The present invention generally relates to the insertion of needles or needle-like members. Thus, a device comprises a housing having a mounting surface adapted for application to the skin of a subject, and a needle unit connected to the housing by a hinge allowing the needle unit to pivot corresponding to a pivoting axis defined by the hinge, the pivoting axis being arranged substantially in parallel with the mounting surface. The needle unit comprises a needle having a distal pointed portion adapted to penetrate the skin of the subject, the distal portion extending generally perpendicular to the mounting surface, and a proximal portion arranged substantially corresponding to the pivoting axis, whereby the needle unit is arranged to pivot between a first position in which the distal portion of the needle is retracted within the housing, and a second position in which the distal portion projects relative to the mounting surface. The needle may e.g. be in the form of a hollow needle or a needle sensor.

A stem-like bone implant includes longitudinal structural members and tension cables that provide curvature control and support, and rigidity against bending and buckling. The longitudinal structural members and tension cables may become an integral part of a composite regenerated bone having a substantially increased strength over natural bone. The flexibility of the implant is controlled by specifically varying the structural geometry of certain portions of the implant, and by adjusting the tension in the tension cables before, during and after the implantation operation to thereby adjust the stiffness of the implant. The tension cables may be adjusted to produce asymmetric or non-uniform levels of tension in the longitudinal structural members.
