Patent number: 8728026Abstract: Devices and methods for their use in increasing the aortic valve flow of a stenotic aortic valve are provided. The subject devices include an aortic valve isolation element and an aortic valve flushing element. The aortic valve isolation element is made up of a ventricular side aortic valve occlusion element, coronary ostia occlusion elements and an ascending aorta occlusion element. The aortic valve flushing element is made up of a dissolution fluid introducing element and a fluid removal element. In practicing the subject methods, a stenotic aortic valve is first isolated. Next, the isolated valve is flushed with a dissolution fluid, e.g., an acidic dissolution fluid, for a period of time sufficient for the aortic valve flow of the treated valve to be increased. In certain embodiments, the valve is also contacted with a dissolution fluid attenuating fluid, e.g., a buffer, during the flushing step in order to limit the contact of non-valve tissue with the dissolution fluid.Type: GrantFiled: December 5, 2005Date of Patent: May 20, 2014Assignee: Cordis CorporationInventors: Brent R. Constantz, Peter K. Johansson

Patent number: 8500683Abstract: Catheter systems and methods for their use in enhancing fluid flow through a vascular site occupied by a vascular occlusion are provided. The subject catheter systems include at least an aspiration catheter and at least one of a total occlusion insert catheter and a partial occlusion insert catheter, where the insert catheters are capable of being slidably moved in the lumen of the aspiration catheter. In practicing the subject methods, a surface of the vascular occlusion is flushed with an acidic dissolution fluid using the subject catheter systems for a period of time sufficient for fluid flow through the vascular site to be enhanced, e.g. increased or established. The subject catheter systems and methods find use in the treatment of a variety of different vascular diseases characterized by the presence of calcified vascular occlusions, including peripheral and coronary vascular diseases.Type: GrantFiled: November 7, 2005Date of Patent: August 6, 2013Assignee: Cordis CorporationInventors: Brent R. Constantz, Peter K. Johansson, Erin McGurk

Patent number: 8496620Abstract: Fluid delivery systems capable of introducing first and second fluids into first and second lumens of a multi-lumen catheter are provided. The first and second fluids are generally a dissolution fluid and a dissolution fluid attenuating fluid. Also provided are fluid delivery devices and kits that include the subject systems. The subject fluid delivery systems find use in a variety of different applications, and are particularly suited for use in the chemical ablation of internal vascular lesions.Type: GrantFiled: November 4, 2005Date of Patent: July 30, 2013Assignee: Cordis CorporationInventors: Brent R. Constantz, Peter K. Johansson

Publication number: 20100023056Abstract: Anchors, tethers, knot configurations and other coupling mechanisms used to secure tethers to anchors or other implants are described. The knot configurations described may provide enhanced knot security and/or tensile strength, while also occupying relatively little volume. In some variations, the surfaces of a tether and/or an anchor or other implant may be at least partially coated with one or more agents and/or may be at least partially textured.Type: ApplicationFiled: July 17, 2009Publication date: January 28, 2010Applicant: Guided Delivery Systems Inc.Inventors: Peter K.

Patent number: 7195639Abstract: An intraluminal grafting system having a balloon catheter assembly, a capsule catheter assembly and capsule jacket assembly is used for deploying in the vessel of an animal body a bifurcated graft having a plurality of attachment systems. The deployment catheters contain an ipsilateral capsule assembly, a contralateral capsule assembly and a distal capsule assembly, wherein the attachment systems of the bifurcated graft are disposed within the three capsule assemblies. A removable sheath of the capsule jacket assembly covers the bifurcated graft and capsule assemblies to provide a smooth transition along the length of the deployment catheters. The bifurcated graft is comprised of a main tubular member and two tubular legs, having attachment systems with wall engaging members secured to the superior end of the main tubular member and the inferior ends of the tubular legs. An inflatable membrane configured on the balloon catheter is used to firmly implant the attachment systems within the vessel.Type: GrantFiled: January 23, 2004Date of Patent: March 27, 2007Assignee: Endovascular Technologies, Inc.Inventors: Dinah B. Quiachon, Alec A. Piplani, Richard S. Williams, Steve G. Baker, Peter K. Johansson
