Abstract:
A clamp device for a barb member having a barbed region for disposing within an end of a flexible tube having an outer surface. The clamp device includes a flexible member including a body having a plurality of finger members compressible between a first resting position and a second clamping position; at least one of the flexible finger members having a radially inwardly extending tooth; the body having a through bore and an outer surface comprising threads; the flexible member being slidable over the barbed region and the outer surface of the flexible tube; a compression member having a body having a through bore and an inner surface including threads; the compression member being slidable over the flexible member; wherein upon threadingly engaging the compression member with the flexible member, the compression member compresses the finger member against the barb member.
Abstract:
A disposable container such as a deformable bag for a fluid having one or more inlets and one or more outlets and an impeller assembly within the container to cause mixing dispersing homogenizing and/or circulation of one or more ingredients contained or added to the container. The region within the container that can contain liquid is funnel shaped which allows very low fluid level mixing dispensing while mixing and a reduction or elimination of vortex formation.

Abstract:
The present invention is a device for fluid movement and method of making the same. The device has a core element comprised of a preformed barbed fitting having two or more barbed extensions. Each extension has a central bore connected to the central bores of the other extensions so as to provide fluid communications between them. A tube having a central bore is fitted over the barb of each extension. A molded housing is formed over the fitting and tubes to form the device.
Abstract:
Containers for separating microcarriers from a cell culture fluid that offer a greater efficiency of filtration of cell culture fluids containing microcarriers relative to systems described in the art. The container may include a first compartment that may include a sterile collapsible bag, an inlet port providing a fluid path into the first compartment and an outlet port providing a fluid path exiting the first compartment; and a second compartment fluidly connected with the inlet port of the first compartment and including a plurality of independent or discrete microcarrier receiving regions defined by boundary walls which are partially or fully porous and having a porosity sufficient to retain the microcarriers inside the second compartment, while allowing the cell culture fluid to pass through the second compartment into the outlet port of the first compartment, where the cell culture fluid can be collected.

Abstract:
A disposable flow path having a manifold system that provides pressure resistance for the disposable device. The disposable device is comprised of a first rigid plastic sheet and a second rigid plastic sheet. Each sheet has two major surfaces and a thickness between them. At least one sheet surface has flow channels formed in it. The flow channels extend away from a first major surface and beyond the normal plane of a second major surface of the sheet. The sheets are liquid tightly sealed to each other at their adjoining first major surfaces. When each sheet contains a flow channel, the flow channels are aligned and in register with each other. One or more fittings can be secured in the flow channel(s) at an edge of the two liquid tightly sealed sheets. Alternatively, tubing is placed in the channels before the sheets are secured to one another.
Abstract:
Un dispositivo de transferencia (2) para manejar fluidos de una manera estéril, que comprende: un cuerpo (4) que tiene un ánima (10) formada a través de por lo menos una parte de su interior, el cuerpo (4) tiene un primer extremo (6) conectable a un componente aguas arriba (54; 72); una abertura (62) situada aguas abajo del primer extremo (6), la abertura se puede conectar a un componente aguas abajo (56; 64; 210); un émbolo (18; 70; 98; 108) contenido dentro del ánima, el émbolo tiene un primer extremo y es movible dentro del ánima (10), por el movimiento de una leva (32) en una ranura (36) de leva que define un movimiento axial y una rotación y que limita la longitud de desplazamiento del émbolo en el ánima, entre una posición cerrada que corresponde a una posición cerrada del dispositivo en la que el primer extremo (6) del cuerpo (4) está cerrado herméticamente respecto la abertura (62) mediante un primer cierre hermético (38) y una posición abierta que corresponde a una posición abierta del dispositivo en el que el primer extremo (6) del cuerpo y la abertura se conectan con transferencia de fluidos, en donde, cuando el émbolo buzo (18; 70; 98; 108) está en la posición cerrada, el primer extremo del émbolo (18; 70; 98; 108) combinado con el primer extremo (6) del cuerpo (4) forman una superficie (46; 104) configurada para ser esterilizada con vapor de agua y una barrera estéril entre el ambiente y por lo menos una parte del interior del cuerpo (4) y el émbolo (18; 70; 98; 108); un recorrido (27; 74) de fluido que forma una conexión de fluidos a través del dispositivo entre el primer extremo (6) y la abertura (62) cuando el dispositivo está en la posición abierta; y un cierre hermético adicional que comprende dos cierres herméticos (38) o un cierre hermético lineal o de prensaestopas (90) dispuesto a lo largo del émbolo (18; 70; 98; 108) para formar un cierre hermético a líquidos entre diversas partes del émbolo (18; 70; 98; 108) y el ánima (10) cuando el émbolo (18; 70; 98; 108) está en la posición abierta para permitir la transferencia de fluido a través del recorrido de fluido al tiempo que se mantiene el estado estéril del fluido que se está transfiriendo siempre y cuando se mantenga una conexión estéril con el componente aguas arriba y el componente aguas abajo.
