A tissue gripping device is formed from a shape-memory material, and has a base section, a first arm, and a second arm disposed opposite the first arm, each arm having a first end coupled to the base section and a free end extending from the base section. The arms of the tissue gripping device are configured to resiliently flex toward a relaxed configuration in a distal direction as the tissue gripping device is moved from a pre-deployed configuration toward a deployed configuration. The tissue gripping device is usable in a method for gripping tissue. The method includes positioning the tissue gripping device near target tissue and moving the tissue gripping device from a pre-deployed configuration toward a deployed configuration in order to grip the target tissue.

Tissue grasping devices and related methods

An intravascular device includes a shaft having a body defining a major lumen and a plurality of minor lumen. The minor lumens are spaced about the major lumen. The major lumen and the plurality of minor lumen extend from a proximal end of the body to a distal end of the body. One or more wires may extend through the major lumen and/or minor lumen.

Delivery catheter systems, methods, and devices

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.
