Publication number: 20240082017Abstract: An implant delivery device may include an implant holding portion proximate the distal end, the implant holding portion being configured to retain a sheet-like implant during implantation of the implant. In addition, the implant holding portion may be configured to receive the implant with a fixed implant supporting flange member configured to support the implant on one side, and a movable implant supporting flange member. The movable implant supporting flange member may be configured to be slidable between a distal position and a proximal position, wherein, in the distal position, the movable implant supporting flange member and secures the implant against the fixed implant supporting flange member, and in the proximal position, the movable implant supporting flange member is withdrawn from the distal end of the implant delivery device, thus enabling release of the implant.Type: ApplicationFiled: November 15, 2023Publication date: March 14, 2024Inventors: R. Sean Churchill, Robert J. Ball, Douglas Snell, Isaac Running, Christopher K. Jones, Brandon Bryant

Publication number: 20230031241Abstract: 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: ApplicationFiled: October 10, 2022Publication date: February 2, 2023Applicant: 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: 9585686Abstract: An infusion flow guidewire and a system including an infusion flow guidewire. The minimal cross section flexible infusion flow guidewire includes a nitinol hypotube, a flexible tip having a closed distal end, a coil, a core wire and at least one distally located rearwardly directed jet orifice for infusion of fibrinolytics and for introduction of high pressure fluids for maceration and rearwardly directed flow of thrombus debris located in tortuous small sized vessels. Apparatus, some of which is removably attachable, is provided in the system for grasping members of the invention for rotational torqueing and for longitudinal actuation along and within the vasculature.Type: GrantFiled: December 9, 2013Date of Patent: March 7, 2017Assignee: BOSTON SCIENTIFIC LIMITEDInventors: John Riles, Douglas J.

Patent number: 9238119Abstract: Fluid infusion systems and fluid couplings are described herein. The infusion systems may include one or more fluid couplings used to make fluidic connection between a supply line and delivery tubing. The fluid couplings separate the functions of providing a seal around a delivery tube and retaining the delivery tube within the fluid coupling. The seal provided around the delivery tube prevents leakage around an exterior surface of a delivery tube such that fluid passing through the coupling must pass through the delivery tube rather than leak around the delivery tube. The structure used to retain the delivery tube in the fluid coupling prevents ejection of the delivery tube from the coupling due to the fluid pressures present in the coupling. The separate functions are performed by different structures within the fluid couplings.Type: GrantFiled: August 11, 2011Date of Patent: January 19, 2016Assignee: BOSTON SCIENTIFIC LIMITEDInventors: Eric J. Thor, Douglas J. Ball, Lief E. Leirfallom, Michael J. Bonnette, Jason M. Bronstad, Jason Anderson
