ABSTRACT:
The invention provides a devices, methods and systems to measure and record uterine tissue environment components such as pH during the course of uterine artery occlusion. The uterus becomes ischemic due to the occlusion thereof, and its pH drops sharply within minutes of uterine artery occlusion and remains relatively low for a period of time. The return of normal pH is an indicator of return of blood to the ischemic tissue. In use, a catheter with a pH measuring tip is advanced through the patient's vaginal canal and into the patient's uterine cavity until the pH measuring active electrode on the distal end of the catheter contacts or penetrates the uterine fundus. The active electrode detects the pH and a signal representing pH is transmitted to a pH recording and monitoring device which preferably displays the pH. The signal may be transmitted through a conductor or by a radio transmitter. Components other than pH may be monitored such a pCO2, and pO2.
