Abstract
A delivery catheter for a prosthetic heart valve, the valve expandable from a collapsed condition for delivery to an ex paneled condition for implantation, the delivery catheter comprising: a holder for engaging the valve in the collapsed state of the valve, the holder configured such that (i) in response to a radial compression force exerted thereon, the holder has a first shape defining an exposed engagement region for engaging at least a portion of the collapsed prosthetic heart valve for restraining axial displacement of the prosthetic valve in at least one axial direction of the catheter, and (ii) in response to removal of the radial compression force upon expansion of the valve, at least a portion of the holder transitions to a second shape.
