Pediatric esophageal atresia magnetic anastomosis system

A medical system for joining an upper esophageal sac and a lower esophageal sac in an infant, the medical system comprising:

• a first elongate member comprising a proximal end, a distal end and a first magnet operably connected to the distal end, the first magnet comprising an end portion configured to abut an interior surface of the upper esophageal sac;
• a second elongate member comprising a proximal end, a distal end, and a second magnet operably connected to the distal end, the second magnet comprising an end portion configured to abut an interior surface of the lower esophageal sac;
• a third elongate member comprising a proximal end, a distal end, a third magnet operably connected to the distal end and a spacer positioned distal to the third magnet, the third magnet comprising an end portion, the spacer comprising a first end portion operatively abutting the third magnet end portion of the third elongate member so that the third magnet is positioned between the distal end of the third elongate member and the first end portion of the spacer and the spacer comprising a second end portion configured to abut the interior surface of the upper esophageal sac;
• the third elongate member positionable in the upper esophageal sac after the first elongate member has been removed from the upper esophageal sac;
• and
• wherein a magnetic force between the first magnet of the first elongate member and the second magnet of the second elongate member is configured to pull the first magnet and the second magnet towards each other to lengthen the upper and lower esophageal sacs.
