Abstract
A device for repairing a heart valve includes a first clip and a second clip. The first clip comprises an inner portion and an outer portion. The inner and outer portions of the first clip are configured to compress tissue of a first heart valve leaflet therebetween to secure the first clip to the first leaflet. The second clip comprises an inner portion and an outer portion. The inner and outer portions of the second clip are configured to compress tissue of a second heart valve leaflet therebetween to secure the second clip to the second leaflet. The first and second clips are configured to be separately deployable onto the first and second leaflets and secured to one another in vivo to bring portions of the first and second leaflets into closer proximity to each other.

A device for repairing a heart valve, comprising:
- a first clip comprising an inner portion and an outer portion, wherein the inner and outer portions of the first clip are configured to compress tissue of a first heart valve leaflet therebetween to secure the first clip to the first leaflet;
- a second clip comprising an inner portion and an outer portion, wherein the inner and outer portions of the second clip are configured to compress tissue of a second heart valve leaflet therebetween to secure the second clip to the second leaflet;
- and
- wherein the first and second clips are configured to be separately deployable onto the first and second leaflets and secured to one another in vivo to bring portions of the first and second leaflets into closer proximity to each other.
A system for repairing a heart valve, comprising:
- an elongate delivery catheter comprising at least one lumen;
- a heart valve repair device coupled to the elongate delivery catheter, the heart valve repair device comprising:
- a first clip comprising an inner portion and an outer portion, wherein the inner and outer portions are configured to compress tissue of a first heart valve leaflet therebetween to secure the first clip to the first leaflet;
- a second clip comprising an inner portion and an outer portion, wherein the inner and outer portions are configured to compress tissue of a second heart valve leaflet therebetween to secure the second clip to the second leaflet;
- and
- wherein the first and second clips are configured to be separately deployable onto the first and second leaflets and secured to one another in vivo to bring portions of the first and second leaflets into closer proximity to each other.
A method of repairing a heart valve, comprising:
- opening a first clip by moving an outer portion of the first clip and an inner portion of the first clip relatively apart;
- positioning the first clip to place a first heart valve leaflet of the heart valve between inner and outer portions of the first clip;
- closing the first clip such that the inner and outer portions of the first clip compress tissue of the first heart valve leaflet therebetween to secure the first clip to the first leaflet;
- opening a second clip by moving an outer portion of the second clip and an inner portion of the second clip relatively apart while the second clip is disconnected from the first clip;
- positioning the second clip to place a second heart valve leaflet of the heart valve between inner and outer portions of the second clip while the second clip is disconnected from the first clip;
- closing the second clip such that the inner and outer portions of the second clip compress tissue of the second heart valve leaflet therebetween to secure the second clip to the second leaflet;
- and
- securing the first clip and the second clip to one another in vivo to bring portions of the first and second leaflets into closer proximity to each other.
