Abstract: Valve delivery catheter assemblies including components that limit trauma to the expanded prosthetic valve and body channels as the distal tip of the catheter is withdrawn through the expanded valve and thereafter from the body. In one embodiment, a catheter assembly according to the present invention includes a handle assembly, an introducer sheath, and a distal tip assembly. The handle assembly cap include a fixed main handle and two or more rotating handles that allow a user to control the distal tip assembly of the catheter. A valve retaining mechanism ears be included to assist in retaining the prosthetic valve prior to deployment. Each control knob on the handle assembly controls a portion of the components on the distal tip of the catheter by allowing for precise manipulation of various delivery shafts. Each delivery shaft extends from the handle assembly to respective positions towards the distal end of the catheter.

Abstract: The medical devices and methods disclosed herein can be used to close a transapical entry point after a medical procedure, or various other anatomical apertures. The medical devices can include a first disc and a second disc, which can be compressed within a catheter, having a distal surface and a proximal surface. A shaft can be attached to, and extend from, the first disc. The second disc can have a hole sized such that the shaft can fit through the hole. In certain embodiments, the proximal surface of the first disc and the distal surface of the second disc can include a plurality of tissue engagement elements, such as teeth. In certain embodiments, the shaft can include a plurality of locking notches such that the second disc can be advanced only in the distal direction over the locking notches.
