CARLSBAD, Calif., March 17 -- Clinical studies are underway for a new device that researchers hope will enable some patients with cardiovascular disease to bypass heart-bypass surgery. Fifteen hospitals are participating in a study that uses fiber optic and radio frequency technology to facilitate a small opening in arteries completely blocked by plaque and fatty deposits that can build up and block circulation. IntraLuminal Therapeutics Inc. of Carlsbad, developed the device, which uses optical coherence reflectometry to analyze reflected near-infrared light transmitted from an angioplasty...Read full articleRelated content from Photonics MediaArticlesPhotonic Chip Drives Scalable Data TransferSystems that run artificial intelligence programs, such as large language models, face a “bandwidth bottleneck” that can limit the amount of data they transfer between nodes.
