Patent number: 8262689Abstract: A self-expanding basket for use in conjunction with an embolic filtering device has a proximal set of struts which are connected to a distal set of struts by a bending region which provides enhanced bending characteristics to the basket. The bending region can be formed by intermediate links which are extremely flexible and bendable to allow the basket to be delivered through tortuous anatomy. The intermediate links are extremely flexible and create a mechanical hinge-like connection between the proximal and distal strut assemblies. The basket thus is capable of substantial bending when being delivered through the patient's vasculature and will bend and conform to the patient's anatomy once positioned for filtering purposes. The intermediate links can also lengthen, when needed, when positioned in a curved vessel in the patient's vasculature, when needed.Type: GrantFiled: September 28, 2001Date of Patent: September 11, 2012Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Gary Schneiderman, Anuja H. Patel, Paul F. Muller, William J. Boyle, Thomas A. Hassing, Thomas H. Majcher

Patent number: 7976456Abstract: A cardiac harness for treating or preventing congestive heart failure is configured to be placed about at least a portion of a patient's heart so as to apply a mild compressive force on the heart. In one embodiment, the cardiac harness comprises a plurality of spaced apart conductive panels arranged so that there is no electrical continuity circumferentially around the harness. In an additional embodiment, a cardiac harness is provided that is insulated so as not to conduct electricity circumferentially about the harness.Type: GrantFiled: December 23, 2008Date of Patent: July 12, 2011Assignee: Paracor Medical, Inc.Inventors: Lilip Lau, James Hong, Steven Meyer, Matthew G. Fishler, Craig Mar, Anuja H. Patel, Sieu Duong

Patent number: 7097651Abstract: A basket for an embolic protection filtering device to be deployed within a body lumen for capturing embolic debris is disclosed. In one embodiment, a strut pattern forming the basket includes V-shaped struts having an internal radius at the apex with a kerf on each strut arm beginning at the radius and extending toward an opposite end of the strut. The apex may have a bulbous shape. In another embodiment, the strut arms of the basket include undulations. Also, the apices may be situated so that one apex is longitudinally staggered from an adjacent apex. The combination of features enables the basket to be crimped to a small profile while distributing stress away from the apices of the V's in the strut pattern.Type: GrantFiled: September 6, 2001Date of Patent: August 29, 2006Assignee: Advanced Cardiovascular Systems, Inc.Inventors: William J. Harrison, Anuja H. Patel

Publication number: 20030158575Abstract: Cold worked nickel-titanium alloys that have linear pseudoelastic behavior without a phase transformation or onset of stress-induced martensite as applied to a medical device having a strut formed body deployed from a sheath is disclosed. In one application, an embolic protection device that employs a linear pseudoelastic nitinol self-expanding strut assembly with a small profile delivery system for use with interventional procedures is disclosed. Linear pseudoelastic nitinol is used in the medical device as distinct from non-linear pseudoelastic (i.e., superelastic) nitinol. The expandable strut assembly is made from a small diameter tubing of cold worked nickel-titanium alloys. The self-expanding struts that deploy the filter element is laser cut from a large diameter cold worked nickel-titanium alloy, then joined to the small diameter tubing.Type: ApplicationFiled: February 12, 2003Publication date: August 21, 2003Inventors: John F. Boylan, William J. Boyle, John E. Papp, Anuja H. Patel
