Abstract: A catheter assembly may include a catheter, catheter adapter, needle, needle guard, and housing. The housing may be coupled to the needle guard and disposed within a lumen of the catheter adapter. The needle guard may include first and second resilient arms, which may include first and second curved portions, respectively. When the needle is in a ready position, the first and second curved portions may be urged by a shaft of the needle into retaining contact with an inner wall of the catheter adapter. When the needle is in the retracted position, the shaft may no longer bias the first and second resilient arms outwardly such that the retaining contact between the first and second curved portions and the catheter adapter is released, and the housing and the needle guard enclose a distal tip of the needle.

Abstract: A safety catheter assembly that may be a closed system catheter (CSC) has a seal member proximal a septum in the catheter hub. In a first embodiment, the seal member may be a cylindrical sleeve whereto a locking portion of a needle clip is positioned to fixedly hold the needle clip inside the catheter hub in a ready state. In a second embodiment, the needle clip is housed in a substantially cylindrical seal member. The seal member with the needle clip therein and the catheter hub are fixedly coupled together in the ready state. In a third embodiment, a retainer member at the catheter hub couples the needle clip to the catheter hub in the ready state and the seal member is distal the retainer member. In all the embodiments, the seal member may act as a reservoir for fluid in the interior cavity of the catheter hub that may back flow past the septum.

Abstract: A shield for a needle of a peripheral intravenous catheter or other IV catheter system is provided. The shield may be formed of a single piece of material that may be bent to form a top portion, a bottom portion, a proximal portion, a top distal portion and a bottom distal portion. The proximal portion may form a proximal needle opening and the top or bottom distal portion may form a distal needle opening to allow a needle to extend through the shield when the shield is positioned within the lumen of a catheter adapter. When the distal tip of the needle is withdrawn proximally, the shield may transition from an unlocked position to a locked position in which the distal tip will be retained within the shield.

Abstract: A catheter insertion device that allows for single-handed insertion of the catheter within the vasculature of the patient is disclosed. The catheter insertion device includes a handle, a needle cannula partially within the handle, a guidewire partially within the handle and the needle cannula, and a first actuator connected to the handle and the guidewire. The guidewire is movable relative to the handle in a distal direction away from the handle, and in a proximal direction towards the handle. A catheter assembly is removably coupled to the handle and is configured to slide on the needle cannula. A catheter hub may be connected to a proximal end of the catheter, and a catheter advancer base may be releasably connected to the catheter hub. The catheter insertion device may also include a needle support pivotally connected to the handle for supporting the needle cannula on a cantilever portion thereof.

Abstract: A catheter insertion device includes a housing, a needle coupled to a needle hub, a catheter pre-disposed over the needle, a guidewire pre-disposed in a lumen of the needle, a guidewire advancement assembly configured to distally advance the guidewire with respect to the needle, and a catheter advancement assembly configured to distally advance the catheter with respect to the needle. The needle hub can be fixed to an interior of the housing with a distal section of the needle extending from the housing. The catheter advancement assembly can include a tail portion to engage the needle hub in order to prevent movement of the catheter advancement assembly. The catheter insertion device can also include a flash indicator with an elongate channel in fluid communication with the needle lumen. The elongate channel can include a viewable pathway to indicate to a user that the needle tip is within a blood vessel.

Abstract: A catheter system may include a needle assembly coupled to a catheter adapter. The needle assembly may include a housing, an introducer needle, a proximal opening, a distal opening, and a needle tip shield feature. A distal tip of the introducer needle may be configured to be proximally withdrawn from a first position to a second position in which a bump feature of the introducer needle contacts and is prevented from moving through the proximal opening. In response to withdrawal of the distal tip proximally from the second position to a third position, the housing may move proximally, and the needle tip shield feature may be released to block the distal opening. The needle tip shield feature may not contact the introducer needle when the distal tip moves proximally from the first position to the second position and from the second position to the third position.
