  • Publication number: 20230404666
    Abstract: A microwave ablation antenna assembly including a coaxial cable terminating in a radiating section, a first tubular member circumscribing the coaxial cable and spaced therefrom to permit fluid flow therebetween, and a second tubular member circumscribing the first tubular member and spaced therefrom to permit fluid flow therebetween. The microwave ablation antenna assembly further includes a hub configured to receive the coaxial cable, first tubular member, and second tubular member, the hub including a fluid inflow chamber and a fluid outflow chamber and an integrated hub divider and hub cap separating the fluid inflow chamber from the fluid outflow chamber and prohibiting fluid flow between the inflow chamber and outflow chamber except via the spacing between the coaxial cable and the first tubular member and between the first tubular member and the second tubular member.

  • Publication number: 20230248958
    Abstract: A multi-tubing intravenous (IV) extension set may include an outlet tubing fluidly coupled to a primary multi-tubing connector at one end and fluidly coupled to a vascular device at an opposite end, and a primary inlet tubing having a proximal end with an adapter for connection to a syringe containing a priming or a medicinal fluid, and a distal end coupled to the primary multi-tubing connector. The IV extension set may further include at least one secondary inlet tubing with a proximal end having an adapter for receiving a medicinal fluid and a distal end selectively fluidly coupled to the primary multi-tubing connector. A slide clamp may be positioned on the outlet tubing to restrict flow between the proximal and distal ends of the outlet tubing and cause priming fluid flowing into the outlet tubing via the multi-tubing connector to reverse direction into the at least one secondary inlet tubing.

  • Publication number: 20210251688
    Abstract: A microwave ablation device includes a cable assembly, a feedline, and a transmission line. The cable assembly is configured to connect to an energy source. The feedline is in electrical communication with the cable assembly and includes a first temperature sensor. The first temperature sensor is disposed at a first axial location along a length of the feedline and is configured to sense a temperature at the first axial location. The first temperature sensor extends along the length of the feedline. The transmission line extends from the first temperature sensor and is disposed parallel and in contact with an outer conductor of the feedline.

  • Patent number: 9814844
    Abstract: A drug-delivery cannula assembly includes a cannula housing adapted for receiving at least one obturator shaft of an obturator assembly therethrough, one or more cannulae, and a supply line coupled to the cannula housing. The cannula housing is adapted for receiving one or more obturator shafts of an obturator assembly therethrough. The one or more cannulae define a longitudinal axis and a passageway aligned with the longitudinal axis. The one or more cannulae each include a proximal end coupled to the cannula housing. The cannula housing is configured to fluidly-couple the one or more cannulae to a source of a drug delivery supply for supplying drugs via the supply line to the one or more cannulae.
