    摘要： A catheter adapted for mapping and ablating epicardial tissue from the pericardial cavity includes a catheter body and an electrode assembly that has a tip section and a loop member lying generally within a plane, wherein the tip section includes an ablation electrode exposed on one side of the loop member and an insulation member exposed on an opposite side of the loop member. The catheter also includes a intermediate section between the catheter body and the electrode assembly, wherein the intermediate deflects the loop member and the tip section bi-directionally within the same plane. So arranged, the catheter can be safely maneuvered in the pericardial sac and swept in a side to side motion over the epicardium with the ablation electrode reliably facing and making contact with the epicardium. The tip section can include a balloon that is inflatable to push away surrounding pericardial tissue. The catheter may further include an injection needle whose distal end can extend outside of the tip section to puncture epicardial tissue. A lumen in the injection needle allows for delivery to agents directly to the punctured tissue and thermocouple wires can be carried in the lumen for temperature sensing at the treatment site.

    摘要： Disclosed is an apparatus and method for communicating over an electrically conductive line having a plurality of power line phases between a first device having a single receiver and plurality of distal devices. The power line phases are adapted to deliver an alternating electrical current. Each of the distal devices are adapted to communicate with the first device over a single phase through a modulated carrier signal at a communication frequency. The apparatus comprises a plurality of unique coupling phases for coupling to a corresponding power line phase adapted to receive a frequency band having the modulated carrier signal from each of the plurality of power line phases and a selective coupling circuit between each of the plurality of coupling phases. The method comprises receiving the modulated carrier signal from each of the plurality of power line phases, attenuating the frequency band from being received by another of said unique coupling phases.

    摘要： A catheter includes a cryoablation tip with an electrically-driven ablation assembly for heating tissue. The cryoablation tip may be implemented with a cooling chamber through which a controllably injected coolant circulates to lower the tip temperature, and having an RF electrode at its distal end. The RF electrode may be operated to warm cryogenically-cooled tissue, or the coolant may be controlled to conductively cool the tissue in coordination with an RF treatment regimen, allowing greater versatility of operation and enhancing the lesion size, speed or placement of multi-lesion treatment or single lesion re-treatment cycles. In one embodiment a microwave energy source operates at a frequency to extend beyond the thermal conduction depth, or to penetrate the cryogenic ice ball and be absorbed in tissue beyond an ice boundary, thus extending the depth and/or width of a single treatment locus. In another embodiment, the cooling and the application of RF energy are both controlled to position the ablation region away from the surface contacted by the electrode, for example to leave surface tissue unharmed while ablating at depth or to provide an ablation band of greater uniformity with increasing depth. The driver or RF energy source may supply microwave energy at a frequency effective to penetrate the ice ball which develops on a cryocatheter, and different frequencies may be selected for preferential absorption in a layer of defined thickness at depth in the nearby tissue. The catheter may operate between 70 and minus 70 degrees Celsius for different tissue applications, such as angioplasty, cardiac ablation and tissue remodeling, and may preset the temperature of the tip or adjacent tissue, and otherwise overlay or delay the two different profiles to tailor the shape or position where ablation occurs or to speed up a treatment cycle.
