Patent number: 11786699Abstract: A suction catheter system is described with a suction nozzle that can extend from a guide catheter of the like. The suction nozzle can be positioned by tracking the suction nozzle through a vessel while moving a proximal portion of the suction extension within the lumen of the guide catheter. A suction lumen extends from the proximal end of the guide catheter through at least part of the guide catheter central lumen and through the suction tip. Desirable suction flow can be established using the guide lumen to facilitate the suction. Also, a delivery catheter is described with an elastic tip that can track closely over a guidewire. The elastic tip of the delivery catheter can be expanded to provide for the delivery of medical devices past the tip.Type: GrantFiled: May 19, 2020Date of Patent: October 17, 2023Assignee: MIVI Neuroscience, Inc.Inventors: Matthew F.

Patent number: 11786254Abstract: Systems, methods, and devices for the treatment of acute ischemic stroke that provide immediate blood flow restoration to a vessel occluded by a clot and, after reestablishing blood flow, address the clot itself Immediate blood flow restoration advantageously can facilitate natural lysis of the clot and also can reduce or obviate the concern for distal embolization due to fragmentation of the clot. Several embodiments of the invention provide for progressive, or modular, treatment based upon the nature of the clot. For example, the progressive treatment can include immediate restoration of blood flow, in-situ clot management, and/or clot removal depending on the particular circumstances of the treatment. The in-situ clot management can include, for example, lysis, maceration, and/or removal.Type: GrantFiled: November 16, 2020Date of Patent: October 17, 2023Assignee: COVIDIEN LPInventors: David A. Ferrera, Andrew H. Cragg, John Fulkerson

Patent number: 11779459Abstract: Apparatus and methods are described including a valve frame defining a frame aperture and at least one arm attached to a portion of the valve frame on a ventricular side of said frame aperture. The at least one arm is configured to extend radially from the portion of the valve frame such that a chord receiving surface of the arm is sized and shaped to deploy among a region of the chords of the native mitral valve. The arm is curved, with an interior of the arm facing a direction in which the valve frame is configured to be rotated during deployment of the prosthetic mitral valve apparatus within the native mitral valve and with the arm having a concavely rounded leading edge facing at least partially in a circumferential direction. Other applications are also described.Type: GrantFiled: June 16, 2021Date of Patent: October 10, 2023Assignee: TEL HASHOMER MEDICAL RESEARCH INFRA AND SVCS LTDInventors: Ehud Raanani, Boris Orlov, Boaz Harari, Oded Meiri, Lichen Rozitsky

Patent number: 11730488Abstract: A tourniquet assembly is provided comprising an external band and an internal band with a first and second semi-permanent adhesive members. The external band has a first connecting member affixed thereto and a second connecting member removably connected thereto. The internal band is designed to form a loop having a circumference around a limb for constricting blood flow in the limb when the external band forms a loop when the first connecting member is attached to the second connecting member. The tourniquet assembly further comprises a tensioning member connected to the internal band and configured to apply direct tension to the internal band without applying direct tension to the external band. Herein, the circumference formed by the internal band is reduced when the tensioning member is actuated, thereby compressing the limb when the tourniquet assembly is placed around the limb, and thereby reducing blood flow to the limb.Type: GrantFiled: February 25, 2022Date of Patent: August 22, 2023Inventor: Randy Watts

Patent number: 11717430Abstract: A stent delivery system includes a shaft extending from a proximal end of the system into a delivery tip at a distal end. The shaft includes a coil and a stent bed. A stent is loaded onto the stent bed and has a first portion at its distal end having a greater flexibility than a second portion at its proximal end. Sheathing is movable over the stent bed between pre-deployed and deployed positions. The sheathing includes a flexible section at the sheathing distal end, a semi-flexible section adjacent the flexible section, and a stiff section adjacent the semi-flexible section. The delivery tip is more flexible than the combination of the stent bed, the first portion of the stent, and the flexible section of the sheathing, which is more flexible than the combination of the stent bed, the second portion the stent, and the flexible section of the sheathing.Type: GrantFiled: March 5, 2021Date of Patent: August 8, 2023Assignee: Serenity Medical, Inc.Inventor: Jeffrey P.
