Abstract

Claims (19)

1 . A medical implant for occluding a left atrial appendage, comprising:

an expandable framework configured to shift radially relative to a central longitudinal axis between a first configuration and a second configuration; and

an occlusive element secured to the expandable framework;

wherein the expandable framework includes a plurality of strut groups, each strut group comprising a longitudinal axis extending from a first joint to a second joint, a first strut extending from the first joint to the second joint, a second strut extending from the first joint to the second joint, and a third strut disposed between the first strut and the second strut;

wherein the first strut is disposed in a first strut first position in the first configuration and a first strut second position in the second configuration, the first strut moving laterally in a first direction relative to the longitudinal axis from the first strut first position to the first strut second position;

wherein the second strut is disposed in a second strut first position in the first configuration and a second strut second position in the second configuration, the second strut moving laterally in a second direction relative to the longitudinal axis from the second strut first position to the second strut second position;

wherein the third strut is disposed in a third strut first position in the first configuration and is configured to shift radially relative to the longitudinal axis from the third strut first position in the first configuration to a third strut second position in the second configuration;

wherein the third strut second position is disposed radially inward from the longitudinal axis; and

wherein in the second configuration, the third strut is configured to selectively shift radially inward from the third strut second position to a third strut third position radially outward of the third strut first position.

2 . The medical implant of claim 1 , wherein the third strut is selectively shifted from the third strut second position to the third strut third position using an actuation element.

3 . The medical implant of claim 2 , wherein the actuation element is an expandable member disposed within the expandable framework.

4 . The medical implant of claim 2 , wherein the actuation element is at least one tether disposed within the expandable framework.

5 . The medical implant of claim 4 , wherein the third strut is pulled radially inward by the at least one tether as the expandable framework shifts from the first configuration to the second configuration.

6 . The medical implant of claim 5 , wherein subsequently releasing the at least one tether in the second configuration permits the third strut to shift to the third strut third position.

7 . The medical implant of claim 1 , wherein the third strut second position is disposed radially outward from the longitudinal axis.

8 . The medical implant of claim 1 , wherein the third strut of each strut group includes at least one anchor member extending radially outward from the third strut in the second configuration.

9 . The medical implant of claim 1 , wherein the plurality of strut groups defines a body region of the expandable framework.

10 . The medical implant of claim 1 , wherein the plurality of strut groups defines a shoulder region of the expandable framework.

11 . The medical implant of claim 1 , wherein in the first configuration, the first strut, the second strut, and the third strut of each strut group are of equal length.
