Patent ID: 7842076

Claim:
A method of treating a hollow anatomical structure, comprising: employing a treatment device sized for insertion into a peripheral blood vessel and having a therapeutic element and a sensor, the treatment device being configured for connection to a controller for communication with the treatment device and with the sensor; and in the controller, (a) providing a processor; (b) establishing a blood vessel thermal injury value between a minimum thermal injury value capable of effecting an efficacious treatment and a maximum thermal injury value capable of effecting a safe treatment, the blood vessel thermal injury value related to at least two treatment parameters according to a known relationship that is recorded in the processor, the known relationship comprising a first series of distinct values for the first parameter that each have a corresponding specific value in a series of values for the second parameter; (c) determining a value for a first treatment parameter based on the established blood vessel thermal injury value; and (d) controlling operation of the treatment device by manipulating the value of a second treatment parameter that has the known relationship to the first treatment parameter, in order to achieve the determined first treatment parameter and thereby achieve the blood vessel thermal injury value that has been established for safely and efficaciously treating the blood vessel.
