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

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.
