Abstract: A method of extracting a catheter assembly with an extracting device. The catheter includes a tissue ingrowth cuff that is grown into a subcutaneous location. The extracting device includes a handle and a head having an external gripping surface which is sized for inserting into a lumen of the catheter assembly for gripping an internal surface of the catheter assembly within the tissue ingrowth cuff and dislodging the cuff from surrounding tissue.

Abstract: A flow regulating assembly and components are provided for a catheter system. The assembly provides a regulated flow of medical fluid with an intermittent operator-controlled large-volume flushing flow. The assembly includes a flow-occluding piston reciprocal within a housing to move from the regulated flow position to a position completely out of the path of fluid flow from the inlet to the outlet. Actuation of the piston is from the exterior of the housing, and adjustment of the regulated flow volume is also effected from the housing exterior. The assembly components may be sterilized and fitted together in a clean room without welding or gluing being necessary.

Abstract: A flushing device for placement in a slow infusion line of liquid to a human or animal body through a catheter, cannula or similar item that provides a flushing or cleaning by-pass route merely by, and only during, finger pressure applied to the flushing actuator.
