Valve delivery tool

A prosthetic valve delivery device comprising:

• a handle coupled to a rotary shaft;
• a grasping member coupled to the rotary shaft, the grasping member defining a recess within which a prosthetic valve is configured to be received, the rotary shaft configured to rotate in a first direction, such that a diameter of the recess defined by the grasping member decreases to radially compress the prosthetic valve, and in a second direction, such that the diameter of the recess defined by the grasping member increases to allow the prosthetic valve to radially expand;
• and
• a stationary shaft coupled to the handle,
• wherein the grasping member comprises one or more coil arms, wherein the one or more coil arms are attached to the rotary shaft and define the recess within which the prosthetic valve is configured to be received, and wherein rotation of the rotary shaft in the first direction twists the one or more coil arms about the stationary shaft to reduce the diameter of the recess, and wherein rotation of the rotary shaft in the second direction untwists the one or more coil arms from the stationary shaft to increase the diameter of the recess.
