Abstract
A catheter for administering a substance into a patient's tissue including a number of pressure sensors for detecting changes in the shape of the catheter or s a backflow along the surface of the catheter. In response to the pressure distribution profile collected along the surface or length of the catheter, the physician may simulate or adapt the substance administration plan to accommodate the actual position of the catheter or the backflow along the surface of the catheter.
Claims12
A method for administering a substance into a patient's tissue, comprising:
- providing a catheter having an elongated catheter body that surrounds a lumen, said catheter body including a plurality of pressure sensors in the material of the catheter body,
- detecting a pressure distribution over a portion of the catheter via the plurality of pressure sensors, and
- determining the presence and/or extent of a backflow along the catheter body based on the detected pressure distribution.
