System and method for retrieving a magnetic implant for forming an anastamosis in the digestive tract

A retrieving device for insertion within a digestive tract of a patient, the retrieving device comprising:

• a flexible housing having a proximal portion engageable with a delivery wire and a distal portion opposite the proximal portion, the flexible housing comprising:
• a housing wall defining a retriever magnet receiving cavity;
• and
• a plurality of retriever magnets provided in series within the retriever magnet receiving cavity, the retriever magnets being distributed within the retriever magnet receiving cavity so as to define a non-magnetic portion and a magnetic portion of the retrieving device thereby enabling the retriever magnets of the plurality of retriever magnets to move freely and be subjected to a translational displacement in a longitudinal direction within the retriever magnet receiving cavity;
• the retriever magnets having a diameter sized to define a displacement void between an outer surface of the retriever magnets and an inner surface of the housing wall of the flexible housing;
• wherein the retrieving device is magnetically engageable with a first magnetic implant of a pair of magnetic implants configured for forming an anastomosis between two adjacent walls of the digestive tract of the patient.
