Segment Reporting [Abstract]

Segment Reporting

Segment Reporting. We report our operations in two operating segments: cardiovascular and endoscopy. Our cardiovascular segment consists of cardiology and radiology medical device products which assist in diagnosing and treating coronary artery disease, peripheral vascular disease and other non-vascular diseases and includes our embolotherapeutic products. Our endoscopy segment consists of gastroenterology and pulmonary medical device products which assist in the palliative treatment of expanding esophageal, tracheobronchial and biliary strictures caused by malignant tumors. We evaluate the performance of our operating segments based on operating income (loss). Financial information relating to our reportable operating segments and reconciliations to the consolidated totals is as follows (in thousands):
