A catheter assembly may include a catheter adapter, which may include a distal end, a proximal end, and a lumen extending through the distal end and the proximal end. The catheter assembly may include a catheter secured within the catheter adapter and extending from the distal end of the catheter adapter. The catheter adapter may be configured to move between a first position and a second position. In response to the catheter adapter moving from the first position to the second position, an angle of the catheter adapter with respect to an insertion surface may be configured to increase, which may improve patency of the catheter assembly and alignment of a fluid path of the catheter assembly with vasculature of a patient.

Catheter assembly with angle changing and related methods

An IV device assembly may include a lumen forming a fluidic channel within the IV device assembly. The lumen may be fluidically coupled to a vascular access device (VAD) coupler via a funnel coupler, and an IV device assembly coupler at a proximal end of the lumen. The IV device assembly may also include one or more of the following: a collapsible sleeve formed coaxially around a first portion of the lumen and mechanically coupled to the funnel coupler, a probe formed along a second portion of the lumen within the collapsible sleeve and into the VAD coupler, a translation handle that translates the probe out of a distal end of the VAD coupler, and a fixed grip formed around the lumen to maintain a position of the IV device assembly relative to the translation handle.

An IV catheter device can include or being configured to employ a probe assembly having an integrated fluid flushing mechanism. The probe assembly can be configured in a variety of ways to cause flushing fluid to be injected through a fluid permeable structure of the probe as the probe is advanced distally from a catheter. In this way, the fluid permeable structure can be kept clear of any occlusion that may otherwise form. With the probe extending distally from the catheter, a blood sample may be collected.

A clip used in a catheter assembly, the clip comprising a first leg and a second leg angularly connected to the first leg, wherein the second leg includes a substantially U-shaped spade configured to engage a needle housing of the catheter assembly to secure the clip to the needle housing.

Needle capture safety interlock for catheter

A blood collection device may include a tubular container, which may include a closed end and an open end opposite the closed end. The blood collection device may include a plug sealing the open end and a partition within the tubular container. The partition may separate the tubular container into a first chamber and a second chamber. The first chamber and the second chamber may be evacuated such that a pressure within the first chamber and a pressure within the second chamber are lower than ambient pressure and equal to each other. In response to blood being drawn into the first chamber, the pressure within the first chamber may increase, and the partition may slide towards the closed end such that a size of the first chamber increases and a size of the second chamber decreases.

Multi-chamber blood collection device and related systems and methods

A catheter adapter may include a distal end, a proximal end, a lumen extending between the distal end and the proximal end, and a side port. A central axis of a fluid path extending through the side port may be disposed at an angle with respect to a longitudinal axis of the catheter adapter. The angle may be less than 45°. Additionally or alternatively to the angle being less than 45°, the catheter adapter may include a wedge and/or an insert configured to facilitate instrument delivery to the catheter assembly via the side port.

Systems and methods of facilitating instrument delivery to a catheter assembly

A probe advancement device may be configured to couple to a catheter assembly. The probe advancement device may include a flexible housing, which may include a proximal end and a distal end. The probe advancement device may include a probe advancement element coupled to the proximal end of the flexible housing. The probe advancement element may include a probe extending in a distal direction within the flexible housing. The flexible housing may be configured to collapse along an axis in response to the probe being advanced in the distal direction. The probe may include a tube for blood collection, a guidewire, or another suitable element.

Probe advancement device and related systems and methods

A catheter system may include a catheter adapter and a wing extending outwardly from the catheter adapter. The wing may include a groove or slot. The catheter system may include a needle hub and a paddle extending outwardly from the needle hub. The paddle may include an extension disposed within the groove or the slot to reduce axial movement between the catheter adapter and the needle hub, which may be advantageous during insertion of the catheter system into a patient. The extension may be removable from the groove or the slot to allow axial movement between the catheter adapter and the needle hub during removal of the needle hub from the catheter adapter, for example. The paddle and/or the wing may include a shape to reduce axial movement between the catheter adapter and the needle hub, which may also be advantageous during insertion of the catheter system.

Providing resistance to separation of a catheter adapter and a needle hub

An extravascular system is provided which includes a catheter adapter having a blood control septum configured to control flow of a fluid through the catheter adapter, the catheter adapter further having a catheter configured for intravenous insertion. The extravascular system further includes a septum activator slidably inserted within the catheter adapter and configured for advancement through the blood control septum to provide a fluid pathway through the blood control septum. Further still, the extravascular system includes an external safety mechanism comprising a needle hub and a needle shield interconnected via a tether, wherein the needle shield includes a safety clip that is configured to retain a sharpened end of the introducer needle within the needle shield. Some implementations further comprise an access port forming a portion of the catheter adapter and providing selective access to the lumen of the catheter adapter.

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 needle is provided that can be used for introducing or aspirating fluids to a patient or as an introducer needle for positioning and inserting a catheter, such as a peripheral IV catheter into a patient. The needle can be an introducer needle that extends from the distal end of the catheter during insertion. The needle has an insertion tip with a configuration to assist penetration into a vein with a reduced incidence of injuring the inner surface of the vein or inadvertently passing through side wall of the vein. The needle tip can be farmed with a curved distal end surface where the pointed tip is spaced radially inward relative to the outer surface of the needle. In another embodiment the needle tip can have a reverse beveled surface having an axial length, angle, and curvature to assist in penetrating the vein with a reduced incidence of transfixing the vein.

Needle and catheter insertion device

A delivery device to deliver a tubular instrument into a catheter extending distally from a catheter adapter. The delivery device may include a housing configured to couple to the catheter adapter. The delivery device may include a tubular instrument configured to insert through the catheter. The tubular instrument may include a distal end, a proximal end, and a lumen extending between the distal end and the proximal end. The distal end may include a distal tip, which may be closed. The proximal end may be secured within the housing. The tubular instrument may be configured to advance distally with respect to the housing. A portion of the distal end proximate the distal tip may include a first material and maybe stiffer than the distal tip, which may include a second material. A durometer of the first material may be greater than a durometer of the second material.
