1. An apparatus for applying external pressure variation to a given body portion of a user'"'"'s body comprising:

  • a sheath means adapted to be retained with respect to the given body portion;

    said sheath means including a flexible portion which is adapted to be formed into a selected shape which closely conforms with the given body portion to provide a closely form-fitting enclosure which envelopes the given body portion at essentially a minimum spacing therefrom when said sheath means is retained with respect to the given body portion;

    said sheath means including seal means which is operable to engage the user'"'"'s body to form within said form-fitting enclosure an enclosed space intermediate said sheath means and the given body portion;

    connection means communicating with said enclosed space and adapted to be connected to a pressure medium source for applying the pressure of a pressure medium at variance from ambient atmospheric pressure within said enclosed space; and

    means operable for selectively rigidifying said flexible portion when retained with respect to the given body portion in a manner that upon said selectively rigidifying, said flexible portion is maintained in said selected shape to provide said closely form fitting enclosure at said essentially minimum spacing throughout application of pressure within said enclosed space.
