摘要： An obturator assembly includes an obturator at least partially positionable within a lumen of a device. The obturator has a distal end with a tip portion and an opposing proximal end. A sensor assembly is at the tip portion. The sensor assembly is configured to sense one or more environmental characteristics and to generate one or more signals representative of the one or more environmental characteristics. A hub is operatively coupled to the obturator. The hub is also operatively coupled to electronic circuitry that is coupled in signal communication with the sensor assembly. In certain embodiments, the electronic circuitry is configured to receive the one or more signals from the sensor assembly and transmit the one or more signals to remote reception circuitry and/or display a datum representative of the one or more environmental characteristics on a display of the hub.

摘要： 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.

摘要： An obturator assembly includes an obturator positionable within a lumen of a device and movable within the lumen between a first position and a second position. The obturator includes a distal tip portion, wherein, with the obturator in the first position, the distal tip portion limits fluid communication through the lumen and, with the obturator in the second position, the distal tip portion provides fluid communication through the lumen.
