Disaggregation of Revenue. Our revenue is disaggregated based on reporting segment, product category and geographical region. Beginning in the first quarter of 2020, we revised our product categories to more clearly reflect how we sell our products to our customers. We presented historical information under the new revised product categories in a Current Report on Form 8-K, filed with the SEC on April 3, 2020.

We design, develop, manufacture and market medical products for interventional and diagnostic procedures. For financial reporting purposes, we report our operations in two operating segments: cardiovascular and endoscopy. Our cardiovascular segment consists of four product categories: peripheral intervention, cardiac intervention, custom procedural solutions, and OEM. Within these product categories, we sell a variety of products, including cardiology and radiology devices (which assist in diagnosing and treating coronary arterial disease, peripheral vascular disease and other non-vascular diseases), as well as embolotherapeutic, cardiac rhythm management, electrophysiology, critical care, breast cancer localization and guidance, biopsy, and interventional oncology and spine devices. Our endoscopy segment consists of gastroenterology and pulmonology devices which assist in the palliative treatment of expanding esophageal, tracheobronchial and biliary strictures caused by malignant tumors.

The following table presents sales by operating segment disaggregated based on product category and geographic region for the years ended December 31, 2020, 2019 and 2018 (in thousands).
