Abstract
Cervical dam for capturing liquid draining from uterus during gynecological procedures while simultaneously providing an aperture through the cervical dam for insertion and manipulation of a medical device. The aperture may be a preformed slit elastomeric aperture, a duck billed valve, a multi-disc elastomeric valve, or a universal seal. The cervical dam includes a drainage port through the body of the cervical dam, a drainage tube attached to the drainage port, and a handle, which may be detachable, affixed to the cervical dam for placement, manipulation and removal of the cervical dam. Also disclosed are methods for performing a gynecological procedure by placing a cervical dam over the cervical canal inserting a medical instrument through the cervical dam into the cervical canal, performing a procedure, and withdrawing the medical instrument, and by determining the amount of fluid input to a patient during the procedure and the amount drained from the patient during and after the procedure, and comparing the two.
