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: 8672991Abstract: A deployment control system provides controlled deployment of an embolic protection device which may include a guide wire, an expandable filter attached to the guide wire near its distal end, and a restraining sheath that maintains the expanded filter in a collapsed position. The deployment control system includes a torque control device which allows the physician to torque the guide wire into the patient's anatomy and a mechanism for preventing the guide wire from buckling as the restraining sheath is being retracted to deploy the expandable filter. A recovery control system for recovering the embolic protection device includes an inner catheter which extends within a lumen of an outer recovery sheath in a coaxial arrangement. A distal portion of the inner catheter extends beyond another recovery sheath during advancement of the recovery system into the vasculature. The recovery sheath can be advanced over the inner catheter to collapse the expandable filter.Type: GrantFiled: March 15, 2010Date of Patent: March 18, 2014Assignee: Abbott Cardiovascular Systems Inc.Inventors: William J.

Patent number: 8282679Abstract: Stent designs for use in vessels, such as the carotid and coronary arteries, are disclosed. The stents consist of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting members placed so that the stent is flexible in a longitudinal direction. The cylindrical elements form a generally serpentine wave pattern transverse to the longitudinal axis between alternating valley portions and peak portions. The interconnecting members are attached to the double-curved portions to connect a cylindrical element to an adjacent cylindrical element and interconnecting members are attached to the inverted double-curved portions to connect the cylindrical element to the other adjacent cylindrical element. The stent designs include both a six crown and an eight crown stent which exhibit flexibility and sufficient radial strength to support the vessel.Type: GrantFiled: August 25, 2010Date of Patent: October 9, 2012Assignee: Abbott Cardiovascular Systems Inc.Inventor: Andy E.

Patent number: 7976560Abstract: An expandable frame for an embolic filtering device used to capture embolic debris in a body vessel includes a first half frame having a first control arm connected to a second control arm by a partial loop and a second half frame having a first control arm connected to a second control arm by a partial loop. The partial loops cooperatively form a composite loop for attachment of a filtering element which will expand in the body vessel to capture embolic debris entrained in the fluid of the vessel. The lengths and positioning of the first and second control arms of each half frame can be varied to create an expandable frame which conforms to the size and shape of the body vessel in which the filtering device is deployed. Additionally, the radius of the partial loops, along with the length of the arc of the partial loops, can be varied on each of the frames to create a composite filtering assembly that can easily adapt to the size and shape of the body vessel.Type: GrantFiled: January 17, 2007Date of Patent: July 12, 2011Assignee: Abbott Cardiovascular Systems Inc.Inventors: Andy E.
