Abstract: A chamber, system, and method for separating a selected component from a fluid are provided. The chamber is capable of rotating about the central axis of a centrifuge device and includes a radially-extending duct having an optimized variable cross-sectional area that decreases in relation to the outward radial distance from the central axis of the centrifuge. The optimized geometrical design of the duct provides that a centrifugal force exerted on the selected component caused by the rotation of the chamber substantially balances the drag force exerted on the selected component by the fluid as the selected component flows through the duct. Thus, the duct allows the selected component to be dispersed in equilibrium along the radial length of the duct such that the selected component may be effectively suspended with the duct and/or separated from the fluid using elutriation or other methods.

Abstract: The present invention is directed to compositions and apparatus to be used in methods of implantation of embryos for in vitro fertilization. The methods include insertion of embryos that have attached adhesives. Such methods, compositions and apparatus can be used with any mammals, including humans, farm animals and exotic or endangered animals.
