Abstract

Medical devices and methods for making and using medical devices are disclosed. An example system for delivering an implantable medical device includes a handle member including a seal assembly, wherein the seal assembly includes a turnbuckle assembly including a stationary member and a cap coupled to the stationary member. Further, the stationary member is coupled to an inner member and the cap is coupled to an exoskeleton disposed along an outer surface of the inner member. Additionally, the cap is designed to shift relative to the stationary member such that the exoskeleton is put in compression.

First claim

What is claimed is:

1. A system for delivering an implantable medical device, comprising:
a handle member including a seal assembly, wherein the seal assembly is disposed within the handle member, and wherein the seal assembly includes:
a turnbuckle assembly including a stationary member and a cap coupled to the stationary member;

wherein the stationary member is coupled to an inner member;
wherein the cap is coupled to an exoskeleton that includes a plurality of discrete segments engaged with one another disposed along an outer surface of the inner member; and
wherein the cap is designed to shift distally relative to the stationary member whereupon the exoskeleton is put in compression.

2. The system of claim 1 , wherein the cap is threadedly engaged with the stationary member.

3. The system of claim 1 , further comprising a hypotube positioned along the inner member, wherein the hypotube is positioned between the cap and the exoskeleton.

4. The system of claim 3 , wherein the cap includes a protrusion configured to engage a proximal portion of the hypotube.

5. The system of claim 3 , wherein the cap includes a first seal, and wherein the first seal is disposed along an outer surface of the hypotube.

6. The system of claim 1 , wherein the stationary member includes a distal tip region configured to engage a proximal portion of the inner member.

7. The system of claim 1 , wherein the stationary member includes a recessed region, and wherein the recessed region is designed to mate with a protrusion in the handle member.

8. The system of claim 1 , wherein the stationary member is configured to prevent the inner member from shifting with respect to the handle member.

9. A system for delivering an implantable medical device, comprising:
a deployment sheath;
an inner member disposed within a portion of the deployment sheath; and
a handle coupled to the deployment sheath, wherein the handle includes a seal assembly disposed within the handle, and wherein the seal assembly includes:
a first actuating assembly, wherein the first actuating assembly is configured to receive the deployment sheath;
a second actuating assembly, wherein the second actuating assembly is configured to receive an actuating shaft; and
a turnbuckle assembly including a cap and a stationary member;
wherein the turnbuckle assembly is configured to compress an exoskeleton positioned along the inner member.

10. The system of claim 9 , wherein the cap is designed to shift distally with respect to the stationary member.

11. The system of claim 10 , wherein the exoskeleton includes a plurality of discrete segments engaged with one another, and wherein shifting the cap distally compresses the exoskeleton together.

12. The system of claim 10 , wherein the cap is threadedly engaged with the stationary member.

13. The system of claim 11 , further comprising a hypotube positioned along the inner member, wherein the hypotube is positioned between the cap and the exoskeleton.

14. The system of claim 13 , wherein the cap includes a protrusion configured to engage a proximal portion of the hypotube.

15. The system of claim 13 , wherein the cap includes a first seal, and wherein the first seal is disposed along an outer surface of the hypotube.

16. The system of claim 10 , wherein the stationary member includes a distal tip region configured to engage a proximal portion of the inner member.

17. The system of claim 10 , wherein the stationary member includes a recessed region, and wherein the recessed region is designed to mate with a protrusion in the handle.
