Patent ID: 8636729

Claim:
A blood vessel therapy system comprising: an energy application device comprising an electrically insulated heating coil suitable for insertion into a hollow anatomical structure, the electrically insulated heating coil configured to prevent electrical contact and electrical conduction with tissue and configured to engage a blood vessel for heat conduction with tissue; a power source in communication with said energy application device, said power source comprising a processor and program instructions executable by said processor such that said power source is operable to: (a) deliver power to said heating coil during a first power delivery phase; (b) measure time elapsing during power delivery; (c) assess performance of said therapy system during said first power delivery phase; (d) if said performance of said therapy system during said first power delivery phase is satisfactory, deliver a decreasing amount of power to said heating coil during a second power delivery phase; and (e) cease power delivery in preparation for movement within the blood vessel to a new treatment segment in the blood vessel; the electrically insulated heating coil being elongate and configured for discrete segmental movement within the blood vessel; and the power source configured to receive an input from a user and further operable to: (f) deliver power to said heating coil during a third power delivery phase upon input from the user, the third power delivery phase configured to be after movement of the therapy system within the blood vessel; and (g) if said operation of said heating coil during or after said third power delivery phase is acceptable, deliver power to said heating coil after said third power delivery phase during a fourth power delivery phase.
