Publication number: 20070276429Abstract: 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: ApplicationFiled: June 26, 2007Publication date: November 29, 2007Applicant: ADVANCED CARDIOVASCULAR SYSTEMS, INC.Inventors: Benjamin Huter, John Papp, Anuja Patel, John Whitfield

Patent number: 7282024Abstract: A cardiac harness for treating a patient's heart includes elastic rows connected by a connector assembly. The connector assembly can have a specific pattern, or can be formed of elongated elastic material connecting all of the apices of adjacent rows. The connectors maintain proper spacing between rows or rings on the harness and provide longitudinal stability.Type: GrantFiled: January 10, 2005Date of Patent: October 16, 2007Assignee: Paracor Medical, Inc.Inventors: Lilip Lau, Matthew Fishler, Craig Mar, Steven Meyer, Anuja Patel

Patent number: 7276021Abstract: A method and apparatus for treating heart failure is configured to be placed about at least a portion of a patient's heart to apply a mild compressive force on the heart over a range of elastic deformation of the apparatus. The apparatus can be shifted to second range of deformation. In some embodiments, the apparatus is shifted to the second range of deformation by application of a stimulus or alteration of environmental conditions beyond a threshold level.Type: GrantFiled: October 31, 2002Date of Patent: October 2, 2007Assignee: Paracor Medical, Inc.Inventors: Lilip Lau, Anuja Patel

Patent number: 7097440Abstract: 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 be pre-formed for expansion 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, and to be foreshortened to enable insertion thereof through confined spaces. The system, in another embodiment thereof, enables expandable material to be formed into an expandable configuration of an embolic protection device for capturing embolic material, which is capable of sealing off the inner surface of the blood vessel.Type: GrantFiled: September 30, 2003Date of Patent: August 29, 2006Assignee: Advanced Cardiovascular Systems, Inc.Inventors: John E.

Publication number: 20050090844Abstract: A high fatigue life superelastic nickel-titanium (nitinol) wire, ribbon, sheet, tubing, or the like is disclosed. The nitinol has a 54.5 to 57.0 weight percent nickel with a balance of titanium composition and has less than 30 percent cold work as a final step after a full anneal and before shape setting heat treatment. Through a rotational beam fatigue test, fatigue life improvement of 37 percent has been observed.Type: ApplicationFiled: October 27, 2003Publication date: April 28, 2005Inventors: Anuja Patel, Jianhau Yang

Patent number: 6814749Abstract: Stent designs for use in peripheral vessels, such as the carotid 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 are generally serpentine wave pattern transverse to the longitudinal axis between alternating valley portion and peak portions, the valley portion including alternating double-curved portions and U-shaped 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 U-shaped portions to connect the cylindrical element to the other adjacent cylindrical element. The designs include an eight crown and six crown stent which exhibit flexibility and sufficient radial strength to support the vessel.Type: GrantFiled: January 16, 2003Date of Patent: November 9, 2004Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Daniel L.
