Self-expandable heart valve prosthesis collapsing tool base
Definition
A plate-like device designed to function as a sturdy support (base) for a self-expanding cardiac valve prosthesis collapsing tool during the procedure where the tool is used to reduce the diameter of a self-expanding cardiac valve prosthesis to facilitate its implantation. It typically consists of a stainless steel plate-like base with holes and slots for attachment of the collapsing tool, and supports for alignment of the valve holder. This is a reusable device intended to be sterilized prior to use.
