发明名称 COATED CANNULA WITH PROTECTIVE TIP FOR INSERTION INTO A PATIENT
摘要 The present application is directed to a cannula for insertion into a patient. The cannula includes a first distal section and a second proximal section with a hollow interior extending through each. The first section is positioned distally of the second section and includes a larger outer diameter. A coating is applied to the second section. An outer diameter of the coating is smaller than or equal to the outer diameter of the first section. This design prevents the coating from detaching from the second section during insertion of the cannula into the patient. In one embodiment, the cannula acts as a guide for inserting the coating into the patient and the first section protects the leading edge of the coating.
