Abstract: A device for delivering an IV catheter to an IV infusion site is disclosed. The device includes a cylindrical housing adapted to fit into the hand of the clinician. A catheter assembly is disposed in the housing and can be advanced to an extended position and retracted. The catheter assembly includes a needle adapted to be inserted into the vein and the catheter is mounted on the needle to allow the catheter to be removed at will. The catheter assembly is rotated as the needle is inserted into the vein. Preferably the catheter assembly is rotated during the insertion of the needle and catheter. After the needle and catheter are inserted into the vein, the needle is retracted into the housing leaving the catheter in place. The housing and the needle can now be discarded.

Abstract: A railway rail fastening assembly, for suspending a railway rail (100) at discrete locations along its length above a rail foundation, comprises a pair of elastic members (5) for support the head of the rail (100), a pair of brackets (6) for applying a lateral clamping force to respective ones of the elastic members (5), a baseplate (1) having first and second shoulders (3,4), and a pair of wedge members (7), each wedge member (7) being inserted between an associated one of the shoulders (3,4) and an adjacent bracket (6) thereby to maintain the said lateral clamping force, wherein at least one (4) of the said first and second shoulders (3,4) is removable from the said baseplate (1) and is held in position on the baseplate (1) by the said lateral clamping force.

Abstract: An improved cochlear implant and method of stimulating are disclosed. The method comprises stimulating an electrode array using a set of current stimuli having different geometries, so as to provide a more regular and monotonic set of pitch percepts for a user. In one embodiment, this may be achieved by combining different modes of stimulation for a patient, so that some channels utilise one mode and other channels utilise one or more different modes.
