Abstract: A device with a flexible member configured to take on a curvilinear profile can be used to perform arthroscopic procedures. The device can be used to perform such procedures through two access ports, providing visualization and access to the entire site of the procedure, e.g. hip joint, without switching cannulated access portals or providing additional access portals.

Abstract: An automated blood separation method and apparatus is described that allows for the separation of multiple units of blood simultaneously. The method and apparatus reliably and quickly separates blood into its components. An auto-balancing feature within the apparatus automatically preferably compensates for the changing state of imbalance, thereby eliminating the need for additional balancing steps during the separation process. The apparatus has a rotor into which a plurality of cassettes can be inserted. The cassettes have a number of sections for the containment of the whole blood and for the separated blood components, which are contained in disposable bags. The rotor is placed into a centrifuge assembly, and the blood components are then separated and transferred to the bags in the individual sections of the cassettes. Means for including secondary separation devices such as filters is included.

Abstract: A sealed centrifugal clarifier with a pre-sterilized and disposable container which lines the separation chamber is disclosed. More particularly, the centrifugal clarifier contains a feed port that allows a liquid-solid mixture to be continuously fed into the device wherein the solid is sedimented by rotation of the separation chamber and the clarified liquid is released into an outside receptacle through an effluent port. The throughput rate of the clarifier is adjustable and can be determined as a function of the fill radius of the separation chamber.
