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: 20230044273Abstract: A matter elimination catheter includes a catheter body extending from a catheter proximal portion to a catheter distal portion. The catheter body includes an infusion lumen, an aspiration lumen fluidly isolated from the infusion lumen, and a septum interposed between the infusion and aspiration lumens. A drive shaft is within the infusion lumen and is configured to provide rotation near the catheter distal portion. A guide wire lumen is within the drive shaft, and the infusion lumen, the drive shaft and the guide wire lumen are fluidly separated from the aspiration lumen with the septum. In one example, fluid bearings are formed between one or more of the catheter body and drive shaft or the drive shaft and a guide wire or guide wire liner when supplied with infusion fluid through the infusion lumen.Type: ApplicationFiled: October 18, 2022Publication date: February 9, 2023Applicant: BOSTON SCIENTIFIC LIMITEDInventors: Michael J.

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: 7615031Abstract: A gas inflation/evacuation system incorporating a multiple element valved guidewire assembly having an occlusive device for use in thrombectomy or other vascular procedures includes a multiple element valved guidewire assembly having an occlusive balloon removably and sealingly connectible to an included manifold assembly where a guidewire tube defines a lumen for inflation or deflation of the occlusive balloon. A first syringe for evacuating the lumen and a second syringe for introducing a biocompatible gas into the lumen to inflate the occlusive balloon that is in fluid communication with the lumen a plurality of times are included. A sealing valve arrangement selectively seals the proximal portion of the guidewire tube to control inflated or deflated states of the occlusive balloon.Type: GrantFiled: September 1, 2005Date of Patent: November 10, 2009Assignee: MEDRAD, Inc.Inventors: Michael J.
