Trans-Aortic Surgical Syringe-Type Device for Deployment of a Prosthetic Valve
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.
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.
