Nowadays medical technology companies are focusing more than ever on products that deliver cheaper, faster, more efficient patient care. They are also making inroads with U.S. Food & Drug Administration regulators to re-engineer the complex review and approval process for new medical devices.
Every year, industry observers like the Cleveland Clinic and the medical device trade press single out their favorite technology trends. These thought leaders agree that today’s best technologies strike a balance between reducing the overall cost of medical care and increasing safety and survival rates—and isn’t that what health care reform is all about? Check out the following top 4 medical innovations, that changed the future in a big way.
Electronic Aspirin
For people who suffer from migraines, cluster headaches, and other causes of chronic, excruciating head or facial pain, the “take two aspirins and call me in the morning” method is useless. Doctors have long associated the most severe, chronic forms of a headache with the sphenopalatine ganglion (SPG), a facial nerve bundle, but haven’t yet found a treatment that works on the SPG long-term. A technology under clinical investigation at Autonomic Technologies, Inc., is a patient-powered tool for blocking SPG signals at the first sign of a headache. The system involves the permanent implant of a small nerve stimulating device in the upper gum on the side of the head normally affected by a headache. The lead tip of the implant connects with the SPG bundle, and when a patient senses the onset of a headache, he or she places a handheld remote controller on the cheek nearest the implant. The resulting signals stimulate the SPG nerves and block the pain-causing neurotransmitters.
Needle-Free Diabetes Care
Diabetes self-care is a pain—literally. It brings the constant need to draw blood for glucose testing, the need for daily insulin shots and the heightened risk of infection from all that poking. Continuous glucose monitors and insulin pumps are today’s best options for automating most of the complicated daily process of blood sugar management – but they don’t completely remove the need for skin pricks and shots. But there’s new skin in this game. Echo Therapeutics is developing technologies that would replace the poke with a patch. The company is working on a transdermal biosensor that reads blood analytes through the skin without drawing blood. The technology involves a handheld electric-toothbrush-like device that removes just enough top-layer skin cells to put the patient’s blood chemistry within signal range of a patch-borne biosensor. The sensor collects one reading per minute and sends the data wirelessly to a remote monitor, triggering audible alarms when levels go out of the patient’s optimal range and tracking glucose levels over time.
Cutting Back on Melanoma Biopsies
With the most deadly form of skin cancer, melanoma, a huge number of dangerous-looking moles are actually harmless but has always been impossible to know for sure without an invasive surgical biopsy. Today dermatologists have new help in making the right call — a handheld tool approved by the FDA for multispectral analysis of tissue morphology. The MelaFind optical scanner is not for definitive diagnosis but rather to provide additional information a doctor can use in determining whether or not to order a biopsy. The goal is to reduce the number of patients left with unnecessary biopsy scars, with the added benefit of eliminating the cost of unnecessary procedures. The MelaFind technology uses missile navigation technologies originally paid for the Department of Defense to optically scan the surface of a suspicious lesion at 10 electromagnetic wavelengths. The collected signals are processed using heavy-duty algorithms and matched against a registry of 10,000 digital images of melanoma and skin disease.
Changing a heart valve
The Sapien transcatheter aortic valve is a life-saving alternative to open-heart surgery for patients who need new a new valve but can’t endure the rigors of the operation. Manufactured by Edwards Life Sciences, the Sapien has been available in Europe for some time but is only now finding its first use in U.S. heart centers—where it is limited only to the frailest patients thus far. The Sapien valve is guided through the femoral artery by catheter from a small incision near the grown or rib cage. The valve material is made of bovine tissue attached to a stainless-steel stent, which is expanded by inflating a small balloon when correctly placed in the valve space. A simpler procedure that promises dramatically shorter hospitalizations is bound to have a positive effect on the cost of care.
