Abstract
A delivery device includes a handle, a central elongate member extending from the handle, a sheath configured to slide over and relative to the central elongate member, a distal tether retainer at a distal end of the central elongate member, a proximal tether restraining mechanism positioned along the central elongate member distal of the handle and proximal of the distal tether retainer, and a plurality of tethers. The tethers are configured to extend from the proximal tether restraining mechanism to the distal tether retainer.
Claims20
A method of delivering a prosthetic mitral valve into the heart of a patient, the method comprising:
- extending a delivery device into the heart with the prosthetic mitral valve collapsed within an outer sheath of the delivery device;
- sliding the outer sheath to expose at least a first anchor of the prosthetic mitral valve;
- loosening a plurality of tethers of the delivery device that are coupled to the first anchor to allow the first anchor to self-expand to an expanded annular configuration on a first side of the mitral valve annulus;
- and
- allowing a second anchor of the prosthetic mitral valve to self-expand on a second side of the mitral valve annulus, the expansion of the first anchor and the second anchor causing the first anchor and the second anchor to move towards each other and capture tissue of the mitral valve annulus between the first anchor and the second anchor.
