Abstract: Cryotreatment devices and methods of ablating tissue within the body are disclosed. A cryotreatment device in accordance with an exemplary embodiment of the present invention includes an elongated member having one or more needle-like ablation tips configured to induce necrosis at a target site within the heart. A cooling fluid such as a cryogen may be injected through a lumen extending into the distal portion of the device. The ablation tips can be configured to pierce and ablate surrounding tissue, blocking electrical stimuli that can cause fibrillations or other arrhythmias of the heart. The device may also include means for controlling the transmural depth at which the ablation tips are inserted into the cardiac tissue. Methods of forming a contiguous line of conduction block in accordance with the present invention are also disclosed.

Abstract: Devices and methods for cooling vessel walls to inhibit restenosis in conjunction with medical procedures such as coronary artery angioplasty. One catheter device includes a distal tube region having coolant delivery holes radially and longitudinally distributed along the distal region. In some devices, holes spray coolant directly onto the vessel walls. In other embodiments, a balloon or envelope is interposed between the coolant and the vessel walls and the coolant returned out of the catheter through a coolant return lumen. Some direct spray devices include an occlusion device to restrict blood flow past the region being cooled. Pressure, temperature, and ultrasonic probes are included in some cooling catheters. Some cooling catheters are coiled perfusion catheters supporting longer cooling periods by allowing perfusing blood flow simultaneously with vessel wall cooling.

Abstract: A filter system, comprising an elongate filter body defining a lumen and having a proximal end and a distal end. A valve can be provided defining a lumen and having a reversibly sealable opening for unidirectional flow of a fluid through the lumen. The valve can be adjoined proximal the distal end of the elongate filter body, wherein the elongate filter body filters the unidirectional flow of the fluid passing through the lumen of the valve and the lumen of the elongate filter body.

Abstract: Some embodiments of pacing systems employ wireless electrode assemblies to provide pacing therapy. The wireless electrode assemblies may wirelessly receive energy via an inductive coupling so as to provide electrical stimulation to the surrounding heart tissue. In certain embodiments, the wireless electrode assembly may include one or more biased tines that shift from a first position to a second position to secure the wireless electrode assembly into the inner wall of the heart chamber.

Abstract: Various configurations of systems that employ leadless electrodes to provide pacing therapy are provided. In one example, a system that provides multiple sites for pacing of myocardium of a heart includes wireless pacing electrodes that are implantable at sites proximate the myocardium using a percutaneous, transluminal, catheter delivery system. Each of the electrodes contains a source of electrical energy for pacing the myocardium and is adapted to receive electromagnetic energy from a source outside the myocardium. The system also includes a source adapted for placement outside the myocardium and that uses locally measured electrocardiograms to synchronize pacing of the heart by sending electromagnetic commands to the electrodes to pace the myocardium surrounding the electrodes. Also disclosed is various configurations of such systems, wireless electrode assemblies, and delivery catheters for delivering and implanting the electrode assemblies.
