Implantable subcutaneous device of biocompatible material that can receive data and energy by electromagnetic coupling with at least one external device is disclosed. The implantable device bears an airtight housing and a magnet that can hold the other external device centered with the implantable device. The housing bears a hollow crown containing at least electronic device(s) and a coil, and a bottom sealing the opening of the crown in an airtight manner. The magnet has dimensions compatible with a central housing formed by the so-called internal wall of the crown and in which it is positioned.

A method for extending skin tissue involving an apparatus that it surgically implanted within the human body, and in particular, beneath the scalp area to extend hair producing tissue for reducing baldness. The apparatus is implantable through a temporary opening, and extends the living tissue over a period of time, wherein the apparatus is later removed.

The technical field of the invention is that of making surgical materials implantable in the human body. The extender device (2) comprises at least two independent resilient members (8) each having at least one end fixed to at least one of two fastening members (7), enabling the device (2) to be fixed in a living tissue along the edges (13) of an area of the tissue that is to be treated. The edges are opposite each other in the direction in which they are moved towards each other at least by the resilient members and the device further includes a common support (9) to which the opposite ends of said resilient ends (8) are connected. The members (8) deform and move relative to the common support (9) so as to entrain the fastening members (7) over the support, urging them towards each other.

An intra-cochlea electrode carrier for implantation into a helically shaped tympanic canal has a plurality of segments. Each segment has opposite first and second surfaces, the first surface defining a length between opposite ends of the segment and a width between opposite sides of the segment, a height in cross section to the width being defined between the opposite first and second surfaces of the segment. Respective electrodes are on the first surfaces of the segments. Hinges on the opposite ends of the segments connect one end of each segment to one end of another segment, whereby to connect the segments into an elongated electrode carrier, the hinges having sufficient heights relative to the widths of the first surfaces of the segments and providing sufficient spacing between the ends of the connected segments for the electrode carrier to follow a helix of a helically shaped tympanic canal when implanted therein with the electrodes on the first surfaces of the connected segments oriented toward a nerve-receptor surface of the tympanic canal. A connector connects the electrodes of the connected segments.
