Abstract
An ablation assembly has an advancer mechanism coupled to a proximal end of a driveshaft, and an ablation device, such as a rotatable burr, coupled to a distal end of the driveshaft. The advancer mechanism is moveable from a first position forward along a path of motion, the ablation device being advanced as the advancer mechanism is moved forward. A stop extends into the path of motion of the advancer mechanism by a sufficient amount to stop the forward motion of the advancer mechanism when it contacts the stop. The stop is secured at a location spaced forward from the starting position of the advancer mechanism by a distance equal to the length of a lesion to be ablated.
