1. A system for delivering a heart implant comprising:
a) a first catheter having a proximal end and a distal end, wherein the first catheter comprises:
i) a first lumen extending through a length of the first catheter;
ii) a first magnet disposed along a distal portion of the first catheter, wherein the first magnet includes a first magnetic pole and a second magnetic pole; and
iii) a first guide channel disposed in the distal portion of the first catheter and extending along a first longitudinal axis, the first guide channel being coextensive with the first lumen and having a first side hole located proximal along the distal portion of the first catheter relative to the first magnetic pole; and
b) a second catheter having a proximal end and a distal end, wherein the second catheter comprises:
i) a second lumen extending through a length of the second catheter;
ii) a second magnet disposed at the distal end of the second catheter, wherein the second magnet includes a third magnetic pole and a fourth magnetic pole; and
iii) a second guide channel disposed at the distal end of the second catheter and extending along a second longitudinal axis, the second guide channel being coextensive with the second lumen and having a second side hole on a side wall of the second catheter and adjacent the second magnet,
wherein the first side hole and the second side hole are aligned in a plane parallel to the first longitudinal axis and the second longitudinal axis, and the second side hole is oriented distal along the distal portion of the first catheter relative to the first side hole, when the first magnet and the second magnet are magnetically coupled.
