Patent ID: 8702695

Claim:
An ablation device comprising: an ablation element comprising a first end and a second end; and a support structure adapted to support the ablation element within an alimentary tract of a patient, the support structure comprising a longitudinal support with a longitudinal axis, the ablation element being positioned on a surface of the longitudinal support parallel to the longitudinal axis of the longitudinal support, and a rotational support, the rotational support comprising: a base with a connecting element to connect the longitudinal support to an endoscope and a pin about which the longitudinal support is arranged such that it can rotate through an operative range of motion with respect to the longitudinal support's longitudinal axis, wherein, throughout the operative range of motion, a line orthogonal to the longitudinal axis of the longitudinal support and passing through the pin intersects the ablation element between the first and second end; and a movement resister configured to resist rotation of the longitudinal support.
