Researchers tout biomaterials that can be ‘fine-tuned’ for medtech

Researchers in the UK and U.S. are touting a new thermoplastic biomaterial capable of “fine-tuning” for use in soft tissue repair or bioelectronics.

According to a news release, the material, which is a type of polyester, has been developed by a team at the University of Birmingham (UK) and Duke University (U.S.) for use in repairing soft tissue or flexible bioelectronics by fine-tuning it to enable the rate at which it degrades in the body and allow its mechanical properties to be controlled independently.

The team has shown how the addition of succinic acid, which is naturally found within the body, can be used to control the degradation rate, allowing the polyester biomaterial to degrade gradually over a period of four months as healthy tissues grow in and eventually replace the implant. Tests in rats confirmed the material’s biocompatibility and safety, the researchers said.

Researchers determined that, by varying the amounts of suc…

Researchers develop 3D VR blood flow to improve cardiovascular care

Duke University engineers are developing a fluid dynamics simulator that models blood flow in the full human arterial system at a subcellular resolution.

The biomedical engineers hope the simulator will give doctors guidance in treatment plans by simulating specific vasculatures of patients to predict how stent placements, conduit insertions and other geometric alterations to blood flow can affect surgical outcomes.

Duke University researchers developed the tool, called Harvey, by exploring various interfaces ranging from standard desktop displays to immersive virtual reality experiences. They found that futuristic interfaces could be the key to widespread adoption of the technology.

“Harvey currently requires knowledge of C coding and command-line interfaces, which really limits who can use the program,” Amanda Randles, assistant professor of biomedical sc…
