Implant

Treatments for osteoarthritis-related knee pain range from medication all the way up to knee joint replacement. The recently trialled Misha Knee System is intended to help fill the gap between those extremes, by acting as an implanted shock absorber.

Nobody wants to suffer physical pain if they don't have to, yet they also don't want to risk developing an addiction to pain-killing opioids. That's where a new drug-free implant comes in, as it reduces pain by cooling nerves.

There may soon be new hope for patients born with genetic defects that leave them with misshapen or missing ears. A new human clinical trial will test an implant known as an AuriNovo, which uses a 3D-bioprinted ear grown from the patient’s own cells.

Scientists experimenting with the makeup of metal alloys used for medical implants have made a significant breakthrough, resulting in a biomaterial with the flexibility and wear resistance needed for long-term stints in the human body.

Last year, scientists at Northwestern University announced a transient pacemaker that dissolves when no longer needed. They've now improved the device, and incorporated it into a linked suite of wearable sensors.

Arkenlight and Axorus have teamed up to prototype the first artificial neuron powered by a diamond betavoltaic battery made from nuclear waste. The goal is to develop medical-grade implants with energy sources that will last decades without charging.

Stents can make a life-saving difference for people with vascular problems, as they open up narrowing blood vessels. An experimental new one goes a step further, by actually transmitting blood flow data to an external computer or mobile device.

Powering medical implants can be tricky, but tapping into the body’s own fuel source could keep them going long-term. A new design for a tiny fuel cell converts glucose into electricity to power implants more efficiently than any other so far.

When treating patients for certain conditions, it's important to monitor their blood oxygen levels. A new sub-dermal photosensitive sensor provides a new means of doing so, plus it could one day be used to measure other blood-borne substances.

Scientists regularly turn to nature for inspiration in their pursuit of next-generation materials, and engineers studying the porous microstructures of bone and wood have come up with a clever example of biomimicry with wide-ranging potential.

When a pacemaker's battery gets low, the whole implant typically has to be surgically replaced. Scientists are therefore developing a noninvasive battery recharging system, which utilizes externally applied ultrasound.

By taking ultrathin films and color pigments used routinely in the food industry, scientists have developed an implantable device that can be activated by light to stimulate nerve cells and accelerate healing.
