Abstract: A liquid-filled sealing cuff of an airtight surgical ventilating device is protected from laser-effected damage during laser surgery by a liquid-containing barrier cuff positioned between an area of the laser surgery and the liquid-filled sealing cuff. The body of the surgical ventilating device is formed of a matte-finished flexible metal tube in the area of the laser surgery to resist damage by laser beam impact and to dispose highly unfocused light when a surgical laser beam is directed against the outer surface of the metal tube. A locking ferrule prevents disengagement of an atraumatic insertion tip of the device from the flexible metal tube.

Abstract: A disposable flexible medical device or probe and a reusable connector are provided. The disposable probe comprises a flexible tube of resilient plastic having a central major lumen and two or more minor lumens formed in the walls of the tube. Flexible electrically-conductive wires of undulating configuration extend through the minor lumens for conveying electrical signals from the distal end of the probe within the human body to suitable external monitoring instruments. The proximal end of the probe is formed as a female connector having longitudinally extending contacts on the inside surface of the major lumen, the contacts preferably being formed as an integral part of the wires extending through the minor lumens. A relatively rigid reusable male connector is employed as a coupling means.
