    Abstract: Described herein are methods and apparatus for implanting grafts to leaflets for cardiac procedures that are performed minimally-invasively while the heart is beating. The graft elongates, reinforces, and patches the leaflet. In certain disclosed examples, the graft is secured to the atrium or ventricle side of the leaflet with an artificial cord implanted on an edge of the graft to improve coaptation. In some disclosed examples, the graft is secured to both leaflets to enable an edge-to-edge procedure similar to the Alfieri technique. Some examples of the disclosed methods including introducing the graft into the ventricle and guiding it into place using artificial cords previously implanted in the leaflet.

    Abstract: A method of suturing a tissue opening can comprise placing a tissue-facing surface of a first pad, a second pad and a third pad over respective tissue areas adjacent to the tissue opening. The second pad can be positioned on a first side of the first pad and the third pad can be positioned on a second side of the first pad. The first and second pads can be coupled to a suture, the suture forming a stitch over the upper surface of each of the respective pads. The suture can be stitched through an area of tissue between the first pad and the second pad, between the second pad and the third pad, and between the third pad and the first pad. A first distal portion and a second distal portion of the suture can be coupled to the third pad for forming the purse-string suture.

    Abstract: An annuloplasty ring for repair of mitral valves whose shape can be altered directly or remotely to perform post-implant size and/or shape adjustments. One version of the annuloplasty ring has a size-adjustable remodeling inner core within an outer suture-permeable interface for attaching the ring to an annulus. The inner core has a size-adjustable segment formed by short spaced-apart tubular sections that can move toward and way from one another such as on rails. Alternatively, short sections separated by compressible connectors may be used. One or more tethers may be attached to one side of the size-adjustable segment and pulled from the other side to constrict the segment. Multiple tethers may be connect at different locations around the ring to provide some control over where the ring constricts. An adjustment handle with a flexible shaft may be operated from outside the body to adjust the ring post-implant.
