Patent number: 11607223Abstract: Methods and apparatus for safely forming anastomoses comprise magnetic members configured to accommodate different tissue types and patients of differing size and weight. The magnetic members may comprise first and second magnetic members configured to engage each other with a force sufficient to form anastomosis while taking a sufficiently long time to allow the intestinal walls to fuse together. The first and second magnetic members can be configured to form anastomoses between both similar and different types of intestinal tissue. An elongate surgical placement instrument can be configured to engage and manipulate the first and second magnet members through the intestinal wall from outside the intestinal wall in order to place each of the magnetic members at desired locations.Type: GrantFiled: June 28, 2018Date of Patent: March 21, 2023Assignee: The Regents of the University of CaliforniaInventors: Michael R. Harrison, Dillon A. Kwiat, Richard J. Fechter

Patent number: 8623036Abstract: A magnamosis system for auto-anastomosing a region of the body using implants with magnetic members that may be individually delivered to different locations in the body. The implants with their magnetic members have a mating surface and polar alignment that generates an attractive force to compress tissue in the region between them. The tissue in the region necroses as a result of the compressive force such that tissue surrounding the necrosed tissue heals together to form an anastomosis.Type: GrantFiled: March 15, 2013Date of Patent: January 7, 2014Assignee: The Regents of the University of CaliforniaInventors: Michael R.

Patent number: 8439915Abstract: Systems and methods are disclosed for manipulating an anatomical feature within the body of the patient. An implant such as an internal jackscrew is implanted at the anatomical and has first and second attachment points that secure to spaced-apart locations on the anatomical feature, an internal rotor coupled to the jackscrew, and is configured to drive motion of the jackscrew to manipulate the anatomical feature. The system further includes an external rotor that is magnetically coupled to the internal rotor such that rotation of the external rotor at an exterior location to the patient's body affects a corresponding internal rotation of the internal rotor to manipulate the anatomical feature.Type: GrantFiled: February 22, 2007Date of Patent: May 14, 2013Assignee: The Regents of the University of CaliforniaInventors: Michael R.

Patent number: 8043290Abstract: Methods and apparatus for incrementally manipulating an internal body member of a patient are disclosed. The apparatus has a magnetic implant adapted to be received on a location of the body member, a platform external to the patient, and a magnetic member coupled to the platform, wherein the magnetic member generates a magnetic force between the implant and the platform to incrementally manipulate the body member. The implant and external magnetic member are preferably rare earth magnets or an array of rare earth magnets, and are configured to generate an attractive or repulsive force between the implant and the platform to reposition, reorient, deform, or lengthen the body member.Type: GrantFiled: September 29, 2004Date of Patent: October 25, 2011Assignee: The Regents of the University of California, San FranciscoInventors: Michael R.
