CardioMEMS miniature implantable sensor for heart failure and aneurism management

Although the FDA advisory panel found CardioMEMS’ CHAMPION HF Pressure Measurement System to be safe, on October 9, 2013, the majority of panel members decided that the implantable sensor monitor to help guide treatment in patients with congestive heart failure is not effective.

According to Forbes, one panel member said it was difficult to connect the dots between use of the monitor and decreased hospitalization and lack of data on use in women.

This is not the first time that CardioMEMS attempts to receive PMA approval.  In 2011 FDA rejected the Champion implantable monitoring system for heart failure for premarket approval, in part due to questions about the validity of presented data. Last year, CardioMEMS received an FDA Warning Letter.

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:

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.

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.

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.
