US Patent:

2007027, Nov 29, 2007

Filed:

Aug 10, 2007

Appl. No.:

11/889294

Inventors:

Mark Johnston - Lancaster PA, US
Jennifer Cartledge - Clemson SC, US

Assignee:

CSA Medical, Inc. - Baltimore MD

International Classification:

A61B 18/02

US Classification:

Abstract:

Disclosed is a cryosurgical catheter which is heated in order to prevent its freezing within the lumen of an endoscope. The catheter is to be used with an endoscope to perform cryoablation on an internal tissue; e.g., the esophagus. Electric conductivity to produce heat employs an electrical conductive coating on the catheter. Also, disclosed is a fitting for use with a catheter comprising both a connection for receiving gas and an electrical connection.
