FDA has cleared a CSA Medical 510(k) to expand the use of its truFreeze catheter offerings to include a third spray kit called RapidAV Spray Kit. “The RapidAV catheter has a material property change such that it provides the ability to shorten the time to liquid nitrogen spray by 50%,” the company says. “The shortened time to liquid nitrogen spray decreases treatment time overall as well.”

  
The device is indicated for use as a cryosurgical tool in the fields of dermatology, gynecology, and general surgery, to ablate benign (e.g., Barrett’s Esophagus with high grade dysplasia) and malignant lesions. “The truFreeze system makes it possible to deliver liquid nitrogen inside the body in a way that is far colder than is needed to effectively destroy these tissue types by a factor of greater than two,” the company says.
