A device to couple a vascular access device to a medical device may include a body, a spring, and a housing. The body may include a distal end, a proximal end, and a lumen extending through the distal end and the proximal end. The proximal end of the body may include a connector. The housing may be coupled to a proximal end of the spring and may enclose the connector. A distal end of the spring may be coupled to the body. The housing may include a flap, which may include an antimicrobial compound. When the housing is disposed in a proximal position, the flap may cover the connector, the antimicrobial compound may contact the connector, and the spring may be uncompressed. In response to movement of the housing from the proximal position to a distal position, the spring may be compressed and the flap may open.

A method to manage flushing of a catheter assembly may include providing a clamp for a fluid tube configured to be coupled to the catheter assembly. The clamp may include a sensor configured to detect the clamp is closed. The method may include starting a timer in response to the sensor detecting the clamp is closed. The method may include providing an alert in response to the timer reaching a predetermined duration of time. The alert may indicate to a clinician that the catheter assembly should be opened and flushed, which may prevent occlusion of the catheter assembly.

A system, method, and article for delivering an antimicrobial agent into the lumen of a trans-dermal catheter are disclosed. In an embodiment, the system comprises an elongate member configured for insertion into a lumen of a catheter, and the elongate member containing an antimicrobial. In the alternative an antimicrobial agent can be placed on an interior surface of a retaining ring.

An anti-clog suction tip apparatus includes a suction tip having a suction opening and an interior defining a suction channel. An ejection wire channel extends to a wire exit opening into the suction channel that is located proximate the suction opening. An ejection wire including a ball tip at an end thereof occupies the ejection wire channel and is transitionable between a retracted configuration and an advanced configuration such that, in the retracted configuration, the ejection wire including the ball tip is retained within the ejection wire channel and does not obstruct suctioning of debris through the suction channel; and in the advanced configuration, the ball tip of the ejection wire does not extend more than three millimeters beyond the suction opening.

An antiseptic medical cap that may include a base, a sidewall, and a chamber configured to receive a proximal end of a medical fluid port having an opening. The antiseptic medical cap, in some instances, may include an insert having a gas-releasing anti-microbial compound and/or include a nitric oxide-releasing system that is configured to be positioned at least partially through the opening of the medical fluid port when the antiseptic medical cap receives the proximal end of the medical fluid port into the chamber.

A combination flush catheter and selective catheter as one convertible catheter and methods of using the same. The selective catheter may be a reverse curve or guide catheter. The additional steps of removal of the flush catheter and re-insertion of the selective catheter may be eliminated, reducing the possibility of errors and making the procedure smoother and shorter.

A patency device for catheter assemblies and other elongate tubular devices used for establishing access to an interior body portion of a patient is disclosed. The patency device establishes and preserves patency of one or more lumens defined by the catheter assembly by providing impulses of positive pressure to fluid disposed in the lumen of the catheter assembly. In one embodiment, the patency device comprises a fluid reservoir configured to provide a fluid path to at least one lumen of the catheter assembly, and a pressure input portion. The pressure input portion is configured to provide pressure for one or more impulses of positive pressure to a fluid disposed within the lumen. The impulses are configured to dislodge occlusions that may have formed in the lumen. A negative pressure can then be provided to the lumen to aspirate the occlusion.

A syringe assembly including: (1) a syringe barrel defining a chamber; (2) a plunger mounted in the chamber and moveable with respect to the barrel; and (3) a cap holder assembly containing a cap and an absorbent material removably attached to the syringe.

Disclosed is a chest drainage system which reduces or eliminates pooling of blood/liquid and/or clogging/clotting in the drainage tube. Generally, the chest drainage system continuously monitors chest tube status and clears pooled liquid when necessary to restore negative pressure to the chest. The system may include a valve device which is located between the patient's chest tube and drainage tube and may be used with any standard chest tube. The chest drainage system also includes a controller for monitoring the pressure at or near the valve device and/or at or near the suction device, and possibly a pump for assisting in clearance of pooled liquid and/or clots. The controller may also control the valve device and/or suction device in response to pressure signals.

A flushing system for a catheter, in particular for a catheter of a catheter pump, comprising a supply line having a pump section, a discharge line having a pump section and a pump, wherein the diameter of the pump section of the discharge line is smaller than the diameter of the pump section of the supply conduit, the pump interacts with the pump section of the supply line for supplying flushing fluid to the catheter, and the pump interacts with the pump section of the discharge line for discharging flushing fluid from the catheter.
