Cryospray Ablation of Surgical Resection Specimens To Determine Safety And Histological Effect In The Lung

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the feasibility and general safety in the human airway as well as assess the safety and depth and area of treatment using liquid nitrogen sprayed through a catheter via flexible fiber optic bronchoscopy (FFB) using surgical resection specimens from patients undergoing lobectomy.

Detailed Description
-----------------
The primary endpoints for this study are patient safety and the histological effects of cryospray therapy in lobectomy patients. The proposed study is a single center study to evaluate the safety and treatment effect of sprayed liquid nitrogen through a catheter via FFB using surgical resection specimens from patients undergoing lobectomy.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Device: CryoSpray Ablation System|CSA Medical, Inc. (formerly CryMed Technologies, Inc.) received FDA market clearance for the CSA System (CryoSpray AblationTM System, formally Cryo Ablator System) on April 21, 2006. It is a Class II device intended to be used as a cryosurgical tool for the destruction of unwanted tissue in the field of general surgery, specifically for endoscopic applications (K070893). As defined by the FDA, the CSA System is a cryosurgical unit with a liquid nitrogen cooled cryocatheter and accessories used to destroy tissue during surgical procedures by applying extreme cold|
