A set connector system for venting a gas from a fluid reservoir of a fluid infusion device is provided. The set connector system includes a connector system having a first body section coupled to a second body section. The first body section defines a bore in communication with a chamber and a counterbore of the second body section to define a fluid flow path from the fluid reservoir. The chamber of the second body section is in fluid communication with a vent subsystem defined through the second body section. The vent subsystem terminates in an outlet, and the vent subsystem directs gas in the fluid flow path through the second body section to the outlet.

Bubble traps for use in medical fluid lines and medical fluid bubble trap systems are disclosed herein. In some embodiments, the bubble trap is configured to trap gas (e.g., air) that flows into the bubble trap from a fluid line. In some embodiments, the bubble trap includes an inlet and an outlet and a chamber between the inlet and the outlet. For example, in some embodiments, the bubble trap is configured to inhibit gas from flowing into the outlet once gas flows into the chamber from the inlet. In some embodiments, the bubble trap is in fluid communication with a source container, a destination container, and/or a patient.

A medication injection device includes a barrel and a plunger disposed to dispense a fluid from the barrel. A dosage tracking system is coupled to output data indicative of the fluid dispensed. A controller is disposed within the medication injection device and coupled to receive the data from the dosage tracking system. The controller includes logic that when executed by the controller causes the controller to perform operations including determining, based on the data, whether an air shot event occurred while dispensing the fluid.

A thrombectomy catheter deployment for operation of a thrombectomy catheter may include a stand alone drive unit and a disposable pump/catheter assembly which is manually placed into a carriage assembly in the drive unit. The pump/catheter assembly may have a plurality of preconnected components including a tubular structure and a thrombectomy catheter connected thereto. A barcode reader may sense specific operational data pertaining to an individual pump and may provide an interface for operation of the reciprocating linear actuator.

An ambulatory infusing device including a housing, a reservoir defining an interior volume, a wall associated with the housing and having an inner surface that faces into the reservoir interior volume, and a filter assembly. The filter assembly may include a filter assembly housing with a housing filter portion having a free end associated with the inner surface of the wall and a filter supporting volume that extends to the free end of the housing filter portion, and a filter located within the filter supporting volume that extends to at least the free end of the housing filter portion.
