Abstract
Methods and systems for determining whether a catheter malfunction is present in a catheter by analyzing changes in the pressure of fluids being pumped through the delivery lumen of the catheter. The pressure changes that may be monitored may include, e.g., the peak pressure within the catheter and/or the pressure decay profile. The catheter malfunctions that may be determined using the methods and systems of the invention may include, e.g., leaks, blockages, the presence of gas bubbles, etc.
