Abstract: An implant to be fastened to a tissue, a tool a kit and a method. The implant has a first end, a second end and an elongated shank made in part from a first polymer material. The implant includes a contact surface for receiving external mechanical energy for deforming the shape of the implant such that the shape of the implant can be deformed and locked in the tissue by the effect of the external mechanical energy.

Abstract: A system by which the proportion of ferromagnetic particles in a dielectric medium is measured. A magnetic field is generated by two signals in the medium: a low frequency feed and a relatively high frequency excitation. The feed magnetizes the ferromagnetic particles in the medium to the nonlinear range of the magnetization curve. The excitation is generated so that its spectrum is relatively wide and it is dense with frequency components. The level of the excitation is so high that the magnetic flux density in the medium corresponding to the excitation fluctuates nonlinearly, when the feed is at its peak value or near this. The magnetic field of the medium is measured by a secondary winding, and from the response signal produced by the sensor is detected the part resulting from the magnetic non-linearity, which part is the output signal. In the detection the response is multiplied by the signal, which arises magnetic field and includes the same random fluctuation as the response.

Abstract: An implant to be fastened to a tissue, a tool a kit and a method. The implant has a first end, a second end and an elongated shank made at least partly of a first polymer material. The implant comprises a contact surface for receiving external mechanical energy for deforming the shape of the implant such that the shape of the implant can be deformed and locked in the tissue by the effect of said mechanical energy.
