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.

Posted on by Posted in Biotronik, Bradycardia, Cardiac Pacing, Cardioversion/Defibrillation, Heart Failure (CHF), Tachycardia

Biotronik Ilesto ICD CRTD David Prutchi PhD www.implantable-device.comBiotronik announced that FDA granted approval for its Ilesto 7 implantable cardioverter-defibrillator/cardiac resynchronization therapy defibrillator (ICD/CRT-D) series. According to the press release:

“BIOTRONIK lives up to its reputation for excellence in design and manufacturing with the introduction of the Ilesto family, and the new Ilesto DX device. Physicians depend on complete and timely information, and Ilesto DX with BIOTRONIK Home Monitoring® certainly delivers. With this device, physicians can receive atrial information to ensure diagnostic accuracy and identify previously undetected atrial fibrillation. They also receive peace of mind that there is less risk of complications due to the single lead,” said Paul Woodstock, executive vice president of sales and marketing at BIOTRONIK, Inc., USA. “Ilesto’s smaller footprint will be more comfortable as well, which may present a win-win solution for patients and physicians alike.”

Sorin Receives Conditional FDA IDE Approval to Study its Paradym CRT-D IPG and SonRtip Hemodynamic Sensor Lead

Posted on by Posted in Bradycardia, Cardiac Pacing, Cardioversion/Defibrillation, Heart Failure (CHF), Sorin, Tachycardia

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.

One for History Buffs: Pacemaker Made in Brasil

Posted on by Posted in Bradycardia, Cardiac Pacing, CCC del Uruguay, CCC Medical, Museum

Implantable Pacemaker Made in Brasil. www.implantable-device.com David Prutchi Ph.D.

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.

Digikon’s History

Posted on by Posted in Bradycardia, Cardiac Pacing, Digikon, History, Museum

Digikon model LD451 Ventricular Inhibited Pulse GeneratorIn response to my post “A Challenge to History Buffs:  Who Was Digikon?“, Paolo Pagani sent me the following message:

“Digikon was in the years 1977-1985 the brand name product in Italy by Biotec Biomedical Technologies of Bologna – ITALY.

Pacemakers were a Digikon O.E.M. production for the trading company of Milan Italy KONTRON already a distributor in Italy of Medtronic.

Biotec developed the first pacemaker VVIR based on physiological changes in thoracic impedance due to respiration. (Biotec RDP-3)

Biotec-Bologna was acquired by Medtronic in August 1985.”

Thank you Paolo!

The Australian Pacemaker: Telectronics (1965-1995)

Posted on by Posted in Bradycardia, Cardiac Pacing, History, Museum, St. Jude Medical, Telectronics (1965-1995)

Telectronics model 150B VVI pacemaker photographed by David Prutchi, Ph.D. www.implantable-device.comIn 1965, Australian medical device pioneer Noel Gray established Telectronics – Australia’s first manufacturing facility for producing pacemakers that were designed in-house.  Telectronics was an innovative developer, achieving some major successes in the early cardiac pacing field, for example, Telectronics’ leads allowed narrowing the pacing pulse to its current nominal of 0.5 milliseconds; encapsulating the pacemaker in titanium instead of epoxy; using a microplasma weld to join the two halves of the pacemaker capsule; creating one of the first rate-responsive ‘demand’ pacemakers; and isolating the pacemaker’s battery in a separate compartment to deal with the problem of leaking mercury-zinc batteries.

First pacemaker to be implanted in a human patient (1958)

This is a picture of the first pacemaker to be implanted in a human patient.  It was developed by Dr. Rune Elmqvist (1906–1996), a physician by training, but working for the Swedish company Elema-Schonander as an engineer.   Dr. Elmqvist  developed the device in cooperation of Åke Senning, senior physician and cardiac surgeon at the Karolinska University Hospital in Solna, Sweden.
