Pryfiber is developing a flexible micro-endoscope using a single multimode optical fiber.

Endoscopy is widely used for diagnostic and treatment purposes but is a complex procedure. Current endoscopes are too thick and/or inflexible to enter very small spaces like joints or winding lumina such as cardiac arteries and blood vessels in the brain.

Pryfiber are developing a micro-endoscope using only a single optical fibre, less than 0.3mm in diameter – but equipment that small can’t capture a visible image, so on it’s own it would not be much use.

Pryfiber’s innovation is an AI algorithm which uses deep learning to reorganise the light that travels through the micro-endoscope, recreating accurate and useful images in real time.

Clinicians could then use Pryfiber’s ultrathin endoscopes to see into the most difficult to reach places – such as joints or blood vessels in the brain – capturing high-definition images for diagnostics and treatment that have previously been impossible to obtain.

Pryfiber aim to revolutionise diagnostic and interventional endoscopy by becoming the primary enabler of all precision procedures.
