A method is provided for optically measuring tissue in a medical procedure comprising suctioning a tissue using a suction device, sending optical signals along optical fibers through the suction device; directing the signals from the optical fibers onto the tissue using a beveled surface; receiving optical signals from the tissue in optical fibers via the beveled reflective surface; measuring the received optical signals in a spectrometer or detector; and releasing, resecting or ablating the tissue through the suction device.

Techniques related to temporary setpoint values are disclosed. The techniques may involve causing operation of a fluid delivery device in a closed-loop mode for automatically delivering fluid based on a difference between a first setpoint value and an analyte concentration value during operation of the fluid delivery device in the closed-loop mode. Additionally, the techniques may involve obtaining a second setpoint value. The second setpoint value may be a temporary setpoint value to be used for a period of time to regulate fluid delivery, and the second setpoint value may be greater than the first setpoint value. The techniques may further involve causing operation of the fluid delivery device for automatically reducing fluid delivery for the period of time based on the second setpoint value.

Systems for applying a transcutaneous monitor to a person can include a telescoping assembly, a sensor, and a base with adhesive to couple the sensor to skin. The sensor can be located within the telescoping assembly while the base protrudes from a distal end of the system. The system can be configured to couple the sensor to the base by compressing the telescoping assembly.
