Abstract: The disclosure concerns systems for use in anastomosis of tubular biological organs within the body, particularly small tubular organs, such as blood vessels, bile duct, lymph duct, nerve ducts, epididymis, etc. The anastomosis system comprises a coupling device with a body, typically within a housing, a coupling assembly linked to the body, a plurality of suturing units within the coupling assembly, and an actuator arrangement formed within the coupling device.

Abstract: Disclosed is a wearable optical devices for a human subject, comprising: a transparent lens; a wearable frame configured to maintain the lens in front of an eye of a human subject; a transparent pixelated active optical element where the pixels of the active optical element have an optical property with a changeable value; an eye tracker; and a controller configured to set a value for an optical property of the pixels of the active optical element so as to create an image mask through which at least some of the light reaching the feye passes through, thereby modifying the image formed on the retina of the first eye.
