1. A clot capture system, comprising:
- a plurality of axially spaced-apart anchors;
a shape memory tubular body comprising a first end, a second end, and an axial length therebetween, the first end having an opening, wherein the shape memory tubular body is compressed in a compressed configuration,wherein the shape memory tubular body is transformable to a first expanded configuration in which the first end is expanded, wherein the second end and a portion of the shape memory tubular body is compressed in the first expanded configuration, wherein the shape memory tubular body has a first expanded axial length in the first expanded configuration extending from the first end to a fold, wherein the fold forms the distal end of the shape memory tubular body in the first expanded configuration, wherein the first end and the second end are proximal to the distal end in the first expanded configuration,wherein the shape memory tubular body is transformable to a second expanded configuration in which the shape memory tubular body has a second expanded axial length greater than the first expanded axial length, wherein the shape memory tubular body circumscribes at least one anchor of the plurality of axially spaced-apart anchors in the second expanded configuration.
