Abstract

The system of the preferred embodiments includes a first rotational element, a second rotational element, and a therapeutic source coupled to the rotational elements. The system permits simultaneous attachment to and movement around a surface of tissue, preferably during an ablation procedure (either during lesion creation or between lesion creation events), or during any other suitable procedure. The therapeutic source functions to translate along the path of tissue and deliver therapy as the first and second rotational elements rotate and roll along the path of tissue. The therapeutic source preferably delivers contiguous doses of therapy along the path of tissue. The system is preferably designed for delivering therapy to tissue and, more specifically, for delivering therapy to cardiac tissue. The system, however, may be alternatively used in any suitable environment and for any suitable reason.
