Publication number: 20210353421Abstract: An implantable prosthetic valve includes an outer tubular wall or other body having an axial passage extending from an inlet end to an outlet end. The wall may be constructed of a flexible biocompatible material, and a pair of apposed valve leaflets is usually disposed in the axial passageway of the outer tubular wall or body. Each valve leaflet has an inlet edge, an outlet edge, and a pair of lateral edges extending between the inlet edge and the outlet edge. The outlet edges are configured to be normally open to allow unrestricted fluid flow and close together when fluid pressure is applied to the outlet end. In some instances, the inlet edge, the outlet edge, and the pair of lateral edges of each leaflet are integrated along their entire lengths into the outer tubular wall. In other instances, the leaflets may be formed as a separate structure or assembly that is attached within the tubular wall or body.Type: ApplicationFiled: June 30, 2021Publication date: November 18, 2021Applicant: Renovo Medsolutions, LLCInventor: Lee Bolduc

Patent number: 10792468Abstract: An endovascular guide catheter includes a guide tube and a handle. The flexible guide tube has a distal end portion configured to deflect via actuation of a pull wire. The handle is coupled to the guide tube and comprises a steering assembly configured to actuate the pull wire to deflect the distal end portion of the guide tube. The steering assembly can comprise a stationary rack, a gear, a reel, and a slider. The gear engages the rack and the reel is coupled to and configured to rotate with the gear. The pull wire is coupled to the reel such that rotation of the reel causes the pull wire to wind or unwind around the reel. The slider is adapted for translation relative to the rack. Translation of the slider translates the reel relative to the rack and rotation of the gear along the rack rotates the reel.Type: GrantFiled: December 13, 2018Date of Patent: October 6, 2020Assignee: Medtronic Vascular, Inc.Inventors: Lee Bolduc, Jimmy Jen

Patent number: 10779970Abstract: A fenestrated aortic cuff is configured to be delivered endovascularly to a target region, deployed, fastened, and sealed to a vessel wall, e.g., in a neck region of an aortic aneurysm. Example fenestrated cuffs provide a suitable landing zone for a commercially available endograft, which may be, in some cases, positioned below or above the renal arteries in order to complete exclusion of an abdominal aortic aneurysm (AAA) or a thoracic aortic aneurysm (TAA), respectively, from systematic circulation. In some cases, fenestrated cuff function is facilitated and improved by employing active fixation and sealing mechanisms, including, e.g., helical fasteners, which may allow deployment of the fenestrated cuff in short neck regions with limited sealing area.Type: GrantFiled: April 18, 2018Date of Patent: September 22, 2020Assignee: MEDTRONIC VASCULAR, INC.Inventors: Lee Bolduc, Bart Muhs

Patent number: 10357230Abstract: A guide device establishes a guide passage through a guide tube, through which an operative tool can be deployed into an interior body region for use. A steering assembly, in use, deflects or bends the distal end region of the guide tube, so that the operative tool can be placed in a desired orientation with respect to tissue. The steering assembly is desirable configured for single handed operation by the clinician. The steering assembly is also desirably configured to provide a mechanical advantage sufficient to translate relatively small increments of clinician control into relatively larger increments of guide tube deflection. In one arrangement, the steering assembly includes a rack and pinion linkage system. In another arrangement, the steering assembly includes a pivoting lever system.Type: GrantFiled: March 16, 2016Date of Patent: July 23, 2019Assignee: Medtronic Vascular, Inc.Inventor: Lee Bolduc

Patent number: 10299791Abstract: Method and apparatus for implanting radially expandable prostheses in the body lumens rely on tacking or anchoring of the prostheses with separately introduced fasteners. The prostheses may be self-expanding or balloon expandable. After initial placement, a fastener applier system is introduced within the expanded prostheses to deploy a plurality of fasteners at least one prosthesis end, usually as each end of the prosthesis. The fasteners are usually helical fasteners which are delivered from a helical track in the fastener applier by rotation with a rotator wire. The fasteners will be applied singly, typically in circumferentially spaced-apart patterns about the interior of each end of the prosthesis.Type: GrantFiled: March 21, 2016Date of Patent: May 28, 2019Assignee: MEDTRONIC VASCULAR, INC.Inventor: Lee Bolduc

Patent number: 10194905Abstract: Devices, systems, and methods for implanting expandable prostheses in the body lumens rely on stapling or anchoring the prostheses with separately introduced fasteners. The prostheses may be self-expanding or balloon expandable, and may include a single lumen or more than one lumen. After initial placement, a stapling system is introduced within the expanded prosthesis to deploy a plurality of fasteners to at least one prosthesis end. The stapling system may apply a force to the prosthesis to modify the shape of the prosthesis to conform to the shape of the vessel wall. The stapling system can be deflected in one or more distinct steerable segments. A lumen extension or lumens may be coupled to the prosthesis to extend the reach of the prosthesis within the implantation site. Fasteners may also be applied to the lumen extensions.Type: GrantFiled: August 24, 2016Date of Patent: February 5, 2019Assignee: MEDTRONIC VASCULAR, INC.Inventors: Lee Bolduc, Jimmy Jen
