St Jude Receives CE Mark for Quadra Assura MP™ Multipoint CRT-D

Posted on by Posted in Bradycardia, Cardiac Pacing, Cardioversion/Defibrillation, Heart Failure (CHF), St. Jude Medical, Tachycardia

SJM_QuadraAssuraMPSt. Jude Medical today announced CE Mark approval of its next-generation quadripolar device, the Quadra Assura MP™ cardiac resynchronization therapy defibrillator (CRT-D). The device features MultiPoint™ Pacing (MPP) technology that enables physicians to pace multiple locations on the left side of the heart. This gives the clinician more choices to best optimize cardiac resynchronization therapy (CRT) pacing to meet individual patient needs.

According to the press release:

The Quadra Assura MP CRT-D is designed to work with the Quartet™ Lead, which has four electrodes to offer maximum flexibility for different pacing configurations. The new MPP capability allows physicians to program simultaneous or sequential delivery of two left ventricular (LV) pulses per pacing cycle, rather than the standard single pacing pulse. The capability to deliver two LV pulses per cycle allows physicians to tailor CRT pacing for each patient, potentially leading to more effective outcomes compared to single site pacing, which may be particularly beneficial in patients not responding to traditional bi-ventricular pacing therapy.

Sorin Launches Reply 200 Pacemakers with Sleep Apnea Monitoring

Posted on by Posted in Bradycardia, Cardiac Pacing, Sleep Apnea, Sorin

Sorin Reply 200 with apnea monitor David Prutchi PhD www.implantable-device.comSorin announced today CE mark approval and the European commercial launch of the REPLY ™ 200 family of pacemakers featuring Sleep Apnea Monitoring (SAM).  According to the press release:

Sleep apnea is highly prevalent and vastly undiagnosed in pacemaker patients. It increases the mortality risk and the risk of common cardiovascular co-morbidities such as hypertension, atrial fibrillation (AF) and heart failure (HF). Moreover, sleep apnea complicates the management of common cardiovascular co-morbidities.

The REPLY 200 SR and DR pacemakers automatically screen patients for the risk of severe sleep apnea using a highly reliable sensor that measures ventilation. The Respiratory Disturbance Index (RDI), calculated and reported by the pacemaker, has been validated against polysomnography, the gold standard method used to diagnose sleep apnea.

Neurotech vagus nerve stimulator for epilepsy www.implantable-device.com David Prutchi PhD

In June 2012 Neurotech s.a. (http://www.neurotech-int.eu), a Belgium based developer and manufacturer of neurostimulation devices, obtained the CE Mark for its ADNS-300 system for the treatment of refractory epilepsy. According to the press release:

“Advens therapy” uses the ADNS-300 stimulator as a therapeutic option for those patients who are refractory to anti-epileptic drugs and are not eligible for epilepsy (brain) surgery. The ADNS-300 is the world’s first rechargeable neurostimulator for vagus nerve stimulation. The device includes an innovative electrode and a promising “sensing” feature that may prove to be a significant technological breakthrough in the control of response to the therapy. Patients use a remote controller and charger to turn the system on/off and to recharge the neurostimulator.  “Rechargeable systems may prove to be more cost-effective, especially if surgical operations to replace batteries are avoided over time. This helps patients to maintain a more independent life, with a lower risk of potential complications associated with battery replacement surgery.” ‘The role of Rechargeable Systems in Neuromodulation Paul Eldridge et al.’

FDA Approves St. Jude’s Ellipse™ and SJM Assura™ Portfolio of ICDs and CRT-D Devices

Posted on by Posted in Cardiac Pacing, Cardioversion/Defibrillation, Heart Failure (CHF), St. Jude Medical, Tachycardia

St Jude Medical Assura Ellipse ICD CRT-D www.implantable-device.com David Prutchi PhD

St. Jude Medical announced FDA approval of its next-generation Ellipse™ and SJM Assura™ portfolio of implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds). The new devices are designed to lower the risk of lead abrasion and to ensure high-voltage therapy delivery.

