RAPIDLY INSERTABLE CENTRAL CATHETERS INCLUDING CATHETER ASSEMBLIES AND METHODS THEREOF

摘要

Rapidly insertable central catheters ("RICCs") including catheter assemblies and methods thereof are disclosed. A RICC assembly (100) can include a RICC (102), an introducer (104), and a coupling system (106) configured to couple the RICC and the introducer together. A catheter tube (108) of the RICC can include a side aperture (114) in a distal-end portion of the catheter tube, which opens into an introducing lumen (118) extending from the side aperture to a distal end of the RICC. The introducer can include an introducer needle (128) having a cannula (138). The coupling system can include a distal coupler (146) slidably attached to the catheter tube proximal of the side aperture. The cannula extends through a longitudinal through hole of the distal coupler, through the side aperture of the catheter tube, along the introducing lumen of the catheter tube, and through the distal end of the RICC when the RICC assembly is in a ready-to- deploy state thereof.
