Patent number: 10743869Abstract: A stapling device for forming multiple tissue plications without needing to reload the device between plications is described. The device includes staple and anvil housings that move toward and away from a tissue-capture position. A cartridge holder in the staple housing supports a cartridge with multiple groups of offset staple slots, where the slots in each group are circularly arrayed about a cartridge center axis. A staple driver in the staple housing carries a plurality of arms for engaging and ejecting the staples in a first group of staples in the cartridge, when a tissue fold is captured between the cartridge assembly and anvil in the anvil housing. When the staple driver is retracted, after a tissue plication is formed, the cartridge assembly and tissue drive are indexed to eject the next-up group of staples.Type: GrantFiled: January 17, 2018Date of Patent: August 18, 2020Assignee: Boston Scientific Scimed, Inc.Inventors: David H. Cole, Jesica Ferro, Bretton Swope, Tyler Grubb, Daniel Balbierz

Patent number: 10299796Abstract: Described herein are endoscopic plicators passed transorally into the stomach and used to plicate stomach tissue by engaging tissue from inside of the stomach and drawing it inwardly. In the disclosed embodiments, the tissue is drawn inwardly into a vacuum chamber, causing sections of serosal tissue on the exterior of the stomach to be positioned facing one another. The disclosed plicators allow the opposed sections of tissue to be moved into contact with one another, and preferably deliver sutures, staples or other means for maintaining contact between the tissue sections at least until serosal bonds form between them. Each of these steps may be performed wholly from the inside of the stomach and thus can eliminate the need for any surgical or laparoscopic intervention. After one or more plications is formed, medical devices may be coupled to the plication(s) for retention within the stomach.Type: GrantFiled: May 8, 2015Date of Patent: May 28, 2019Assignee: Boston Scientific Scimed, Inc.Inventors: Daniel J. Balbierz, David H. Cole, Samuel T. Crews, Bretton Swope, Andrew C. Smith, John P. Lunsford, Fiona Sander

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.

Patent number: 7909837Abstract: Methods, devices and systems for forming magnetic anastomoses between two blood vessels. A first anastomotic component is removably supported by the distal end of a delivery device for attachment to a first vessel. The delivery device also supports a second anastomotic component that has been secured to a second blood vessel. The device is operated to secure the first component to the first vessel, couple the second component to the first component, and then release the components to complete the anastomosis. A robotic anastomosis system includes several robotic instruments that may be positioned through ports in a patient, used to secure an anastomotic component to a vessel, and then used to magnetically couple the components. Delivery devices for deploying magnetic anastomotic components include an actuator that uses magnetic repulsion to move the components into engagement with the inner and outer surfaces of the vessel wall.Type: GrantFiled: September 16, 2002Date of Patent: March 22, 2011Assignee: Medtronic, Inc.Inventors: Samuel Crews, J.

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.

Patent number: 7431727Abstract: Methods and devices for forming an anastomosis between hollow bodies utilize magnetic force to couple anastomotic securing components and connect the lumens of the hollow bodies. End-to-side, side-to-side and end-to-end anastomoses can be created without using suture or any other type of mechanical fasteners, although such attachment means may be used in practicing some aspects of the invention. The securing components have the ability to produce a magnetic field and may include materials or assemblies. A component may also be used to form a port into the lumen of a vessel, the component being attached to the vessel by mechanical and/or magnetic means. Magnetic components may include means for concentrating the magnetic flux between respective components to increase the attraction force, thereby enhancing the security of the anastomosis.Type: GrantFiled: February 6, 2004Date of Patent: October 7, 2008Assignee: Medtronic, Inc.Inventors: David H.

Patent number: 6932827Abstract: Methods and devices for forming an anastomosis between hollow bodies utilizes magnetic force to couple anastomotic securing components and create a fluid-tight connection between the lumens of the hollow bodies. End-to-side, side-to-side and end-to-end anastomoses can be created without using suture or any other type of mechanical fasteners, although any such attachment means may be used in conjunction with the magnetic attachment. The securing components have magnetic, ferromagnetic or electromagnetic properties and may include one or more materials, for example, magnetic and nonmagnetic materials arranged in a laminated structure. The system of anastomotic securing components may be used in many different applications including the treatment of cardiovascular disease, peripheral vascular disease, forming AV shunts for dialysis patients, etc., and may be sized and configured for forming an anastomosis to a specific hollow body, for example, a coronary artery or the aorta.Type: GrantFiled: March 4, 2002Date of Patent: August 23, 2005Assignee: Medtronic, Inc.Inventor: David H.
