PERFUSION CANNULA, METHOD AND SYSTEM

摘要

A perfusion cannula [10] for treating a patient. The cannula [10] comprises a hollow tube [12] adapted for insertion into a vessel of the patient and adapted for fluid flow. The tube has a proximal end [16]. The tube has a primary hole [18] disposed in proximity to the proximal end [16] for release of fluid from the tube and at least a first perfusion hole [201] disposed in the tube wall for release of fluid from the tube. The cannula include a widener [24] extending from the outer surface of the tube and effectively extending the outer diameter of the tube.
