  • Patent number: 10702689
    Abstract: An intravenous delivery system may have a liquid source containing a liquid, tubing, and a vent cap. The tubing may be connected to the liquid source and the vent cap to convey liquid from the liquid source to the vent cap. The vent cap may have a vent that is substantially impermeable to the liquid and permeable to air, and therefore releases air from the liquid from the vent cap. The vent cap may also have a chamber in communication with the vent. The chamber may have a volume selected to enable the chamber to receive a quantity of liquid from the tubing in which the air, if entrained in the liquid, is likely to reside after the tubing has been primed with the liquid.

  • Patent number: 10668254
    Abstract: A coaxial stabilizing and sealing catheter provides increased support to a guide catheter that is seated in an ostium of a branch artery by extending through and out of a distal end of the guide catheter and anchoring in position within the vessel that is being treated. The stabilizing and sealing catheter includes, as part of a relatively flexible distal section, a balloon that locks the distal end of the stabilizing and sealing catheter in place to provide support to the therapeutic devices that are introduced and further seals the artery to prevent blood from entering the artery. A sealing cuff at a proximal end of the stabilizing and sealing catheter provides a seal between the exterior of the stabilizing and sealing catheter and the interior of the guide catheter. In addition, a fixing mechanism it utilized to lock the guide catheter in place to exchange therapeutic devices.

  • Patent number: 10632261
    Abstract: A self-admixing disposable hypodermic needle (admixing needle) includes a reservoir containing an additive, such as a buffering agent, to facilitate homogeneous mixing of the additive with an injection fluid, such as Lidocaine, contained in a cartridge held within a mechanically conjoined syringe. The admixing needle establishes a fluid communication pathway for hypodermically delivering the injection mixture to a patient preceding a potentially painful dental or medical procedure. Prior to removal, a delivery needle cap is pushed toward the syringe to dispense the additive into the cartridge. The delivery needle is then placed within the patient's tissues and the syringe is operated to force the injection mixture from the cartridge. Mixing surfaces on the male body (reservoir plunger) and the female body (reservoir) and other mechanical features homogeneously combine the injection fluid with the additive as the injection mixture travels through the admixing needle during the hypodermic injection.
