  • Patent number: 11129934
    Abstract: A pressure jacket for use with a fluid injector includes a barrel having a distal end, a proximal end, and a sidewall extending between the distal end and the proximal end along a longitudinal axis. The pressure jacket includes at least one engagement member protruding from a terminal portion of the proximal end of the barrel in a proximal direction along the longitudinal axis. The at least one engagement member tapers axially in a direction from the distal end toward the proximal end of the barrel. The at least one engagement member engages with a locking mechanism on the fluid injector to releasably lock the pressure jacket with the fluid injector. A taper of the at least one engagement member rotationally guides the barrel into self-alignment with the locking mechanism and axially ejects the barrel upon rotation of the barrel about the longitudinal axis.

  • 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: 10792418
    Abstract: A pressure jacket includes a barrel having a proximal end, a distal end, and a sidewall extending substantially circumferentially between the proximal end and the distal end along a longitudinal axis. The pressure jacket also includes at least one retaining member having at least one first lug protruding radially outward relative to an outer surface of the sidewall. The at least one first lug has at least one third surface tapered axially relative to the longitudinal axis of the barrel in a proximal direction. The at least one first lug is configured for engagement with a locking mechanism associated with a port on a fluid injector to releasably lock the pressure jacket with the fluid injector. At least a portion of the at least one third surface axially ejects the pressure jacket upon rotation of the pressure jacket about the longitudinal axis.

  • Publication number: 20200222634
    Abstract: A syringe for a fluid delivery system includes a pressure jacket having a distal end, a proximal end, and a throughbore therebetween. The syringe further includes a rolling diaphragm having a proximal end with an end wall for engaging a plunger, a distal end received within the throughbore of the pressure jacket. The distal end of the rolling diaphragm has a nozzle and a sidewall extending between the proximal end and the distal end of the rolling diaphragm along a longitudinal axis. At least a portion of one of the sidewall and the end wall has non-uniform thickness. At least a portion of the sidewall is flexible and rolls upon itself when acted upon by the plunger such that an outer surface of the sidewall at a folding region is folded in a radially inward direction as the plunger is advanced from the proximal end to the distal end of the rolling diaphragm.

  • Patent number: 10512720
    Abstract: A syringe includes a barrel having a distal end, a proximal end, and a sidewall extending therebetween along a longitudinal axis. At least one engagement member protrudes from a terminal portion of the sidewall in a proximal direction along the longitudinal axis. The at least one engagement member tapers axially in a direction from the distal end toward the proximal end. The at least one engagement member is configured for engagement with a locking mechanism of a fluid injector to releasably lock the syringe with the fluid injector. A taper of the at least one engagement member is configured to rotationally guide the syringe into alignment with the locking mechanism and axially eject the syringe upon rotation of the syringe. The locking mechanism operatively engages the at least one engagement member regardless of an orientation of the syringe about the longitudinal axis relative to the injector.

  • Patent number: 10478558
    Abstract: Systems and methods for intelligently delivering fluid to a targeted tissue are described. The systems and methods may include directing a pump to distribute fluid to a targeted tissue and receiving one or more signals from an intracorporeal sensing system, where the one or more signals correspond to one or more sensed feedback parameters at the targeted tissue. The systems and methods may also include determining whether the one or more sensed feedback parameters are within an acceptable range. If the one or more sensed feedback parameters are not within the acceptable range, the systems and methods may include determining an adjusted velocity for the plunger necessary to adjust the pressure of the fluid in the pump so that the one or more sensed feedback parameters move within the acceptable range and directing the pump to distribute the fluid at the adjusted velocity.
