Abstract
Systems and methods for percutaneous, transcatheter heart valve repair are disclosed. A system may include a catheter, an adjustable ring, and a stabilizer. The adjustable ring may include a body member that is transitionable from an insertion geometry to an operable geometry. The insertion geometry may be configured to allow percutaneous passage of the ring into the heart. The operable geometry may have an expanded state to conform to an annulus of a target valve and a contracted state to reduce a diameter of the annulus. The adjustable ring may also include a plurality of anchors deployable in the operable geometry to engage the annulus. The stabilizer may include a plurality of prongs configured to engage the ring in the operable geometry within the heart to enable percutaneous manipulation of the ring to orient and position the ring in intimate contact with the annulus.
