Implant

A team of researchers from MIT has discovered that creating body implants at a certain size maximizes the amount of time they can spend operational in the body before being neutralized by the immune system. In the future, the research could lead to longer term treatment avenues for diseases that could do away with the need for painful and repeated injections.

When a vein or artery gets seriously blocked, a common course of action involves replacing it with part of another blood vessel harvested from elsewhere in the patient's body. While 3D-printed and lab-grown blood vessels show promise as alternatives, scientists from the Vienna University of Technology and Vienna Medical University have developed another option – polymer fabric vessels that transform into biological ones, once implanted.

While there are a large number of approved cancer treatments, identifying which drugs are best suited to individual patients is extremely difficult for doctors. A team of MIT researchers has developed a small, implantable device that aims to change this by allowing scientists to measure the effectiveness of different drugs, on a patient-by-patient basis.

Two years ago we heard about the Nanostim, a pacemaker that's less than 10 percent the size of a regular model. While it's pretty darn small, Medtronic's just-announced Micra TPS (Transcatheter Pacing System) is reportedly even tinier. Billed as the world's smallest pacemaker, it's described as being the size of a large vitamin capsule – and it can be implanted using a catheter. Read More
In the near future, it's entirely possible that babies with heart defects will be born with complete pacemakers already installed. That's because scientists at Children's Hospital Los Angeles (CHLA) and the University of Southern California have developed the world's first fully-implantable pacemaker for fetuses. Read More
Whenever foreign objects such as catheters, implants or other devices are placed within the human body, there's a danger that bacterial colonies known as biofilms could collect on them, leading to infections. Now, however, scientists at Harvard University's Wyss Institute have created a material that's too slippery for those biofilms to cling onto. It works by continuously releasing oil. Read More
In order to study how young fish such as salmon are affected by swimming through hydroelectric dams, scientists have traditionally equipped them with surgically-implanted acoustic tracking tags. Unfortunately, the implantation procedure can harm the fish, plus the weight of the device can affect their behavior. Now, however, a team at the Pacific Northwest National Laboratory (PNNL) in Washington state has developed a much lighter acoustic tag, that can be injected into fish using a needle. Read More
EnteroMedics' Maestro System has become the first obesity device to be approved by the United States Food and Drug Administration in ten years. The device, which the company compares to a pacemaker, is designed to block signals in the nervous system to reduce feelings of hunger. Read More
Three years ago, scientists at the Swiss Federal Institute of Technology (EPFL) reported success in getting rats with severed spinal cords to walk again. They did so by suspending the animals in a harness, then using implants to electrically stimulate neurons in their lower spinal cord. Although this ultimately resulted in the rats being able to run on their previously-paralyzed hind legs, the technology still wasn't practical for long-term use in humans. Thanks to new research conducted at EPFL, however, that may no longer be the case. Read More
Though printing items like chocolate and pizza might be satisfying enough for some, 3D printing still holds a lot of unfulfilled potential. Talk abounds of disrupting manufacturing, changing the face of construction and even building metal components in space. While it is hard not to get a little bit excited by these potentially world-changing advances, there is one domain where 3D printing is already having a real-life impact. Its capacity to produce customized implants and medical devices tailored specifically to a patient's anatomy has seen it open up all kinds of possibilities in the field of medicine, with the year 2014 having turned up one world-first surgery after another. Let's cast our eye over some of the significant, life-changing procedures to emerge in the past year made possible by 3D printing technology. Read More
