Abstract: The present invention provides a system and method for retaining, positioning and releasing a prosthetic heart valve. The system includes a valve holder, and a control handle. The valve holder includes a connection base and at least one holding arm. The holding arms are distributed around a periphery of the connection base, with the holding arms having positioning structures at the distal side thereof for engaging with an outflow side of the prosthetic heart valve. The control handle is coupled to the valve holder for controlling the valve holder.

Abstract: A surgical prosthetic heart valve has a supporting structure and a plurality of leaflets, the supporting structure generally having an annular shape with a blood flow channel defined in the annular shape and having opposite inflow and outflow sides along an axial direction of the annular shape, the plurality of leaflets connected to the supporting structure to control the blood flow channel to open or close. The supporting structure includes a first annular band and a second annular band, both of which are provided with deformable sections spaced from each other in the circumferential direction for allowing diameter expansion of the respective annular bands. The surgical heart valve achieves the diameter expansion of the annular bands through the deformable sections, thereby addressing the problem of postoperative variation in a valve-in-valve operations.

Abstract: A system and method having a first device mounted on a first gimbal mount; a first visual feedback associated with the first gimbal; a second device mounted on a second gimbal mount physically displaced relative to the first gimbal mount; a second visual feedback mechanism associated with the second device. The orientation of the first device differs from the orientation of the second device by a dynamic correction amount. A correction controller having input that when acted upon by a user causes movement of the second device independently of movement of the first device to alter the correction amount to a revised correction amount such that subsequent movement of the first device causes motion in the second device that is at least partially dependent upon the revised correction amount.
