Abstract
A heart valve annulus repair device having a tissue engaging member and a plurality of anchors. The tissue engaging member includes a loop of wire. Each of the anchors has a pointy front end and a back end and a slot that runs in a front-to-back direction. The anchors are distributed about the loop of wire with the front ends of the plurality of anchors facing the heart valve annulus and with the loop of wire passing through the slots. The device further includes means for implanting the anchors into the heart valve annulus tissue so that the tissue engaging member becomes affixed to the heart valve annulus.
Claims16
A method for replacing a native cardiac valve located between a ventricle and an atrium, the native valve having leaflets, the method comprising:
- attaching a loop of material to the leaflets of the native valve so that the loop of material is suspended from the leaflets of the native valve within the ventricle;
- after the loop of material is attached to the leaflets of the native valve, advancing a prosthetic valve through a delivery catheter;
- and
- after the prosthetic valve has been advanced through the delivery catheter, expanding the prosthetic valve into the loop of material so that an interaction between the loop of material, the leaflets of the native valve, and the prosthetic valve secures the prosthetic valve in place at an operative position between the ventricle and the atrium.
An apparatus for replacing a native cardiac valve located between a ventricle and an atrium, the native cardiac valve having leaflets, the apparatus comprising:
- a loop of material configured for affixation to the leaflets such that the loop of material is positioned within the ventricle and suspended from the leaflets of the native valve;
- and
- a prosthetic valve configured to move between a collapsed state and an expanded state,
- wherein the loop of material and the prosthetic valve are configured so that after the loop of material is affixed to the leaflets such that the loop of material is positioned within the ventricle and suspended from the leaflets of the native valve, and the prosthetic valve is subsequently expanded within the loop of material from the collapsed state to the expanded state, an interaction between the loop of material, the leaflets of the native valve, and the prosthetic valve secures the prosthetic valve in place at an operative position between the ventricle and the atrium.
