The radially repulsive magnetic bearing is configured to align a first element of a first platform with a second element of a second platform when the first and second platforms are coupled together.

An implantable medical device for implantation in a hip joint is provided. The medical device comprises: at least one artificial hip joint surface adapted to replace at least the surface of at least one of the caput femur and acetabulum. At least one artificial hip joint surface comprises: a positioning hole with at least one opening in said at least one artificial hip joint surface. The hole is adapted to be placed and dimensioned such that the medical device is adapted to be fitted using a positioning shaft and at least partly surround the shaft, for positioning the at least one artificial hip joint surface in a desired position in the hip joint. The hole is adapted to be fitted using the positioning shaft, when the shaft is stabilized and placed in at least one of the femoral bone and the pelvic bone for positioning said medical device inside the hip joint.

A method and device for skin treatment include using a laser diode bar stack to generate a mix of at least two laser wavelengths for application to a skin area to be treated.

Embodiments of the invention include a compact, lightweight, hand-held laser treatment device that combines the emissions of two separate laser energy sources into a common optical pathway for improved therapeutic effect. In some embodiments, the device includes a housing having separate first and second laser sources disposed within the interior thereof. In some embodiments, the laser energy emissions from the two internal laser sources can be individually or concurrently transmitted to a delivery tip of the device via a laser transmission path also defined within the interior of the housing. In some embodiments, the structural and functional features of the first and second laser sources, in concert with the unique architecture of the laser transmission path, can be configured to provide efficacy and efficiency in the operation of the device within the spatial constraints of the lightweight, hand-held housing thereof.
