Nevro Corporation (formerly NBI Development) was founded in 2006 by Dr. Konstantinos Alataris.  The Menlo Park, CA company developed a pain management concept that originated at the Mayo Clinic into a spinal cord stimulation system for back and leg pain.

According to Nevro, their unique stimulation waveform achieves pain relief without paresthesia or uncomfortable stimulation.  Few details are available about the waveform, but Nevro’s Spanish distributor’s brochure specifies it as high-frequency stimulation at 10,000 Hz.  This is consistent with Nevro’s patent applications which teach that “high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient’s spinal cord region to address low back pain without creating unwanted sensory and/or motor side affects.” Continue reading→

CCC del Uruguay Teros SSI pacemaker model 503CCC is one of the oldest pacemaker manufacturers in the world. It was founded in 1969 by Dr. Orestes Fiandra, who performed the first succesful, human, long-term pacemaker implant in the world.

This was achieved in Uruguay on February 2, 1960 by Dr. Orestes Fiandra and Dr. Roberto Rubio. The pacemaker was manufactured by Dr. Rune Elmqvist of Elema-Schönander in Sweden, and was implanted in Uruguay in a 34-year-old patient with AV block. This unit worked successfully for nine and a half months, until the patient died of sepsis from an unrelated infection. Continue reading→

EnteroMedics’ Maestro RC Vagus Nerve Stimulator for Obesity Management

Posted on by Posted in EnteroMedics, Gastric Stimulation, Obesity, Vagus Nerve Stimulation

EnteroMedics Inc. was founded in St. Paul, MN in 2002 to develop a platform for vagus-nerve stimulation, primarily for obesity management.  In March 2011 EnteroMedics received the CE Mark for its second-generation system – the Maestro RC.

The EnteroMedics Maestro RC device delivers VBLOC® vagal blocking therapy to through laparoscopically implanted leads to intermittently block the vagus nerves using high-frequency, low-energy electrical impulses. VBLOC Therapy is intended to target the multiple digestive functions under control of the vagus nerves and to affect the perception of hunger and fullness. Continue reading→

In June 2011, Israeli neuromodulation systems developer BioControl Medical spun-off CerebralRx to market its FitNeS vagus nerve stimulation system for the treatment of refractory epilepsy.

The FitNes system employs platform technology developed for the CardioFit® system for treating congestive heart failure (HF). CerebralRx spun out of BioControl Medical to expand the use of this technology outside of cardiology for the treatment of a range of neurological disorders, including epilepsy.

Cyberonics was founded in Houston, TX in 1987 to develop an implantable device for the treatment of epilepsy.  In July 1997, The FDA approved the VNS Therapy System (formerly known as the NCP® NeuroCybernetic Prosthesis System) as an adjunctive epilepsy treatment for adults and children over 12 years of age with partial onset seizures refractory to drugs.

Cyberonics currently markets the VNS Pulse and VNS Demipulse IPGs, which offer approximately 6 years of longevity at nominal stimulation settings (2 mA, 20 Hz, 500 msec, 10% duty cycle into a 4 kOhm load).
