BIOTRONIK announced that the U.S. Food and Drug Administration has cleared the Evia® pacemaker for distribution in the U.S., giving physicians and patients access to a unique Bradycardia system designed and manufactured with BIOTRONIK’s unparalleled legacy of quality.

Evia® is the only device that provides a decade of longevity and innovative therapies for physiologic pacing packaged into a device that is 20 percent smaller than our current can size and which has integrated wireless remote monitoring. BIOTRONIK is a leading manufacturer of high-quality implantable cardiac devices and the pioneer of wireless remote monitoring technologies.

Setting the Standard for Remote Monitoring

Evia provides advanced patient management with the complete integration of the clinically proven1 BIOTRONIK Home Monitoring® system. BIOTRONIK introduced home monitoring to the industry almost a decade ago with a system that today monitors, stores data, and provides physicians with early alerts that save lives and prevent hospitalizations. Evia has the unique capability to cellularly transmit required patient and device data, including IEGM Online HD, to perform a complete remote follow-up. It is the world’s smallest pacemaker with integrated wireless remote monitoring. This technology is fully compliant with Heart Rhythm Society and European Heart Rhythm Association device follow-up specifications. Last year, the FDA approved BIOTRONIK Home Monitoring® as the only remote monitoring system on the market that can replace conventional device interrogation during follow-ups.

Quality in every step of the production process

“BIOTRONIK looks forward to providing physicians with the important advancements Evia will bring to their practices. Evia is the latest example of BIOTRONIK’s absolute commitment to deliver quality products designed to enhance patients’ lives,” commented Jake Langer, president, BIOTRONIK U.S.

Evia is the first pacemaker in which all electronic components have been manufactured and tested with full automation, eliminating human touch and minimizing room for human error.

“BIOTRONIK is committed to developing and delivering products like Evia, because quality of life is paramount for patients,” Langer added.

Longevity – A new standard

The REPLACE Registry, sponsored by BIOTRONIK, is a multi-center analysis that quantified complication rates in device replacement procedures utilizing devices from all CRM industry manufacturers. The registry showed that one in 10 patients will suffer side effects and complications from device replacement. “By providing a decade of longevity with Evia, BIOTRONIK again has demonstrated its focus on patient-centric innovations,” stated Langer. “Evia’s new design provides a dramatic reduction in energy consumption. Replacement is safe for most patients, but we have minimized that small risk to a new standard.”

Small Device Delivers Wide Array of Therapy

Evia includes BIOTRONIK’s proprietary and proven Closed Loop Stimulation (CLS), which is the most advanced and physiologic rate regulation algorithm available on the market. CLS integrates into the natural cardiovascular loop by measuring changes in myocardial contraction dynamics and translating them into appropriate heart rate regulation, emulating a healthy sinus node, the human heart’s natural pacemaker. CLS is also the only rate regulation algorithm that is proven to pace effectively during periods of acute mental stress. Intrinsic Optimization (I-Opt), a one-button programming solution, optimizes AV delay with AV hysteresis (up to 400 ms) to minimize right ventricular pacing.

Terumo Medical Corporation, a U.S.-based subsidiary of Terumo Corporation, has announced it has received an investigational device exemption (IDE) conditional approval from the U.S. Food & Drug Administration (FDA) for its Occlusive/Stenotic Peripheral Artery Revascularization Study (OSPREY) in the U.S., which will evaluate the safety and effectiveness of the MISAGO™ Self-expanding Stent System for use in the superficial femoral artery (SFA). This marks the company’s first U.S. clinical trial for a premarket approval (PMA) device. A unique feature of the clinical trial is that it will simultaneously enroll patients in the U.S. and Japan. Referred to as “Medical Device Collaborative Consultation and Review of Premarketing Applications” under the larger “Harmonization by Doing” (HBD) initiative, Terumo’s trial was selected as one of two projects to pilot this approach, which is intended to shorten the gap between product approvals in these two significant world healthcare markets.

HBD is an international effort to develop global clinical trials and address regulatory barriers that may be impediments to timely device approvals. This process is a cooperative effort to move both Japan and the U.S. toward international regulatory harmonization. The HBD initiative is a pilot project launched in December 2003 that seeks regulatory convergence between FDA and MHLW-PMDA (Japan’s regulatory bodies). The learning obtained in the “proof of concept” trials will assist both regulatory bodies in streamlining the clinical trial process for faster approvals in both countries, as well as promote the idea of global trials for purposes of collecting better data. In this pilot HBD approach, the products will be submitted for review and approval at the same time.

