Abstract

A delivery system for an implantable medical device including a tether retaining feature having a bore. The system includes a connector having a top surface, a bottom surface, a rail extending in a proximal direction from the connector, and an aperture sized to receive the tether retaining feature and reduce movement of the connector with respect to the implantable medical device in a plane parallel to the aperture. A tether is sized to fit within the bore of the tether retaining feature. The tether acts against the top surface of the connector to retain the bottom surface of the connector proximal to the implantable medical device when the tether is located within the bore of the tether retaining feature. A method for delivering an implantable medical device including a tether retaining feature.

Claims

1. A delivery system for an implantable medical device including a tether retaining feature having a bore, the delivery system comprising:

a connector having a top surface, a bottom surface, a rail extending in a proximal direction from the connector, and an aperture sized to receive the tether retaining feature and reduce movement of the connector with respect to the implantable medical device in a plane parallel to the aperture; and

a tether sized to fit within the bore of the tether retaining feature;

wherein the tether acts against the top surface of the connector to retain the bottom surface of the connector proximal to the implantable medical device when the tether is located within the bore of the tether retaining feature.

2. The system of claim 1 wherein the rail comprises a plurality of rails extending proximally from the connector.

3. The system of claim 2 wherein the connector comprises a cross piece and a plurality of side pieces, and the plurality of side pieces is integral with the plurality of rails.

4. The system of claim 3 wherein the connector is comprised of flat ribbon wire.

5. The system of claim 4 wherein the flat ribbon wire has a width of approximately 0.010 inch and a thickness of approximately 0.005 inch.

6. The system of claim 3 wherein the connector is comprised of a round wire.

7. The system of claim 6 wherein the round wire has a diameter of approximately 0.007 inch.

8. The system of claim 1 wherein the connector comprises a plate.

9. The system of claim 1 wherein the connector includes a plurality of apertures and the implantable medical device includes a plurality of tether retaining features.

10. The system of claim 1 wherein the tether retaining feature includes an opening configured to allow insertion of the tether into the bore through the opening.

11. The system of claim 1 wherein the tether retaining feature is closed and the tether must be slid into the bore.

12. The system of claim 1 wherein the fit of the tether with the tether retaining feature is an interference fit.

13. The system of claim 1 wherein the fit of the tether with the tether retaining feature is loose.

14. A delivery system for an implantable medical device including a tether retaining feature, the delivery system comprising a connector having an aperture sized to receive the tether retaining feature and a tether sized to fit within the tether retaining feature to releasably couple the connector to the implantable medical device.

15. The system of claim 14 further comprising a rail extending in a proximal direction from the connector.

16. The system of claim 14 further comprising an inner member having a leading face located proximal to a trailing face of the connector, wherein the inner member is configured to push the implantable medical device and includes a tether lumen sized to slideably receive the tether and a rail lumen sized to slideably receive the rail.

17. The system of claim 16 wherein the rail includes a proximal end coupled to the inner member.

18. The system of claim 16 wherein the rail comprises a plurality of rails and the inner member includes a plurality of rail lumens.

19. A method for delivering an implantable medical device including a tether retaining feature, the method comprising:

inserting the tether retaining feature into an aperture of a connector;

releaseably coupling the connector to the implantable medical device by inserting a tether into the tether retaining feature;

positioning the implantable medical device within a patient;

deploying an anchor coupled to the implantable medical device;

releasing the connector from the implantable medical device by sliding the tether through a bore of the tether retaining feature; and

removing the connector.

20. The method of claim 19 wherein the method further comprises delivering the implantable medical device through an elongated catheter having an inner lumen sized to slideably receive the implantable medical device.
