Abstract
A smart obturator assembly includes a hub forming a central passage. The hub is configured to couple to a proximal end of a device that forms a lumen such that the central passage is in fluid communication with the lumen. A collar on the hub includes electronic circuitry in signal communication with remote reception circuitry. An obturator is movably positionable within the lumen. The obturator is movable within the lumen between a first position and a second position. The obturator includes a distal end and a sensor at the distal end. The sensor is configured to sense an environmental characteristic within a patient's blood stream, generate a signal representative of the environmental characteristic, and transmit the signal to the electronic circuitry. The electronic circuitry is configured to receive the signal and transmit the signal to the remote reception circuitry.
