Definitions
- FIG. 1 depicts an embodiment of the MLC device which includes a stem portion, a first tube, and a second tube;
- FIG. 16 depicts the anchor is placed on the first arm
- the first tube 20 may include the lumen 24 extending between the proximal end 22 and distal end 23.
- the first arm portion 21 of the first tube 20 is defined as a potion from the hinge portion 16 to the distal end 23.
- the first arm portion 21 may be pre-shaped with soft materials like synthetic, rubber, soft plastic, etc., or metal materials such as a coil spring, etc. such that it maintains the preformed shape when traverses through the coronary sinus.
- FIGS. 12-13 show the first arm portion 21 traversing through the coronary sinus.
- the first arm portion 21 is configured to be inserted through the coronary sinus to encircle at least part of the mitral valve. When a tension is applied, as shown FIG. 13, the first arm portion 21 is configured to tighten the annulus of the mitral valve for reducing the regurgitation.
- FIG. 4 shows the cerclage rope 50.
- the cerclage rope 50 comprises an arch portion 51 .
- the arch portion 51 is covered by an outer layer 52 as shown on FIGS. 4-5.
- the outer layer 52 is coated integrally onto the arch portion 51 .
- the outer layer may be coated longer and tapered towards the stopper 40 as shown on FIG. 8.
- the arch portion 51 and its outer layer 52 is configured to protect the coronary artery and its surrounding heart tissues as tension is applied onto the cerclage rope 50.
- the MLC device 10 may be advanced over the 2 free ends 55, 56 of the cerclage rope 50.
- FIG. 9 shows the straightened first and second arm portions 21 , 31 of the first and second tubes 20, 30 contained within the sheath.
- the straightened first and second arm portions 21, 31 of the MLC device 10 is fed over the two ends 55, 56 of the cerclage rope 50 starting with its distal ends 23, 33 of the first and second tubes 20, 30.
- the first and second arm portions 21, 31 are restored into its preformed shapes as shown in FIG. 11 .
