Cannula having reverse flow tip

摘要

A cannula for conducting fluid to a body includes a cannula body having proximal and distal ends and a lumen extending therebetween. The lumen is adapted to receive the fluid flowing therethrough. The cannula also includes a cannula tip, which is coupled to the distal end of the cannula body. The canula tip includes a side wall having a plurality of fluid outlets formed therein. Each fluid outlet is directed toward the proximal end of the cannula body to reverse the flow of fluid exiting the cannula by an obtuse angle from the original direction of flow.
