Abstract: A urinary catheter has a body and an outer layer surrounding at least a portion of the body. The structure of the body is varied and non-uniform so as to impart a varying flexibility along the length of the catheter. The frame may be injection molded, while the outer layer may be extruded. The frame may also, or alternatively, have selected regions or portions that include planar or spiral cuts or a coiled filament or corrugations or a multifilament braid or weave or mesh to impart a desired flexibility profile. The flexibility profile of a male urinary catheter may include alternating rigid and flexible regions, with proximal and distal rigid regions being configured to be positioned within the bladder and penis, with two flexible regions separated by a rigid region positioned between the penis and bladder when the catheter is deployed within a male urethra.

Abstract: A glow stick includes a housing, a lighting assembly mounted within the housing, having at least two light sources, at least one power source, at least one switch and circuitry for controlling the at least two light sources. An elongated body is mounted to the housing and is formed from a material that is transparent or translucent to light transmission. One of the light sources is mounted within the housing to provide a flashlight that is mounted to the housing at an angle between 0 and 180 degrees and the other light source is directed into the elongated body to illuminate the elongated body so that light is visible therefrom. The light source for the flashlight is switchable between a constant on and a constant off state and the light source illuminating the body is switchable among a constant on state, a constant off state and an intermittent state. The flashlight light source and the body light source are operable independently of one another.
