Abstract
A system for minimally invasive insertion of a bioprosthetic heart valve. The system includes a collapsible tissue-based valve system, a catheter-based valve delivery system, a surgical platform and a device tracking and visualization system. The collapsible valve system includes: (i) a permanent outer frame ( ) that is affixed to the patient using conventional sutures or staples, and (ii) a collapsible valve ( ) having a collapsible inner frame ( ) that mates with the outer frame ( ), and supports valve leaflets ( ). The inner frame ( ) is moved to a collapsed position and located at the previously installed outer frame ( ). The inner frame ( ) is then expanded to lock the inner frame ( ) to the outer frame ( ). The inner frame ( ) may be re-collapsed and disengaged from the outer frame ( ). A new collapsible valve ( ) is then installed, to resume the function of the prosthesis.
