Scientists at Wake Forest University School of Medicine in Winston-Salem, North Carolina reported using a neural implant to stimulate higher-level thinking in monkeys, providing the first demonstration in primates of the sort of brain prosthesis that could eventually help people with damage from dementia, strokes or other brain injuries.  The study was published on Sept. 14 in IOP Publishing’s Journal of Neural Engineering.

One for History Buffs: Pacemaker Made in Brasil

My friend Daniel Villamil from CCC Medical in Uruguay sent me these pictures of a very unique device in his colection.  It is a late-1960s/early 1970s pacemaker made in Sao Paulo, Brasil.

UPDATE Oct 3, 2012:

CCC’s CEO Julio Arzuaga recalled that this pacemaker was manufactured in the early 1960s by the Instituto de Cardiologia Dante Pazzanese in Sao Paulo, Brasil.  The physicians leading the pacemaker team were Dr. Decio Kormann and Dr. Adib Jatene.

Dr. Orestes Fiandra used to implant these Brasilian pacemakers in Uruguay.  However, they were not very reliable.  For this reason, and with help from Drs. Kormann and Jatene, Dr. Fiandra started CCC del Uruguay as a more industrial environment for the production of pacemakers.

St. Jude Medical Receives CE Mark Approval of Eon Mini to Treat Chronic Migraine

Posted on by Posted in Migraine, Neural Stimulation, Occipital Nerve Stimulation, St. Jude Medical

St Jude Medical Eon and Eon Mini Spinal Cord StimulatorsSt. Jude Medical announced it has received European CE Mark approval of its Eon™ family of neurostimulators for treating patients with intractable chronic migraine.

According to the press release:

“Intractable chronic migraine is one of the most difficult-to-treat headache disorders,” said Professor Gennaro Bussone, M.D., head of the Neurological Department at Istituto Besta in Milan Italy. “By definition, people living with this condition are spending half their month living with debilitating headaches. This therapy expands our options in helping manage patients who suffer with disabling chronic migraine symptoms.”

Human Implants of Vestibular Prostheses at the Maastricht University Medical Center

Vestibular Prosthesis implanted at the Maastricht University Medical Center www.implantable-device.com David Prutchi Ph.D.

Physicians at the Maastricht University Medical Center implanted two patients with vestibular prostheses.  These implants are similar to a cochlear implant, but instead of sound, conveys orientation and acceleration information to the vestibular organ that assists in preserving balance.

According to lead implanter Prof. Robert Stokroos, preliminary assessment is promising, and research will be conducted to determine if the brain can integrate the information from these implants to restore balance to the patients.

There have been a number of prior human implants of different vestibular devices.   For example, in 2010 Jean-Philippe Guyot implanted a vestibular nerve stimulation device in a human subject. Their work was published in March 2011. The device was a modified Med-El cochlear implant using an electrode that was implanted near the left posterior ampullary nerve. In addition, Washington University implanted a device based on a similar approach (a modified Nucleus device by Cochlear Ltd.) on Oct. 21, 2010.  It must be noted however that these prior devices do not sense head motion, but were designed to override abnormal vestibular signals.  On the other hand, from the sketchy details that have appeared, it seems that the devices implanted in Maastricht are the first true vestibular prostheses capable of responding to orientation and acceleration.
