Abstract
An actuator sleeve includes resiliency features that may reduce chronic strain on valve annulus implants. The resiliency features may relate to one or more of a material, a manufacture, a dimension, and/or design attribute of the sleeve. In one aspect the resiliency features may allow deformation of the sleeve at frame interfaces to distribute forces to reduce the frame fatigue.
