Guidewires include a distal section, a proximal section and a middle section disposed between the distal section and the proximal section, wherein the middle section has a flexural stiffness that is greater than a flexural stiffness of both of the distal section and the proximal section. The distal section is configured for insertion into a vasculature of a patient. A diameter of the middle section may be greater than a diameter of the distal section. The guidewires may include a tapered distal transition portion disposed between the distal section and the middle section and a solid core wire extending a length of the guidewires, the solid core wire including a first diameter extending along the distal section, a second diameter extending along the proximal section, and a third diameter extending along the middle section, wherein the third diameter is greater than the first diameter and second diameter.

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.

Disclosed herein is a catheter, which in some embodiments includes a distal section configured to enter a skin insertion site. The distal section can include a tapered junction having one or more dilation structures configured to dilate the skin insertion site. The distal section can further include a distal portion extending from a distal end of the tapered junction, the distal portion having a diameter smaller than a proximal portion of the catheter. In combination, the tapered junction, the one or more dilation structures, and the specific actions of the user urging the catheter into the insertion site can result in an improved fit of the catheter in the insertion site.

Passive dilation in catheter insertion systems

Embodiments disclosed herein are directed to catheter placement systems including distally extendable support devices. When placing elongate catheters advanced insertion systems are required to maintain a 'touch-free' insertion. Further longer needles are desirable to access deeper veins or penetrate deeper surface tissues. Distally extendable support devices provide columnar support to one of the elongate catheter or the needle to prevent buckling or kinking of the catheter, and maintain the needle tip within a predetermined bending arm distance. This prevents the user from contacting one of the needle or the catheter directly to provide additional support, maintaining a “touch-free” insertion.

Optimized structural support in catheter insertion systems

Elongate blood flash flow paths can be detrimental to the operation of catheter placement systems by delaying the indication time, reducing the efficacy of the vacuum, or increasing the chance of clotting. Catheter placement systems with reduced blood flash fluid paths include blood flash indicators having a proximally slidable syringe barrel and plunger that is fixedly attached to the system housing. By reversing the operation of the blood flash indicator syringe, the clinician maintains the advantages of a visual and tactile feedback while shortening the blood flow path between the needle tip and syringe barrel. Catheter placement systems also include a needle interface structure configured to further shorten the blood flash fluid path.
