Abstract: A vascular access device to passively open a fluid path within a vasculature. The vascular access device may include a catheter and a guidewire. The catheter may have a proximal end, a tip, and a length of tubing therebetween. The guidewire may extend along the length of tubing and may include a bent portion. At least a portion of the length of tubing may substantially conform to the bent portion such that the tip of the catheter avoids an obstruction within the vasculature.

Abstract: An intravenous (IV) catheter system may include a catheter adapter having a proximal end and a distal end. The IV catheter system may also include a cannula extending through the catheter adapter. A proximal end of the cannula may include a notch. The IV catheter system may also include a needle hub, which may be coupled to the proximal end of the catheter adapter. The needle hub may include a flashback chamber, which may be in fluid communication with the notch when the IV catheter system is in an insertion configuration.

Abstract: A catheter assembly is provided that includes a catheter, a catheter adapter, a near port connector connected to the catheter adapter port, and an extension set coupled to the near port connector and including a far port connector. The near port connector includes a distal port, a proximal port, and a side port, with the extension set connected to the side port and a split-septum valve provided in the proximal port. The near port connector may be configured to withstand a proximally-directed fluid backpressure of greater than 30 psi to prevent fluid leaks during a fluid injection through the far port connector, or may have a fluid path shut-off attached thereto to selectively close a fluid path through the near port connector and the split-septum valve, to prevent fluid leaks out from the near port connector during a fluid injection through the far port connector.

Abstract: 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.

Abstract: A catheter system 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. A bump may be disposed on the strain relief rib and configured to contact a needle cover. A catheter may be secured within the catheter adapter and extend distally beyond the nose.

Abstract: 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.

Abstract: A catheter assembly (10) comprises a catheter (20), a needle (22) having a sharp distal tip and disposed within the catheter (20), a catheter hub (30) connected to the catheter (20) having the needle (22) passing therethrough, and a housing (70) that encloses the sharp distal tip of the needle (22). An external surface of the catheter hub (30) and an internal surface of the housing (70) each include at least one of a channel member (34) and a raised portion (72) that interfit to restrict motion between the catheter hub (30) and the housing (70).

Abstract: Pinch clamps are provided which generate positive displacement while also preventing rebound. To prevent rebound while providing positive displacement, the upper and lower clamping surfaces may be configured to form a pinch profile along which the tubing is compressed with the pinch point being formed at the distal end of the pinch profile. To further prevent rebound, the lower arm of the pinch clamp can include blocking ribs that interface with the upper clamping surface to prevent distal travelling of the pinch point even if the upper arm is forced into an over-engaged position.

Abstract: 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.

Abstract: An instrument advancement device includes an access connector configured to be connected to a vascular access device, a primary lumen in fluid communication with the access connector, an instrument received within the primary lumen and having a retracted position and an extended position, an advancement member configured to move the instrument between the retracted position and the extended position, and a lumen seal received within the primary lumen and connected to the instrument. The lumen seal defines a space between the lumen seal and the primary lumen when the instrument is in the retracted portion. The lumen seal engages the primary lumen when the instrument is in the advanced position.

Abstract: An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may have a plurality of pores through which the liquid flows, and may be formed of a hydrophilic material that resists passage of air through the pores. The intravenous delivery system may further have a bubble point raising component that raises the bubble point of the anti-run-dry membrane. The bubble point raising component may, in some embodiments, be a high surface energy coating or additive.

Abstract: An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may be secured to a seat of the exterior wall by an attachment component. The attachment component may have various forms, such as a secondary exterior wall that cooperates with the exterior wall to define a drip chamber, a washer positioned such that the anti-run-dry membrane is between the washer and the seat, and an adhesive ring formed of a pressure sensitive adhesive and secured to the anti-run-dry membrane and the seat via compression. Interference features may protrude inward from the exterior wall or outward from the anti-run-dry membrane to help keep the anti-run-dry membrane in place.
