Implant

Researchers at UCLA have developed a small sponge that can be implanted next to a tumor to help the body fight it. In tests in mice, the devices induced remission, prevented growth and spread of cancers, and increased survival times.

While islet cell transplants allow some diabetics to forgo daily insulin injections, those people must take immunosuppressive drugs to protect those cells. A new implant, however, could administer the drugs for them, with fewer side effects.

It's a sad fact that people with conditions such as muscular dystrophy and ALS often have difficulty breathing, as their diaphragm muscle doesn't work properly. MIT scientists have set out to give that muscle a boost, with an implantable ventilator.

The installation of a cochlear implant is a tricky procedure, in which certain nerves may be damaged if the surgeon isn't careful. A new "smart" surgical drill is designed to help, by automatically shutting off if it gets too close to those nerves.

We hear a lot about artificial hips and knees, but finger joints? They do exist, but their fit and functionality is limited. Germany's Fraunhofer research group aims to change that, with artificial finger joints that are 3D-printed for each patient.

Researchers have developed an implantable pump that can deliver chemotherapy drugs directly into the brain to fight hard-to-treat cancer. In a phase 1b trial, patients were able to undergo the therapy while going about their day-to-day activities.

When a limb is rendered immobile for long periods of time, its muscles will inevitably begin to atrophy. A new implant could help keep that from happening, however, by mechanically stretching and compressing those muscles.

Currently, small metal implants either have to be surgically removed from the body once they're no longer needed, or just left inside indefinitely. Now, however, scientists have devised a method of breaking them down in place using liquid metal.

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.
