a main knob assembly configured to advance and retract a multilumen shaft assembly, wherein the multilumen shaft assembly comprises a multilumen shaft configured to connect to the implant on a distal end and to an actuation mechanism on a proximal end;

a stabilizing tool comprising a plurality of prongs configured to engage the implant within the heart to make an intimate contact with the heart tissue using a stabilizer and a tongue assembly, wherein the stabilizing tool is configured to be controlled by a multilumen cart, wherein the multilumen cart is configured to enable sealing and flushing of the multilumen shaft; and

a back assembly comprising:

the actuation mechanism;

a suture routing mechanism;

a tip lock mechanism; and

a back cover configured to protect all sutures being cut by mistake.

2. The delivery system of claim 1 , wherein the steerable sheath comprises a rigid element braided with a specifically patterned metal wire.

3. The delivery system of claim 1 , wherein the steerable sheath comprises a wire coiled around the steerable sheath.

4. The delivery system of claim 1 , wherein the steerable sheath comprises a hypotube on an outer surface of the sheath.

5. The delivery system of claim 1 , wherein the steerable sheath comprises a heat shrink and a pull ring.

6. The delivery system of claim 1 , wherein the steerable sheath is connected to a multilumen base comprising a flushing port configured to be attached to a hemostat.

7. The delivery system of claim 1 , wherein the steerable sheath has a sheer strength of about 1,000 newtons (N).

8. The delivery system of claim 1 , wherein the multilumen shaft comprises a multilumen extrusion, a metallic backbone, an interface assembly, the stabilizer, the tongue assembly, and the stabilizing tool.

9. The delivery system of claim 1 , wherein the steering shaft comprises a plurality of flat surfaces, wherein a distance between adjacent flat surfaces is in a range from about 30 mm to about 150 mm.

10. The delivery system of claim 1 , wherein the steering shaft comprises a flat surface configured to determine a steering stroke and a steering direction.

11. The delivery system of claim 1 , wherein the stabilizing tool comprises a flexible segment configured to steer the multilumen shaft.

12. The delivery system of claim 1 , wherein the ball joint mechanism comprises:

a handle; and

a ball joint plate comprising a conical surface.

13. The delivery system of claim 1 , wherein the main knob assembly is in a normally closed configuration.

14. The delivery system of claim 1 , wherein the tongue assembly comprises one or more tongues.

15. The delivery system of claim 1 , wherein the multilumen cart comprises a bipod cover with a corresponding pattern with respect to a pattern of the stabilizing tool.

16. The delivery system of claim 1 , wherein the multilumen cart comprises a sealing mechanism, a stabilizing tool handle, a stabilizing tool lock rail, and one or more multilumen cart rails.

17. The delivery system of claim 16 , wherein the multilumen cart further comprises an actuation knob configured to open and lock the stabilizing tool handle to the multilumen cart.

18. The delivery system of claim 1 , wherein the actuation mechanism of the back assembly comprises:
