Abstract: A balloon catheter (100), suitable for delivery of a balloon to the stomach via application by the nose, the balloon catheter comprising a catheter (2) and one or more inflatable balloons (1) fixedly attached to the catheter. The balloons have an outer diameter from 4 to 7 cm, are made of a relatively hard material (e.g. durometer 70 to 100 shore A), and have an effective length of 7 to 18 cm or a total inner volume of 90 to 330 ml, when inflated by 0.2 psi. A system comprising the balloon catheter, and a pressure sensor for measuring a pressure of a fluid inside the balloon, and optionally a fluid pump for inflating and/or deflating the balloon, and a control unit for reading the pressure sensor and optionally for controlling the fluid pump.

Abstract: A system (100) for artificially feeding a patient, comprising: a pressure sensor (114) fluidly connectable to an inflatable balloon (B) via a first lumen of a balloon catheter (130); a controller (110) operatively connected to the pressure sensor (114) for obtaining the measured pressure values; a food pump (112) fluidly connectable to a second lumen of the balloon catheter having at least one opening (132) for providing food; the controller (110) operatively connected to the food pump (112) for driving the food pump at a configurable flow rate; wherein the controller (110) contains computer executable instructions comprising: first code fragments for performing a first algorithm (1300) for extracting gastric motility information from the measured pressure values, and second code fragments for performing a second algorithm for dynamically adjusting (708) said flow rate based on said extracted gastric motility information.
