Publication number: 20240285389Abstract: An intravascular emboli capture and retrieval system for intravascular embolism protection and embolism removal or maceration. Guidewire mounted proximally and distally located multiple opening filters are deployed within the vasculature and used to part, divide and macerate embolic debris and to capture such embolic debris within the confines thereof. A deployable flexible preformed memory shaped capture sleeve is alternatively used to collapse one or more filters and embolic debris therein for subsequent proximal withdrawal from the vasculature.Type: ApplicationFiled: January 11, 2024Publication date: August 29, 2024Inventors: Michael J. Bonnette, Richard R. Prather, Eric J. Thor, Stephen E. Weisel, Douglas L. Ball, David B. Morris, Debra M. Kozak, Gary Ansel

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: 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
