Abstract: Single-use electrical leads for a nerve stimulator are disclosed. The nerve stimulator has a “test mode” that determines a current value for treatment, and a “therapy mode” that administers treatment with the chosen current value. Preferably the fuse is electrically isolated from the leads that contact the patient.

Abstract: Single-use electrical leads for a nerve stimulator are disclosed. The leads include a status flag element such as a fuse, which is deliberately blown after use of the leads has begun to indicate that the leads are not to be reused. The nerve stimulator has a “test mode” that determines a current value for treatment, and a “therapy mode” that administers treatment with the chosen current value. If the fuse in the electrical leads is blown (not conducting), then the stimulator assumes that the leads have already been used and does not enter therapy mode, and optionally may not enter test mode. If the fuse in the electrical leads is intact (conducting), or not blown, then the stimulator assumes that the leads are as yet unused, and allows the user to enter either test mode or therapy mode. The fuse is deliberately blown after a particular amount of time spent in therapy mode.

Abstract: An implantable neuromodulation system and method of treating a patient through neuromodulation of a patient's body tissue. The neuromodulation system includes a portable transmitter and an implantable receiver. The implantable receiver includes one or more electrodes disposed on the distal end of one or more elongated, flexible insulated leads. The transmitter is programmable with a treatment protocol to cause the transmitter to generate a pulsed, alternating magnetic field in accordance with the treatment protocol. When the transmitter is placed in close proximity to the receiver, the alternating magnetic field pulses generated by the transmitter cause the receiver to operably generate stimulating pulses delivered via the electrode(s) to the targeted tissue of the patient.

Abstract: An electro-nerve stimulation apparatus includes a pulse generator, a first electrically conductive, insulated lead wire, a second electrically conductive, insulated lead wire, an electrically conductive transcutaneous electrode and an electrically conductive percutaneous needle electrode. Connected to one end of the first and second lead wires is a connector for electrically coupling with the pulse generator. The transcutaneous electrode is operably connected to the other end of the first lead wire. An electrically conductive adaptor is secured to the other end of the second lead wire for electrically coupling to the terminal end of the percutaneous needle electrode. The lead wire set includes a single-use mechanism adapted to effectively discourage reuse of the electrodes. In use, the transcutaneous electrode is adhered to the patient's skin distal from the desired internal stimulation site. The percutaneous needle electrode is inserted through the skin in proximity to the desired internal stimulation site.

Abstract: A wound dressing for covering a wound to the body, providing slow release of a combination of collagenic protein and oligosaccharide, enhancing vapor transmission from the wound, and enhancing healing comprises an aqueous combination of collagen and oligosaccharide coated on a mesh surface and dehydrated to a low moisture content. The ratio of oligosaccharide to collagenic protein ranges from 1:100 to 100:1, with a content (dry basis) of collagen at about 0.1 to 30 percent and oligosaccharide in the dressing at about 0.1 to 20 percent.

Abstract: An improved biocompatible composition consisting of physiologically stable microparticles carried in a lubricative suspension, solution, other fluid or gel is presented. The composition is intended to be delivered into the body through a small-bore needle, cannula, or catheter and to a tissue site for the purpose of augmenting the tissue site and surrounding area, thereby correcting a defect, filling a void, or strengthening the support structures of the tissue. The particles are a hard, metallic substance and are carbon-coated.
