Systems and methods for intracavitary temperature measurement and monitoring

A system for intracavitary tissue measurement and monitoring, the system comprising:

• an introducer device configured to be positioned adjacent to an intracavitary tissue, the introducer device comprising:
• a catheter shaft having a distal end, a longitudinal axis, and a lumen extending therethrough, the catheter shaft having an opening at the distal end along the longitudinal axis such that at least a portion of the lumen is exposed;
• a circuit board having an array of infrared sensors disposed thereon, the circuit board disposed within the lumen of the catheter shaft at least partially in the opening at the distal end, the array of infrared sensors each having circuitry configured to generate a signal indicative of temperature of the intracavitary tissue;
• and
• an expandable structure formed from an infrared transmissive material and disposed along the longitudinal axis on the distal end of the catheter shaft to surround the array of infrared sensors and to provide a field of view through the opening such that the opening is in fluid communication with an interior of the expandable structure;
• and
• a non-transitory computer readable media having instructions stored thereon, wherein the instructions, when executed by a processor operatively coupled to the circuit board, cause a graphical user interface to display information indicative of temperature of the intracavitary tissue based on the signal from the array of infrared sensors.
