SIPS device. (A) Full view of the medical-grade gauge 18 needle (inner diameter 0.91Â mm, outer diameter 1.27Â mm) with the integrated optical system. Scale bar: 10Â mm. (B) Magnified view of the needle tip with the micro-camera OCHTA10 and illumination source (three multimode optical fibers connected to a cold white LED) housed in an ultra-thin wall polyimide tubing. These fibers were secured using the polymer OrmoComp. Scale bar: 2Â mm.
