Abstract
A device for percutaneously deploying a stented prosthetic heart valve includes a distal portion, a spacing collar, and an outer collar. The distal portion provides a coupling structure configured to selectively engage the stented prosthetic heart valve. The spacing collar is located proximal to the distal portion. The spacing collar is transitionable from a loaded state to an activated state. The spacing collar in the loaded state has a radial dimension less than the spacing collar in the activated state. The outer collar is configured to be movable relative to the distal portion and the spacing collar. The outer collar is slidably disposed over the spacing collar to provide the loaded state and is slidably retracted from the spacing collar when in the activated state.
