Abstract

Prosthetic valve introducer systems and methods for deploying a heart valve prosthesis within a body lumen are disclosed. In certain embodiments, the valve introducer can include a delivery shaft to house a prosthetic valve and a distal tip, and a deployment element to push a prosthetic valve out of the distal tip of the delivery shaft. The valve introducer can include at least one finger gripping element. The delivery shaft can be inserted into a body lumen and advanced to a desired deployment location. In certain embodiments, the prosthetic valve can be deployed by pushing the deployment element in a distal direction, thereby pushing the prosthetic valve out of the distal tip of the delivery shaft.

Claims

1. A prosthetic valve introducer comprising:

a delivery shaft comprising;

a tubular member configured to house a prosthetic valve; and

a distal tip;

a deployment element configured to push a prosthetic valve out of the distal tip of the delivery shaft; and

a prosthetic valve.

2. The prosthetic valve introducer of claim 1, further comprising at least one finger gripping element connected to the delivery shaft.

3. A prosthetic valve introducer system, the valve introducer comprising:

a handle comprising;

a deployment element housing;

a deployment element; and

at least one finger gripping element connected to the deployment element housing; and

a delivery shaft comprising;

a tubular member; and

a distal tip; and

a prosthetic valve,

wherein the deployment element is configured to deploy the prosthetic valve from the delivery shaft.

4. The prosthetic valve introducer system of claim 3, wherein the delivery shaft further comprises a housing capsule for the prosthetic valve.

5. The prosthetic valve introducer system of claim 3, wherein the distal tip is an atraumatic tip.

6. The prosthetic valve introducer system of claim 3, wherein the finger gripping element comprises an interior gripping surface and an exterior gripping surface.

7. The prosthetic valve introducer system of claim 6, wherein the interior gripping surface is configured to allow insertion of a finger.

8. The prosthetic valve introducer system of claim 3, wherein the deployment element comprises a shaft with a proximal end.

9. The prosthetic valve introducer system of claim 8, wherein the proximal end of the deployment element comprises a flat surface.

10. The prosthetic valve introducer system of claim 8, wherein the proximal end of the deployment element comprises a ring element configured to allow insertion of a finger.

11. The prosthetic valve introducer system of claim 8, wherein the shaft is slidably engaged with an interior surface of the deployment element housing.

12. The prosthetic valve introducer system of claim 3, further comprising a hemostatic valve configured to provide access to a body lumen.

13. The prosthetic valve introducer system of claim 3, wherein the handle further comprises an access port.

14. The prosthetic valve introducer system of claim 3, wherein the prosthetic valve is a self-expanding prosthetic heart valve.

15. A method of implanting a heart valve prosthesis with a valve introducer, the valve introducer comprising:

a delivery shaft comprising;

a tubular member; and

a distal tip;

a deployment element configured to deploy a heart valve prosthesis from the delivery shaft; and

a heart valve prosthesis;

the method comprising;

inserting the delivery shaft into a body lumen at an insertion point until the distal tip reaches a deployment location; and

activating the deployment element to deploy the heart valve prosthesis from the delivery shaft.

16. The method of claim 15, wherein inserting the delivery shaft into the body lumen comprises puncturing a surface of the body lumen with the distal tip of the delivery shaft at the insertion point.

17. The method of claim 15, further comprising removing the valve introducer from the body lumen after deploying the heart valve prosthesis.

18. The method of claim 15, further comprising securing a hemostatic valve at the insertion point and inserting the delivery shaft through the hemostatic valve and into the body lumen.

19. The method of claim 15, wherein activating the deployment element comprises pushing the deployment element in a distal direction to deploy the heart valve prosthesis out of the distal tip of the delivery shaft.

20. The method of claim 15, wherein activating the deployment element comprises pulling the deployment element in a proximal direction to retract the delivery shaft to deploy the heart valve prosthesis.
