Abstract: The present invention relates to a surgical spacer device (100) for a joint, comprising a substantially cylindrical or truncated-cone-shaped main body (101), internally hollow and configured for insertion in a distracted joint (1, 2); the main body (101) comprising: a first terminal surface (102) substantially flat and configured to abut onto a first bone portion (1) of the joint (1, 2); a second terminal surface (103) substantially annular and configured to abut onto a second bone surface (2) of the joint (1, 2) opposite the first bone portion (1), the second terminal surface (103) having a first opening (10) for access to the second bone portion (2); at least one lateral element (104) configured for maintaining a three-dimensional spaced structure between the first terminal surface (102) and the second terminal surface (103), the at least one lateral element (104) defining a second opening (20) configured for allowing a lateral access inside the main body (101) and further an access to the second bone porti

Abstract: The invention relates to a method for surgical application of a glenoid anchor of a shoulder joint prosthesis and instruments advantageously used in the method. The method includes making a delto-pectoral incision providing a delto-pectoral access to a shoulder joint; with the delto-pectoral access being suitable for inserting at least one machining tool; and making a trans-deltoid incision providing a trans-deltoid access to the humeral head; with the trans-deltoid access being suitable for inserting a stem of a machining instrument to be mounted on the machining tool for machining the glenoid cavity.

Abstract: A method of quantifying the amount of glucose in a sample is provided herein that may further comprise an interferent such as mannitol. At least two measurements are obtained using measurement methods that differ in their sensitivity to the amount of interferent in the sample, thus enabling the results to be compared to determine whether any interferent is present in the sample. A glucose sensor for carrying out a method described herein is also provided.

Abstract: A water propulsion unit having an intake housing, a pump housing and an outlet with two spaced apart counter rotating impellers being located in the pump housing. The impeller blades on one impeller have an opposite pitch to the blades of the second impeller. The impellers are configured so that one of the impellers will impart less energy to the water as it passes the blades of the impeller than the second impeller.

Abstract: An electric power generation system has a multiple jet ejector assembly for recirculating an exhaust stream. The system includes a fuel cell stack having a reactant stream inlet, a reactant stream outlet and at least one fuel cell. A pressurized reactant supply provides a reactant to the multiple jet ejector assembly. The multiple jet ejector assembly includes two motive flow inlets, one suction inlet, fluidly connected to the reactant stream outlet to receive a recirculated flow from the fuel cell stack, and one discharge outlet, fluidly connected to the reactant stream inlet to provide an inlet stream to the fuel cell stack. A pressure regulator is interposed between the pressurized reactant supply and the two motive flow inlets of the multiple jet ejector assembly. A first solenoid valve is interposed between the first motive flow inlet and the regulator. A second solenoid valve is interposed between the second motive flow inlet and the regulator.
