Abstract: One aspect is an illumination assembly including: a first light emitting element; a first counterweight; and at least one of a nock or a connector configured to attach the illumination assembly to a nock, such that the first light emitting element and the first counterweight are positioned symmetrically from each other relative to the nock on opposite sides of the nock. Preferably the first light emitting element is substantially the same mass as the first counterweight. The illumination assembly can include a shaft of an arrow or bolt and/or include an adapter configured to attach to a shaft of an arrow or bolt, such that the first light emitting element and the first counterweight are collinear on a virtual line substantially perpendicular to the central axis of the arrow or bolt, and such that the first light emitting element is positioned off of the central axis of the arrow or bolt and configured to emit light in a rearward direction offset from the central axis of the arrow or bolt.

Abstract: An incontinence treatment device and method of treating urinary incontinence in a person includes fabricating an artificial urethra to have a flow diameter formed inside of a circumferential wall and a closure device attached directly to a portion of an outer surface of the circumferential wall of the artificial urethra. The artificial urethra is sized to be spliced to a natural urethra for alignment of the flow diameter of the artificial urethra with a lumen of the natural urethra. A pump is provided for moving liquid out of a reservoir and into the closure device to push the outer surface of the circumferential wall into the flow diameter of the artificial urethra, which operates to close the flow diameter of the artificial urethra.

Abstract: An incontinence treatment device includes a section of synthetic urethra and a closure device attached to the section of synthetic urethra. The section of synthetic urethra provides a flow diameter and is configured to be spliced into a natural urethra such that the flow diameter is aligned with a lumen of the natural urethra for passage of urine. The closure device is attached to the section of synthetic urethra and operable to coapt the flow diameter to allow a user to impede the passage of urine and be continent.

Abstract: An incontinence treatment device includes a synthetic urethra and a cuff separate from the synthetic urethra. The synthetic urethra provides a flow diameter that is configured to be spliced into a natural urethra such that the flow diameter is aligned with a lumen of the natural urethra for passage of urine. A closure device includes a pump communicating between a reservoir and the cuff. The cuff is attachable around an outer circumference of the synthetic urethra. The pump is operable to move a liquid from the reservoir to inflate the cuff, the inflated cuff adapted to circumferentially compress and constrict the flow diameter of the synthetic urethra.
