Abstract:
A loader and method for loading a transcatheter heart valve into a delivery sheath or catheter is described that is also configured to facilitate retrieval of the heart valve back through the delivery sheath while protecting the delivery sheath from damage. Another loader provides for easier crimping and loading of a THV into a delivery sheath or catheter from a storage jar or container. A method for crimping a THV facilitates easier end user preparation of the valve for implantation and reduces the likelihood of tissue deformation in the valve during storage. These devices and methods for deploying THVs simplify the valve replacement procedure.
