  • Patent number: 10857345
    Abstract: A medical connector assembly for establishing a fluid connection between a first medical device and a second medical device includes a multi-use connector and a plurality of single-use connectors connected in series. The multi-use connector has a proximal end opposite a distal end along a longitudinal length thereof. The plurality of single-use connectors each have a proximal end opposite a distal end along a longitudinal length thereof. The distal end of the multi-use connector is releasably connected to the proximal end of a first of the serially-connected single-use connectors. When a second of the serially-connected single-use connectors is disconnected from the first single-use connector, the first single-use connector remains connected to the multi-use medical connector as a sterility retaining cover.

  • Patent number: 9764081
    Abstract: A fluid path set including a multi-patient use section adapted for connection with a pump device and a source of injection fluid, and a per-patient use section adapted for removable fluid communication with the multi-patient use section.

  • Patent number: 9561344
    Abstract: A catheter including an outer conduit and an inner conduit positioned within the outer conduit, the inner conduit having a smaller diameter that that of the outer conduit. A volume between the outer conduit and the inner conduit define a first lumen which may deliver a first fluid to a patient, and an inside diameter of the inner conduit defines a second lumen which may deliver a second fluid to the patient such that the fluid flow of the first fluid and the second fluid exiting the catheter has a flow profile where the first fluid surrounds the second fluid and the second fluid is prevented from contact with inner walls of a blood vessel of the patient in a vicinity of a tip of the catheter.
