A prosthetic heart valve for the treatment of structural heart disease wherein the prosthetic heart valve includes an expandable frame that is formed of a rhenium containing metal alloy. The novel geometry of the expandable frame in combination with the frame being partially or fully formed of the rhenium containing alloy enables the formation of a frame that a) has an open cell geometry in the frame of the prosthetic heart valve that can be used to reduce delivery system size, b) has high radial strength, c) has improved restoration of the physiologic EOA, d) has lower recoil, e) has little or no longitudinal foreshortening, f) allows for proper placement of the bioprosthetic valve in relation to the native commissures of the valve, h) has symmetrical and cylindrical expansion of the prosthetic valve resulting in lower rates of leaflet thrombosis and structural valve deterioration, and i) prevents allergic response and restenosis associated with nickel content.

Disclosed herein is a surgical instrument configured for attachment to a surgical device. The surgical instrument includes a distal region having a curved internal surface configured to mate with a curved external surface of the surgical device, a rotational locking feature that limits rotational movement of the instrument with respect to the surgical device, and an axial locking feature that limits axial movement of the blade with respect to the surgical device. Methods of using the surgical instruments include sliding the axial locking feature past a corresponding axial locking feature on the surgical device, locking the axial locking feature to the corresponding axial locking feature on the surgical device (thereby limiting axial movement of the elongated blade with respect to the surgical device), adjusting the position of the surgical device using the surgical instrument, and disengaging the axial locking feature (for example, by using a disengagement instrument).
