...ing a hysteroscope, a tiny, fiberoptic camera. The metal device encapsulates and holds in place white polyester fibers able to cause scarring and thus block the fallopian tubes within 12 weeks, preventing the possibility of future pregnancy. This method requires minimal sedation and no surgical incision, a...Rice engineers demo first T-ray endoscope
... cables aren't good guides for T-waves because the metal sheath absorbs T-wave energy very quickly, and fiber optics don't transmit T-waves. By blending some aspects of both these technologies, Mittleman's team devised a system to guide T-waves in and out of a confined space. This could prove useful for se...Some herbal medicine products contain potentially toxic amounts of heavy metals
