Steerable and shapable catheter employing fluid force

摘要

A catheter employing fluid force to steer and/or shape the catheter. In one particular implementation, the catheter includes at least one actuating lumen operably associated with the shaft of the catheter. The at least one actuating lumen is in fluid communication with a valve or other fluid control means at its proximal end. The at least one actuating lumen extends along the length of the catheter shaft and terminates at some point along the length of the shaft. Upon introduction of fluid into the actuating lumen, the fluid creates a force which causes the catheter to bend. As such, fluid may be used to steer and/or shape the catheter.
