  • Patent number: 11707604
    Abstract: A primer may be used with IV catheter systems. The primer may be positioned along the tubing of an extension set such that the primer divides the IV catheter system into a downstream portion and an upstream portion. The primer may vent air from both the upstream and downstream portions to allow blood to flow up to the primer while also allowing priming solution to flow down to the primer. As a result, the catheter may be inserted into the patient's vasculature without first priming the catheter. Once the air has been vented from the upstream and downstream portions of the IV catheter system, the primer may be actuated to open a fluid pathway through the primer. With the fluid pathway opened, the priming solution may commence flowing towards the patient's vasculature thereby flushing the blood from the IV catheter system.

  • Patent number: 10525211
    Abstract: An infusion pump device and method for filling a fluidic system of the infusion pump with liquid medicament prior to infusion operation is presented. A control unit causes the infusion pump to: (a) bring a pump to an initial state; (b) switch a valve to a first state connecting a secondary reservoir to a first conduit and a primary reservoir; (c) retrieve medicament from the primary reservoir; (d) switch the valve to a second state connecting the secondary reservoir to a second downstream conduit; (e) expel the secondary reservoir contents into the second downstream conduit; (f) switch the valve to the first state; (g) retrieve the primary reservoir medicament; (h) switch the valve to the second state; and (i) expel the secondary reservoir contents into the second downstream conduit by shifting a piston to the initial position.

  • Patent number: 10525237
    Abstract: An IV catheter system may have a catheter component with a catheter hub, a cannula extending distally from the catheter hub, and a push feature adjacent to the catheter hub. The IV catheter system may also have a needle component with a needle hub, a needle extending distally from the needle hub along an axis, and a grip extending from the needle hub, generally parallel to the axis, with a pull feature. In the insertion configuration, the needle may be positioned within the cannula and the distal end of the needle hub may be seated in a needle port of the catheter hub. In the fluid delivery configuration, the needle may be positioned outside the catheter hub. The push and pull features may be positioned to facilitate manipulation with a single hand to move the IV catheter system from an insertion configuration to a fluid delivery configuration.

  • Patent number: 10500349
    Abstract: This invention is an air block for industrial, medical, and non-medical uses. For example, the air block is connected to the proximal end of a vascular access catheter. The air block is either removably connected to the proximal end of the catheter or it is integral to the proximal end of the catheter. The air block permits introduction of other catheters or instrumentation through its central lumen and on into a lumen of the catheter while minimizing fluid loss or gain into the catheter. The air block further prevents air from entering the catheter and provides for removal of the air or other gas from the central lumen before it can enter the catheter where it could cause harm to the patient. The air block can be attached to various standard proximal catheter terminations including Luer fittings and hemostasis valve outer barrels.

  • Patent number: 10357300
    Abstract: A delivery system is provided that includes a device having a body extending along a longitudinal axis between proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extends through the wall and includes a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a fluid within the proximal chamber out of the first port and the distal plunger moves a fluid within the distal chamber out of the second port to simultaneously actuate a bone filler dispenser. Systems and methods are also provided.
