Enopace's implantable device

From Patent Application Publication: US 2011/0137370 A1

Sorin recently announced a $5 million investment in Israeli startup Enopace Biomedical, which is developing an endovascular neurostimulation system for heart failure.  Back in October 2011 Sorin invested $7 million to finance the initial clinical studies of Enopace’s technology as well as ongoing product development.

Very scant details are available besides that it is developing a neuromodulation system to treat patients with congestive heart failure. According to the company, its technology consists of a minimally invasive, implantable neurostimulation device that increases cardiac efficiency by reducing left ventricular workload.

From Enopace’s patent applications, it seems that Enopace’s device consists of a stimulation unit that is placed within the aorta close to the heart, and which is driven wirelessly from a coil that is placed within a vein closeby to the artery. The transmitting coil is in turn driven from an implanted control unit that is implanted subcutaneously.

Israeli business news website “Globes” interviewed Enopace’s CEO Amir Dagan, and reported in February 2013:

EnteroMedics Submits PMA of the Maestro VBLOC System for Treatment of Obesity

Posted on by Posted in Diabetes, EnteroMedics, Gastric Stimulation, Obesity

EnteroMedics  reported that it has submitted its pre-market approval application for FDA review of its Maestro Rechargeable System’s VBLOC vagal blocking therapy as a treatment for obesity

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 conducted a pivotal trial, and believes that the data are positive, leading it to submit the PMA application.

According to the press release, EnteroMedics president & CEO Mark Knudson said that “the Maestro System is a unique, neuroscience-based approach to the treatment of this epidemic disease, one which offers the potential to fill a significant gap in the obesity treatment spectrum. In the hundreds of patients treated to date, in addition to showing clinically meaningful weight loss, VBLOC Therapy has demonstrated an excellent benefit-to-risk profile; a criterion identified by the Agency as central to the review and approvability of new obesity treatment devices.”

NeuroPace is a privately-held company in Mountain View, CA. Their RNS® implantable stimulator, along with depth leads and cortical strip leads are designed for the treatment of medically refractory partial epilepsy.

Unlike Cyberonics’ VNS IPGs, the RNS neurostimulator is designed to detect abnormal electrical activity in the brain and respond by delivering electrical stimulation to normalize brain activity before the patient experiences seizure symptoms. The neurostimulator is implanted in the cranium and connected to one or two leads that are implanted near the patient’s seizure focus.

NeuroPace recently disclosed that it has raised about $18 million of a planned $50 million in new funding. NeuroPace has raised about $180 million since it was founded in 1997.

Mainstay Medical’s Reactiv8 to Treat LBP Caused by Arthrogenic Muscle Inhibition

Posted on by Posted in Mainstay Medical, Muscular Stimulation, Pain, Spinal Cord Stimulation

logo_mainstay1[1]

Mainstay Medical was founded in 2008 by entrepreneur Dr. Danny Sachs. The company’s ReActiv8 neurostimulator is intended to treat chronic low back pain caused by arthrogenic muscle inhibition.  This is a neuroprotective condition in which the brain reflexively attempts to limit motor stimulation and movement in muscles surrounding a joint in response to damage or injury to the joint. In patients with this type of back pain, an initial injury triggers this reflexive inhibition, and the brain tries to limit painful movement by altering nerve transmissions to the deep stabilizing muscles of the spine, causing a loss of motor control, an unstable spine, and greater susceptibility to reinjury.

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.
