Self-assembling magnetic anastomosis device having an exoskeleton
First Claim
1. A method of creating an anastomosis in a tissue comprising:
- mating a first and a second implantable device to the tissue,wherein each implantable device comprises a plurality of magnetic segments and an exoskeleton that covers a portion of the exterior of each of the magnetic segments,wherein the exoskeleton is adapted to direct the magnetic segments to self-assemble into a geometric shape.

Abstract
The invention is an implantable magnetic anastomosis device having an exoskeleton that directs self-assembly. The design allows the device to be delivered in a linear configuration using a minimally-invasive technique, such as endoscopy or laparoscopy, whereupon the device self-assembles into, e.g., a polygon. A coupled set of polygons define a circumscribed tissue that can be perforated, or the tissue can be allowed to naturally necrose and perforate. The device can be used to create anastomoses in a variety of tissues, such as tissues found in the gastrointestinal, renal/urinary, and reproductive tracts. New procedures for using anastomoses, e.g., surgical bypass are also disclosed.

11. A method for creating an anastomosis between proximal and distal bowel, comprising:
-
forming an anastomosis between a proximal portion and a distal portion of a bowel with a first and a second implantable device, wherein each implantable device comprises a plurality of magnetic segments and an exoskeleton that covers a portion of the exterior of each of the magnetic segments, wherein the exoskeleton is adapted to direct the magnetic segments to self-assemble into a geometric shape, thereby creating a portion of partially bypassed bowel; and leaving the partially bypassed bowel unobstructed so that the partially bypassed bowel can continue its native physiological function. - View Dependent Claims (12, 13, 14, 15, 16)
