Patent number: 11337714Abstract: Devices for restoring blood flow to facilitate lysis of clots and/or enable capture of clots are disclosed. The devices can be configured to be disposed within a lumen of a microcatheter that is inserted within neurovasculature above a carotid siphon to a location of a clot. The devices can include an elongate pusher member and a self-expandable capturing member coupled to a distal end of the elongate pusher member. The capturing member can comprise a generally cylindrical body having an cell structure that is configured to compress the clot against an inner wall of the neurovasculature and capture the clot at least partially on a surface of the generally cylindrical body upon deployment of the capturing member from the microcatheter, thereby restoring blood flow to the neurovasculature downstream of the clot.Type: GrantFiled: September 5, 2019Date of Patent: May 24, 2022Assignee: COVIDIEN LPInventors: David Ferrera, Andrew Cragg, John Fulkerson

Patent number: 10814045Abstract: The invention provides devices and methods for aneurysm treatment using a material that minimizes susceptibility artifacts in MRA images. Since images are not obscured by susceptibility artifacts associated with the aneurysm treatment device, those images are useful and reliable for evaluating the success of treatment. The material is preferably a non-ferromagnetic metal alloy and may include one or a combination of cobalt, nickel, chromium, and molybdenum. In certain embodiments, the material is a 35Cobalt-35Nickel-20Chromium-10Molybdenum-Low Titanium alloy medical-grade material.Type: GrantFiled: October 30, 2015Date of Patent: October 27, 2020Assignee: BALT USAInventors: Randall Takahashi, David Ferrera

Publication number: 20180125697Abstract: The present invention relates to fluid flow diversion in medical procedures, and, more particularly, to a valve assembly for preventing retrograde flow of urine from a collection device into a urinary catheter so as to reduce the risk of and/or prevent catheter-associated urinary tract infection (CAUTI). The valve assembly of the present invention is a discrete, stand-alone valve assembly configured to provide a fluid connection between a urinary catheter (e.g., Foley catheter), and a collection device (e.g., urine drainage bag) or the tubing for coupling the catheter to the collection device. The valve assembly is configured to permit antegrade flow of urine from the catheter into the collection device, while preventing retrograde flow of urine (e.g., backflow) from the collection device into the catheter, thereby reducing the risk of CAUTI.Type: ApplicationFiled: May 10, 2016Publication date: May 10, 2018Inventor: David Ferrera

Patent number: 9539122Abstract: An apparatus for treating vascular aneurysms includes an occlusive support device comprised of one or more support members. The occlusive device has, an end cap member and an anchoring member. The end cap member is comprised of at least one of one or more of the support members. The end cap member has openings and the end cap member comprises a reactive material that is configured to hydrate upon delivery of the device and to reduce the size of said openings. The device is configured so that the occlusive members can be positioned in the blood vessel proximate the neck of a vascular aneurysm, the reactive material hydrates and increases the resistance to blood flow into the aneurysm, and the anchoring member anchors the device in the blood vessel without occluding flow through the blood vessel.Type: GrantFiled: March 24, 2014Date of Patent: January 10, 2017Assignee: MicroVention, Inc.Inventors: Thomas H.

Patent number: 9320532Abstract: 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: February 2, 2015Date of Patent: April 26, 2016Assignee: Covidien LPInventors: David Ferrera, Andrew Cragg, John Fulkerson
