Strangling the heart valve annulus and placing the ring on the heart valve annulus

摘要

The heart annulus can be strangulated by delivering the cord to the annulus, securing the cord, and then using a device to tighten the cord. In some embodiments, the apparatus comprises an elongated inner core having a main channel, a first set of channels, and at least one second channel, wherein the main channel, the first set of channels, and at least Any one second channel extends through the inner core. The first channel contains a pull wire for starting the anchor driver and the second channel contains multiple portions of the cord. A support arm extends distally beyond the inner core and an anchor driver is attached to each of these support arms. The support arm holds the distal end of the anchor driver in a distributed position along the annulus. The anchor is driven to secure the cord and the cord is tightened in a later procedure.
