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 embolotherapeutic, cardiac rhythm management ("CRM"), electrophysiology ("EP"), critical care, interventional oncology and spine devices, and our Cianna Medical product line. Our endoscopy segment focuses on the gastroenterology, pulmonary and thoracic surgery specialties, with a portfolio consisting primarily of stents, dilation balloons, certain inflation devices, guide wires, and other disposable products, as well as the products related to our distribution agreement with NinePoint Medical Inc. ("NinePoint Medical"). We evaluate the performance of our operating segments based on net sales and operating income.
