Problems solved by technology

Existing spiral cuff electrode do not reliability interface to small nerves.
The stiffness also does not allow the electrode to be fully adaptive, accommodating post-operative swelling of the never, which commonly occurs.
Patent to produce the electrode is hand-labor intensive with low repeatability of key process parameters.

Embodiment Construction

I. Molded Nerve Cuff

[0032]FIG. 1 shows an implant system 10 for recording, and / or stimulation, and / or blocking of a biological tissue, i.e., a nerve N in an animal, including a human. The system includes an implantable lead 12 having a proximal and a distal end. The distal end carries a cuff electrode 16.

[0033]As FIG. 2A shows, the cuff electrode 16 includes at least one electrically conductive surface 18. In the illustrated embodiment, there are three individually controllable electrically conductive surfaces 18, although more or less may be used. The surface 18 may be solid, as shown in FIG. 2C, or the surface may be segmented into isolated conductive segments electrically coupled by a wire. Alternative embodiments having segmented conductive surfaces 18 are shown in FIGS. 2D through 2F. It is to be appreciated that additional alternative configurations are possible as well.

[0034]In this arrangement, the lead 12 (see FIG. 1) comprises a molded component 28, which encapsulates a co...

Abstract

Devices, systems, and methods for recording, and / or stimulation, and / or blocking of a nerve make use of a molded cuff electrode. An electrically conductive surface is coupled to an inside surface of the elastic body of the cuff. The elastic body of the cuff is formed from a substantially homogeneous material, and the electrically conductive surface and the body assume a coiled configuration in the natural state of the cuff. An applicator tool having a body and a slider are used to implant the cuff electrode about a nerve.

Description

RELATED APPLICATION[0001]This application is a continuation of co-pending U.S. patent application Ser. No. 11 / 196,995, filed Aug. 4, 2005, and entitled “Devices, Systems, and Methods Employing a Molded Nerve Cuff Electrode,” which claims the benefit of U.S. Provisional Patent Application Ser. No. 60 / 598,695, filed Aug. 4, 2004, and entitled “Devices, Systems, and Methods Employing a Molded Nerve Cuff Electrode.” U.S. patent application Ser. No. 11 / 196,995 is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]This invention relates to nerve cuff electrodes for neuronal recording, stimulation, and blocking in animals, including humans.BACKGROUND OF THE INVENTION[0003]In the last forty years, neuromodulation and neurostimulation implantable technologies have been used extensively for a variety of indications. As such, the components of these systems have developed a significant track record and their actions on the body are reasonably well understood. Many of ...
