Patent number: 8555891Abstract: Techniques for operating a subcutaneous implant device are disclosed. The implant device can be formed of a non-magnetic material that is compatible with diagnostics such as magnetic resonance imaging (MRI) and can include a rotor element that rotates under the influence of an external magnetic field. The implant device includes a tension relief mechanism for relieving excessive force applied between the implant device and a portion of a patient's tongue. A non-implanted device can include a stator and drive circuitry for generating the external magnetic field. The non-implanted device can receive a user command and can vary the external magnetic field based on the command. When activated by the magnetic field, the implant device can change its operating state to interact with the patient's body.Type: GrantFiled: May 21, 2010Date of Patent: October 15, 2013Assignee: Medtronic Xomed, Inc.Inventors: Adam Sharkawy, Koray Sahin, Adrian McVicker, Jon F. Moss, Casidy Domingo, Nikhil D. Bhat, Christopher Bagley, Anant V. Hegde, John M. Farbarik, George Y. Choi, Kasey Kai-Chi Li

Patent number: 8512360Abstract: Methods and devices for placing a target vessel in fluid communication with a source of blood and a target vessel. A conduit includes first portion adapted to be placed in fluid communication with a source of blood, such as a heart chamber, and a second portion adapted to be placed in fluid communication with a target vessel having a lumen, such as coronary artery. The first and second conduit portions are transverse to each other such that the conduit is generally T-shaped. The conduit lies on an exterior of the heart between the blood source and the target vessel and is configured to deliver blood in multiple directions into the lumen of the target vessel. For example, in an occluded coronary artery, blood flows both toward and away from the occlusion. The conduit may be flexible, rigid, collapsible or non-collapsible, and may be formed of synthetic vascular graft material, tissue, or a combination of the two.Type: GrantFiled: February 13, 2004Date of Patent: August 20, 2013Assignee: Medtronic, Inc.Inventors: A.

Publication number: 20110184505Abstract: Anastomotic components may be attached to hollow bodies or vessels by magnetic or mechanical force to create an anastomosis, form a port in a vessel, or repair a diseased vessel lumen. Anastomoses are created by coupling a first connection to an end of a vessel and then attracting it to a second connector secured to the side wall of another vessel. The connection between the first and second connectors may be solidly magnetic, solely mechanical, or a combination thereof. Also disclosed are methods and devices for treating diseased vessel lumens, for example abdominal aortic aneurysm. A plurality of docking members is attached to the vessel at solicited positions, and then one or more grafts is secured to the docking members in any suitable manner.Type: ApplicationFiled: April 5, 2011Publication date: July 28, 2011Applicant: Medtronic, Inc.Inventors: A. Adam Sharkawy, J. Greg Stine, David H. Cole, Samuel Crews, Darin C. Gittings, Adam Kessler, Mark J. Foley

Patent number: 7578828Abstract: Methods and devices for placing a conduit in fluid communication with a target vessel and a source of blood, such as the aorta or a heart chamber. The device may be actuated using one hand to place the conduit. The invention allows air in the conduit to be removed prior to placement of the conduit. The invention deploys the conduit in the target vessel by moving a sheath in a distal direction and then in a proximal direction. A conduit is provided with a reinforcing member to prevent kinking of the conduit, and a structure for preventing blockage of the conduit by tissue. A vessel coupling may be used to secure a conduit to a target vessel so as to preserve native blood flow through the vessel, and the conduit may be placed in fluid communication with a target vessel via a laparoscopic or endoscopic procedure.Type: GrantFiled: May 19, 2003Date of Patent: August 25, 2009Assignee: Medtronic, Inc.Inventors: Darin C.
