Abstract: An earpiece for cleaning wax or other foreign material from the ear canal of a patient or delivering a therapeutic agent into the ear canal. The device has a fluid outlet that directs the fluid passing therethrough at an oblique angle to the longitudinal axis of the device. The fluid is thereby directed at the wall of the ear canal so reducing the likelihood of damage to the delicate structures of the eardrum. The device is also designed to allow inspection of the ear canal when it is in place so removing the need of repositioning equipment following cleaning of the canal.

Abstract: A knee prosthesis of the meniscal knee type having at least a tibial component, a femoral component and a meniscal bearing to be placed between the tibial and femoral components. The bearing surface of the femoral component having a first anterior portion having a radius of curvature greater than the radius of curvature of a second posterior portion and the meniscal bearing having an upper surface having first and second bearing portions respectively substantially congruent with the first and second bearing portions of the femoral component. The first and second bearing surface of the meniscal bearing being separated by a short area which is planar or has a longer radius of curvature than either of the first and second bearing surface. The meniscal bearing has a heel extending posteriorly beyond the extend of the concave portion of its upper surface.
