摘要: The heart pump according to the invention includes a casing internally defining a substantially spherical cavity (10) housing: - a rotating shutter (12) secured to the cavity (10) so as to be rotatable about an own rotation axis; - an oscillating shutter (14), secured to the rotating shutter (12) so as to be rotatable relative to the latter about a rotation axis transversal to the rotation axis of the rotating shutter relative to the casing; - a guide ring (18'), secured to the oscillating shutter (14) so as to allow the latter to rotate relative to the same ring (18). The guide ring is arranged to move within a seat formed in the substantially spherical cavity (10) while lying in a substantially slanting plane relative to the rotation axis of the rotating shutter (12) and thereby making the rotating shutter (12) rotate. This allows constructing an artificial heart of very small size that can be driven either by a motor member or by an induced muscle contraction.

摘要: The engine according to the invention comprises: a) a casing (12) inside which an annular cavity is formed; b) an annular rotor (14), housed within the annular cavity; c) multiple mobile chamber elements (10), secured to the rotor (14). The annular cavity has, in some regions, cross-sectional sizes substantially greater than the cross-sectional sizes of the rotor (14) so as to define multiple hollow chambers (16, 18). The mobile chamber elements (10) can be displaced, within at least part of the hollow chambers, transversally relative to the annular body of the rotor (14) while contacting the walls of the same annular cavity and separating in fluid-tight manner the hollow chamber portion in front of the mobile chamber element (10) from the hollow chamber portion behind the mobile chamber element (10).
