A new generation of implantable medical devices, a new hot spot in global medical research and development

Business Agency, March 14
the implantable medical device industry has made remarkable progress over the past 30 yearsFrom implantable pacemakers, implantable atrial defibrillators, cochlear implants, implantable electrodes (for the treatment of Parkinson's disease, epilepsy and other diseases), implantable insulin pumps, to a variety of implantable vascular stents, these products will soon become the best-selling products in the medical device marketTo be sure, implantable medical devices have become an important branch of medical devicesin recent years, the development of a new generation of implantable medical devices in the United States and other developed countries have developed in full swing, such as wireless heart monitor, real-time blood glucose monitor, remote life monitor, implantable cancer detector and so onThese medical devices, which are already on the market or in clinical trials, are more dexterous and convenient in form factor or use, saving medical costs and providing better outcomes, and even timely prediction of diseaseimplantable cancer detector
According to a recent report in The American Journal of Science, cancer incidence is on the rise in countries around the worldHow to accurately judge the efficacy and progression of the tumor after chemotherapy, radiotherapy or surgery is a difficult problemResearchers at the Massachusetts Institute of Technology have developed an implantable cancer detector that is less than 5 mm in diameter and contains nanoprotein particles such as testosterone (androgen)After the product is implanted into patients with malignant tumors such as testicular cancer and ovarian cancer, a special protein secreted by active tumor tissue in large quantities binds to these nanoparticles and becomes metamorphosisDoctors use an MRI device to scan the patient's body cancer detector, you can intuitively understand the patient's body tumor activity on the display screen, and accordingly develop the appropriate treatment planimplantable glucose monitorZyvex Nanotechnology, Inc., a company specializing in the development of nano-biosensor technologyThe company has developed an implantable blood glucose monitor that is the size of a normal button battery The product can generate a corresponding weak biological current based on human blood sugar levels, and measured biological current changes in the form of data through the micro-silicon semiconductor chip sent to the information terminal, so that doctors and patients can know blood glucose data in real time The product has entered clinical trials a new implantable glucose sensor developed by GlySens of the United States to provide wireless testing for people with diabetes This device continuously monitors the patient's subcutaneous glucose levels The device provides more accurate and complete information than the method of monitoring blood collection at the fingertips, which can guide the injection dose and time of insulin in , a Finnish company has developed a new type of implantable insulin pump specifically for people with type I diabetes According to the developers, the implantable insulin pump can automatically regulate the dose of insulin administration according to changes in blood sugar in diabetic patients implantable health information recorder
high blood pressure , coronary heart disease, diabetes, chronic obstructive pulmonary disease and other "slow disease" has caused governments to attach great importance to predicting the occurrence of diseases" or monitoring disease changes, can enable people to prevent, diagnose and treat diseases as soon as possible, or avoid sudden events in recent years, foreign manufacturers have stepped up the development of implantable electronic health information recorder According to foreign research and development personnel, these implantable instruments can record the human heart rate, blood pressure, pulse, blood sugar and oxygen saturation and other important life and health information in real time, and wireless transmission of data to the data terminal, so that doctors can timely grasp the patient's vital signs changes Most of these new products combine new technologies such as nanotechnology, microelectronics and chip technology " Longevity battery "
at present, in addition to vascular stents and a few other implantable medical device products, the vast majority of implantable medical devices need to use power, button batteries are implantable electronic medical devices used in one of the most power However, the maximum life of a regular button battery is 3 to 5 years, which means that once the power is exhausted, the patient must have another operation to remove the implantable electronic medical device to replace the new battery According to foreign media reports, Canada's Eagle Pitcher has developed the world's smallest "longevity" miniature battery dedicated to implantable electronic medical devices It is about 0.26 inches in size and discharged for up to 15 years, more than three times the existing coin cell Installing it in implantable electronic medical device such as implantable pacemakers, implantable atrial defibrillators, and implantable insulin pumps can greatly extend the useful life of these products and reduce or even avoid the pain of secondary surgery
