Abstract
An intraluminal support device for providing artificial support to a body vessel is provided. The support device includes a support frame having a substantially uniform circumference along its length, and a graft material disposed on a portion of the support frame. The graft material spans at least a portion of the length of the support frame and extends only a partial distance along the circumference of the support frame. Radiopaque markers can be disposed on the support frame adjacent the graft material to facilitate orientating the device in a body vessel such that the graft material is in a desired position relative to a treatment site of the vessel. A delivery apparatus for introducing such an intraluminal support device to a vessel is also provided.
Claims38
An intraluminal support device for providing support to a body vessel, comprising:
- a support frame comprising a tubular structure formed of one or more frame threads and having a length and a substantially uniform circumference;
- and
- a graft material disposed on a portion of the support frame and spanning at least a portion of the length, the graft material extending only a partial distance along the circumference of the support frame.
An intraluminal support device, comprising:
- a frame thread formed into a plurality of interleaved ring segments joined together by curved regions to form a tubular structure having a first end, a second end, and defining a plurality of cells that provide a substantially uniform circumference to the tubular structure;
- and
- a graft material extending only a partial distance along the circumference of the tubular structure and from the first end to the second end such that the graft material spans a portion of each cell of the plurality of cells.
An intraluminal support device, comprising:
- a support frame formed from a pattern in a sheet of biocompatible material, the support frame comprising a tubular structure having a first end, a second end, and defining a plurality of cells that provide a substantially uniform circumference to the support frame;
- and
- a graft material extending only a partial distance along the circumference of the support frame and from the first end to the second end such that the graft material spans a portion of each cell of the plurality of cells.
An apparatus for delivering an intraluminal support device to a vessel, comprising:
- a first catheter having a first distal end;
- a balloon positioned on the first distal end;
- a support frame surrounding the balloon and comprising a tubular structure formed of one or more frame threads defining a plurality of cells that provide a substantially uniform circumference to the support frame;
- and
- a graft material disposed on a portion of the support frame and spanning at least a portion of one or more cells of the plurality of cells, the graft material extending only a partial distance along the circumference of the support frame;
- wherein the balloon is adapted to circumferentially expand the support frame upon inflation.
An intraluminal support device, comprising:
- a support frame comprising a tubular structure having a uniform circumference and formed of a pattern in a sheet of biocompatible material, the pattern defining first and second series of opposing fingers connected by a longitudinal support;
- and
- a graft material attached to first and second fingers of the first series of opposing fingers and extending only a partial distance along the circumference of the support frame.
