to claim 1, further comprising a support component which is a stent member.

3. A stent-graft, according to claim 2, wherein said stent-graft has both an expandable and an expanded configuration.

4. A stent-graft, according to claim 2, further comprising:

a flexible linkage slidably contacting said support component.

5. A stent-graft, comprising:

a permanently implantable stent member having an expandable and an expanded configuration,

a permanently implantable graft member permanently connected to said stent member in said expanded configuration,

said stent member having a plurality of turns of an undulating member, each turn of said undulating member having a plurality of undulations, said plurality of undulations having a plurality of apexes unattached to said graft member, with the undulations of a first turn generally in-phase with the undulations of a second adjacent turn, said apexes which are unattached can move longitudinally relative to a generally adjacent graft member surface.

6. A stent-graft, comprising:

a permanently implantable support component having multiple turns of an undulating member, each turn of said undulating member having multiple undulations defining multiple apexes, with undulations in one turn generally in-phase with undulations in an adjacent turn;

said support component having an expandable configuration and an expanded configuration,

a implantable graft component attached in-part to said support component at a number of attachment points which allow sliding of the support component relative to said graft component when said support component is in said expanded configuration,

said support component having a number of said multiple apexes which are unattached to said graft component and which can move longitudinally relative to said graft component,

said support component having a number of said multiple apexes which are unattached to said graft component and which can move longitudinally with respect to each other.
