ST. PAUL, Minn.--(BUSINESS WIRE)--St. Jude Medical, Inc. (NYSE:STJ), a global medical device company, today announced the first U.S. implant in the company’s LEADLESS II pivotal trial designed to evaluate the Nanostim™ leadless pacemaker for U.S. Food and Drug Administration (FDA) approval. The world’s first retrievable, non-surgical pacemaker was implanted at The Mount Sinai Hospital in New York City by Dr. Vivek Reddy.
The Nanostim leadless pacemaker is designed to be placed directly in the heart without the visible surgical pocket, scar and insulated wires (called leads) required for conventional pacemakers. Implanted via the femoral vein with a steerable catheter, the device offers physicians the same pacing therapy through a less-invasive approach as compared to traditional pacemaker procedures that require more extensive surgery. The device is designed to be fully retrievable, so that it can be readily repositioned throughout the implant procedure and later retrieved if necessary.
“This clinical research trial will be testing the latest innovative, non-surgical pacemaker option for U.S. patients experiencing heart rhythm issues,” said the study’s co-investigator Dr. Vivek Reddy, Director of Electrophysiology Services at The Mount Sinai Hospital and Chairman of the Steering Committee of the study. “This new-age, tiny pacemaker may ultimately be safer for patients because it doesn’t have leads or have to be inserted under the skin of a patient’s chest, like a traditional cardiac pacemaker. I believe this pioneering, compact device, which is placed directly inside the heart, may be a true game-changing technology in cardiovascular medicine and may help revolutionize care for patients with arrhythmias. I look forward to the results of the LEADLESS II clinical trial.”
The Nanostim leadless pacemaker is less than 10 percent the size of a conventional pacemaker and is the least invasive pacing technology available today. The small size of the device and lack of a surgical pocket, coupled with the exclusion of a lead, improves patient comfort and may reduce complications, including device pocket-related infection and lead failure. The elimination of the visible lump and scar at a conventional pacemaker’s implant site, in addition to the removal of patient activity restrictions that are routinely put in place in an attempt to prevent dislodgement or damage to a conventional lead, will potentially improve the quality of life for patients with this technology by allowing most to continue living active, uninhibited lifestyles. The device is supported by the St. Jude Medical Merlin™ Programmer, which is also used to interrogate and program the company’s other pacemakers and implantable cardioverter defibrillators (ICDs).
“Since the introduction of the first implantable pacemaker in 1958, pacemaker technology has continued to evolve into smaller, more efficient devices,” said Dr. Mark D. Carlson, chief medical officer and vice president of global clinical affairs for St. Jude Medical. “Despite this evolution, pacing technology has, until now, required surgery in addition to leads that connect the pacemaker to the heart. The Nanostim leadless pacemaker is the first miniaturized device that removes the need for leads, thus offering less invasive and less complicated procedures for physicians and patients around the world. We believe the innovative nature of this technology will change the future landscape of cardiac rhythm management devices by revolutionizing the delivery methods and design of these life-saving technologies.”
Cardiac pacemakers are used to treat bradycardia, which is a heart rate that is too slow. These devices monitor the heart and provide electrical stimulation when the heart beats too slowly for each patient's specific physiological requirements. More than 4 million people worldwide have an implanted pacemaker or other cardiac rhythm management device, and an additional 700,000 patients receive the devices each year.
LEADLESS II Clinical Trial Design
The LEADLESS II pivotal trial is a prospective, non-randomized, multi-center, international clinical research trial designed to evaluate the safety and effectiveness of the Nanostim leadless pacemaker in patients indicated for the device. It is being conducted under an Investigational Device Exemption (IDE) from the FDA, and will enroll approximately 670 patients at 50 centers in the U.S., Canada and Europe.
LEADLESS Clinical Trial Preliminary Results
Initial results from the LEADLESS study, a prospective, single-arm, multicenter study evaluating patients with the Nanostim leadless pacemaker, were presented last year and demonstrated overall device performance comparable to conventional pacemakers. Total implant procedure times averaged 28 minutes. Even with miniaturization, the device battery is expected to have an average lifespan of more than nine years at 100 percent pacing, or more than 13 years at 50 percent pacing.
The Nanostim pacemaker received CE Mark approval in 2013 and is available in select European markets. The device is not available for sale in the U.S.
