A catheter assembly and/or an introducer may include one or more features configured to guide a probe and/or a catheter distally through a septum. The catheter assembly may include a catheter adapter and the septum. The catheter adapter may include a distal end, a proximal end, and a lumen extending therebetween. In some embodiments, the septum may be disposed within the lumen. The septum may include a proximal surface that is tapered inwardly in a distal direction such that the proximal surface of the septum is configured to guide the probe and/or the catheter distally through the septum. The catheter assembly may be configured to receive an introducer, which may include an introducer element. A proximal end of the introducer element may include another proximal surface that is tapered inwardly in the distal direction such that the other proximal surface is configured to guide the probe or the catheter distally through the septum.

Systems and methods to improve instrument guidance within an intravenous catheter assembly

Inserts can be formed with elution characteristics to cause the inserts to elute an antimicrobial agent when subject to a fluid within a medical device. An insert can be formed with a desired geometry to allow the insert to be compression fit within a medical device to prevent the insert from moving or becoming dislodged once inserted into the medical device. The material may also be hygroscopic so that the insert swells when subject to a fluid thereby enhancing the compression fit of the device within the medical device. In some cases, the material can be reinforced using an internal structure. Inserts can be formed in many ways including by casting, thermoforming, or extrusion. In some cases, the inserts can be formed using a peel-away sleeve or material. The peel-away sleeves can be formed of a non-sticky material which facilitates removal of the inserts once the inserts have cured.

Antimicrobial inserts for medical devices

A vascular access device may include a housing, which may include a proximal end, a distal end, and a slot. The distal end of the housing may be configured to be coupled to a catheter assembly. The vascular access device may also include an instrument disposed within the housing. The instrument may include a catheter or a probe. The instrument may include a proximal end and a distal tip. The proximal end of the instrument may extend through the slot and may be configured to move along the slot to move the instrument from a proximal position to a distal position. In response to movement of the proximal end of the instrument from the proximal position to the distal position, the catheter may be advanced beyond the distal end of the housing into the catheter assembly and/or vasculature of a patient.

Extension housing a probe or intravenous catheter

A flush syringe for use in maintaining intravenous catheters, wherein the flush syringe can more efficiently and effectively flush the catheters by providing a pulsating, pulsatile, and/or pulsative flow of fluid that can be produced using momentum of the fluid moving. A steady force applied to a plunger while flushing can provide the pulsating, pulsatile, and/or pulsative flow of the fluid to the catheters.

Pulsatile or resonating flush syringe

An integrated vascular access device can include strain relief features to minimize the likelihood of the extension tubing becoming kinked during use. These strain relief features can be configured at both ends of the extension tubing to minimize the likelihood of kinking at the interfaces to the catheter adapter and luer adapter. To provide strain relief at the catheter adapter end of the extension tubing, an interface formed of a flexible material can be aligned with an extension of the catheter adapter into which the extension tubing inserts. The interface can be integrated into a stabilization platform or formed separately from a stabilization platform. To provide strain relief at the luer adapter end of the extension tubing, a flexible spacer can be coupled to a distal end of the adapter and have a distal portion that is positioned around the extension tube.

Extension tubing strain relief

Various embodiments of an antimicrobial insert for a stopcock medical connector are provided. More specifically, the present invention relates to an antimicrobial insert that is seated within at least a portion of the annular bore of the connector's tap, wherein fluid within the annular bore contacts the antimicrobial insert, thereby preventing microbial proliferation within the stopcock medical connector.

Antimicrobial inserts for stopcock medical connectors

A vascular access device may be an integrated catheter. The vascular access device includes a catheter and catheter adapter having a catheter hub and side port. The contact angle of a probe is greater than 90 degrees. The entrance angle of a probe entering the catheter hub from the side port may be less than 45 degrees. The vascular access device may include a component configured to direct the path of a probe towards the catheter opening. The component may be a protrusion extending into the lumen of the side port, internal fluid passageway, and/or extension tube, or a septum within the catheter hub. The vascular access device includes an access adapter in fluid communication with the side port and permitting insertion of a probe into the catheter through the side port with or without a separate luer adapter. Methods of using a vascular access device are further disclosed.

Integrated peripheral intra-venous catheter with improved extension tube port probe access

A catheter assembly may include a catheter adapter, which may include a body and a nose extending distally from the body. The nose may be generally cylindrical. A strain relief rib may be disposed on the nose. The strain relief rib may be constructed of a flexible material. The catheter assembly may also include a needle secured within the catheter adapter and extending distally beyond the nose. The catheter assembly may further include a needle cover, which may be removably coupled to the nose of the catheter adapter. An inner surface of the needle cover may be smooth and may contact the strain relief rib.

Needle cover retention

In some embodiments, a catheter system may include a catheter adapter having a distal end, a proximal end, and a lumen extending there between. In some embodiments, the catheter system may also include a catheter extending distally from the distal end of the catheter adapter, an extension tube, and a connector coupled to a proximal end of the extension tube. In some embodiments, a distal end of the extension tube may be coupled to the proximal end of the catheter adapter. In some embodiments, the connector, the extension tube, the lumen, and the catheter may form a straight pathway for delivery of an instrument to the catheter system. In some embodiments, an extension set for a catheter assembly may include the extension tube, the connector coupled to the proximal end of the extension tube, and another connector coupled to the distal end of the extension tube.

Catheter system with remote instrument delivery

PIVCs with extension sets can include one or more flow diverting features for maximizing the amount of flushing that occurs within the interior of the catheter adapter. These flow diverting features can therefore minimize the amount of residual blood, medicament, or other fluid that may exist within the catheter adapter after the PIVC has been flushed via the extension set. The flow diverting features may be in the form of structural modifications to the side port of the extension set, separate components that are contained within the side port or catheter adapter, integrated components within the side port or catheter adapter, other features or some combination of any of these features.

Peripheral intravenous catheters having flow diverting features

Various embodiments of an antimicrobial stopcock medical connector is provided. More specifically, the present invention relates to a stopcock tap having fluid channels provided on portions of the outer surface of the stopcock tap, whereby fluid bypasses the stopcock through the fluid channels by flowing between the outer surface of the stopcock tap and the inner surface of the stopcock housing. Some embodiments further comprise an antimicrobial coating or insert that is provided in the one or more fluid channel, whereby fluid flowing through the fluid channels contacts the antimicrobial coating or an antimicrobial agent that is eluted from the antimicrobial coating. Further still, some embodiments of the present invention comprise an antimicrobial groove that is positioned opposite the fluid channel, whereby when the stopcock is in an 'off' position, the antimicrobial groove contacts fluid within a blocked port thereby preventing microbial growth therein.
