Abstract: Display devices include waveguides with in-coupling optical elements that mitigate re-bounce of in-coupled light to improve in-coupling efficiency and/or uniformity. A waveguide receives light from a light source and includes an in-coupling optical element that in-couples the received light to propagate by total internal reflection within the waveguide. The in-coupled light may undergo re-bounce, in which the light reflects off a waveguide surface and, after the reflection, strikes the in-coupling optical element. Upon striking the in-coupling optical element, the light may be partially absorbed and/or out-coupled by the optical element, thereby reducing the amount of in-coupled light propagating through the waveguide.

Abstract: Described herein are systems, devices and methods that enable dynamic modification of the physicochemical properties of a hydrogel during its in vivo formation and delivery by a catheter. In some example embodiments, an extended endoluminal hydrogel delivery device is employed for delivering a hydrogel within given body cavity, such as within the lumen of a blood vessels. In some example embodiments, a hydrogel precursor, as a non-viscous liquid, is injected through an intravascular catheter and crosslinking of the hydrogel precursor is initiated within a distal region of the catheter. The crosslinking process is controlled, by a control means associated with a distal region of the catheter, to control or modify one or more properties of the hydrogel. The properties may be controlled such that a hydrogel is suitable to embolize the specific target or deliver drugs or other materials beneficial to the site.
