Axial lengthening thrombus capture system
First Claim
Patent Images
1. A material capture system, comprising:
- a tubular body comprising a first end and a second end, the first end having an opening,wherein the tubular body comprises a first configuration in which the first end is expanded and the tubular body has a first expanded axial length, wherein the second end is compressed in the first configuration, wherein the tubular body has a folded portion between the first end and the second end such that a compressed portion of the tubular body is within an expanded portion of the tubular body, wherein the tubular body is configured to surround a thrombus in the first configuration,wherein, when the thrombus is surrounded by the tubular body, the tubular body is configured to redistribute the thrombus by transforming to a second configuration in which the tubular body has a second expanded axial length greater than the first expanded axial length, and wherein the folded portion is configured to move away from the thrombus to create additional space within the expanded portion of the tubular body,wherein the tubular body is configured to transform to a third configuration in which the tubular body has a third expanded axial length less than the second expanded axial length.

10. A method of using a clot capture system to redistribute a thrombus, comprising:
-
providing a tubular body comprising a first end and a second end, the first end having an opening, wherein the tubular body comprises a first configuration in which the first end is expanded and the tubular body has a first expanded axial length, wherein the second end is compressed in the first configuration, wherein the tubular body has a folded portion between the first end and the second end such that a compressed portion of the tubular body is within an expanded portion of the tubular body, wherein the tubular body surrounds a thrombus in the first configuration, redistributing a thrombus by transforming the tubular body to a second configuration in which the tubular body has a second expanded axial length greater than the first expanded axial length, wherein the folded portion is moved away from the thrombus to create additional space within the expanded portion of the tubular body, and transforming the tubular body to a third configuration in which the tubular body has a third expanded axial length less than the second expanded axial length. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
