Micro-remote gastrointestinal physiological measurement device
First Claim
1. An instrument for inserting and positioning a sensor-transmitter assembly in a body of a subject, the instrument comprising:
- an insertion section insertable through the nasal-gastric segment of the gastrointestinal tract of a subject;
a deployment section disposed at a distal end portion of the insertion section, the deployment section having therein a lumen shaped receptacle retaining a sensor;
an elongate push rod extending through and slidable in the insertion section to push the sensor out of the lumen shaped receptacle in the gastrointestinal tract of the subject; and
a removable outer sleeve encircling the insertion section and containing a tether connected to the sensor between at least the insertion section and the removable outer sleeve.

Abstract
A physiological sensor-transmitter assembly for measuring a physiological property at an internal body location of a subject over time is described. An instrument for inserting the assembly in the subject and a method of monitoring a physiological property measured at the internal body location over time are also described. The assembly includes a sensor and a transmitter adapted to transmit information from the sensor in a non-wired fashion to a receiver. The assembly also includes an anchor adapted to attach to an externally accessible portion of a subject and a tether that connects the sensor and the anchor to maintain a position of the sensor within the gastrointestinal tract of the subject.
