Abstract
A fluid management system receives fluid from a fluid source and delivers the fluid to a medical probe having a first fluid infusion and aspiration circuit and a second fluid infusion and aspiration circuit. The system also transfers fluid from the medical probe to a collection container. A controller operates a first pump and valve assembly to selectively deliver fluid inflow from the fluid source to one of the first fluid infusion and the second fluid infusion and aspiration circuit. The controller further operates a second pump and valve assembly to selectively transfer fluid outflow to the collection container from one of the first fluid infusion and aspiration circuit of the medical probe and the second fluid infusion and aspiration circuit of the medical probe.
Claims23
A fluid management system configured to receive fluid from a fluid source, to deliver fluid to a medical probe having a first fluid infusion and aspiration circuit and a second fluid infusion and aspiration circuit, and to transfer fluid from the medical probe to a collection container, said system comprising:
- a first pump and valve assembly;
- a second pump and valve assembly;
- and
- a controller configured to operate the first pump and valve assembly to selectively provide fluid inflow from the fluid source to one of the first fluid infusion and aspiration circuit of the medical probe and the second fluid infusion and aspiration circuit of the medical probe and to operate the second pump and valve assembly to selectively transfer fluid outflow to the collection container from one of the first fluid infusion and aspiration circuit of the medical probe and the second fluid infusion and aspiration circuit of the medical probe.
An electrosurgical resection method for treating a patient's prostate, said method comprising:
- providing a fluid management wherein a pump system circulates fluid in a first path through a transurethral device to allow endoscopic viewing within the prostate urethra;
- providing a fluid management wherein a pump system circulates fluid in a second path to through a transurethral device to assist in electrosurgical tissue resection.
An electrosurgical method for resecting a patient's tissue, said method comprising:
- establishing an inflow of fluid using a first pump;
- establishing an outflow of fluid using a second pump;
- directing the inflow of fluid from the first pump both to a viewing scope in a patient lumen or body cavity and to a resection tool engaged with target tissue;
- and
- collecting the outflow of fluid from both the viewing scope in the patient lumen or body cavity and from the resection tool engaged with the target tissue using the second pump.
