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: 9149609Abstract: The general purpose of the present invention is to provide a catheter for removal of an organized embolic thrombus, preferably in conjunction with a distal occlusion balloon guidewire. The present invention consists of three main components including a capture/delivery sheath, a capture sleeve of mesh attached to a tube and a grasping mechanism attached to another tube which is central to the other components. Operative structures in the form of manifolds are connected to such components in order to manipulate and control the relative positions of the capture/delivery sheath, the capture sleeve and the grasping mechanism. An embolic thrombus is engaged by the deployable automatically expanding serrated fingers of a grasping mechanism in combination with a deployable automatically expanding mesh capture sleeve. The capture/delivery sheath is maneuvered to cause compression of the serrated fingers and of the mesh capture sleeve for subsequent removal of the embolic thrombus.Type: GrantFiled: May 14, 2008Date of Patent: October 6, 2015Assignee: Embolitech, LLCInventors: Gary M.

Publication number: 20150151101Abstract: A catheter includes a pressure actuated seal within a manifold. A catheter body is coupled with the manifold, and a manifold lumen and catheter lumen are configured to receive pressurized fluids. The pressure actuated seal includes a pressure actuated seal element having a seal element lumen. The seal element lumen is in communication with the manifold and catheter lumens. The pressure actuated seal element is deformable between an open configuration and a sealed configuration. In the sealed configuration, the pressurized fluid in the manifold presses on the pressure actuated seal element along a first seal face. The pressure actuated seal element compresses inwardly around the seal element lumen according to the pressure of the pressurized fluid. In the open configuration, the pressure actuated seal element relaxes in the absence of the pressurized fluid, and the seal element lumen is open and configured to allow passage of an instrument.Type: ApplicationFiled: February 10, 2015Publication date: June 4, 2015Applicant: BOSTON SCIENTIFIC LIMITEDInventors: MICHAEL J.

Patent number: 8657777Abstract: Catheters including guidewire tubes having a limited length and methods of using the catheters are described. The catheters may be delivered over guidewires in procedures that are commonly referred to as rapid-exchange delivery. In some embodiments, the catheters may be miniature flexible thrombectomy catheters that may be used to remove thrombus or other unwanted material from a body blood vessel or other small regions of body cavities in which the distal portion of the catheter has smaller external dimensions than the larger proximal portion.Type: GrantFiled: January 14, 2013Date of Patent: February 25, 2014Assignee: Bayer Medical Care Inc.Inventors: Debra M.
