US Classification:

210232, 210445, 210446, 210483

Abstract:

Flow-through systems for processing biological fluid are disclosed. The flow-through systems include a removal device in the flow path for removing unwanted compounds and agents. The removal device includes a removal media contained within a housing made of two separate portions sealed together. The housing is maintained in a substantially vertical disposition, thereby ensuring substantially uniform and complete exposure of the fluid to the media.

International Classification:

B32B 3116

US Classification:

156 731

Abstract:

An ultrasonic welding horn is provided that has an insert connected to the body of the horn proximal to the welding edge, the insert being dampened from the ultrasonic operating frequency by attaching it to the horn body at a nodal point that has little or no vibration during the operational vibrational mode of the horn. During a welding operation, the insert is positioned to secure living cell tissue that is between two plastic layers, preventing undesirable vibration of the cell tissue. The welding edge, which extends around the periphery of the insert, contacts the plastic layers around the cell tissue, welding a seal between the layers.

International Classification:

A61F 202

US Classification:

623 11

Abstract:

A method for implanting cells into a host tissue is provided. The method comprises the steps of: creating an implant assembly for holding cells including wall means for forming a porous boundary between the host tissue and the implanted cells in the device, the pore size of the boundary being sufficient to isolate the implanted cells from the immune response; implanting the assembly without the cells into a host tissue; and accessing an interior of the assembly to add the cells thereto.

International Classification:

F16L 1112

US Classification:

285 49

Abstract:

A vibration decoupling exhaust connector is provided having a flange for mounting the connector to a flange or housing surface of an exhaust system component, such as an exhaust manifold of an internal combustion engine. A liner tube is resiliently supported in the flange, by a vibration damping resilient metal mesh ring. A bellows is sealingly connected to the liner tube and the flange, in order to provide flexible sealing of the connector, for substantially precluding escape of exhaust gases from the joint when the connector is in place.

International Classification:

A61F 202

US Classification:

623 11

Abstract:

Improved Implant assemblies and methodologies provide immuno-protection for implanted allografts, xenografts, and isografts. The assemblies and methodologies establish an improved chamber for holding the implanted cells. The chambers include first and second wall elements and an intermediate sealing element. The first and second wall elements overlie an open area in the sealing member to form a chamber for holding cells for implantation. A sealed region is created between the wall elements and the sealing element body to close the chamber. In one arrangement, the sealed region is created by means of a sonic weld made while the implanted cells are present in the chamber. In another arrangement, the sealed region is created by means of applying an external force to compress the peripheral edges of the wall elements and the sealing element together while the implanted cells are present in the chamber.

International Classification:

H04M 164

US Classification:

379 67

Abstract:

Systems and methods for recording and delivering personalized audio messages are provided. The system includes a central facility computer system (CF), a store front programming system (SFS), and a portable playback device (PPD). When a customer desires to send a personalized message to another person, the customer communicates via a telecommunications channel with the CF. Under control of a CF processor, a outgoing message module of the CF provides instructions to the customer, who enters required information and provides the personalized audio message. The personalized audio message is digitized by a CF voice digitizer and transmitted from the CF via a data interface to the SFS. The SFS receives the digitized personalized audio message data from the CF and uses its playback device programmer to program data representing the audio message onto the PPD. The PPD is an audio chip having a nonvolatile memory, an external switch, a battery and a speaker. When the switch is pressed, the data representing the audio message stored in the memory is sent to the speaker (via a D/A converter where the data is digital) where a facsimile of the original audio message is heard.

Abstract:

A method and apparatus for implanting cells in a host is provided. In an embodiment, an implant assembly for a host tissue is provided comprising wall means defining a chamber for holding cells for implantation, the wall means including means for foxing a porous boundary between the host tissue and the implanted cells in the chamber, the pore size of the boundary being sufficient to isolate the implanted cells from the immune response of the host tissue, and port means for providing selective access to the chamber.
