Abstract
A minimally invasive catheter and methods are provided for adjusting the chordae associated with an atrio-ventricular valve and for modifying the geometry of selected cardiac chambers. Clamps carried by the catheter are part of a prosthetic clamp assembly that includes the clamps and a cord attached to each of the clamps. The cord length can be adjusted after the clamps are attached to tissue. The clamps can be operated simultaneously or independently.
Claims15
A catheter for selectively connecting and adjusting the position of cardiac tissues, comprising:
- an elongate catheter shaft having proximal and distal ends and a longitudinally extending axis;
- a clamp assembly comprising a pair of clamps releasably carried at the distal end of the catheter shaft, the clamps being disposed in transversely spaced relation to and on opposite sides of the axis, each clamp having distally facing portions adapted to receive a selected cardiac tissue, the clamps being closeable to securely grip selected tissue received within the clamps, each clamp being operable separately and independently of the other;
- and
- the clamp assembly having a prosthetic cord segment attached to each of the clamps.
