Patent number: 11963694Abstract: A thrombectomy device for removing thrombus from a body lumen comprises an elongated catheter member (2) having a distal part and a proximal part, a thrombus blocking body (5) disposed on the distal part of the catheter member and radially expansible between a contracted orientation and an expanded, thrombus-blocking, orientation, a thrombus capture body (3) disposed on the distal part of the catheter member in an axially spaced-apart relationship to the thrombus blocking body, and radially expansible between a contracted orientation and an expanded, thrombus-capture, orientation, deployment means actuable to deploy and retract the thrombus capture body and thrombus blocking body; and an elongated control arm operably connected to the thrombus capture body. The thrombus capture body is a cage having an inwardly tapering leading end, the elongated control arm is operably connected to the leading end of the cage, and a thrombus extractor or macerator mechanism is disposed within the cage.Type: GrantFiled: July 2, 2020Date of Patent: April 23, 2024Assignee: Vetex Medical LimitedInventors: Mark Bruzzi, Paul Heneghan, Saeid Kasiri Ghahi, Gerard O'Sullivan

Patent number: 11896257Abstract: A device suitable for use in a body lumen and comprises an elongated control member having a distal and a proximal end, and a radially expansible member disposed at or near the distal end and adapted for collection and/or shearing of matter (i.e. thrombus) from a wall of the body lumen (i.e. a vein or an artery). The radially expansible member has a proximal end and a distal end and is adjustable between a contracted orientation and an expanded orientation. The elongated control member comprising a proximal arm connected at or adjacent to the proximal end of the radially expansible member and a distal arm connected at or adjacent to the distal end of the radially expansible member such that movement of one arm relative to the other arm effects adjustment of the diameter or radial strength of the radially expansible member. The device comprises a control mechanism operatively connected to both arms and adapted to provide resistance to the movement of one arm relative to the other.Type: GrantFiled: August 5, 2022Date of Patent: February 13, 2024Assignee: Vetex Medical LimitedInventors: Mark Bruzzi, Saeid Kasiri Ghahi, Paul Heneghan

Patent number: 11317939Abstract: A thrombectomy device includes a handle at a proximal end portion of the device, a first arm connected to the handle, and a second arm extending to a distal end portion of the device. The device may also include a cage at the distal end portion of the device, the cage being adjustable between a contracted orientation and an expanded orientation, the cage including a cutting element disposed between a proximal end portion of the cage and a distal end of the cage, the cutting element including one or more of a round wire, a flat wire, or a blade configured to remove matter from a body lumen when the cage is in the expanded orientation, and a macerator extending within the first arm and the second arm, the macerator including a helical element.Type: GrantFiled: April 30, 2021Date of Patent: May 3, 2022Assignee: Vetex Medical LimitedInventors: Mark Bruzzi, Saeid Kasiri Ghahi, Paul Heneghan

Patent number: 11278307Abstract: A thrombectomy device includes a handle at a proximal end portion of the device, a cage at a distal end portion of the device, the cage being moveable between an expanded orientation and a contracted orientation, and a first tube extending from the proximal end portion of the device to at least a proximal end portion of the cage. The device also includes a second tube extending from the proximal end portion of the device to at least a distal end portion of the cage, and a self-adjusting control assembly including a biasing element coupled to one of the first tube or the second tube. The biasing element exerts an axial force to urge the cage toward the expanded orientation.Type: GrantFiled: April 30, 2021Date of Patent: March 22, 2022Assignee: Vetex Medical LimitedInventors: Mark Bruzzi, Saeid Kasiri Ghahi, Paul Heneghan
