Abstract
In general, in an aspect, an annulus of a heart valve is caused to dilate to a predetermined configuration by pushing a delivery tool distally through the annulus from one heart chamber to another heart chamber. A valve support is attached to the delivery tool. The valve support has a plurality of barbs or hooks attached thereon. While the annulus is dilated, the valve support is attached to tissue at locations along the annulus by attaching the barbs or hooks to the tissue. After attachment, the support is caused to contract.
