Abstract

The present disclosure provides methods of improving cardiac function, including transcutaneously inserting at least one catheter into a heart, delivering a band to a ventricle of the heart via the at least one catheter, guiding the band through a plurality of spaces among a trabeculae in the ventricle, tightening the band in a single loop, locking the band in a loop, and removing the at least one catheter from the heart.

Claims (21)

1 . A device for transcatheterly delivering a band through a plurality of spaces among trabeculae of a ventricle in a heart of a body, the device comprising:

at least one catheter configured for insertion into a ventricle of a heart;

at least one guidewire configured to pass through the at least one catheter and to exit the at least one catheter through an opening in a first portion of the at least one catheter, loop through the plurality of spaces among the trabeculae of the ventricle, and advance to a second portion of the at least one catheter;

a guidewire catching mechanism configured to capture the at least one guidewire near the second portion of the at least one catheter;

a band configured to tighten and lock into a single loop to pull one or more walls of the ventricle of the heart inwards, wherein the at least one guidewire is configured to guide the band through the plurality of spaces among the trabeculae of the ventricle; and

at least one pull-string configured to tighten the band to pull the one or more walls of the ventricle of the heart inward.

2 . The device of claim 1 , wherein the at least one pull-string is a self-locking pull-string.

3 . A device for transcatheterly delivering a band through a plurality of spaces among trabeculae of a ventricle in a heart of a body, the device comprising:

at least one catheter configured for insertion into a ventricle of a heart;

at least one guidewire configured to pass through the at least one catheter and to exit the at least one catheter through an opening in a first portion of the at least one catheter, loop through the plurality of spaces among the trabeculae of the ventricle, and advance to a second portion of the at least one catheter;

a guidewire catching mechanism configured to capture the at least one guidewire near the second portion of the at least one catheter;

a band configured to tighten and lock into a single loop to pull one or more walls of the ventricle of the heart inwards, wherein the at least one guidewire is configured to guide the band through the plurality of spaces among the trabeculae of the ventricle; and

a locking mechanism including a plurality of beads and configured to permit the plurality of beads to pass therethrough in first direction, and to prevent the plurality of beads from passing therethrough in a second direction, opposite the first direction.

4 . A device for transcatheterly delivering a band through a plurality of spaces among trabeculae of a ventricle in a heart of a body, the device comprising:

at least one catheter configured for insertion into a ventricle of a heart;

at least one guidewire configured to pass through the at least one catheter and to exit the at least one catheter through an opening in a first portion of the at least one catheter, loop through the plurality of spaces among the trabeculae of the ventricle, and advance to a second portion of the at least one catheter;

a guidewire catching mechanism configured to capture the at least one guidewire near the second portion of the at least one catheter; and

a band configured to tighten and lock into a single loop to pull one or more walls of the ventricle of the heart inwards, wherein the at least one guidewire is configured to guide the band through the plurality of spaces among the trabeculae of the ventricle,

wherein the at least one guidewire includes a first guidewire and a second guidewire, and

wherein the device further comprises a connector configured to interconnect a first end of the first guidewire with a second end of the second guidewire.

5 . The device of claim 4 , wherein the connector includes at least one of a flexible connector, a rigid connector, or a knot.
