Abstract
An implantable pulse generator is provided comprising a non-metallic shell adjacent a header. The header abuts an optical window in the shell. The header aligns a series of surgical or percutaneous leads with the optical window. The leads incorporate optical fibers, electrodes and contacts which distribute stimulation signals. Behind the optical window, a set of optical devices is provided which transmit or receive light from the fibers. Signal processors are provided to interpret the signals from the optical fibers, and to mitigate a continuous inductive charging function.
Claims19
A surgical lead comprising:
- a flexible panel;
- a set of electrode arrays imbedded in the flexible panel;
- a set of leads, having a set of lead bodies integrally formed with the flexible panel;
- a set of lumens;
- at least one lumen of the set of lumens, resident in at least one lead of the set of leads;
- a set of conductors in the at least one lead of the set of leads;
- a set of contacts, attached to the at least one lead of the set of leads;
- at least one conductor of the set of conductors, connected between a contact of the set of contacts and an electrode array of the set of electrode arrays;
- a set of window portals, in the flexible panel, adjacent to and distal from all electrodes of the set of electrode arrays;
- a set of optical fibers;
- a set of side firing sections;
- at least one optical fiber of the set of optical fibers, having at least one side firing section of the set of side firing sections;
- the at least one optical fiber of the set of optical fibers, resident in the at least one lumen of the set of lumens;
- the at least one side firing section positioned adjacent a window portal of the set of window portals and distal from all electrodes of the set of electrode arrays;
- a set of ferrules;
- at least one ferrule, of the set of ferrules, directly adjacent a polished end of the at least one optical fiber of the set of optical fibers, and abutting a terminal end of a flexible lead body of the set of lead bodies, the at least one ferrule having a frustoconical chamfer, surrounding and touching the at least one optical fiber of the set of optical fibers and receiving a longitudinal elastic compression force from the terminal end;
- and
- a planar lattice shield, forming a heat sink and dispersing heat in a dorsal direction, adjacent the set of leads.
