Abstract: A crimper includes atop iris shell defining atop iris channel. The crimper also includes abase iris shell coupled to the top iris shell at a pivot connection, the base iris shell defining a base iris channel. The top iris shell is configured to rotate about the pivot connection relative to the base shell from an open state to a closed state. When in the open state, the base iris channel is exposed for loading the expandable medical device. When in the closed state, the top iris channel and the base iris channel define a crimper chamber. The crimper also includes a handle configured to operate the clamshell crimper. The actuation of the handle decreases a volume of the crimper chamber to transition the expandable medical device from the uncompressed state to the compressed state.

Abstract: A crimper configured to radially compress a transcatheter valve prosthesis into a crimped configuration for delivery within a vasculature. The transcatheter valve prosthesis includes a frame and at least one leaflet secured within the frame. The crimper is configured to apply pressurized fluid to the at least one leaflet of the transcatheter valve prosthesis during the crimping process to prevent protrusion of the leaflet into the frame of the transcatheter valve prosthesis that may cause leaflet pinching and damage. The crimper includes a plurality of crimper elements that collectively define a crimper chamber of the crimper, and at least one crimper element of the plurality of crimper elements includes an integral channel extending therethrough for applying the pressurized fluid to the at least one leaflet.

Abstract: A catheter includes a handle with torqueing and steering mechanisms. The torqueing mechanism includes a rotatable nosecone and a bearing coupled to the nosecone to be rotatable therewith. The bearing is concentrically disposed over a shaft of the catheter. The steering mechanism includes a rack coupled to the bearing to be slideable therewith and a pull wire having a proximal end attached to the bearing and a distal end attached to a distal portion of the shaft. Rotation of the nosecone causes an entire length of the shaft to rotate and axial movement of the rack tensions the pull wire to bend the distal portion of the shaft. A valve relief component is slidingly disposed over the shaft and is configured to dock onto the handle when not in use.
