Northstar was founded in 1999 as Vertis Neuroscience headquartered in Seattle, WA, and the original goal was to develop electrical stimulation for chronic back pain. In 2003, under its new name, Northstar Neuroscience, then developed the Renova cortical stimulation system to deliver targeted electrical stimulation to the brain cortex as a treatment for stroke-related upper extremity.

Intrapace was founded in Mountain View, CA by Mir Imran in 2001 to develop an implantable system for the treatment of obesity. Once implanted and activated, the Abiliti system is designed to detect when a person consumes food or drink. When food or drink is detected, the system delivers a series of low-energy electrical impulses to the stomach intended to create a feeling of fullness.
In January 2011 Intrapace received the CE Mark for the Ability system.
The Ability IPG connects to the stomach via a lead that integrates the food sensor and stimulation electrodes. The sensor is able to detect food and drink and can trigger the abiliti stimulator device to create a feeling of fullness. These eating events, along with physical activity the patient engages in, are automatically recorded and available for downloading to a personal computer using the connect.abiliti Wand.

Transneuronix, Inc. was founded in 1995 and was based in Mount Arlington, New Jersey. It was acquired by Medtronic in 2005.
Before its acqusition by Medtronic, Transneuronix developed the Transcend, an implantable gastric stimulator device for the treatment of obesity by electrical stimulation of the stomach. Later, Medtronic developed the Transcend II IPG. Continue reading
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
Transoma was the name that Data Sciences International of St Paul, MN adopted in 2003 when it re-fucused its animal telemetry implant business to develop an implantable wireless system to capture electrocardiogram data for diagnosing human cardiac arrhythmias, as well as to monitor the electrical activity of the heart and transmit data from the patient’s home to monitoring centers.
In 2007, Transoma received FDA’s approval for its Sleuth implantable device to wirelessly monitor a patient’s ECG for possible diagnosis of arrhythmias and prevention of syncopal episodes. The Sleuth ECG Monitoring System included a High Definition Implantable Loop Recorder (HD-ILR), a Personal Diagnostic Manager, a Base Station and a Monitoring Center staffed 24/7. 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.
From Patent Application Publication: US 2011/0137370 A1
Enopace Biomedical Ltd. was founded in 2008 by Yossi Gross in Caesarea, Israel.
Very scant details are available besides that it is developing a neuromodulation system to treat patients with congestive heart failure. According to the company, its technology consists of a minimally invasive, implantable neurostimulation device that increases cardiac efficiency by reducing left ventricular workload.
From Enopace’s patent applications, it seems that Enopace’s device consists of a stimulation unit that is placed within the aorta close to the heart, and which is driven wirelessly from a coil that is placed within a vein closeby to the artery. The transmitting coil is in turn driven from an implanted control unit that is implanted subcutaneously. Continue reading

CVRx was founded in Minneapolis, MN in 2001 by Dr. Robert Kieval to develop an implantable system for the treatment of hypertension.
CVRx’s implantable pulse generators deliver stimulation to the baroeceptors in the carotid arteries to induce a baroreflex that causes a drop in blood pressure in patients with refractory hypertension. Continue reading
Second Sight Medical Products, Inc., located in Los Angeles, CA, was founded in 1998 by Alfred Mann to develop a retinal prosthesis to provide sight to patients blinded from outer retinal degenerations, such as Retinitis Pigmentosa.
Second Sight’s Argus II Retinal Prosthesis System is intended to provide electrical stimulation of the retina to induce visual perception in blind individuals. The implant is an epiretinal prosthesis surgically implanted in and on the eye that includes an antenna, an electronics case, and an electrode array. The external equipment includes glasses, a video processing unit (VPU) and a cable.

St. Louis, MO startup EndoStim is developing an implantable stimulator to treat gastro-esophageal reflux disease (GERD) by delivering stimulation to the lower esophageal sphincter. The IPG is connected to an EndoStim implantable bipolar lead with electrodes that are stitched and secured into the lower esophageal sphincter muscle during laparoscopy. Continue reading
Sicel Technologies, Inc. was founded in 1999 and was based in Morrisville, NC. It ceased operations in 2010 after it declared bankruptcy.
Sicel developed an implantable dosimeter that was 2 mm in diameter and 18 mm long, and was injected into the tumor to send back readings to an external receiver via RFID. Continue reading
Alfred E. Mann holds B.A. and M.S. degrees in physics from the University of California, Los Angeles and honorary doctorate degrees from the University of Southern California, The Johns Hopkins University, Western University and the Technion Institute (Israel), as well as, Research Professor, University of Southern California, and Adjunct Professor, Dept. of Bioengineering, University of California Los Angeles.
Alfred Mann has founded 17 companies in his career. The AIMD companies currently within his control are:
Dr. Fischell received his BSME degree from Duke University and MS and Sc.D. degrees from the University of Maryland. Dr. Fischell was employed at the Johns Hopkins University where he was the Chief Engineer of the Space Department and worked on more than 50 spacecraft. His interests at Johns Hopkins then turned to the invention of new medical devices such as pacemakers and implantable heart defibrillators. Starting in 1969, Dr. Fischell began the formation of 14 private companies that licensed his patents on medical devices. These companies include Pacesetter Systems, Inc. (now called St. Jude Medical), IsoStent, Inc., NeuroPace, Inc., Neuralieve, Inc., Angel Medical Systems, Inc, and Svelte Medical Systems, Inc. Dr. Fischell is a prolific inventor with over 200 issued U.S. and foreign patents, many of which have been the basis for new medical device companies. Continue reading

NeuroPace is a privately-held company in Mountain View, CA. Their RNS® implantable stimulator, along with depth leads and cortical strip leads are designed for the treatment of medically refractory partial epilepsy.
Unlike Cyberonics’ VNS IPGs, the RNS neurostimulator is designed to detect abnormal electrical activity in the brain and respond by delivering electrical stimulation to normalize brain activity before the patient experiences seizure symptoms. The neurostimulator is implanted in the cranium and connected to one or two leads that are implanted near the patient’s seizure focus. Continue reading
