Abstract

Systems for delivering prosthetic heart valve devices and associated methods are disclosed herein. A delivery system configured in accordance with embodiments of the present technology can include, for example, an elongated catheter body, a delivery capsule carried by the elongated catheter body, and two fluid chambers within the delivery capsule. The delivery capsule can be hydraulically driven between a containment configuration for holding the prosthetic heart valve device and a deployment configuration for at least partially deploying the prosthetic heart valve device. For example, the delivery capsule can be urged towards the deployment configuration when fluid is removed from the first chamber and fluid is delivered into the second chamber, whereas the delivery capsule can be urged towards the containment configuration to resheathe the prosthetic heart valve device when fluid is removed from the second chamber and delivered into the first chamber.

First claim

I claim:

1. A system for delivering a prosthetic heart valve device for implantation at a native heart valve of a patient, the system comprising:
an elongated catheter body;
a delivery capsule coupled to the elongated catheter body and configured to contain the prosthetic heart valve device, wherein:
the delivery capsule is configured to be hydraulically driven between a containment configuration for holding the prosthetic heart valve device and a deployment configuration for deploying at least a portion of the prosthetic heart valve device,
the delivery capsule includes a housing and a platform that define, at least in part, a deployment chamber;

an end cap coupled to an end of the housing, the end cap configured to close an open end of the housing in the containment configuration and configured to be separated from the housing in the deployment configuration; and
an expandable member coupled to the elongated catheter body and distal to the delivery capsule, wherein the expandable member is configured to urge the delivery capsule towards the containment configuration and resheathe at least a portion of the prosthetic heart valve device when fluid is at least partially drained from the deployment chamber while fluid is delivered to the expandable member.

2. The system of claim 1 , wherein the delivery capsule is configured to substantially prevent translation of the prosthetic heart valve device relative to the elongated catheter body while the prosthetic heart valve device is at least partially resheathed.

3. The system of claim 1 , wherein the delivery capsule further comprises a containment chamber configured to contain the prosthetic heart valve device, and wherein the containment chamber is fluidically sealed from the deployment chamber via the platform.

4. The system of claim 1 , wherein the expandable member is a balloon.

5. A system for delivering a prosthetic heart valve device for implantation at a native heart valve of a patient, the system comprising:
an elongated catheter body;
a delivery capsule coupled to the elongated catheter body and configured to contain the prosthetic heart valve device, wherein:
the delivery capsule is configured to be hydraulically driven between a containment configuration for holding the prosthetic heart valve device and a deployment configuration for deploying at least a portion of the prosthetic heart valve device,
the delivery capsule includes a housing and a platform that define, at least in part, a deployment chamber;

an expandable member coupled to the elongated catheter body and distal to the delivery capsule; and
a manifold at a proximal end region of the elongated catheter body and configured to receive fluid for delivery to at least one of the deployment chamber or the expandable member, wherein the manifold comprises a first fluid lumen and first valve in fluid communication with the deployment chamber, and a second fluid lumen and a second valve in fluid communication with the expandable member,
wherein the expandable member is configured to urge the delivery capsule towards the containment configuration and resheathe at least a portion of the prosthetic heart valve device when fluid is at least partially drained from the deployment chamber while fluid is delivered to the expandable member.

6. The system of claim 5 , wherein the delivery capsule is configured to substantially prevent translation of the prosthetic heart valve device relative to the elongated catheter body while the prosthetic heart valve device is at least partially resheathed.

7. The system of claim 5 , wherein the delivery capsule further comprises a containment chamber configured to contain the prosthetic heart valve device, and wherein the containment chamber is fluidically sealed from the deployment chamber via the platform.

8. The system of claim 5 , wherein the expandable member is a balloon.

9. The system of claim 5 , wherein the first and second valves are three-way valves.

10. The system of claim 5 , wherein the manifold is configured to be external to the patient during an implantation procedure.

11. The system of claim 5 , wherein the first fluid lumen is fluidly isolated from the second fluid lumen.
