Medtronic announces clinical data on new cardiac pacemakers

The famous medical technology company Medtronic can be said to be a happy event. The company's new defibrillator equipment has recently been approved by the FDA. Recently, the company announced the latest research data of its new lead-free pacemaker Micra at the Heart Rhythm Society Conference in San Francisco. The data shows the stability and good performance of this new device after being implanted in patients for several months. The safety, it is worth noting that this device still shows good performance under extreme conditions.

In a three-month and six-month study of 20 patients, the researchers found that the product still had good heart rate regulation even in the maximum power cycling test. It ensures that the heart rate of patients with bradycardia during exercise can rise normally with the intensity of training.

The researchers say that traditional pacemakers can only detect patient activity through sensors distributed outside the patient's heart to regulate heart rate, but this method is difficult to accurately detect moderate-intensity exercise. With sensors built into the heart, the Micra pacemaker's detection efficiency is greatly improved, thus providing more accurate protection for patients.

On the other hand, the new pacemaker of Micra is about the same size as a tablet, only one-tenth the size of a conventional pacemaker. Existing research shows that 99.2% of patients have successfully implanted this product.

In addition, at this conference this week, EBR Systems also released clinical research data for its new pacemaker Wireless Stimulation of the Endocardium (WISE) System in Europe. In this study, the researchers recruited 39 patients who were unable to use other pacemaker products to receive treatment for the WISE system. The results showed that 34 patients had improved condition. However, unlike products from Medtronic and St.Jude Medical, this device is implanted in the patient's left ventricle.
