Abstract: An embodiment of a peritoneal dialysis system includes a peritoneal dialysis hardware unit having a housing with a first opening, a door coupled to the housing and having a second opening, and a solid pump piston having a solid piston shaft attached to or integrally formed with a solid piston head. The system also includes a stepper motor operable to cause the solid pump piston to translate; a disposable pumping unit having a first and a second opposing surface, and a fluid pump receptacle extending from the first and second surface to fit within the second opening. The hardware unit and pumping unit are structured and arranged to allow the pumping unit to be placed into the hardware unit such that the fluid pump receptacle is aligned with the first opening, the second opening, and the solid piston head when the door is closed against the housing.

Abstract: A catheter includes a braid assembly having a dual-laminate coating. The braid assembly includes a plurality of braid members interwoven to provide for interstices between the braid members, each braid member having an electrically conductive element, a flexible non-electrically-conductive polymer coating that insulates the electrically conductive element and a thermoplastic bonding adhesive coating. The braid assembly is formed between an inner polymer layer and an outer polymer layer. One or more of the braid members may be coupled to an energy delivery element.

Abstract: A maximum settable dose feature is disclosed that is set by a user or health care professional one time that prevents future injections from exceeding the desired maximum dose. The feature includes a locking band initially in an unlocked configuration, which transforms to a locked configuration when activated after setting a desired maximum dose. The feature can include a trigger mechanism to transform the locking band to the locked configuration.
