Catheters generally follow an existing portal into or within the body, such as the urethra, veins, arteries, etc.Cannulas are tubes with a trocar at the front (read sharp front end), used to create a portal into the body, often for drainage. The difference is a cannula is not neccessarily going to be used to follow an existing channel. as would a catheter.
Note that nasal cannulas used in breathing appartus and oxygen delivery are named because of the shape; they aren't used to pierce as most cannulas would.
