Csa Medical, Inc. CSA


At CSA Medical®, we aim to be the leading global provider of innovative spray cryotherapy medical device solutions that:

  • improve patient outcomes;
  • simplify procedures; and
  • reduce the cost of healthcare.

Our truFreeze® spray cryotherapy technology uses extremely cold liquid nitrogen (-196° C) to provide targeted, touchless ablation of unwanted tissue inside the body under direct visualization.

The truFreeze System can be used in general surgery with or without an endoscope (viewing the esophagus or other lumen with a camera).
