Patent abstract
A catheter terminates at a tip that includes an array of pressure sensors. The sensors are responsive to detect and alert the user to variations of pressure that indicate the tip is either encountering an obstruction or constriction of smaller diameter than the catheter, as well as to guide the catheter through the conduit into which it is being inserted.
