Abstract: Embodiments of the present disclosure include a method of transcatheterly delivering a band to encircle multiple papillary muscles in a heart. The method may comprise transcutaneously inserting a catheter into a heart and delivering a first end of a first guidewire to a ventricle in the heart via the catheter. The method may further comprise looping a first end of a first guidewire around a first papillary muscle and a second end of a second guidewire around a second papillary muscle. The first end of the first guidewire and the second end of the second guidewire may be brought out of the body while the first and second guidewires remain looped around the first and second papillary muscles, respectively. The first and second guidewires may be interconnected, and at least one end of the first and second guidewires may be pulled to establish a single loop around the papillary muscles.

Abstract: Embodiments of the present disclosure include a device for repositioning papillary muscles. The device may comprise a band configured to encircle a cluster of papillary muscles. The cluster of papillary muscles may have an outer peripheral boundary defined by the encircling band, and the band may comprise a first end and a second end. The device may further comprise an adjustable clasp coupled to a location proximate the first end of the band. The clasp may be configured to transition from an open configuration to a closed configuration to connect the second end of the band to the first end of the band, thereby forming a loop. The clasp may be selectively actuatable to adjust a length of the loop.
