Abstract
A mitral cerclage annuloplasty apparatus comprises a tissue protective device and a knot delivery device. The tissue protective device comprises a first protective tube and a second protective tube. The knot delivery device comprises a tube wherein a loose knot is looped around its distal end through a hole and wherein tight knot is formed when the distal end of the tube is cut open. Alternatively, the knot delivery device comprises an inner tube and outer tube. The inner tube is insertable and rotatable inside the outer tube. When the tubes are in a closed position by rotating either the outer tube or the inner tube, a hole is created near its distal end. When the tubes are in open position by rotating either the outer tube or the inner tube, the hole joins the opening of the outer tube and lengthens.
Claims8
A set of devices for mitral valve annuloplasty, comprising:
- a tissue protective device, the protective device having a cerclage suture disposed within a first protective tube and a second protective tube, the first protective tube and the second protective tube each having a proximal portion and a distal portion, the proximal portions of the two protective tubes being attached side-by-side longitudinally along the length of the two protective tubes, the distal portions of the two protective tubes being separated thereafter, and a knot delivery device comprising a delivery tube having a proximal end, a hole, and distal end, wherein the ends of the cerclage suture pass through the hole to form a loose knot that is looped around the distal end of the delivery tube and wherein a tight knot is formed when the distal end of the tube is cut open.
