A high-frequency miniature pressure ventilator system including a variable volume pressure chamber arranged to surround a portion of the thoracic cavity of a body so as to isolate the portion of the body from atmospheric pressure. A pump assembly is operable for varying the pressure within the chamber so as to apply negative external pressure to the portion of the body during a negative cycle of operation. A valve assembly is operable for opening the chamber to a predetermined pressure during a positive cycle of operation in order to normalize a base pressure from which the pressure within said chamber is varied. In another embodiment there is provided a high-frequency pressure ventilator system including a variable volume pressure chamber arranged to surround the head of a body so as to isolate the head from atmospheric pressure. A pump assembly is operable for varying the pressure within the chamber so as to apply positive external pressure to the head during a positive cycle of operation. A valve assembly is operable for opening the chamber to predetermined pressure during a negative cycle of operation in order to normalize a base pressure from which the pressure within said chamber is varied.

A stent device for minimizing deployment related injuries. The stent device includes at least one structural block of a desired length and includes a plurality of projection struts. The projection struts each have a defined shape, and form a foldable pattern so that the stent device folds onto itself. An expansion mechanism is stored within the structural block. The expansion mechanism unfolds the foldable patterns of the projection struts using expansion so that minimal damage occurs to a vessel wall.
