A medisensor (or hand scanner, or medpac scanner) was a handheld medical device that could be used to determine a patient's medical condition. Medisensor's were short-ranged devices but could be patched into larger sensor systems to increase their range. They were often included in medpacs. Wilek Nereus used a Medisensor to monitor Luke Skywalker's health after he allegedly ingested a Olabrian trichoid. The BioTech RFX/K Medisensor was a type of medisensor.