According to the announcement:

The Ellipse and SJM Assura family of devices feature the DynamicTx™ Over-Current Detection Algorithm, which automatically adjusts shocking configurations to ensure the delivery of high-voltage therapy even if an electrical short in one portion of the system were to occur. In addition, the next-generation Ellipse and SJM Assura portfolio of implantable defibrillators have a low-friction coating on the device can, which has been demonstrated in testing to significantly reduce the friction between the device and leads. As such, the low-friction coating provides an extra layer of insulation and is designed to reduce the risk for lead-to-can abrasion, the most common type of lead insulation failure in the industry.

NeuroVista Publishes Study Results for their Implantable Seizure-Warning Device

Posted on by Posted in EEG Monitoring, Epilepsy, NeuroVista

 

NeuroVista implantable device for seizure detection www.implantable-device.com David Prutchi PhD

Seattle-based NeuroVista was founded in 2002 by Dr. Daniel DiLorenzo to develop an implantable device for the early detection of epileptic seizures.  The NeuroVista seizure advisory system is based on an implantable device that senses EEG irregularities that precede a seizure. Early warning allows patients to take medicine and find a safe place to lie down. Although some epilepsy sufferers can feel seizures coming, many cannot.

In NeuroVista’s Seizure Advisory System (SAS), intracranial EEG signals are recorded through electrodes implanted between the skull and the brain surface. Data storage and signal telemetry takes place within the pectorally-implanted can that transmits signals wirelessly to an external handheld device that processes the data and transmits visual and audible signals to the patient. The external pager-like receiver displays a blue light when there is a low likelihood of seizures, white indicates medium susceptibility, and red alerts to a high likelihood of impending seizure.

Results of the system on 11 patients were published in the Lancet an a paper entitled “Prediction of seizure likelihood with a long-term, implanted seizure advisory system in patients with drug-resistant epilepsy: a first-in-man study.”  From the paper:

Impulse Dynamics OPTIMIZER IVs IPG for treatment of heart failure

Impulse Dynamics (yes, the company for which I work) launched its new, CE-marked OPTIMIZER™ IVs implantable device for the treatment of heart failure at the 79th Annual Meeting of the German Cardiac Society (Mannheim, Germany, 3–6 April 2013).

The OPTIMIZER™ IVs Implantable Pulse Generator (IPG) is a programmable telemetric device intended to treat moderate to severe heart failure resulting from left ventricular dysfunction by monitoring intrinsic cardiac electrical activity and delivering Cardiac Contractility Modulation (CCM) signals during the ventricular absolute refractory period.  These electrical signals are intended to influence myocardial properties in patients, thereby reducing their symptoms and improving quality of life and exercise tolerance.

The OPTIMIZER™ IVs IPG was designed to deliver CCM signals during the ventricular absolute refractory period in synchrony with locally-sensed electrical activity. The microprocessor controlled implantable device comprises intracardiac electrogram sensing circuits, control logic, communications circuitry, and circuitry to generate the CCM signals.  Electrogram signals are detected from and CCM signals are delivered to the heart using standard chronically-implantable bipolar pacing leads.  The implant procedure is similar to implantation procedures for other cardiac rhythm management devices.

Medtronic’s Fully Implantable Percutaneous Nerve Stimulation (PNS) System for Treatment of Lower Back Pain

Posted on by Posted in Medtronic, Pain, PNS, Spinal Cord Stimulation

Medtronic Activa PC used by Functional Neurostimulation for treating Alzheimer'sIn May 2011 Medtronic received the CE Mark for the first 16-electrode, fully implantable system for the percutaneous delivery of peripheral nerve stimulation (PNS) in the management of chronic back pain.

PNS involves an implant of electrical leads just under the skin of the lower back.  These leads are connected to a stimulator which delivers mild electrical impulses to the nerves, interrupting pain signals traveling through the nervous system to the brain.

Medtronic today announced the first patient enrollments in the SubQStim II pivotal clinical trial to pursue FDA approval PNS (also known as subcutaneous nerve stimulation or SQS), for the reduction of chronic, intractable post-surgical back pain.
