Abstract
A cannula system having an internally slidable elongate tubular member frictionally anchored within a trocar, and optionally including a flange which acts as a positive stop against the trocar, that can be deployed for various treatments, including aortic cannulation during cardiopulmonary bypass, for example during CABG surgery. The tubular member has a proximal end, a lumen, and a flexible distal end which carries a preformed angled configuration relative to its proximal region and is bendable to a substantially linear configuration. The rigid trocar maintains the cannula in a substantially linear configuration. When the cannula is advanced through the lumen beyond the distal end of the trocar, the tubular member regains its angled configuration. Methods for using the devices herein are also disclosed.
