Researchers at the University of California, Riverside have developed a transparent prosthetic implant that can replace a piece of skull. As MedGadget reports, the transparent piece is made of a biocompatible ceramic used in previous device implants. They see their invention as having both diagnostic and therapeutic use. For example, it could allow doctors to monitor disease sites. But a transparent "brain window" also allows laser light that can't otherwise pass through the skull to have a practical use. The article notes that the invention could enable surgeons to ablate anything that needs removal, bypassing problems caused by cranium obstruction. Story
