Abstract
Systems and methods for forming an anastomosis between two adjacent walls of a digestive tract are provided. The system can include first and second magnetic implants configured to magnetically couple through 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. The magnetic implant can include a magnetic member and a non-magnetic member. The system can include a retention member extending outwardly from a corresponding one of the first and second magnetic implants, the retention member being configured to retain the magnetic implants in position and prevent passage thereof through the necrotic area during the healing time period, and to maintain an engagement between the magnetic member and the non-magnetic member during the healing time period and enable disengagement thereof following the healing time period.
