Abstract: Novel tools and techniques are provided for implementing protection of at least one tissue layer of a medical device or implant during crimping of the medical device or implant. In various embodiments, an implant tissue protection tool may include an outer portion configured to surround one or more outer segments of at least one tissue layer of a medical device to be implanted into a body of a subject and at least one protrusion (which may be affixed to a surface of the outer portion) configured to minimize or prevent occurrence (or likelihood of occurrence) of the at least one tissue layer (in some cases, leaflet material, or the like) of the medical device passing through at least one opening defined by a frame structure of the medical device during crimping of the medical device by a crimping device in preparation for implantation into the body of the subject.

Abstract: A transcatheter valve prosthesis includes a stent having a crimped configuration for delivery within a vasculature and an expanded configuration for deployment within a native heart valve. The stent includes at least one axial frame member. The transcatheter valve prosthesis includes at least one outflow marker positioned on the at least one axial frame member. The transcatheter heart valve prosthesis may include inflow markers positioned within the inflow portion of the stent. The transcatheter heart valve prosthesis may include two outflow markers disposed on axial frame members and being circumferentially and longitudinally offset from each other. The markers are configured to aid in axial and circumferential aligned of the transcatheter heart valve prosthesis within a native heart valve.
