Abstract
The present disclosure provides methods of improving cardiac function, including delivering a band to a ventricle of a heart via at least one catheter; guiding the band through the heart to form a loop; pulling walls of the ventricle of the heart inwards by tightening the band following formation of the loop; following tightening, locking the band in the loop; and removing the at least one catheter from the heart.
Claims21
1-20. (canceled)
A method of improving cardiac function, the method comprising:
- delivering a band to a ventricle of a heart via at least one catheter;
- guiding the band through the heart to form a loop;
- pulling walls of the ventricle of the heart inwards by tightening the band following formation of the loop;
- following tightening, locking the band in the loop;
- and
- removing the at least one catheter from the heart.
The method of claim 1, wherein tightening the band to pull the walls of the ventricle inward causes papillary muscles to move closer together.
The method of claim 1, wherein the band is in a form of a tube, and wherein delivering the band includes passing the band over a guidewire.
The method of claim 1, wherein the band is hollow, and wherein delivering the band includes passing the band over a guidewire.
The method of claim 4, wherein the guidewire is steerable.
The method of claim 1, wherein a circumference of the loop after tightening the band is smaller than the circumference of the loop before tightening the band.
The method of claim 1, wherein at least a portion of the band does not include a hollow tube.
The method of claim 1, wherein the band is manufactured by braiding.
The method of claim 1, wherein delivering the band to the ventricle occurs transvenously.
The method of claim 1, performed in a left ventricle of the heart.
The method of claim 1, wherein the band is self-locking.
The method of claim 1, wherein tightening the band to pull the walls of the ventricle inward includes tightening the band until the loop reaches a desired size.
The method of claim 1, wherein locking the band in the loop is accomplished with a suture lock.
A method of improving cardiac function, the method comprising:
- delivering a tube to a ventricle of a heart via at least one catheter;
- guiding the tube through the heart to form a loop;
- pulling walls of the ventricle of the heart inwards by tightening the tube following formation of the loop;
- following tightening, locking the tube in a looped configuration;
- and
- removing the at least one catheter from the heart.
