US Patent 11890429 Rapidly inserted central catheter and methods thereof

Rapidly inserted central catheters (“RICC”), and methods thereof. A RICC can include a catheter tube including a first section in a distal-end portion of the catheter tube, a second section in the distal-end portion of the catheter tube proximal of the first section, and a junction between the first and second sections of the catheter tube. The first section of the catheter tube can be formed of a first material having a first durometer. The second section of the catheter tube can be formed of a second material having a second durometer less than the first durometer. The first and second sections of the catheter tube can have a column strength sufficient to prevent buckling of the catheter tube when inserted into an insertion site and advanced through a vasculature of a patient.
