We've already heard how electrical pulses have been shown to help heal wounds, by promoting tissue growth. An experimental new implant uses that same principle to aid in the regeneration of cardiac tissue, potentially postponing or even eliminating the need for heart transplants.

Over the past several years, we've heard about a number of implantable devices that regularly dispense medication within the body, doing away with the need for pills or injections. A new one takes things further, as its dosage level can be changed after it's been implanted.

For some time now, we've been hearing about implantable scaffolding-like material that helps heal injuries to bones. Scientists have now developed a new type of that material, aimed specifically at difficult-to-treat osteochondral injuries.

Although joint replacement surgery typically goes off without a hitch, potentially-dangerous infections can occur after the operation. Scientists from New Jersey's Stevens Institute of Technology are addressing that problem, with a new type of highly-targeted bacteria-killing gel.

Scientists at Columbia University have developed flexible, functional, waterproof transistors. These could find use in building miniaturized medical sensors, brain-machine interfaces, or long-term implants.

It was just last month that we heard about a brain implant which dispenses a protein to stop seizures in epileptic rats. An unrelated study now suggests that a brain implant in humans, which delivers that same protein, could be used to treat and even reverse the effects of Parkinson's disease.

Resulting from bone-breaks, deep puncture wounds, severe tooth decay or other causes, osteomyelitis is a bone infection that in serious cases may lead to amputations or even death. It's also notoriously difficult to treat, although a newly-developed implant could help change that.

When a young person receives an artificial knee joint, they're left in a bit of a quandary – they're expected to stay active, yet too much of the wrong activity may cause the device to wear out prematurely. An experimental new implant could help address that situation.

There may be new hope for people who suffer from epilepsy. A recent study has shown that an experimental implant reduces seizures in epileptic rats by 93 percent, and that the effects remain after the device has been removed.

When someone has had blood vessel surgery, it's important for doctors to check that the vessel doesn't become blocked as it heals. Such blockages could someday be detected earlier and more easily than ever, thanks to an experimental new biodegradable blood flow sensor.
