  • Patent number: 11559320
    Abstract: Rolling tractor tube mechanical thrombectomy apparatuses that may be deployed from out of a catheter in situ are described herein. These apparatuses may be delivered out of a catheter from a collapsed delivery configuration within the catheter to a deployed configuration out of the catheter, in which the same catheter is re-inserted between a tubular tractor and an elongate puller. In particular, any of these methods and apparatuses may be adapted to work with a tractor tube having an open end that is biased open, including using an annular bias.

  • Publication number: 20220175389
    Abstract: Vaso-occlusive apparatuses, including implants, and methods of using them to treat aneurysms. The vaso-occlusive implants described herein include one or more soft and expandable braided member coupled to a pushable member such as a coil that maybe inserted and retrieved from within an aneurism using a delivery catheter as well as a friction element between the soft braided member and the coil. The friction element allows the relatively soft and elongate implant to be pushed out of a cannula without binding up within the cannula.

  • Publication number: 20220133348
    Abstract: Mechanical atherectomy and/or thrombectomy devices configured to remove obstructions (e.g., plaque material) of different consistencies and/or sizes from blood vessels. The devices may include a tractor comprising a flexible tube of material that inverts as it rolls over itself while being drawn into the open distal end of a catheter in a conveyor-like motion. The flexible tube can include features that facilitate engagement with the obstruction, enhance smooth tractor motion and/or promote movement control of the device within the blood vessel.

  • Publication number: 20210353316
    Abstract: Inverting tube thrombectomy apparatus for removing clot that are configured to prevent compression of the apparatus that may separate the distal end of the apparatus from the clot and may make it difficult to advance the apparatus to engage with the clot, particularly in a tortious vessel. The apparatuses and methods of using them described herein may be adapted to prevent tension in the flexible tube that is rolling and inverting over the distal end of the inversion support catheter when capturing a clot. Also described herein are inverting tube thrombectomy apparatus that are configured to reload either automatically or manually within the vessel to capture additional clot material.
