Abstract: Implants or systems of implants and methods apply a selected force vector or a selected combination of force vectors within or across the left atrium, which allow mitral valve leaflets to better coapt. The implants or systems of implants and methods make possible rapid deployment, facile endovascular delivery, and full intra-atrial retrievability. The implants or systems of implants and methods also make use of strong fluoroscopic landmarks. The implants or systems of implants and methods make use of an adjustable implant and a fixed length implant. The implants or systems of implants and methods may also utilize a bridge stop to secure the implant, and the methods of implantation employ various tools.

Abstract: Devices, systems and methods supplement, repair, or replace a native heart valve. The devices, systems, and methods employ an implant that, in use, extends adjacent a valve annulus. The implant includes a mobile neoleaflet element that occupies the space of at least a portion of one native valve leaflet. The implant mimics the one-way valve function of a native leaflet, to resist or prevent retrograde flow. The implant restores normal coaptation of the leaflets to resist retrograde flow, thereby resisting eversion and/or prolapse, which, in turn, reduces regurgitation.

Abstract: Devices, systems, and methods employ an implant that is sized and configured to attach in, on, or near the annulus of a dysfunctional heart valve. In use, the implant extends either across the minor axis of the annulus, or across the major axis of the annulus, or both. The implant restores to the heart valve annulus and leaflets a more functional anatomic shape and tension. The more functional anatomic shape and tension are conducive to coaptation of the leaflets, which, in turn, reduces retrograde flow or regurgitation.

Abstract: The devices of the present invention form a platform, or scaffold for the precise delivery of various forms of energy for treatment of atrial fibrilation. Additionally, the devices of the present invention form a scaffold for the precise delivery of fluids to surrounding tissues. The use of additional energy sources can improve the delivery of various fluids into the surrounding tissue.

Abstract: The present invention is a group of medical devices designed to improve heart valve function. The medical devices may be used individually, or in combination to supplement damaged valves, replace damaged valves, or improve damaged valves function. The medical devices include leaflet retainers, a neo-annulus, neo-leaflet, and a framework. In addition, the present invention is novel methods for surgically treating heart valves.

Abstract: Devices, systems, and methods employ an implant that is sized and configured to attach to the annulus of a dysfunctional heart valve annulus. In use, the implant extends across the major axis of the annulus above and/or along the valve annulus. The implant reshapes the major axis dimension and/or other surrounding anatomic structures. The implant restores to the heart valve annulus and leaflets a more functional anatomic shape and tension. The more functional anatomic shape and tension are conducive to coaptation of the leaflets, which, in turn, reduces retrograde flow or regurgitation. The implant improves function to the valve, without surgically cinching, resecting, and/or fixing in position large portions of a dilated annulus, or without the surgical fixation of ring-like structures.

Abstract: Devices, systems and methods retain a native heart valve leaflet to prevent retrograde flow. The devices, systems, and methods employ an implant that, in use, rests adjacent a valve annulus and includes a retaining structure that is sized and shaped to overlay at least a portion of one or more native valve leaflets. The retaining structure retains the leaflet or leaflets it overlays, to resist leaflet eversion and/or prolapse. In this way, the implant prevents or reduces regurgitation. The implant does not interfere significantly with the opening of and blood flow through the leaflets during periods of antegrade flow.

Abstract: A bifurcated stent comprises a first stent section and a second stent section. Each stent section is expandable from a predeployed state to a deployed state independently from one another. The second stent section having an end engaged to a receiving region of the first stent section. In the deployed state the first stent section defines a primary flow path and the second stent section defines a secondary flow path in fluid communication with the first flow path. At least a portion of one or both the first stent section and second stent section is constructed from a wire member.

Abstract: The present invention relates, generally, to thermography catheters and, more particularly, to thermography catheters which use flex circuit technology to create the connections and thermocouples used to detect hot spots (areas with high metabolic activity) of the atherosclerotic plaque, vascular lesions, and aneurysms in human vessels.

Abstract: Interventional tools are described that are suitable for measuring the temperature of or temperature variations in a vessel wall in the body of a patient and thereafter treating vulnerable plaque that is identified during the thermal mapping. The described interventional tools all include one or more thermal sensors that are suitable for detecting an indication of the temperature of or temperature variations in walls of a vessel the tool is inserted into. These sensors may be used to facilitate the detection of vulnerable plaque within the vessel. In one aspect, the interventional tool includes a stent delivery device that is suitable for delivering a stent to a selected segment of a vessel the interventional tool is inserted into. In an alternative aspect the interventional tool includes a deployment lumen. The deployment lumen is sized suitably for receiving a stent delivery catheter therethrough.

Abstract: A variety of improved thermal mapping catheters are disclosed which are capable of sensing and mapping thermal variations within body vessels. In embodiments directed at vascular applications, the catheters are capable of detecting temperature variations in atherosclerotic plaque, on the atherosclerotic plaque surface, and on the arterial wall of aneurysms and other vascular lesions of the human vasculature. In one aspect of the invention, a combined thermal mapping and drug delivery catheter is provided. In this embodiment a plurality of thermal sensors are combined with at least one infusion port suitable for delivering therapeutic agents into a vessel. In some embodiments, at least some of the infusion ports are located between adjacent thermal sensors. The described catheters may be used in a variety of new applications and medical diagnostic and treatment techniques.
