An advanced blood test uses a blood sample, digital microscope, and an image-processing algorithm to distinguish suspect circulating tumor cells (CTCs) from healthy cells — a method that could yield information comparable to some types of surgical biopsies, according to findings from five new...

You just never know what will get the creative juices flowing. It could be a slight aberration from your morning routine. Or it could be something as basic as the entree you order at dinner. The latter is actually what inspired the invention of a crab-like miniature robot that could help surgeons remove early-stage...

Since it was established 11 years ago, the Stanford Biodesign Innovation Program has led to more than 200 patents and 24 start-up companies, including Spiracur, the company behind the SNaP Wound Care System (featured in the January issue of Medical Design Briefs). This intensive one-year program helps...

Researchers have made T-rays into a much stronger directional beam than was previously thought possible — and have done so at room-temperature conditions. This is a breakthrough that should allow future T-ray systems to be smaller, more portable, easier to operate, and much cheaper than...

The process of monitoring blood glucose levels through finger pricking is an inconvenience at best for the estimated 26 million diabetics in the U.S. It's no mystery why researchers have continued to set their sights on developing more convenient and less invasive methods of monitoring glucose...

From delivering care to the developing world, to remote echocardiography, to hearing assessment, telemedicine has opened doors to new and potentially improved forms of diagnosis and treatment. Dermatology is one area in particular that stands to benefit greatly from this technology.

Raven II, a robotic surgery system developed at UC Santa Cruz and the University of Washington, is being shared on an open-source basis with five other universities. Researchers hope that this will enable users to share software, replicate experiments, and collaborate in other ways — and ultimately...

A Microsoft Research Connections project proposes to develop a contact lens that monitors blood glucose levels for type 1 diabetes patients. Other non-invasive alternatives to the finger-pricking method have also been explored elsewhere — such as this tear-based glucose sensor from Arizona State University,...

The road to better, longer-lasting hip implants may be paved with better lubricants. A team of engineers and physicians recently discovered that graphitic carbon is a key element in a lubricating layer for longer-lasting metal-on-metal hip implants. The ability to extend the life of implants would have enormous...

Engineers at the University of Illinois have developed a bandage that stimulates and directs blood vessel growth on the surface of a wound. The bandage, called a “microvascular stamp,” contains living cells that deliver growth factors to damaged tissues in a defined pattern. The new approach is the...

The FDA recently announced an initiative to improve reusable medical device reprocessing, the process of cleaning and disinfecting a device for use with more than one patient. Improper reprocessing of reusable medical devices can lead to Health care-Associated Infections (HAIs). Medical Design Briefs will explore this...

Time and again, gaming technology has proven its ability to benefit our lives in ways that surpass entertainment. It has been utilized in medical and therapeutic applications ranging from helping stroke victims restore functionality, to training users to control stress and multi-task. Another example recently came to my...

Promising news for millions of Americans living with type 1 diabetes: The FDA has issued guidelines specific to developing an artificial pancreas — a system that would serve to continuously monitor blood glucose levels and deliver the correct amount of insulin to the body when needed, functioning...

A team of researchers co-led by the University of Pennsylvania has developed and tested a high-resolution, ultra-thin device capable of recording brain activity from the cortical surface without having to use penetrating electrodes. The device could open the door to a new generation of...

Systems for monitoring vital signs while driving could help measure stress levels, among other health parameters — effectively "driving" the concept of multi-tasking to a new level. By integrating sensors into the steering wheel, scientists at TU Muenchen Chair of Micro Technology and Medical Device Technology (MiMed) have...

3D printers have the potential to quickly produce complex structures and materials — including bone scaffolds, if Washington State University scientists have their way. An interdisciplinary team of chemistry, materials science, biology, and manufacturing researchers produced a bone-like material using a 3D printer.

Swedish researchers at Chalmers University are developing new techniques of cancer diagnosis and treatment that utilize the power of microwaves. One method is an alternative to mammography. The other method aims to treat tumors by heating the cancer cells. Eventually, they hope to combine the two methods into one...

In yet another example of how medical technology designed for humans in space can also benefit humans on Earth, Radisens Diagnostics (Cork, Ireland) recently announced that it will be working with the European Space Agency to develop a blood testing device. According to the press release, the ESA contracted the...

In 2009, the first wireless pacemaker was implanted in a patient in the U.S., but there is still a lot of work that remains to be accomplished. About a year ago, Medtronic offered a sneak peek of a leadless pacemaker under development, and other medical device firms and startups have also announced similar...

Aneurysms can occur in any blood vessel in the body and usually cannot be detected unless there is a rupture or leakage. About 33,000 North Americans suffer a rupture every year, leading to stroke with up to a 60 percent fatality rate and permanent disability in about 50 percent of survivors. Now,...

A team of computer scientists, physicists, and physicians at Harvard have developed a simple yet powerful method of visualizing human arteries that may result in more accurate diagnoses of atherosclerosis and heart disease. The prototype tool, called “HemoVis,” creates a 2D diagram of...

The magnetic resonance imaging process usually requires patients to lie still in the machine for up to 45 minutes. Now, that scan time could be cut to just 15 minutes, with a newly developed algorithm from MIT's Research Laboratory of Electronics.

A recent patient study from Cambridge Consultants indicates user experience and satisfaction are particularly important in the success of drug delivery and combination devices. Furthermore, investing time and effort into increasing the ease-of-use of these devices can pay off — 77% of patients...

Imagine a smartphone that could act as your counselor in stressful situations, advising you on how to measure and deal with stress in your life. Researchers at Cornell University are developing just such an application, and their work is just one example of hopefully many projects that will come out...

Researchers at Cornell are exploring the possibilities of a well-established imaging technology called multiphoton microscopy, as they work toward developing a next-generation endoscope that would minimize the need for biopsies altogether, and also allow doctors to examine surgical margins at high...

Researchers from the National Institute of Standards and Technology (NIST) and University of Colorado Boulder (CU) have developed a low-power microchip that uses a combination of microfluidics and magnetic switches to trap and transport magnetic beads. This chip may have applications in biotechnology and...

The concept of a "one size fits all" medical device sounds attractive in theory, but in practice, it isn't very likely that one device can be developed to meet every patient's unique needs. This is particularly true when it comes to pediatric devices, which may not receive as much attention or funding as...

A team of researchers from the University of California, Davis has transformed everyday iPhones into medical-quality imaging and chemical detection devices. Though they are not the first to tweak the smartphone in this way, this represents a simpler and more affordable method. Using materials...

The same piezoelectric effect that ignites a gas grill could one day power sensors in the body via human respiration. Researchers at the University of Wisconsin-Madison are using polyvinylidene fluoride (PVDF), a piezoelectric polymer, to develop a host of biomedical devices that could monitor blood...
