Abstract
A minimally invasive device and method for suturing papillary muscles includes drawing a suture through a first papillary muscle using a needle, drawing the suture through a second papillary muscle, and tightening the suture to move at least one of the first papillary muscle and the second papillary muscle towards the other of the first papillary muscle and the second papillary muscle.
Claims9
A suturing device that can be inserted minimally invasively into the left ventricle of the heart for suturing of papillary muscles, comprising:
- a bendable catheter comprising:
- a proximal portion;
- a first opening distal to the proximal portion along a length of the bendable catheter;
- a second opening distal to the first opening along the length of the bendable catheter and configured to hold a suture loop of a suture;
- and a distal end distal to the second opening along the length of the bendable catheter;
- and
- a needle configured to extend out of the first opening and through a first side of a papillary muscle to engage the suture loop of the suture positioned on a second side of the papillary muscle;
- wherein the bendable catheter is configured to bend between a disengaged configuration and a lassoed configuration to wrap around the papillary muscle, wherein the distal end of the bendable catheter is configured to engage the proximal portion of the catheter in the lassoed configuration.
