Boston Scientific has received CE Mark approval for increased longevity projections for the INCEPTA™, ENERGEN™, PUNCTUA™, COGNIS® and TELIGEN® implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds). The longevity projections are based on data submitted to the European authorities and vary for each device dependent on the model type and settings.
Projected device longevity exceeds 10 years for some models, approaches eight years for its CRT-D devices, and according to the press release is up to double that of comparable competitive device models. The company supports these devices with warranties of up to 10 years:
Warranties: INCEPTA and ENERGEN VR ICD: 10 years; INCEPTA and ENERGEN DR ICD: eight years; PUNCTUA and TELIGEN ICD: seven years; INCEPTA and ENERGEN CRT-D: six years; and PUNCTUA & COGNIS CRT-D: five years.
I received today a link to a very interesting article which plays on the fears of the public, and which I am sure will result in tough new regulations to our industry.
The article discusses how IOActive researcher Barnaby Jack reverse-engineered a “pacemaker transmitter” (probably a programmer or a MICS module) to command ICDs within a 30 feet range to fire, or to rewrite their firmware.
This is the reason why MICS (“RF telemetry”) is under renewed scrutiny by regulators. Thoughts for mitigating this issue include requiring authentication and exchange of encryption keys via close-range (inductive) telemetry and other means before allowing any programming via MICS.

Biotronik announced the European market release of BioMonitor®, an implantable cardiac device designed for the highly accurate and reliable monitoring and management of patients with atrial fibrillation (AF) or unexplained syncope.
According to Biotronik’s press release:
“BioMonitor® is a subcutaneous implantable leadless cardiac monitor for the long-term continuous remote monitoring of patients with arrhythmias such as AF, bradycardia, sudden rate drop, asystole and tachycardia.
As sensitivity and specificity are essential in the detection of arrhythmias such as AF, BIOTRONIK has developed ClearSense Technology with a unique three-vector signal detection that produces highly precise and reliable arrhythmia monitoring.

Boston Scientific has received regulatory approval to market the RELIANCE® 4-FRONT™ lead, its next generation implantable defibrillation lead now available in Europe and Asia. According to the press release, “The RELIANCE 4-FRONT lead is built upon the demonstrated performance and reliability of the RELIANCE lead platform with design enhancements intended to simplify the implant procedure. With more than 350,000 implants worldwide, RELIANCE leads have demonstrated a 98.9 percent survival probability at 8 years.
“Leveraging the RELIANCE platform, we made a series of targeted design enhancements with RELIANCE 4-FRONT to improve and simplify implantation,” said Kenneth Stein, M.D., chief medical officer of Boston Scientific’s Cardiac Rhythm Management Group. “RELIANCE 4-FRONT represents our continued dedication to product innovation to meet the needs of patients and physicians.”

Boston Scientific Corporation received CE Mark approval for use of its Vercise™ Deep Brain Stimulation (DBS) System for the treatment of Parkinson’s disease. The Vercise DBS System is the first and only commercially available DBS system to incorporate multiple independent current control, which is designed to selectively stimulate targeted areas in the brain. This system is an innovative technology that is designed to provide physicians fine control of stimulation.
Bionic Vision Australia researchers announced on August 30, 2012 that they successfully performed the first implantation of an early prototype bionic eye with 24 electrodes.
According to the press release:
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 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.”

On Sept. 28, 2012 Boston Scientific announced that the FDA granted regulatory approval for its S-ICD® System, the world’s first and only commercially available subcutaneous implantable defibrillator (S-ICD) for the treatment of patients at risk for sudden cardiac arrest (SCA). The S-ICD System sits entirely just below the skin without the need for leads to be placed into the heart.
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.
Swiss medical device manufacturer Sequana Medical developed the ALFApump® System to pump fluids accummulated in the abdomen of a patient into the bladder.

St. Jude Medical today announced FDA approval of its Assura™ portfolio of implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds).The new implantable defibrillators feature SecureSense™ RV Lead Noise Discrimination, an algorithm that expands the St. Jude Medical ShockGuard® Technology and offers advanced sensing options designed to reduce the incidence of inappropriate shocks for patients with these devices.
According to St. Jude’s announcement:
Today EnteroMedics recorded revenue for the first time since it was incorporated nearly eight years ago. The company reported revenue of about $123,000 in the first quarter of the year from the sale of its Maestro RC implantable vagus nerve stimulation system for treating obesity. Revenue was generated through sales by its distribution partner in Australia.
This is an important step for an implantable device company that faced very tough times in 2009 after its US clinical trial failed to meet a critical effectiveness goal. EnteroMedics is currently conducting a pivotal trial that is expected to end in Q4 2012. EnteroMedics expects to file a premarket approval application with the FDA in the first half of 2013 if the data from the trial is positive.
