Abstract: A laser strikes and aseptically heats or sterilizes the end of two flexible tube ends for connection. Tube holders are pushed toward each other to bring the tube ends into contact. A weld detector checks the characteristics of the weld. A laser optics assembly may be used to change the direction of the laser and focus the laser at the tube ends. In addition, a crimping device is used to compress a single flexible tube for disconnection. The laser strikes the compressed area. The crimping device continues to pinch the area and forms a seal in the tube. The tube is separated into two tube segments, each segment has a sealed end.

Abstract: The present invention provides a connector device or reconstitution device (10) for placing a first container (12), such as a liquid container (e.g. flexible container or syringe), in fluid communication with a second container (14), such as a drug vial. The connector device (10) has a first sleeve (32) having a first end (36) and a second end (38). The first sleeve (32) has at the first end (36), a first attaching member (30) adapted to attach to the liquid container (12). The connector device (10) also has a second sleeve (34) having a first end (48) and a second end (50). A second attaching member (28) is attached on the second end (50) of the second sleeve (34) and is adapted to attach to the second container (14). The second attaching member (28) has a sealing member (84). A piercing member (76) projects within the sleeves (32,34) for providing a fluid flow path from the first container (12) to the second container (14).
Abstract: A method, system and apparatus for performing peritoneal dialysis are provided. To this end, in part, a dialysis system is provided. The dialysis system includes a display device and a web browser and web server embedded in the dialysis system. The browser and the server operate with the display device to display a number of dialysis therapy set-up procedure screens that require operator input, and to display a number of dialysis treatment screens that graphically illustrate the progress of at least one step in the dialysis therapy in at least substantially real time.

Abstract: A number of improvements relating to methods and apparatuses for kidney dialysis are disclosed. These include a method providing an apparatus for dialyzing to a consumer, with the apparatus including a controller for controlling a dialysate parameter, a delivery system for delivering the dialysate to a dialysate compartment of a dialyzer, and a user/machine interface having a touch screen to display an indicium corresponding to a parameter pertinent to operation of the apparatus for use in dialysis and to enable a user though touching the indicium to effect a change in the parameter. The method also includes providing supplies that are useable with the apparatus to the consumer.

Abstract: A catheter suitable for use in performing peritoneal dialysis. The catheter is a dual lumen catheter which allows for continuous flow peritoneal dialysis. Dialysate flows through the catheter into the patient via one lumen and simultaneously flows through the catheter out of the patient via the second lumen. The dual lumen dialysis catheter has a flexible tube which has an implantable portion extending from an external patient portion. Both of the lumens have openings in the external patient portion for connecting to a supply and drain of dialysate, respectively. The implantable portion has a preformed curved segment which has an outlet for the first lumen to flow dialysate into the patient's peritoneal cavity. The implantable portion has an opening for the second lumen at the distal end to flow dialysate out of the peritoneal cavity and removal from the patient.

Abstract: A method and system for handling a packet data service wherein, proceeding from the handling of a packet data service by a service network node of a packet data network to which communication terminal equipment is connected for the transmission of packet data, it occurs that a data switching function of an interworking of the packet data service with network functions of an intelligent network is interconnected to the service network node, and the setting of at least one threshold for the packet data transmission is undertaken by the service control function for monitoring a packet data stream in the packet data network wherein the service control function communicates this threshold to the service switching function.
Abstract: A system and method are provided for monitoring and/or controlling a sterilization system. Briefly described, in architecture, the system can be implemented as follows. A current transformer is operatively associated with a source of power for a radiation source. A power meter is operatively associated with the source of power. The power meter is also operatively associated with the current transformer. The power meter is designed to monitor the source of power to confirm the radiation source provides a desired dosage.
Abstract: A number of improvements relating to methods and apparatuses for kidney dialysis are disclosed.
