  • Publication number: 20070106205
    Abstract: Apparatuses and methods for providing sterile connection during, for example, dialysis therapy. The present invention provides a connector and a cap therefore that easily and readily attaches to a dialysate container and a catheter inserted into a patient's peritoneal cavity. The connector and the cap enable the dialysate to readily transport between the container and the peritoneal cavity while minimizing the potential of contamination therein due to, for example, handling during use. The connector includes a shell that encloses a cap. The cap houses a slit septum and also includes a sealed disinfectant within an interior receptacle. When the catheter or catheter set attaches to the cap, the seal breaks and the disinfectant spreads over the threads between the catheter set and the cap.

  • Patent number: 6874522
    Abstract: A connector, a container using the connector and a method for establishing fluid communication with a container. The connector may include a first coupling member and a second coupling member. The container may attach to the first coupling member. The first coupling member may have a first passageway with a spike and a membrane located therein. The second coupling member may have a second passageway. The first coupling member may engage the second coupling member and may further pierce the membrane with the spike. The first coupling member may further have a female end of a luer-lock, and the second coupling member may have a male end of a luer-lock. The first coupling member and the second coupling member may be engaged by twisting the male end and the female end of the coupling members to form the connector and establish fluid communication with the container.

  • Publication number: 20040254513
    Abstract: Conductive materials and devices, apparatuses, systems and methods that employ same. The conductive material can include a conductive polymer material that can be utilized to monitor one or a combination of conditions during patient therapy, such as patient access, solution compounding and the like. This can facilitate the safe and effective administration of patient therapy, such as dialysis therapy.
