    摘要: Devices and a method are provided to assist a surgeon in ablating conduction paths in tissue, such as a heart. A device can be configured to operate as a template that adheres to the tissue surface, and allows the surgeon to more easily sever the conduction path to form a lesion in a desired location. In particular, the template can be used to guide the surgeon's use of a surgical instrument along a desired ablation path. In some case, the template may incorporate hardware that structurally supports the instrument for travel along the ablation path. A surgical instrument such as an ablation probe, e.g., radio frequency, laser, ultrasonic, microwave, thermal, chemical, mechanical, or cryogenic ablation probe, may be used to sever the conduction paths. Measurements made substantially contemporaneously with the conduction path ablation operation may be used to evaluate whether the desired degree of ablation has been achieved. The device may also incorporate feedback to compare the desired degree of conduction path ablation with the measured degree, and may deactivate the surgical instrument when the desired degree has been achieved. In some cases, the template device can be configured to provide local stabilization of organ tissue, particularly for a moving organ such as a beating heart. In other cases, the template device may provide little or no stabilization, but provide a guide structure for placement of the ablation probe in the same frame of motion as the moving tissue. Also, for some applications, the template device may be arranged to facilitate application of other therapeutic devices, such as diagnostic probes, pacing leads, and drug delivery devices, to the surface of a moving organ.

    摘要: Devices and methods of manipulating and stabilizing organ tissue, such as heart tissue. The devices, which are of varying sizes, shapes and conformations, generally include a seal member having a chamber with a wall and a skirt-like member that extends outward from the chamber wall for contact with a surface of an organ. The skirt-like member is substantially compliant and tacky, thereby promoting adhesion with the organ surface. Adherence of the device to the tissue may be enhance by the mechanical or hydraulic application of vacuum pressure. The methods describe steps for manipulating, including moving, lifting, immobilizing, turning and reorienting, organ tissues. Additional methods describe steps for manipulating the heart.

    摘要: An electrosurgery medical device is enhanced with unique solution-assistance, and comprises, in combination, co-operating device jaws including jaw portions for manipulating tissue, and a plurality of solution infusion openings defined and spaced along each of the jaw portions, for receiving electrolytic solution and infusing the solution onto and into tissue to be manipulated, along said jaw portions. As preferred, the device further comprises at least one, and most preferably, many, longitudinal groove(s) along at least one and most preferably, both, of the jaw portions, with the solution infusion openings located in the groove or grooves. The solution is energized with RF energy and contributes to the functions and beneficial effects of the instrument. The solution exits the openings in the grooves at sufficient flow rates to separate substantially all the operative surfaces of the device from tissue, thereby substantially completely preventing adherence between the operative surfaces and tissue. The solution is further energized to a range of energy densities such that tissues to be affected are sealed against flow of blood, lymphatic fluids, air, and other bodily fluids and gases.
