Apparatus, system, and method for applying and adjusting a tensioning element to a hollow body organ
An adjustable support pad for adjustably holding a tensioning line used to apply tension to a body organ. The adjustable support pad can include a locking mechanism for preventing slidable movement of the tensioning element in one or both directions. The locking mechanism may include spring-loaded locks, rotatable cam-like structures, and/or rotatable spool structures. The adjustable support pad may be formed from rigid, semi-rigid, and/or flexible materials, and may be formed to conform to the outer surface of a body organ. The adjustable support pad can be configured to adjustably hold one or more separate tensioning lines, and to provide for independent adjustment of one or more tensioning lines or groups thereof.
1. A method of replacing chordae tendineae in a heart, comprising:
securing a first portion of a first replacement chordae tendon to a first heart valve leaflet;
securing a first adjustable support pad to the heart, wherein the first adjustable support pad includes a locking mechanism configured to slidingly receive the first replacement chordae tendon in a first direction with respect to the first adjustable support pad, and to prevent the first replacement chordae tendon from sliding in a second direction with respect to the first adjustable support pad, wherein the first direction is opposite to the second direction;
slidingly securing a second portion of the first replacement chordae tendon to the first adjustable support pad; and
adjusting tension in the first replacement chordae tendon by slidingly moving the first replacement chordae tendon in a first direction with respect to the adjustable support pad.
2. The method of claim 1 , wherein the adjustable support pad comprises compressible material, and further comprising:
creating a hole in the compressible material using a suturing needle; and
passing the first replacement chordae tendon through the compressible material using the suturing needle.
3. The method of claim 1 , comprising:
monitoring the function of the heart valve while the heart is beating.
4. The method of claim 3 , wherein adjusting the tension in the first replacement chordae tendon happens concurrently with monitoring the function of the heart valve.
5. The method of claim 3 , wherein monitoring the function of the heart valve comprises monitoring via echocardiography.
