Abstract

Medical devices and delivery systems for delivering medical devices to a target location within a subject. In some embodiments the medical devices can be locked in a fully deployed and locked configuration. In some embodiments the delivery systems are configured with a single actuator to control the movement of multiple components of the delivery system. In some embodiments the actuator controls the independent and dependent movement of multiple components of the delivery system.

Claims

1. (canceled)

2. A medical device system, comprising:

a delivery system including an outer sheath and an inner member slidably received within the outer sheath, the inner member having a detent proximate a distal end of the inner member; and

a replacement heart valve implant including an expandable anchoring element, the expandable anchoring element being releasably coupled to the distal end of the inner member;

wherein the expandable anchoring element is releasable from the inner member when the detent proximate the distal end of the inner member is disposed outside of the outer sheath.

3. The medical device system of claim 2, wherein expandable anchoring element is configured to shift between a collapsed delivery configuration and an expanded deployed configuration.

4. The medical device system of claim 2, wherein the replacement heart valve implant includes a plurality of valve leaflets disposed within the expandable anchoring element.

5. The medical device system of claim 2, wherein the detent proximate the distal end of the inner member is an annular detent in an outer surface of the inner member.

6. The medical device system of claim 2, wherein the detent proximate the distal end of the inner member includes multiple detents in an outer surface of the inner member.

7. The medical device system of claim 2, wherein the delivery system includes a handle disposed at a proximal end of the outer sheath.

8. The medical device system of claim 2, wherein the expandable anchoring element is releasably coupled to the distal end of the inner member at multiple discrete locations.

9. The medical device system of claim 2, wherein the expandable anchoring element includes a plurality of openings configured to engage a portion of the inner member.

10. The medical device system of claim 9, wherein the portion of the inner member includes a flexible member configured to extend through one of the plurality of openings.

11. The medical device of claim 10, wherein the flexible member includes an enlarged element at its distal end.

12. The medical device of claim 11, wherein the enlarged element of the flexible member is configured to engage the detent proximate the distal end of the inner member to releasably couple the expandable anchoring element to the distal end of the inner member.

13. The medical device of claim 10, wherein the portion of the inner member includes a plurality of flexible members, each flexible member corresponding to one of the plurality of openings.

14. The medical device of claim 13, wherein the inner member includes a plurality of detents proximate a distal end of the inner member, each flexible member being configured to engage one of the plurality of detents to releasably couple the expandable anchoring element to the distal end of the inner member.

15. The medical device of claim 13, wherein the plurality of flexible members each includes an enlarged element at its distal end.
