Abstract

Heart valve prosthesis recapture devices and methods for recapture are disclosed, which can be used for recapturing a partially deployed heart valve prosthesis. The recapture device comprises a recapture sleeve, configured to envelop and collapse a partially deployed heart valve prosthesis. The recapture sleeve comprises a distal end, configured to be securely attached to a guide wire, and a proximal end, comprising an opening along a longitudinal axis of the recapture sleeve. The opening can be configured to expand as it engages the heart valve prosthesis, and be biased toward a closed configuration. An attachment element can interface with the distal end of the recapture sleeve and be securely attached to a guide wire, such as by crimping. The recapture sleeve can include a support structure comprising at least one spine and a plurality of ribs.

Claims

1. A heart valve prosthesis recapture device comprising:

a heart valve prosthesis having a radially compressed configuration and a radially expanded configuration;

a valve delivery capsule, having a distal end and a proximally facing opening, wherein the valve delivery capsule is configured to maintain the heart valve prosthesis in the radially compressed configuration and wherein distal movement of the valve delivery capsule releases at least a portion of the heart valve prosthesis from therewithin;

a guide wire disposed through the valve delivery capsule;

a recapture sleeve including a distal end fixedly attached to the guide wire at a location distal of the valve delivery capsule and a proximal end having an opening along a longitudinal axis of the recapture sleeve,

wherein with the valve delivery capsule in a position such that the heart valve prosthesis is partially deployed proximal of the valve delivery capsule, the recapture sleeve is configured to be moved proximally from the location distal from the valve delivery capsule over the valve delivery capsule and over the partially deployed heart valve prosthesis to collapse the partially deployed heart valve prosthesis.

2. The recapture device of claim 1, wherein the recapture sleeve comprises a polymeric material or a metal sleeve.

3. The recapture device of claim 1, wherein at least the proximal end of the recapture sleeve is elastic, and wherein an elasticity of the proximal end of the recapture sleeve is greater than an elasticity of the distal end of the recapture sleeve.

4. The recapture device of claim 1, wherein the proximal end of the recapture sleeve is flared radially outward.

5. The recapture device of claim 1, wherein the opening at the proximal end of the recapture sleeve is biased toward a closed configuration.

6. The recapture device of claim 1, wherein the proximal opening further comprises a drawstring element capable of controlling the diameter of the opening.

7. The recapture device of claim 1, wherein an interior surface of the recapture sleeve is lubricated.

8. The recapture device of claim 1, wherein the recapture sleeve comprises:

a support structure;

a first covering on the outside of the support structure; and

a second covering on the inside of the support structure.

9. The recapture device of claim 1, further comprising an attachment element, which interfaces with the distal end of the recapture sleeve and is configured to be fixedly attached to a guide wire.

10. The recapture device of claim 9, wherein the attachment element is a laser cut metal tube configured to be crimped about a guide wire to fix the recapture sleeve to the guide wire.

11. The recapture device of claim 1, wherein the recapture sleeve comprises an expandable tube comprising an expandable fold configured to unfold upon engaging a heart valve prosthesis.
