  • Publication number: 20230128853
    Abstract: A guidewire stabilization mechanism for a catheter placement system can include an actuator button that can be actuated by the user to grip the guidewire in a locked position. With the guidewire locked relative to a housing of the stabilization mechanism a user can detach a needle hub from the housing and withdraw the needle proximally. A portion of the guidewire can pass through a needle slot to disengage the needle from the guidewire. The stabilization mechanism can prevent the guidewire from being dislodged from the vasculature as the needle is withdrawn. The stabilization mechanism can be biased towards the unlocked position, towards the locked position, can be bistable in both the locked and unlocked positions, or can be activated by the removal of the needle.

  • Publication number: 20230126869
    Abstract: The distal tip structure of a rapidly insertable central catheter (RICC) can be required to perform different functions from that of the remaining, multi-luminal section, of the RICC catheter. As such, the catheter body can be formed of a first material and the distal tip structure can be formed of a second material. Forming the RICC requires joining these two materials while maintaining a smooth abluminal surface. A bifurcated plug including a second material can be placed within a first lumen or second lumen of the catheter body. A mandrel can be placed within a third lumen. The assembly can then be placed within a die to plastically deform the bifurcated plug into a distal tip structure. Advantageously, only a single structure is required to plug the lumen and form the distal tip structure, reducing complexity and associated costs.

  • Publication number: 20230096740
    Abstract: Disclosed are insertion assemblies of rapidly insertable central catheters (“RICCs”) and methods thereof. For example, a RICC insertion assembly can include a RICC, an introducer needle, an access guidewire, and a coupler assembly coupling the foregoing together. The introducer needle can include a needle hub over both a sheath and a needle shaft. The sheath can seal a needle slot except for that under a sheath opening. A distal end of the access guidewire can be disposed in the introducer needle just proximal of a needle tip. The coupler assembly can include a nose piece and a tail piece coupled together. The tail piece can include an extension arm by which a proximal end of the access guidewire is held. The access guidewire can enforce a loop in the access guidewire over which the RICC is disposed, thereby keeping the RICC insertion assembly in a relatively compact form.

  • Publication number: 20230100482
    Abstract: A catheter assembly includes a peripheral intravenous (“PIV”) portion that provides expedited vascular access. The catheter assembly includes an elongate catheter body defining a first lumen and includes a CVC portion, a transition portion, and a PIV portion. The PIV portion defines a relatively smaller diameter, a tapered tip, and a lumen configured to receive a needle. The needle extends through a needle access aperture, disposed through a side wall of the catheter body, through the PIV lumen, to a point beyond a distal end of the catheter body. A clinician accesses a vasculature using the needle and the PIV portion. The needle is then removed and a guidewire advanced through the lumen of the catheter body and the PIV portion into the vasculature. The CVC portion is then advanced over the guidewire into the vasculature, self-dilating the insertion site as the transition portion enters the vasculature.

  • Publication number: 20230012848
    Abstract: Embodiments disclosed herein are directed to a securement device including a retainer defining a channel and at least one mounting wing extending therefrom. The mounting wing extends distally of an insertion site a skin surface adjacent to the insertion site to prevent “rocking” or “pistoning.” The mounting wing further includes channels of reduced thickness configured to impart malleable properties on the mounting wing. This can allow the mounting wing to be shaped to fit different portions of the patient. The retainer further includes various locking and anti-rotational features to guide the catheter into position within the retainer and further prevent “rocking” or “pistoning.” The securement device also includes a protective pad to inhibit abrasions from a medical line, spin nuts, and the like, and includes a clasping feature to retain a portion of the release liner to prevent obstructing ingress/egress of the catheter.
