  • an elongated heater unit having an elongated outer wall and an elongated inner cavity and a heating element to heat the cavity;

    a battery within the heater unit operative to power the heating element; and

    a sterile, disposable casing including an elongated inner sleeve with a closed end configured to be received within the elongated inner cavity of the heater unit, the casing further including an elongated outer sleeve configured to cover the outer wall of the heater unit, the elongated outer sleeve including an opening to receive the heater unit, and a closure to seal the opening such that the heater unit is contained entirely within the sterile, disposable casing when the closure is sealed, thereby enabling an endoscope or laparoscope to be inserted into an open end of the outer sleeve to be warmed by the heater unit while preventing the heater unit from entering a sterile field.
