Abstract: The scope of the invention encompasses novel, multifunctional tools for maintaining the neovagina. The tools comprise novel dilator shapes that conform the anatomical pathway of the neovagina. The tools may further include a douching function for the effective and thorough washing of the neovagina, which is not achieved with standard douching devices. The tools may also comprise a measurement function for medical evaluation of the neovagina and to aid in proper dilation. Also presented herein are novel devices for delivery of agents to the natal vagina, including insemination devices.

Abstract: Provided herein are medical drainage systems comprising structures to prevent blockages within drainage tubing, especially medical drainage tubing, for example caused by debris or airlocks. The novel systems of the invention employ, in some embodiments, elements of the Archimedian screw. The Archimedian screw elements comprise a rotating conveyer present in the tubing which promotes continuous flow of material through the tubing and prevents the formation of dependent loops and other blockages. The systems of the invention may be employed in diverse contexts, including urinary catheter drainage systems and thoracostamy systems. The systems of the invention, being gravity independent, may also be employed for the drainage or a movement of materials in space and other low gravity environments.
