Publication number: 20240361517Abstract: A terminated hollow-core optical fiber includes a capillary, a hollow-core optical fiber including a structured cladding, and an endcap. A first end of the hollow-core optical fiber terminates inside the capillary a non-zero distance away from a first end face of the capillary. The hollow-core optical fiber is adhered to the capillary at a second end face of the capillary where the hollow-core optical fiber extends out of the capillary. The endcap is fused to the first end face of the capillary. The endcap has a larger diameter than the first end of the hollow-core optical fiber. This termination scheme does not require fusing the hollow-core fiber itself to the endcap or any other part. Therefore, this termination scheme is applicable to hollow-core fibers with a structured cladding that cannot tolerate the temperatures associated with fusing the hollow-core fiber to another part.Type: ApplicationFiled: July 11, 2024Publication date: October 31, 2024Applicant: Optoskand ABInventors: Stuart CAMPBELL, Rasmus KIHLBERG, Mats BLOMQVIST

Patent number: 11407969Abstract: The present invention relates in part to devices, systems, and methods for the production and characterization of engineered tissue constructs. The devices and methods generate decellularized tissue constructs that can be recellularized using donor cells for high-throughput studies of organ physiology, and/or organ pathology. The devices and methods can be used with the systems to mechanically and electrically stimulate the engineered tissue constructs under culture or physiological conditions to detect and assess the presence and degree of any organ pathologies.Type: GrantFiled: January 30, 2018Date of Patent: August 9, 2022Assignee: Yale UniversityInventors: Stuart Campbell, Jonas Schwan, Andrea Kwaczala, Thomas Ryan, Daniel Jacoby, Yibing Qyang, Lorenzo Sewanan, Ronald Ng, Jeffery Alexander Clark
