Patent number: 11376399Abstract: Some embodiments relate to a catheter system having a changeable or adjustable working length. The catheter system can comprise a proximal end, a distal end, and a first axial lumen configured to receive a guidewire formed through at least a portion of the catheter body. A first opening can be formed through a portion of the catheter body and be in communication with the first lumen. The sheath can be rotatable, axially movable, or otherwise changeable from at least a first position to a second position, wherein the sheath can substantially cover the first opening in the catheter body in the first position, and can substantially expose the first opening in the catheter body in the second position.Type: GrantFiled: November 3, 2017Date of Patent: July 5, 2022Assignee: BIOSENSORS INTERNATIONAL GROUP, LTD.Inventors: Kent C. B. Stalker, John D. Whitfield, Mark C. Bates, Peter J. D'Aquanni, Jason Andrew Habeger

Patent number: 8845583Abstract: An embolic protection device for use in a blood vessel when an interventional procedure is being performed in a stenosed or occluded region to capture any embolic material which may be created and released into the bloodstream during the procedure. The device includes a filtering assembly having a self-expanding strut assembly and a filter element attached thereto. In one embodiment, the filtering assembly is attached to the distal end of a guidewire and is deployed within the patient's vasculature as the guidewire is manipulated into the area of treatment. A restraining sheath placed over the filtering assembly in a coaxial arrangement maintains the filtering assembly in its collapsed position until it is ready to be deployed by the physician. Thereafter, the sheath can be retracted to expose the filtering assembly which will then self-expand within the patient's vasculature.Type: GrantFiled: January 10, 2007Date of Patent: September 30, 2014Assignee: Abbott Cardiovascular Systems Inc.Inventors: William J. Boyle, David H. Burkett, Andy E. Denison, Benjamin C. Huter, Scott J. Huter, Arkady Kokish, Kent C. B. Stalker, Chicheng Wang, John D. Whitfield

Patent number: 7959646Abstract: A system for enabling the insertion and removal of an embolic protection device, for capturing and retaining embolic debris which may be created during the performance of a therapeutic interventional procedure in a stenosed or occluded region of a blood vessel. The system, in an embodiment thereof, enables the device to be snap-fitted so as to engage the distal end of a guide wire, to provide a reference for positioning the device at a location distal to the interventional procedure site, and to enable an end of the device to be in tension, enabling a portion of the device to be in tension and another portion to be in compression, so as to assist in bending thereof in tortuous vasculature.Type: GrantFiled: June 26, 2007Date of Patent: June 14, 2011Assignee: Abbott Cardiovascular Systems Inc.Inventors: Benjamin C.

Patent number: 6695813Abstract: An embolic protection device includes a filtering assembly having a self-expanding strut assembly and a filter element. The filtering assembly can be attached to a guidewire and deployed within the patient's vasculature into an area of treatment. A restraining sheath maintains the filtering assembly in its collapsed position until it is ready to be deployed by the physician. Interventional devices can be delivered over the guidewire and any embolic debris created and released into the blood stream will enter the filtering assembly. The filtering assembly can be rotatably mounted on the guide wire and may include a dampening element which helps to prevent some shock force that may be transmitted along the guide to the deployed filtering assembly.Type: GrantFiled: December 30, 1999Date of Patent: February 24, 2004Assignee: Advanced Cardiovascular Systems, Inc.Inventors: William J. Boyle, David H. Burkett, Andy E. Denison, Benjamin C. Huter, Scott J. Huter, Arkady Kokish, Kent C. B. Stalker, Chicheng Wang, John D. Whitfield

Patent number: 6575996Abstract: A system for enabling the insertion and removal of an embolic protection device, for capturing and retaining embolic debris which may be created during the performance of a therapeutic interventional procedure in a stenosed or occluded region of a blood vessel. The system, in a version of an embodiment thereof, enables the device to expand upon deployment thereof so as to seal off the inner surface of a blood vessel, to inhibit the forming of a gap therein, for inhibiting embolic material from passing therethrough. The system, in another version of the embodiment thereof, enables the device to navigate through confined spaces in tortuous anatomy.Type: GrantFiled: June 29, 2001Date of Patent: June 10, 2003Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Andy Denison, Benjamin C.
