Apparatus and method for elongation of a papillary muscle
First Claim
1. A system for treating a dilated heart valve comprising:
- a delivery device 100 comprising a delivery catheter 110 and a holding catheter 130;
a muscle elongation device 200 coupled to the holding catheter 130 and received in the delivery catheter 110, the muscle elongation device 200 including at least one clamping device 215 and disposed adjacent a distal end 116 of the holding catheter 110, the at least one clamping device 215 slidably disposed on an at least one connecting rod 220, wherein when the system is delivered to a muscle region associated with the dilated heart valve, the muscle elongation device 200 is released from the delivery catheter 110 and the at least one clamping device 215 wraps around the muscle region.

Abstract
A system and method for treating a dilated heart valve by elongating a papillary muscle. The system comprises a delivery catheter 110 and a holding catheter 130. The system further comprises a muscle elongation device 200 including at least two clamping rings 210, 215 slidably connected by at least one connecting rod 220. The muscle elongation device 200 is delivered to a papillary muscle 560 associated with the dilated heart valve, where it is released from the delivery catheter 110 and the clamping rings 210, 215 wrap about and engage the papillary muscle. The muscle tissue is cut between the clamping rings 210, 215, which then move away from each other to a predetermined position, thus permitting the papillary muscle to elongate.

15. A muscle elongation device 200 for treatment of a dilated heart valve, comprising:
-
at least one connecting rod 220;
a first clamping device 210 fixed to the at least one connecting rod; and
a second clamping device 215 slidably disposed along the connecting rod, wherein the first clamping device 210 and the second clamping device 215 have a first diameter in a delivery configuration and a second diameter in a clamping configuration, the second diameter less than the first diameter. - View Dependent Claims (16, 17, 18, 19, 20)

21. A method for treating a dilated heart valve, the method comprising:
-
delivering a muscle elongation device 200 in a lumen of a delivery catheter 110 proximate a dilated heart valve;
positioning at least two clamping devices 210, 215 disposed along at least one connecting rod 220 of the muscle elongation device 200 on a muscle region 560 proximate the dilated heart valve;
releasing the muscle elongation device 200 from the delivery catheter 110;
wrapping the clamping devices 210, 215 about the muscle region 560;
cutting the muscle between the clamping devices 210, 215; and
sliding the clamping devices 210, 215 away from each other along the connecting rod. - View Dependent Claims (22)
