Patent number: 10751158Abstract: Instrumentation for percutaneous delivery of blood filtration devices to atrial appendages includes a curved access sheath and a delivery tube. A compressed filter device attached to a tether wire is loaded in the delivery tube. The access sheath and the delivery tube can be mechanically locked and moved together to place the device in a suitable deployment position. The device is deployed by expelling it from the delivery tube either by retracting the delivery tube over the tether wire, or by moving the tether wire forward through the delivery tube. A filter membrane in the deployed device extends across the appendage ostium to filter blood flow through the ostium. The filter membrane is configured to present a flat surface to atrial blood flow past the ostium.Type: GrantFiled: January 8, 2018Date of Patent: August 25, 2020Assignee: Atritech, Inc.Inventors: Gregg S. Sutton, Jeffrey Welch, Dean A. Peterson, John B. Bridgeman, Bruce R. Youngberg

Patent number: 9913652Abstract: An implantable medical device for insertion in the left atrial appendage includes a cap coupled to a frame. The cap constrains movement of the legs of the frame during collapse and expansion of the device, such that the device can be deployed, recalled and redeployed without the device being damaged or the legs of the frame getting tangled.Type: GrantFiled: November 13, 2015Date of Patent: March 13, 2018Assignee: Atritech, Inc.Inventors: John B. Bridgeman, Gregg Sutton, Christopher J. Clark

Publication number: 20160051358Abstract: Instrumentation for percutaneous delivery of blood filtration devices to atrial appendages includes a curved access sheath and a delivery tube. The curved access sheath is coursed through the patient's vasculature to gain transseptal access to a left atrial appendage. A compressed filter device attached to a tether wire is loaded in the delivery tube. The loaded delivery tube is advanced through the pre-positioned access sheath to place the device in a deployment position. The access sheath and the delivery tube can be mechanically locked and moved together to place the device in a suitable deployment position. The device is deployed by expelling it from the delivery tube either by retracting the delivery tube over the tether wire, or by moving the tether wire forward through the delivery tube. The expelled device, which is not constrained by the delivery tube walls, self expands to its useful size in the subject atrial appendage.Type: ApplicationFiled: July 22, 2015Publication date: February 25, 2016Applicant: ATRITECH, INC.Inventors: Gregg S.

Patent number: 6945951Abstract: Cross stream thrombectomy catheter and system for fragmentation and removal of thrombus or other material from blood vessels or other body cavities. High velocity saline jets emitted from a toroidal loop jet emanator or other jet emanator in a catheter distal end entrain fluid through inflow orifices, and with flow resistances create a back-pressure which drives cross stream streams through outflow orifices in a radial direction and thence radially and circumferentially to apply normal and drag forces on thrombotic deposits or lesions in the blood vessel or other body cavity, thereby breaking apart and transporting thrombus particles to be entrained through the inflow orifices, whereupon the high velocity jets macerate the thrombus particles which then transit an exhaust lumen or recirculate again via the outflow orifices.Type: GrantFiled: August 16, 2001Date of Patent: September 20, 2005Assignee: Possis Medical, Inc.Inventors: Michael J. Bonnette, John Edward Morris, Steven E. Wiesel, John B. Bridgeman, Debra M. Kozak, Rosemary C. Beaupre, Mark L. Jenson, Cindy M. Setum, Robert C. Dutcher
