Abstract
A treatment system for occluding a hollow anatomical structure comprises a treatment device sized for insertion into a hollow anatomical structure. The treatment device comprises a therapeutic element configured to treat the hollow anatomical structure. The system comprises a sensor configured to sense a first treatment parameter. A controller is in communication with the treatment device and with the sensor. The controller is configured to determine a second treatment parameter based on the first treatment parameter and output the second treatment parameter.
Claims34
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.
A system for treating a blood vessel, the system comprising:
- a treatment device sized for insertion into a peripheral blood vessel, the treatment device having an elongate shaft with a therapeutic element located at or near the distal end of the shaft;
- a controller in communication with the treatment device, the controller having a memory and being configured to:
- (a) establish 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 memory, the known relationship comprising 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;
- (b) determine a value for a first treatment parameter based on the established blood vessel thermal injury value;
- and
- (c) control operation of the treatment device by manipulating the value of a second treatment parameter that has a known functional 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.
