Magnetic enteral gastrostomy
First Claim
1. A method for performing a gastrostomy, said gastrostomy producing an opening from the interior of a patient'"'"'s stomach through the patient'"'"'s stomach wall and abdominal wall, comprising the steps of:
- introducing a first magnet into the stomach;
placing said first magnet on the stomach wall adjacent to the abdominal wall;
placing a second magnet on the outside of the abdominal wall opposite, and relative to, said first magnet whereby said first magnet and said second magnet are drawn together compressing a portion of the stomach wall and a portion of the abdominal wall to produce local ischemia between said first magnet and said second magnet; and
allowing said first magnet and said second magnet to remain in place for a time sufficient to form a tract substantially through the stomach wall and the abdominal wall thereby forming a gastrostoma adherent to the abdominal wall.

Abstract
A method of performing a gastrostomy by ischemia-induced tissue remodeling. To accomplish this, a small intragastric disk is magnetically coupled to a larger disk on the outside of the abdominal wall. The attractive magnetic force acting on the two disks occludes blood flow to the intervening tissue. The ensuing local ischemia results in infarction and resorption of that tissue. As the tissue is resorbed, the smaller intragastric disk is drawn toward the larger disk on the outside of the abdominal wall creating a stoma in its path and leaving the stomach adherent to the abdominal wall around the perimeter of the smaller disk.

12. Apparatus for performing a gastrostomy, said gastrostomy producing an opening from the interior of a patient'"'"'s stomach through the patient'"'"'s stomach wall and abdominal wall, comprising:
-
a first magnet adapted to be placed inside the stomach on the stomach wall adjacent to the abdominal wall; a second magnet adapted to be placed on the outside of the abdominal wall opposite, and relative to, said first magnet whereby said first magnet and said second magnet are drawn together compressing a portion of the stomach wall and a portion of the abdominal wall to produce local ischemia of tissue between said first magnet and said second magnet; and external means, adapted to be placed outside the abdominal wall, for keeping said second magnet in place for a time sufficient to form a tract substantially through said stomach wall and said abdominal wall thereby forming a gastrostoma adherent to said abdominal wall. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A kit for performing a gastrostomy, said gastrostomy producing an opening from the interior of a patient'"'"'s stomach through the patient'"'"'s stomach wall and abdominal wall, comprising:
- a first magnet, adapted to be placed in the patient'"'"'s stomach;
a second magnet, said magnets having sufficient attractive force to engage one another when said first magnet is in the stomach and said second magnet is placed on the outside of the abdominal wall, opposite and relative to said first magnet; and
external means, adapted to be placed outside the abdominal wall, for keeping said second magnet in place. - View Dependent Claims (25, 26, 27)
