A system for treating a gastrointestinal tract may include a device configured to measure electrical activity at a plurality of locations within a gastrointestinal tract of a patient, a controller configured to compare the measured activity from the plurality of locations to a database of electrical activity corresponding to one or more gastric events, abnormalities, or dysrhythmias. The controller may be configured to determine one or more treatment locations based on the comparison, and cause the device to deliver therapy to the one or more treatment locations.

A method and system are provided for detecting pancreatic trauma in a trauma patient during a surgical operation. The method includes positioning a detection device in contact with the patient's pancreas, applying a chemical indicator to the detection device after removing the detection device from the patient, and detecting a chemical reaction on the detection device that is indicative of the pancreas releasing an enzyme as a result of pancreatic trauma.

A gastrojejunostomy tube is used when a patient's stomach must be bypassed, with nutrients and/or medication being delivered directly to the jejunum. In this situation, the stomach commonly fills with stomach acid and digestive enzymes, which may cause vomiting, acid reflux or other esophageal problems. The gastrojejunostomy drainage bag is provided to allow the contents of the stomach to be drained through the gastrojejunostomy tube, rather than building up within the patient's stomach. The gastrojejunostomy drainage bag includes a receptacle having a lower portion and an upper stem portion, the upper stem portion terminating in a port adapted for connection to the gastrojejunostomy tube. Preferably, a lower port is formed through the lower portion, allowing the contents of the gastrojejunostomy drainage bag to be selectively emptied. A method of releasing gas or trapped air from the stomach is also disclosed.

A method for identifying a ureter during a medical procedure, the method comprising: providing an electrical stimulator comprising: a shaft having at least one electrode; and a power supply connected to the at least one electrode for providing an electrical signal to the at least one electrode; advancing the shaft so that the at least one electrode contacts tissue; operating the power supply so that the electrical signal is applied to the tissue; and visually observing the tissue to determine the presence of a ureter in the tissue.

A medical capsule with a sensor device comprising a light emitting element and a light detecting element with the sensor device being adapted to detect the presence or non-presence of blood and/or Biliverdin based on the light absorption properties of blood and Biliverdin. The capsule is provided with a casing forming a gap at its outer surface. The light emitting element alternatively emits violet light of a wavelength of about 380-450 nm, green light of a wavelength of about 530-580 nm, and red light of a wavelength of about 620-750 nm, whereas the light detecting element generates a separate sensor signal associated with measured light intensities I.sub.violet, I.sub.green, and I.sub.red of at least each of the wavelength ranges of the light from the light emitting element. By evaluating a quotient I.sub.red/I.sub.green, false-positive detection of blood can be avoided. The present disclosure also relates to a calibration method for said medical capsule.

Embodiments include an ingestible capsule being configured, in response to identification of an excretion marker from on-board sensor hardware, to determine occurrence of an excretion event, and in response to determining occurrence of the excretion event to modify one or more settings of the wireless data transmitter to start, restart, increase transmission power of, or increase a rate of, wireless transmission of the data transmission payload away from the ingestible capsule by a wireless data transmitter.
