An IV catheter-placement device and method thereof. The IV catheter-placement device can include a cartridge and a case fixedly disposed over the cartridge. The cartridge can include a barrel having a release button, a spring-loaded needle extending from the barrel, and an IV catheter including a catheter hub slidably disposed over the needle. The case can include a deployment button configured to slide the IV catheter over the needle. The deployment button can also be configured to press the release button when the deployment button slides into the release button. A spring compressed between a needle hub and a distal-end portion of the barrel can be released when the deployment button slides into the release button. An entirety of the needle is subsequently launched into a needle cavity of the barrel.

An intravenous catheter device may include a guidewire for actively repositioning the catheter tip. A guidewire assembly may be configured to enable a clinician to actively reposition the catheter tip by moving proximal ends of segments of the guidewire. By repositioning the catheter tip, the guidewire assembly may facilitate the collection of a blood sample or the injection of a fluid through the catheter even in instances when the catheter tip has become occluded.

A catheter assembly may include a catheter adapter, which may include a body and a side port extending outwardly from the body. The body may include a distal end, a proximal end, and an inner surface extending through the distal end and the proximal end and forming a lumen. The catheter assembly may include one or more components to facilitate flushing of the catheter assembly. For example, an angle of the side port with respect to a longitudinal axis of the body may be adjustable. The catheter assembly may include a catheter extending distally from the distal end of the catheter adapter. The catheter assembly may include a septum disposed within the lumen proximal to a side port pathway extending through the side port and in fluid communication with the lumen.

An intravenous catheter device can have a probe with a selectively permeable distal end. The probe can be inserted through a catheter while the catheter is positioned intravenously to facilitate fluid flow into or out from the catheter such as by removing an occlusion or repositioning the catheter. Due to its selective permeability, the distal end of the probe can minimize the likelihood of the probe becoming occluded while it is inserted intravenously and may provide control over the rate of fluid flow into or out from the catheter.

A catheter assembly may include a catheter adapter, which may include a distal end, a proximal end, a lumen extending through the distal end of the catheter adapter and the proximal end of the catheter adapter, and a side port disposed between the distal end of the catheter adapter and the proximal end of the catheter adapter. The catheter assembly may include a catheter extending distally from the distal end of the catheter adapter. The catheter assembly may include a valve disposed within the lumen. The catheter assembly may include a retainer element configured to secure the annular valve within the lumen. The retainer element may be disposed within the lumen proximal to a proximal end of the annular valve.

A needle assembly of a catheter system may include one or more features to facilitate flashback confirmation of catheterization while also preventing buildup of positive pressure within a flashback chamber of the needle assembly. The needle assembly may include a plug, which may include an aperture for receiving an introducer needle. A proximal opening of the introducer needle may be accessible from the proximal end of the needle hub. The plug may include a vent between an outer surface of the plug and an inner surface of the needle hub to prevent the buildup of positive pressure. The plug may include an extended distal end that reduces a volume of the flashback chamber. The plug may include a window in fluid communication with a notch of the introducer needle. Blood may flow from the notch into the flashback chamber with a reduced volume via the window of the plug.

A catheter assembly (10) comprises a catheter (22), a needle (12) having a sharp distal tip, a catheter hub (14) housing the catheter (22), the catheter hub (14) having a collar (34) including a notch (36), a needle shield (20) connected to the catheter hub (14) when the needle (12) is in a first position, and a clip (40) disposed in the needle shield (20) that cooperates with the needle (12), wherein the clip (40) engages the catheter hub (14) in the first position of the needle (12), and the clip (40) disengages the catheter hub (14) via the notch (36) when the needle (12) is retracted to a second position to cover at least a portion of the needle (12). The clip (40) is mounted in the outer housing (38) of the needle shield (20) via a spade (66) having an outer wall (70) exposed to the outside of the needle shield (20), in order to reduce the overall width of the needle shield (20).

A catheter assembly may include an over-the-needle catheter and introducer needle. The catheter may include a distal tip and an elongate tubular portion proximate the distal tip of the catheter. The distal tip may be constructed of a first material and may include at least a portion of a stepped surface. The tubular portion may be constructed of a second material having a harder durometer than the first material. The introducer needle may include a needle feature having another stepped surface configured to abut the stepped surface of the catheter when the introducer needle is in an insertion position such that proximal movement of the distal tip of the catheter relative to the introducer needle is inhibited.

Rapidly insertable central catheters (“RICCs”), introducers, and insertion devices including combinations and methods thereof are disclosed. For example, a RICC system can include an introducer and a RICC insertion assembly including a RICC assembly disposed in a RICC insertion device. The RICC assembly can include a RICC, an access guidewire, and a splittable casing over a catheter tube of the RICC and the access guidewire forming a longitudinal composite. The RICC insertion device can include a frame and a nose cover forming a split channel that splits away from a through channel of a nose of the frame. The RICC insertion device can be configured for advancing the RICC assembly by rolling the longitudinal composite across roller wheels disposed in the frame. The through channel can be configured for advancing the catheter tube therethrough while the split channel can be configured for both splitting and passing the splittable casing therethrough.

A catheter assembly may include a catheter adapter, which may include a body and a side port extending outwardly from the body. The body may include a distal end, a proximal end, and an inner surface extending through the distal end and the proximal end and forming a lumen. An angle of the side port with respect to a longitudinal axis of the body may be adjustable. The catheter assembly may include a catheter extending distally from the distal end of the catheter adapter. The catheter assembly may include a septum disposed within the lumen proximal to a side port pathway extending through the side port and in fluid communication with the lumen.
