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.

Neovaginal and vaginal health devices

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.

Gravity independent medical drainage systems

An optical pattern-driven light induced dielectrophoresis (DEP) apparatus and separation methods are described which provide for the manipulation of particles or cells and selection based on traits correlated with the DEP response. Embodiments of the apparatus use DEP electric field patterns in combination with microfluidic laminar flows to measure response, separate, segregate and extract particles from heterogeneous mixtures according to the relative response of the particles to one or more DEP fields without damaging living cells. The preferred OET-DEP devices generally comprise a planar liquid-filled structure having one or more portions which are photoconductive to convert incoming light to a localized virtual electrode with a DEP electric field gradient of selected intensity along with input and a plurality of output fluidic channels. The light patterns are dynamically generated to provide a number of manipulation structures that can manipulate single particles and cells or groups of particles/cells. The methods are particularly suited for selecting and extracting the best sperm and embryo candidates based on fitness for use with existing artificial reproduction procedures and excluding defective or non-viable gametes.

Methods and devices for sorting cells and other biological particulates

Provided are methods, systems, devices, and computer programs enabling the measurement of various objects using imaging. The inventions are adaptable to mobile devices such as smartphones, allowing a range of unique measurements to be conveniently made, including length, area, distance, velocity, and height. The methods, systems, devices, and computer programs include the novel application of image-based measurement in medical, research, and other contexts.

Image-based measurement tools

There is provided, inter alia, a catheter incorporating one or more of a burstable element, a safety balloon, a marking to indication proper insertion amount for the catheter, a slit valve, and a non-fragmenting retention balloon

Active and passive wound drainage systems and method are provided. A drainage device includes an input passage for receiving the fluid from a site on or within the patient's body, a container for holding the fluid, and a reversible valve disposed between the input passage and the container. The reversible valve in an original configuration provides unidirectional fluid flow from the input passage toward the container, and in a reversed configuration provides fluid flow from the container toward the input passage.

Drainage devices and methods

The present invention relates generally to a method and devices for the detection of target objects, such as landmines, using the odor characteristics which may be associated with the target objects as a way of detecting their presence. The invention includes devices used to carry out a method of training live animals, such as rats, to seek out the target objects in the field, or to localize, unearth, and mark the location thereof.

Method and apparatus for detecting target objects

The present invention relates generally to a method and related devices for the deactivation of landmines. More particularly, the present invention includes several devices used to carry out a method of training live animals, such as rats, to seek out and destroy active landmines in the field, or to localize, unearth, and mark the location of active mines, thereby reducing the danger of their later removal by valuable sniffing mine clearing animals, technology, and mine clearing personnel, making a landmine clearance effort more effective and efficient.
