1. A system for forming an anastomosis between two adjacent walls of a digestive tract, the system comprising:
first and second magnetic implants configured to magnetically couple to each other through the two adjacent walls of the digestive tract to compress a portion of the two adjacent walls therebetween and form a necrotic area that becomes surrounded by a scarred edge following a healing time period, at least one of the first and second magnetic implants comprising:
a magnetic member comprising a magnet;
a non-magnetic member provided in a longitudinally adjacent relationship relative to the magnetic member;
the magnetic member and the non-magnetic together defining a substantially flat compression surface configured to contact wall tissue of the portion of the two adjacent walls; and
a defeatable portion located between the magnetic member and the non-magnetic member, the defeatable portion being configured to temporarily retain the magnetic member and the non-magnetic member engaged together during the healing time period.
