Abstract: A partial hip prosthesis for reducing friction and wear in partial hip prosthesis by combining optimized geometry of the articulation and surface treatment of the prosthetic component. In the prosthesis, one of the articulating surfaces—either that of the reamed acetabulum, or that of the femoral head prosthesis is a-spherical so that a fluid-filled gap is formed at the area of major load transfer. The fluid-filled gap is sealed by an annular area of contact, over which the concave and the convex components are congruent. A prosthetic head is fixed to the femur by either a conventional stem, a perforated shell, or a femoral neck prosthesis screwed onto the femur so that it is partially covered by bone and partially exposed on the medial-inferior aspect, where it abuts the reamed cortex of the calcar region.

Abstract: Prosthetic heart valves having elastic leaflets and an elastic support structure are described. The support structure can store a load transferred from the leaflets as potential energy and then release it in the form of kinetic energy to exhibit a precursory transition from the closed position to the open position. The support structures can exhibit a sinusoidal movement profile at a base edge during the precursory transition.

Abstract: A blood pumping device is described having at least a first pump and a first pump actuator for inducing a blood flow in a body's circulatory system. The pump has one upper chamber having an inlet channel and one lower chamber having an outlet channel. The upper and lower chambers are separated by a movable valve plane provided with a one-way valve. The pump actuator induces movement of the valve plane in an upward and downward direction between the upper and lower chambers in response to control signals from a control unit. When the valve plane moves in an upward direction, the valve opens allowing a flow of blood from the upper to the lower chamber. The lower chamber is provided with a bag-like portion forcing said flow of blood to make a turn of between 110° to 150° before leaving through the outlet channel.
