Abstract:
A device for creating lesions in body tissues includes a support element (98) having an electromagnetic energy emitting region (104). When caused to emit energy, the region (104) creates a single continuous lesion that is long and thin.
Abstract:
A device for creating the lesions in body tissue includes a support element having an electromagnetic energy emitting region. When caused to emit electromagnetic energy, the region creates a single continuous lesion that is long and thin, having a lengththat is substantially greater than its width.
Abstract:
Systems and associated methods form larger and deeper lesion patterns by shaping a support body with multiple electrodes (30) in ways that increase the density of the electrodes (30) per given tissue area. The support body (12) can carry either elongated, continuous electrodes (80) or arrays of non-contiguous, segmented electrodes (30).
Abstract:
Systems and associated methods position arrays of multiple emitters of ablating energy (30) in straight or curvilinear positions in contact with tissue to form elongated lesion patterns (200)-(206). The elongated lesion patterns can be continuous (200, 204) or interrupted (202, 206), depending upon the orientation of the energy emitters.
Abstract:
A device for ablating tissue within the body has an element (224) with an energy emitting region helically wound about and along the axis of the element. The element emits energy to create a lesion in body tissue. A sheath (240) of a non-energy emitting material is movable over the region to adjust the impedance of the region.
