Abstract
The ventricle of a heart can be reshaped by passing a plurality of catheters from inside the ventricle to outside the ventricle through holes in the ventricle wall. Fluid-tight bags are then delivered through the catheters and expanded outside the ventricle to a diameter that is larger than the holes. A fluid substance is introduced into the bags, and the fluid substance is configured to solidify into solid pads that are also larger than the holes. The solid pads are then pulled towards each other and locked in position in order to reshape the ventricle.
Claims20
An apparatus for reshaping a ventricle of a heart, the ventricle having a first wall section and a second wall section that is disposed opposite to the first wall section, the apparatus comprising:
- a first fluid-tight bag having a first inlet that is configured to accept a fluid and a distal end that is configured to pass through a first hole in the first wall section and extend outside the ventricle, wherein the first fluid-tight bag is configured so that when the distal end has passed through the first hole and has been extended outside the ventricle, at least a portion of the distal end that extends outside the ventricle has a diameter that is larger than the first hole;
- a first solid filler material disposed outside the ventricle in the distal end of the first fluid tight bag, the first solid filler material having diameter that is larger than the first hole, wherein the first solid filler material is formed by introducing at least one fluid substance into the first fluid tight bag via the first inlet after the distal end of the first fluid tight bag has passed through the first hole and has been extended outside the ventricle, wherein the at least one fluid substance is configured to solidify after being introduced into the first fluid tight bag;
- a second fluid-tight bag having a second inlet that is configured to accept a fluid and a distal end that is configured to pass through a second hole in the second wall section and extend outside the ventricle, wherein the second fluid-tight bag is configured so that when the distal end has passed through the second hole and has been extended outside the ventricle, at least a portion of the distal end that extends outside the ventricle has a diameter that is larger than the second hole;
- a second solid filler material disposed outside the ventricle in the distal end of the second fluid tight bag, the second solid filler material having a diameter that is larger than the second hole, wherein the second solid filler material is formed by introducing at least one fluid substance into the second fluid tight bag via the second inlet after the distal end of the second fluid tight bag has passed through the second hole and has been extended outside the ventricle, wherein the at least one fluid substance is configured to solidify after being introduced into the second fluid tight bag;
- and
- an elongated member having a first end and a second end, wherein the first end of the elongated member is attached to the first solid filler material and the second end of the elongated member is attached to the second solid filler material, and wherein the elongated member is configured to pull the first solid filler material towards the second solid filler material.
