Abstract

A seamless, self-expanding implantable device having a low profile is disclosed along with methods of making and using the same. The implantable device includes a frame cut out of a single piece of material that is formed into a three-dimensional shape. The implantable device may comprise an embolic filter, stent, or other implantable structure. The present invention also allows complicated frame structures to be easily formed from planar sheets of starting material, such as through laser cutting, stamping, photo-etching, or other cutting techniques.

Claims

1. An endovascular device comprising:

a seamless frame having a proximal end, a distal end and a longitudinal axis extending therebetween, said frame having a seamless support member circumscribing said axis and located between said proximal and distal ends, a first set of struts extending seamlessly from said support member towards said proximal end and a second set of struts extending seamlessly from said support member towards said distal end.

2. The device of claim 1, wherein at least one strut of said first and second struts sets includes radiopaque markers.

3. The filter according to claim 1, wherein said distally extending filter struts terminate at a common seamless distal end.

4. A device comprising:

a seamless frame having a proximal end, a distal end and a longitudinal axis extending therebetween, said frame having at least one seamless support member circumscribing said axis and located between said proximal and distal ends, at least one of a first set of struts extending seamlessly from said support member towards said proximal end and at least one of a second set of struts extending seamlessly from said support member towards said distal end.

5. The device according to claim 4, wherein a plurality of seamless support members circumscribe said axis.

6. The device according to claim 4, wherein at least one of said struts of said first and second sets of struts and said at least one support member includes at least one of an integral articulation member and a radio-opaque marker.

7. The device according to claim 4, further including at least one seamless and integral articulation segment.

8. The device according to claim 6, further including a plurality of circumscribing members, and at least one integral articulation segment, one of which seamlessly interconnects said members.

9. An endovascular device comprising:

a seamless frame having open proximal and distal ends and a plurality of seamless integral struts formed from a common precursor material, at least some of said struts being seamlessly interconnected with one another to define a plurality of closed cells, and at least one of said plurality of seamless struts optionally having at least one articulation segment and/or radiopaque marker.

10. The device according to claim 9, wherein same frame is a tubular stent.

11. The device according to claim 9, wherein said frame includes integral articulation segments.

12. The device according to claim 9, wherein said frame includes radiopaque markers.

13. The device according to claim 9, wherein said frame includes integral articulation segments and radiopaque markers.
