System and method for transcatheter heart valve platform
First Claim
1. A system for delivering a platform to support a prosthetic mitral valve in a patient'"'"'s heart, the system comprising:
- a delivery catheter that includes a slidable sheath;
a tube positioned within the slidable sheath defining a structure that includes;
an annular portion defining a bore and an axis that extends along the bore, and further defining at least one opening in a circumferential surface of the annular portion,a plurality of upper elements attached to an upper perimeter of the annular portion and extending axially, anda plurality of lower elements attached to a lower perimeter of the annular portion and extending axially; and
a piston configured to slide within the tube, the piston defining a lumen that receives at least one pin configured to slide out of the lumen so as to pass through the at least one opening; and
wherein the slidable sheath includes a resilient ring at a distal end of the slidable sheath.

Abstract
A method for delivering a platform for reinforcing an annulus of a mitral valve: Passing a catheter having a sheath covering a tube formed from a metal into the left atrium, the tube including: an annular portion defining at least one opening, a plurality of upper elements attached to an upper perimeter of the annular portion and extending axially, and a plurality of lower elements attached to a lower perimeter of the annular portion. Inserting the tube into the annulus of the mitral valve; withdrawing the sheath, but leaving the sheath covering the annular portion and the upper elements; bending the lower elements until the lower elements extend radially so as to be positioned beneath the mitral valve; then withdrawing the sheath from covering the annular portion and the upper elements; bending the upper elements until the upper elements extend radially so as to be positioned above the mitral valve.

9. A method for delivering a platform for reinforcing an annulus of a mitral valve in a heart of a patient, the heart including a right atrium, a left atrium, and a septum separating the right atrium from the left atrium, the method comprising:
-
providing a delivery system having; a delivery catheter that includes a slidable sheath, a tube positioned within the slidable sheath defining a structure that includes; an annular portion defining a bore and an axis that extends along the bore, and further defining at least one opening in a circumferential surface of the annular portion, a plurality of upper elements attached to an upper perimeter of the annular portion and extending axially, and a plurality of lower elements attached to a lower perimeter of the annular portion and extending axially, and a piston configured to slide within the tube, the piston defining a lumen that receives at least one pin configured to slide out of the lumen so as to pass through the at least one opening, wherein the slidable sheath includes a resilient ring at a distal end of the slidable sheath; passing, via a femoral artery of a patient, the catheter into the right atrium, then through the septum into the left atrium, withdrawing the sheath from covering the plurality lower elements, but leaving the sheath covering the annular portion and the plurality of upper elements; bending the plurality of lower elements by imparting a plastic deformation to the metal until the plurality of lower elements extend radially so as to be positioned beneath the mitral valve; then withdrawing the sheath from covering the annular portion and the plurality of upper elements; and bending the plurality of upper elements by imparting a plastic deformation to the metal until each of the plurality of upper elements extends radially so as to be positioned above the mitral valve. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
