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.

Patent number: 10314609Abstract: A thrombectomy catheter includes a catheter body having a catheter lumen. An outflow orifice is positioned along a catheter perimeter. A fluid jet emanator communicates with a high pressure tube. The fluid jet emanator includes at least one jet orifice for directing a fluid jet from the fluid jet emanator through the catheter lumen toward the outflow orifice. The fluid jet emanator provides a jet stream from the catheter body through the outflow orifice. The jet stream includes first and second stream portions. An entrainment fluid flow circuit includes at least the first stream portion, and the entrainment fluid flow circuit entrains particulate and macerates the particulate therein. An exhaust fluid flow path includes the second stream portion, and the exhaust fluid flow path draws entrained particulate from the entrainment fluid flow circuit at a location exterior to the catheter body and directs it toward the catheter proximal portion.Type: GrantFiled: December 5, 2017Date of Patent: June 11, 2019Assignee: BOSTON SCIENTIFIC LIMITEDInventors: Michael J.
