Cardiac prosthesis delivery device having device position feedback

A delivery device for delivering a cardiac prosthesis to a target site, the delivery device comprising:

• a sheath;
• a shaft at least partially positioned coaxially within the sheath;
• a handle connected to the sheath and the shaft, the handle including:
• a body having an inner surface,
• an actuator connected to the body and configured to control linear movement of the sheath relative to the shaft, the handle further including a feedback system having:
• at least one ridge, and
• a clip including a first flap extending from the sheath;
• the first flap being configured to contact and travel over the at least one ridge when the sheath moves longitudinally;
• wherein the feedback system is configured to convey a first feedback indication when the first flap contacts and travels past the at least one ridge;
• further wherein the first feedback indication is selected from the group consisting of audible feedback, tactile feedback and a combination thereof that specifies a position of the sheath with respect to the shaft.
