Abstract
A biological monitoring probe carrier incorporating a spiral retaining coil is easily put in place by a drive wrench passing through a guide channel with a longitudinal slot. Said channel holds the probe carrier near its distal end and holds a monitor cable alongside a shaft of the drive wrench which includes means for engaging the probe carrier to turn and advance it for the purpose of securing to tissue the retaining coil embedded in the distal end of the carrier. The proximal end of the wrench shaft includes a manipulating means for advancing the wrench a predetermined distance once the guide channel is placed against the tissue. The drive wrench is then withdrawn and the cable may then be released as the guide channel is withdrawn by allowing the cable to slip freely through the slot without need for disconnecting the monitor apparatus from the proximal end of the monitor cable.
