Patent ID: 8321019

Claim:
A method of preventing a heating coil of a treatment device from powering up outside anatomy of a biological entity, the method comprising: sensing a temperature on a heating coil of a blood vessel treatment device, the heating coil having at least one insulated layer configured to prevent electrical conduction into tissue of a blood vessel to be treated while at the same time allowing heat conduction into that same tissue of the blood vessel; determining whether said heating coil is disposed within the anatomy of the biological entity by determining whether said temperature satisfies a required initial temperature condition, the required initial temperature condition comprising a temperature that is significantly above an expected ambient room temperature; receiving a request to initiate power delivery to said heating coil of said blood vessel treatment device; if said temperature does not satisfy said required initial temperature condition, performing a safety procedure to interrupt a normal power-up process for the heating coil by preventing the heating coil of the treatment device from powering up outside the anatomy of the biological entity having the blood vessel to be treated.
