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.

Abstract: Disclosed herein are couplers and assemblies thereof for rapidly insertable central catheters (“RICCs”). For example, an introducer-needle assembly for a RICC can include an introducer needle and a coupler coupled therewith. The introducer needle can include a needle having a longitudinal needle slot extending from a proximal portion of the needle shaft through a distal needle tip. A sheath can be over the needle shaft sealing the needle slot thereunder except for a portion of the needle slot under a sheath opening in a proximal portion of the sheath. A needle hub can include a distally extending needle-hub extension arm over the proximal portions of the needle shaft and sheath. The needle hub can also include a needle-hub portion of a RICC clip configured to hold a portion of the RICC therein. The coupler can include a complementary coupler portion of the RICC clip connected to a coupler housing.

The coupler can include a coupler housing and an extension arm connected to the coupler housing. The needle-hub clip can be clipped onto the coupler housing in at least a ready-to-deploy state of the coupler assembly. The extension arm can be configured for attaching a proximal end of an access guidewire thereto.
