Methods and apparatuses for deploying minimally-invasive heart valves
First Claim
1. A medical assembly for replacing a native heart valve of a patient, the assembly comprising:
- a radially expandable and collapsible prosthetic heart valve comprising a self-expandable stent body and a plurality of leaflet-forming membranes, the stent body having a proximal end and a distal end;
a deployment mechanism configured to deploy the prosthetic heart valve within the native heart valve of the patient, the prosthetic heart valve being coupled to the deployment mechanism; and
a storage container;
wherein the prosthetic heart valve and the deployment mechanism are disposed in the storage container with the prosthetic heart valve in a radially expanded configuration, and the prosthetic heart valve is compressible from the radially expanded configuration to a radially contracted configuration with the deployment mechanism coupled to the prosthetic heart valve;
wherein the prosthetic heart valve comprises a mechanical locking device configured to lock the prosthetic heart valve in a final expanded configuration inside the patient.

Abstract
A medical assembly for replacing a native heart valve of a patient. The medical assembly includes a radially expandable and collapsible prosthetic heart valve having a self-expandable stent body and a plurality of leaflet-forming membranes. The medical assembly also includes a deployment mechanism configured to deploy the prosthetic heart valve within the native heart valve of the patient. The deployment mechanism preferably includes a plurality of proximal deployment members coupled to a proximal end of the stent body. The deployment mechanism may also include a plurality of distal deployment members coupled to a distal end of the stent body. The prosthetic heart valve desirably includes a mechanical locking device configured to lock the prosthetic heart valve in a radially expanded configuration.

13. A medical assembly for replacing a native heart valve of a patient, the assembly comprising:
-
a radially expandable and collapsible prosthetic heart valve comprising a self-expandable stent body and a plurality of leaflet-forming membranes, the stent body having a proximal end, a distal end and a mechanical locking device configured to lock the prosthetic heart valve in a final expanded configuration inside the patient; and a deployment mechanism configured to deploy the prosthetic heart valve within the native heart valve of the patient, the prosthetic heart valve being coupled to the deployment mechanism; wherein the deployment mechanism is configured to radially expand for permitting the prosthetic heart valve to self-expand from a radially contracted configuration to an initial radially expanded configuration while still coupled to the prosthetic heart valve and when actuated, the deployment mechanism causes the prosthetic heart valve to further expand from the initial expanded configuration to the final expanded configuration, wherein the mechanical locking device is configured to lock the prosthetic heart valve when it reaches the final expanded configuration. - View Dependent Claims (14, 15, 16, 17)
