Abstract: A catheter priming apparatus may include a barrier forming a reservoir. Fluid may be disposed within the reservoir. A support structure may be disposed within the barrier. The support structure may include an opening extending through the support structure and a connector configured to couple the catheter priming apparatus to a catheter system. A one-way valve may be coupled to the support structure and configured to allow the fluid to flow out of the reservoir through the connector in response to compression of a portion of the barrier aligned with the opening.

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.

Abstract: A catheter system may include a catheter lumen, first and second electrodes, and a sensor in communication with the first and second electrodes. The sensor may be configured to detect at least one of: a bulk volume of blood within a blood vessel and extravasation of a drug from the blood vessel into soft tissue adjacent the blood vessel. Other catheter systems may include a catheter lumen and a sensing chip coupled to the catheter lumen. The sensing chip may be configured to detect at least one of: a bulk volume of blood within a blood vessel and extravasation of a drug from the blood vessel into soft tissue adjacent the blood vessel.

Abstract: An infusion device is configured to monitor delivery conditions associated with a medication infusion, identify an infusion set used with the infusion device, determine that the delivery conditions modify operation of infusion set, and determine correction factors for modifying an operation of the device based on a modification of the operation of the infusion set by the monitored delivery conditions. According to various implementations, an operating parameter of the infusion device may be modified, including modifying a threshold for when the infusion device will experience an alarm condition.

Abstract: An apparatus for morcellating tissue includes a flexible outer container (1), an electrically conductive mesh (7) disposed within the container, and one or more connections (8, 9) by which the mesh (7) can be energised to form at least a part of a bipolar electrode assembly capable of cutting tissue coming into contact therewith. The mesh (7) includes a first section (14, 17) constituting one or more active electrodes, a second section (15, 18) constituting one or more return electrodes, and one or more insulators (16) separating the first section from the second section. The apparatus includes an elongate shaft (2) from which the flexible outer container (1) can be deployed, and actuators for closing the mesh (7) around tissue to be morcellated, and for deploying and withdrawing the flexible outer container (1) with respect to the shaft (2).
