Patent number: 11464528Abstract: A system for removing occlusive clot from a blood vessel comprises a catheter and an apparatus for generating a pulsatile vacuum force to pulse the pressure gradient at a distal end of the catheter. The pulse generator may be integral with or separate from the vacuum pump. The pulse generator may be applied to a flexible tubing between the vacuum pump and the proximal end of the catheter.Type: GrantFiled: July 25, 2017Date of Patent: October 11, 2022Assignee: NEURAVI LIMITEDInventors: Eamon Brady, David Vale, Michael Gilvarry, Brendan Casey, Marto Hoary, Adnan Siddiqui

Patent number: 11464941Abstract: A direct stream hydrodynamic catheter system is provided for the removal of thrombus, lesions and the like including provisions for the infusion of drugs, lysing fluids and the like into a blood vessel. Physician controlled powered direct fluid jet streams emanate from a fluid jet emanatory in the form of robust radially directed fluid jet streams to impinge upon and ablate difficult and strong thrombus and lesions within a blood vessel. Effluent aspiration is controlled by an exhaust regulator in the form of a roller pump, but effluent removal can be assistingly influenced by the fluid pressure associated with the radially directed fluid jet streams.Type: GrantFiled: June 13, 2019Date of Patent: October 11, 2022Assignee: Boston Scientific LimitedInventors: Michael J. Bonnette, Eric J. Thor, Debra M. Kozak, Douglas J. Ball, Stephen E. Weisel, David B. Morris, Richard R. Prather

Patent number: 11452534Abstract: A debris removal system includes an elongated shaft extending from a proximal end to a distal end and including a shaft lumen, the shaft being configured to be inserted through a bodily lumen to a target surgical site, a vibration motor coupled to the elongated shaft via a vibration collar, the vibration motor including a rotatable shaft and at least one weight coupled to the rotatable shaft, the weight being asymmetrically shaped about a central axis of the shaft such that rotation of the shaft creates vibrational energy along the length of the elongated shaft to dislodge debris within the target surgical site, and a vacuum pump connected to the elongated shaft and configured to vacuum dislodged debris from the target surgical site through the shaft lumen.Type: GrantFiled: October 26, 2018Date of Patent: September 27, 2022Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Peter J. Pereira, Martin Phelan, Vincent Lai

Patent number: 11446053Abstract: A tissue-removing catheter for removing tissue in a body lumen includes an elongate body having an axis and proximal and distal end portions spaced apart from one another along the axis. A turbine is fixed to the elongate body and is disposed at an intermediate position between the proximal and distal end portions of the elongate body. A rotatable tissue-removing element is at the distal end portion of the elongate body and is operatively coupled to the turbine such that the turbine imparts rotation of the tissue-removing element. The tissue-removing element removes the tissue from the body lumen as the tissue-removing element is rotated by the turbine.Type: GrantFiled: February 19, 2020Date of Patent: September 20, 2022Assignee: MEDTRONIC VASCULAR, INC.Inventors: Aram Jamous, John Kelly, Colin William Meade, Micheal Moriarty, Barry O'Connell, Grainne Carroll

Patent number: 11439426Abstract: An ultrasonic surgical blade includes a body having a proximal end, a distal end, and an outer surface. The distal end is movable relative to a longitudinal axis in accordance with ultrasonic vibrations applied to the proximal end. At least a portion of the outer surface of the body comprises a lubricious coating adhered thereto. The lubricious coating has a coefficient of friction that is less than the coefficient of friction of the outer surface of the body.Type: GrantFiled: March 6, 2019Date of Patent: September 13, 2022Assignee: Cilag GmbH InternationalInventors: David A. Witt, Jeffrey D. Messerly, Kevin L. Houser

Patent number: 11432794Abstract: The invention relates to a blood flow determination apparatus (5) comprising a speckle density determination unit (7) for determining a speckle density value being indicative of a level of a speckle density in an ultrasound image of an inner lumen of a blood vessel, which has been generated at an imaging location being behind an introduction location at which a fluid has been introduced into the blood vessel (20) with a known volumetric fluid flow rate. A blood flow rate determination unit (8) determines a blood flow value being indicative of a volumetric blood flow rate based on the determined speckle density value and the volumetric fluid flow rate. This allows determining the intravascular blood flow with an improved accuracy.Type: GrantFiled: September 18, 2017Date of Patent: September 6, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Christian Haase, Michael Grass

Patent number: 11426237Abstract: An electrosurgical instrument for applying to biological tissue RF electromagnetic energy and/or microwave frequency EM energy, wherein the instrument tip has a protective hull with a smoothly contoured convex undersurface facing away from a planar body, and wherein the planar body has a tapering distal edge, and wherein an underside of the planar body extends beyond the protective hull at the tapering distal edge. Also disclosed herein is an interface joint for integrating into a single cable assembly all of (i) a fluid feed, (ii) a needle movement mechanism, and (iii) an energy feed (e.g. a coaxial cable), and a torque transfer device for permitting controlled rotation of the cable assembly within the instrument channel of an endoscope. The interface joint and torque transfer device may be integrated as a single component.Type: GrantFiled: October 2, 2019Date of Patent: August 30, 2022Assignee: CREO MEDICAL LIMITEDInventors: Julian Mark Ebbutt, Christopher Paul Hancock, Steven Morris, Malcolm White, Brian Saunders