“I believe this approach to shorten the time for new product approvals between the U.S. and Japan is critical and exciting,” said Takao Ohki, MD, Chairman and Professor, Department of Surgery, Jikei University School of Medicine, Division of Vascular Surgery, and the global principal investigator of the OSPREY trial. “This innovative movement could dramatically solve the current device lag issue between our countries.”

In the U.S., OSPREY is a single-arm, multi-center, non-randomized prospective clinical trial for the treatment of atherosclerotic stenoses and occlusions of the SFA. In Japan, there are two arms of the study, 50 patients receiving the MISAGO Stent and 50 patients receiving percutaneous transluminal angioplasty (PTA).

The primary endpoints of the U.S. study are:

• Primary stent patency rate at one year as confirmed by duplex ultrasound or angiography.
• Freedom from major adverse events within 30 days of the procedure, which would result in target lesion revascularization, amputation of the treated limb or death.

The study will include up to 350 patients, a maximum of 250 patients in up to 30 centers in the U.S. and 100 patients in Japan. There have already been six patients enrolled in Japan, which received regulatory approval to begin the trial last year. The first U.S. enrollments are expected in June 2010. The U.S. principal investigator is J. Fritz Angle, MD, Associate Professor of Radiology, University of Virginia.

“Peripheral vascular disease management continues to be a major clinical problem,” said Dr. Angle. “We need better tools to improve revascularization of femoral-popliteal vessels. I applaud Terumo’s efforts to advance this field.”

The MISAGO Self-expanding Stent consists of a nitinol stent pre-mounted on the distal portion of a rapid-exchange delivery catheter system. The stent has three radiopaque markers located on each end of the stent to help ensure accurate placement in the lesion. The stent is currently available for sale in Europe.

“We are eager to move forward with the first harmonized clinical trial in the U.S. and Japan,” said Juichi (Jim) Takeuchi, President and CEO, Terumo Medical Corporation. “We are not only proud of the MISAGO Stent, but also of Terumo’s selection to participate in this precedent-setting international collaborative effort between regulators, industry, clinical researchers, patients, and academia. We look forward to initiating our first PMA clinical trial in the United States and to bringing innovative new interventional technology to market to improve patients’ quality of life.”

The U.S. Food and Drug Administration today approved the first medical device that uses radiofrequency energy to treat severe and persistent asthma in certain adults.

The Alair Bronchial Thermoplasty System is intended for patients ages 18 and older whose severe and persistent asthma is not well-controlled with inhaled corticosteroids and long-acting beta agonist medications.

The device is composed of a catheter with an electrode tip that delivers a form of electromagnetic energy, called radiofrequency energy, directly to the airways. A controller unit generates and controls the energy.

Inflammation causes the airways of people who have asthma to swell and narrow, making breathing difficult. The Alair system treats asthma symptoms by using radiofrequency energy to heat the lung tissue in a controlled manner, reducing the thickness of smooth muscle in the airways and improving a patient’s ability to breathe. To benefit, patients will require multiple sessions targeting different areas in the lungs.

“The approval of the Alair system provides adult patients suffering from severe and persistent asthma with an additional treatment option for a disease that is often difficult to manage,” said Jeffrey Shuren, M.D., J.D., director of the FDA’s Center for Devices and Radiological Health.

The FDA based its approval on data from a clinical trial of 297 patients with severe and persistent asthma. The trial showed a reduction of severe asthma attacks with use of the Alair system.

The FDA is requiring a five-year post-approval study of the device to study its long-term safety and effectiveness. The device manufacturer, Asthmatx, will follow many of the patients who were enrolled in the clinical trial and enroll 300 new patients at several medical centers across the United States.

Possible side effects during the course of treatment may include asthma attacks, wheezing, chest tightness or pain, partially collapsed lung (atelectasis), coughing up blood (hemoptysis), anxiety, headaches, and nausea. The Alair system is designed to reduce the number of severe asthma attacks on a long-term basis. However, there is a risk of immediate asthma attacks during the course of the treatment.

The Alair system is not for use in asthma patients with a pacemaker, internal defibrillator, or other implantable electronic device. Also, those patients with known sensitivities to lidocaine, atropine, or benzodiazepines should not use the device. Alair has not been studied for success in retreatment of the same area of the lung. Currently, patients should not be retreated with the Alair system in the same area of the lung.

Asthma patients considering the Alair system should not be treated while the following conditions are present: an active respiratory infection, coagulopathy (bleeding disorder), asthma exacerbations, or if they have had changes to their corticosteroid regimen 14 days before the proposed treatment.

Asthmatx Inc. is based in Sunnyvale, Calif.
