    摘要: Devices, systems and methods are provided for deployment of one or more functional devices, such as therapeutic or diagnostic medical devices, or positioning devices, at various locations relative to a defined operative path. The devices, systems, and methods can include a guide system and a positioning element. The guide system defines the operative path when deployed within a patient's body. The positioning element cooperates with the guide system to define one or more positions relative the defined operative path from which the one or more functional devices are deployed. The present inventions allow for the accurate and reliable placement of the one or more functional devices at the one or more positions relative the operative path. In one embodiment, the functional device is an ablation device adapted to ablate cardiac tissue for the treatment of cardiac arrhythmias, such as atrial fibrillation.

    摘要: An adjustable surgical clamp including one or more ablation elements creates a circular lesion in a first operating mode and a linear lesion in a second operating mode. A “box” lesion surrounding all four pulmonary veins may be formed by using the clamp to create two complimentary C-shaped lesions about pairs of the veins. A thermochromic liquid crystal strip that changes color at a tissue-ablating threshold temperature may be mounted on the surgical clamp to monitor temperature of the ablated tissue. Two microwave antennae may be positioned on the jaws of the clamp relative to each other to produce a combined substantially uniform field of tissue-ablating energy between the jaws.
