And as medical machines and the computers that power them become smaller, faster, and smarter, the medical device industry is making medical practice easier for doctors, more effective for patients, and cheaper for the entire healthcare system.
Wireless technologies capable of detecting and treating the earliest signs of disease will become front-line defenses against these leading causes of death, while devices that help patients manage their own chronic conditions more effectively will dramatically improve their quality of life while reducing the demand for more advanced treatments, he said.
Consumer-friendly wearable or unobtrusive monitors comprising a range of sensors and communications devices. Pomager identified several industry collaborations between large device developers and technology companies to incorporate a wide range of medical measurements in simpler devices. For a sense of how these trends are manifesting themselves today, here is a selective overview of five of the most talked-about directions in medical device technologies of the past year.
That translates into better patient outcomes, lower healthcare costs, and wider access to healthcare services in under-resourced parts of the world. Medical nanodevices and materials are already in widespread use. Inorganic nanoparticles of materials synthesized from metals such as gold or silver and ranging in size from 1 to nm are commonly used as contrast agents in in vivo tumor imaging and as molecular probes for the study of cellular or subcellular function.
Quantum dots fabricated from semiconductor materials are similarly valued as alternatives to fluorescent proteins, organic dyes, or radioisotopes. Also for you: 5 Innovative Medical Technologies. But not all medical applications of nanoparticles are as passive as these imaging tools.
In fact, emerging cancer treatment technologies employ nanomaterials in ways that are not merely hands-on, but downright aggressive. The nm devices are made from single strands of DNA folded into a desired shape — for instance, a clamshell-shaped package that protects a drug while en route to the desired site but opens up to release it upon arrival. Led by Bar-Ilan professor Ido Bachelet, the team has so far developed DNA robots that can recognize 12 different cancer cell types, and is now working to program swarm behavior into bots designed to physically bond in the body for the other applications such as tissue or nerve repair.
A similar targeted approach developed by University of California-San Diego nanoengineers Joseph Wang and Sadik Esener uses a so-called microcannon to blast a tumor with anti-cancer drugs with dead-eye precision. Their approach uses ultrasonic waves to guide the nanoparticles to their destination, trigger the release of their therapeutic payload, and make the selected tissue more permeable to the drug.

They fashioned their 5-micrometer microcannon from a porous membrane coated with graphene oxide and gold. For ammunition, they encased 1-micrometer silica particles in a liquid gel containing perfluorocarbon PFC as a propellent. The PFC vaporizes when exposed to pulsed ultrasonic waves, producing gaseous microbubbles that expand rapidly to propel the nanobullets toward their target. In his State of the Union Address, President Obama called for a renewed focus on the development of more advanced artificial limbs and other prosthetic devices. At least , Americans live with an upper-arm amputation, and 6 million others are paralyzed.
These brain-machine interface BMI technologies have advanced rapidly since their highly publicized debut. Although many approaches involve the direct implant of a sensor into the brain itself, newer research focuses on the use of external devices such as headsets to relay brain signals to limbs, wheelchairs, or other assistive technologies. One novel twist on paralysis repair seeks to regenerate damaged spinal cord tissue with spinal implants made of multifunctional polymer fibers, each thinner than a human hair.
