Reveal LINQ: Medtronic’s New Miniaturized Insertable Cardiac Monitoring System
Medtronic’s new Reveal LINQ Insertable Cardiac Monitor is a tiny implantable device that weighs less than three grams and is far less invasive than any previous loop recorder. The figure above shows its diminutive size compared to the Reveal XT device – it is a full 87% smaller!
The Reveal LINQ is a leadless device that is implanted in the region of the thorax by way of a <1cm incision. Two electrodes on the body of the device continuously monitor the patient’s subcutaneous ECG. The device stores ECG recordings from the patient-activated episodes and ECG recordings from automatically detected arrhythmias.
Reveal LINQ stores a total of 57 minutes of ECG, including 27 minutes of automatically-detected episodes and up to 30 minutes of patient-activated recordings with 6.5–14 min. buffers.
The device connects wirelessly with Medtronic’s MyCareLink™ Patient Monitor, making the Reveal LINQ ICM the only ICM to collect and trend data continuously and wirelessly.
Medtronic Performs First Human Implant of its Micra Leadless Pacemaker
According to the press release:
At one-tenth the size of a conventional pacemaker, and comparable in size to a large vitamin, the Micra TPS is delivered directly into the heart through a catheter inserted in the femoral vein. Once positioned, the pacemaker is securely attached to the heart wall and can be repositioned if needed. The miniature device does not require the use of wires, known as “leads,” to connect to the heart. Attached to the heart via small tines, the pacemaker delivers electrical impulses that pace the heart through an electrode at the end of the device.
Sorin Announces CE Mark and Implant of its MRI-Compatible Kora 100 Pacemaker with Automatic MRI Mode
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.

St. Jude Studies Combined PNFS and SCS for Chronic Low Back and Leg Pain
St. Jude announced today that it has launched the SENSE™ Subcutaneous and Epidural Neuromodulation System Evaluation study – a clinical study to evaluate the combination of peripheral nerve field stimulation (PNfS), and spinal cord stimulation (SCS), to determine whether the two therapies together offer more effective management of chronic low back and leg pain than SCS alone.
According to the press release:
Peripheral nerve field stimulation and SCS are minimally-invasive neurostimulation therapies that involve the implant of a stimulation device and small electrical leads. In SCS, leads are placed in the epidural space to interrupt or mask the transmission of pain signals to the brain. In PNfS, leads are placed just under the skin in the subcutaneous tissue to stimulate the network of peripheral nerve fibers in order to reduce the pain at the location where it is most severe. PNfS is not the same as peripheral nerve stimulation (PNS), which targets a specific nerve. Instead, PNfS targets a more general network of nerves.
St. Jude Launches SUNBURST Study to Evaluate New Prodigy Neurostimulator’s Burst Stimulation for Chronic Pain
St. Jude announced today that it has initiated a clinical study of the Prodigy™ neurostimulator, which is the first SCS system able to deliver a proprietary mode of stimulation therapy called burst stimulation.
The purpose of the SUNBURST™ (Success Using Neuromodulation with BURST) study is to evaluate whether burst stimulation can be more effective in managing chronic pain than traditional tonic stimulation.

Cerbomed’s Non-Invasive Vagus Nerve Stimulator Poses Challenge to Implantable VNS Systems
Cerbomed GmbH, located in Erlangen, Germany, was founded in 2005 to develop transcutaneous Vagus Nerve Stimulation (t-VNS®) neuromodulation systems.
Surgically accessing the Vagus Nerve is not trivial, and implanting a VNS system involving cuff electrodes is risky and recovery is lengthy. Enter t-VNS, which is delivered non-invasively to the auricular branch of the vagus nerve (ABVN), making it an attractive therapy option when compared to implantable vagus nerve stimulators.
The NEMOS tVNS system consists of a handheld stimulator and a dedicated ear electrode, which patients wear like an earphone. According to Cerbomed, intensity, pulse duration and frequency of the t-VNS stimulation have been optimized to induce signals in thick-myelinated Aβ fibres of the ABVN. Like those of the cervical branch of the vagus nerve, these project directly to the nucleus of the solitary tract (NTS) in the brainstem.
In 2010 Cerbomed received the CE mark for its NEMOS® transcutaneous Vagus Nerve Stimulator for the treatment of epilepsy and depression. In 2012, the indication was expanded to include the treatment of pain.
In September 2012, Cerbomed entered into a strategic partnership with Cyberonics, Inc., the global market leader in vagus nerve stimulation. Cyberonics made an initial investment of €2 million to fund Cerbomed’s epilepsy clinical trial in Germany, with further investments of up to €5.5 million, subject to the achievement of certain clinical milestones. Cyberonics is a minority shareholder with certain rights, including representation on Cerbomed’s advisory board and an exclusive option for worldwide sales and distribution of NEMOS.
Abrupt Increase in Thoratec HeartMate II LVAD Thrombosis Reported in NEJM
A study published on Nov 27, 2013 in the New England Journal of Medicine reports on a sudden increase in the incidence of pump thrombosis with the Thoratec HeartMate II LVAD.
The study shows an unexplained increase in thrombosis when comparing LVAD patients at three centers from January 2004 to March 2011 vs. those implanted March 2011 to April 2013. During these periods, the rate of confirmed thrombosis three months after LVAD implantation increased sharply from 2.2% to 8.4%, and median time from implantation until the development of blood clots with the devices decreased from 18.6 to 2.7 months. The increasing incidence of early thrombosis with the HeartMate II is reported to be associated with substantial morbidity and mortality.
The study was initiated by the outcome of a quality review whereby the Cleveland Clinic detected an unexpected abrupt increase in the incidence of device thrombosis. The results were reported to Thoratec and the FDA. To confirm these findings, implant data were reviewed for 895 HeartMate II devices implanted in 837 patients from 2004 to 2013 at the Cleveland Clinic, Washington Barnes-Jewish Hospital, and Duke University Medical Center. The frequency of device thrombosis increased steeply around March 2011 at the three institutions.
Dr. Randall C Starling (Cleveland Clinic, OH), the first listed author, told heartwire that the research groups are working with the Thoratec to try to identify an explanation for this issue.
