Patent ID: 7500989

Claim:
A device for the treatment of mitral annulus dilatation comprising: an elongate body having dimensions as to be insertable into a coronary sinus, the elongate body including: a proximal frame having a proximal anchor, the proximal anchor being transferable between a first state and a second state; a distal frame having a distal anchor, the distal anchor being transferable between a first state and a second state; a ratcheting strip attached to the distal frame, the ratcheting strip having alternating engagement portions and openings, the ratcheting strip having a semi-cylindrical cross section; an accepting member attached to the proximal frame, the accepting member insertable into the openings of the ratcheting strip and adapted to engage the engagement portions of the ratcheting strip; and an actuating member being adapted to engage the ratcheting strip and to move the ratcheting strip relative to the proximal anchor; wherein the diameters of the proximal anchor and the distal anchor are greater in the second state than in the first state; wherein the proximal anchor is adapted to allow the ratcheting strip to be pulled through it; and wherein the distal frame further comprises a bridge of X-shaped elements, wherein the bridge is more flexible than the ratcheting strip.
