Abstract: A protective device that protects against nerve compression and injury during medical procedures. The device includes an elongated body having a base, and a retention flap and a closure flap joined to the base. The device further includes a closure operable to join the closure flap to the retention flap. The closure may be provided as adhesive field, magnets, a living hinge, or matable structures, such as teeth/sockets, snaps, etc., or tape, strings, sutures or other external elements may be used for joining the flaps. The body may be pretensioned to remain open, or to urge the body to assume a closed configuration. The body may be formed of foam or other flexible/compressible material so as to readily bend and conform to the body and to act to enclose and organize/confine wires/lines used in a medical procedure, and to act as a cushion between such wires/lines and the body.
