Sorin Kora 100 MRI pacemaker David Prutchi PhD www.implantable-device.com

Sorin announced the CE Mark approval and first implant of its KORA 100 pacing system.

According to the press release:

KORA 100 SR and DR pacemakers when implanted with the Sorin BEFLEX pacing lead enable implanted patients to undergo magnetic resonance imaging (MRI) safely.[1] Pacemaker patients are typically older than 65 years. This patient population is prone to other medical conditions such as arthritis, cancer or stroke that may require MRI examinations for optimal diagnosis and management.

The KORA 100 pacing system has been designed with both patients and physicians in mind. Device settings which allow safe operation during an MRI examination are automatically enabled when KORA 100 pacemakers detect the scanner’s magnetic field. Similarly the devices sense when a patient leaves the MRI field, and return to normal operation within five minutes. The Automatic MRI Mode feature, which is patented and available exclusively on Sorin Group pacemakers, limits the amount of time that KORA 100 pacemakers operate in MRI mode.

Implantable devices for the treatment of heart failure, David Prutchi, PhD

 

A position paper was published yesterday by the European Heart Rhythm Association reporting on the performance of new devices for the treatment of heart failure (HF). The report has been endorsed by the Heart Failure Association.

The abstract for the paper titled “New devices in heart failure: an European Heart Rhythm Association report” reads:

 Several new devices for the treatment of heart failure (HF) patients have been introduced and are increasingly used in clinical practice or are under clinical evaluation in either observational and/or randomized clinical trials. These devices include cardiac contractility modulation, spinal cord stimulation, carotid sinus nerve stimulation, cervical vagal stimulation, intracardiac atrioventricular nodal vagal stimulation, and implantable hemodynamic monitoring devices. This task force believes that an overview on these technologies is important. Special focus is given to patients with HF New York Heart Association Classes III and IV and narrow QRS complex, who represent the largest group in HF compared with patients with wide QRS complex. An overview on potential device options in addition to optimal medical therapy will be helpful for all physicians treating HF patients.

The report places special focus to patients with HF New York Heart Association (NYHA) Classes III and IV and narrow QRS complex, who represent the largest group in HF compared with patients with wide QRS complex (who are candidates for treatment with cardiac resynchronization therapy – CRT).

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.

Sorin Paradym CRT-D David Prutchi PhD www.implantable-device.comSorin announced it received U.S. Food and Drug Administration (FDA) conditional approval for its Investigational Device Exemption (IDE) application and clinical trial protocol for RESPOND CRT. The trial will study the safety and effectiveness of the innovative SonR cardiac resynchronization therapy (CRT) optimization system in patients with advanced heart failure. RESPOND CRT is a multi-center, randomized, two-arm, double-blinded, prospective trial that will enroll more than 1,000 patients in the United States and other geographies.

The SonR optimization system is comprised of the SonR hemodynamic sensor embedded in the SonRtip atrial pacing lead and the PARADYM RF SonR CRT-D device, which includes a unique algorithm to automatically optimize the patient’s atrioventricular (AV) delay and interventricular (VV) delay timing. While there are several CRT systems on the market, studies have shown that approximately one-third of patients with advanced heart failure do not effectively respond to CRT. The SonR system is the first and only CRT hemodynamic sensor based system designed to automatically adjust on a weekly basis. The timing of electrical impulses delivered to the heart is based on the patient’s heart activity and need – with the goal of improving the patient’s response to CRT. Typically this device re-programming is done manually in the clinic using echocardiography.
