TRANSCATHETER VALVE DELIVERY SYSTEM WITH SEPTUM HOLE CLOSURE TIP ASSEMBLY
First Claim
1. A delivery device for implanting a stented prosthetic heart valve, the device comprising:
- a support shaft having a distal region;
a retention assembly associated with the support shaft and configured to retain the stented prosthetic heart valve; and
a tip assembly releasably coupled to the distal region of the support shaft distal to the retention assembly;
wherein the delivery device is configured to permit in vivo release of the stented prosthetic heart valve and, in a separate action, actuate in vivo release of the tip assembly from a remainder of the delivery device.

Abstract
Transcatheter heart valve delivery systems having a tip assembly configured to close the hole or perforation made in a patient'"'"'s septal wall after transseptal delivery of a stented prosthetic heart valve to a defective heart valve (e.g., a mitral valve). The delivery device is configured to permit in vivo release of the tip assembly immediately after deployment of the stented prosthetic heart valve to implant the tip assembly into the septal wall proximate the hole through which the stented prosthetic heart valve is delivered. Methods of treating the defective heart valve, including closing the hole made during transseptal delivery of the stented prosthetic heart valve with the tip assembly of the delivery device are also disclosed.

13. A system for treating a defective heart valve via a trans-septal approach, the system comprising:
-
a delivery device including; a support shaft having a distal region, a retention assembly associated with the support shaft, and a tip assembly releasably coupled to the distal region of the support shaft; and a stented prosthetic heart valve compressed over the support shaft and retained by the retention assembly in a loaded arrangement of the delivery device; wherein the delivery device is configured to permit in vivo release of the stented prosthetic heart valve and the tip assembly from a remainder of the delivery device. - View Dependent Claims (14, 15, 16, 17)

18. A method of treating a defective heart valve of a patient, the method comprising:
-
providing a delivery device including a support shaft maintaining a stented prosthetic heart valve and having a tip assembly adjacent and distal to the prosthetic heart valve; forming a hole in a septum of a heart of the patient; directing the tip assembly and the stented prosthetic heart valve through the hole; deploying the prosthetic heart valve from the delivery device to implant the prosthetic heart valve at the defective heart valve; and implanting the tip assembly at the hole in the septum. - View Dependent Claims (19, 20)
