Implantable device for the stimulation of bone growth
First Claim
1. An implantable device, for the stimulation of bone growth, havinga pickup coil arrangement (120) includinga pickup coil (10, 110) and at least a first and a second connection (16, 18, 110a, 110b) therefor, and an elongated cover (14, 114) having a peripheral surface and a pair of opposing end surfaces, of a tissue-compatible material, surrounding the pickup coil (10, 110);
- andfirst and second electrical conduction means (22, 122;
24,
124) establishing first and second tissue connections;
wherein said first conduction means comprisesa tissue electrode, including an extended, strip-like, planar tissue electrode element (44,
144), coupled to and extending longitudinally along the cover (14,
114), and projecting edgewise substantially perpendicular to said peripheral surface thereof, said tissue electrode being coupled to one (18, 110b) of the connections (16, 18;
110a, 110b) of the pickup coil;
said second conduction means comprises at least one connector device (124) coupled to the other (16;
110a) of the connections (16, 18;
110a, 110b) of the pickup coil; and
a flexible insulated wire (122) is provided, interconnecting each connector device (124) and said other connection (16;
110a) of the pickup coil.

Abstract
An implantable device for the stimulation of bone growth, the device having an elongated pickup coil arrangement that is provided with connectors for tissue electrodes. An extended and strip-like tissue electrode extends from the pickup coil arrangement and the connectors have a hole for a bone screw and a sleeve-like extension adapted to accommodate a Kirschner wire electrode.
