Delivery device for stimulating the sympathetic nerve chain
First Claim
1. A delivery device for stimulating a ganglion of the nervous system, the device comprising:
- a first series of flexibly connected delivery contacts, wherein a leading delivery contact of the first series of flexibly connected delivery contacts is engagably associated with a trailing delivery contact of the first series of flexibly connected delivery contacts in an operative position of the delivery device; and
a second series of flexibly connected delivery contacts flexibly connected to the first series of flexibly connected delivery contacts, wherein a leading delivery contact of the second series of flexibly connected delivery contacts is engagably associated with a trailing delivery contact of the second series of flexibly connected delivery contacts in an operative position of the delivery device, wherein the delivery device maintains a substantially ovoid configuration when in an operative position; and
a third series of flexibly connected delivery contacts located between and connected to both the first series of flexibly connected delivery contacts and the second series of flexibly connected delivery contacts, wherein a leading delivery contact of the third series of flexibly connected delivery contacts is engagably associated with a trailing delivery contact of the third series of flexibly connected delivery contacts in an operative position of the delivery device;
wherein the engagable association of the leading delivery contact and the trailing delivery contact for each of the series of flexibly connected delivery contacts is independent of the engagable association of the leading delivery contact and the trailing delivery contact of any other series of flexibly connected delivery contacts;
wherein the first series of flexibly connected delivery contacts has a first diameter, the second series of flexibly connected delivery contacts has a second diameter, and the third series of flexibly connected delivery contacts has a third diameter, the third diameter being greater than the first diameter and the third diameter being greater than the second diameter in an operative position of the device.

Abstract
The present invention provides a device and assembly for electrically and/or chemically stimulating individual ganglion and a plurality of ganglia of the nervous system, and particularly to ganglia of the sympathetic nerve chain. A device is provided that generally wraps around an individual ganglion and conforms to the shape of the ganglion without exerting excessive pressure on the ganglion to damage the ganglion. An assembly is also provided that includes an axially elongated shaft that can be positioned adjacent to the sympathetic nerve chain and that can receive a plurality of ganglion stimulators that can slidably engage with the outer surface of the shaft. As additional ganglia are desired to be stimulated, each of the plurality of ganglion stimulators can be added to the shaft to engage the outer surface of the shaft and can be positioned adjacent to the ganglia desired to be stimulated.
