摘要：
Methods and systems for delivering and deploying a prosthetic heart valve include a deployment mechanism coupled to the prosthetic heart valve, the deployment mechanism having a longitudinal shaft that when rotated in a first direction, expands the prosthetic heart valve from a contracted state to an expanded state, and optionally, when rotated in a second direction opposite the first direction, re-contracts the prosthetic valve from the expanded state. Embodiments of the deployment mechanism include a pinion gear that engages a gear track on the prosthetic heart valve.
