Appl. No.:

13/784596

Inventors:

Ron Burr - Parkton MD, US
Rafael Cordero - Bedford MA, US
Marc Davidson - Andover MA, US
Wendelin Cherise Maners - Hermosa Beach CA, US
Petrilli Janel - Pittsburgh PA, US

Assignee:

CSA MEDICAL, INC. - Baltimore MD

International Classification:

A61B 18/02

US Classification:

606 21

Abstract:

A cryosurgery system for application of medical-grade liquid nitrogen to a treatment area via a small, low pressure, open tipped catheter. The system includes a console, including a touch panel computer, a cryogen module , a suction module and an electronics module, and a disposable spray kit. Features include optional low cryogen flow setting to reduce the cryogen flow rate by 50%, improved cryogen flow consistency reducing pressure pulses and peaks, an integrated suction pump for improved consistency and self-checks, specified vent tube areas and corresponding maximum expected pressures during cryospray procedure; optional pressure sensing capability to monitor pressure during a treatment, and novel catheter designs of multilayer and flexible construction providing a variety of spray patterns.
