Apparatuses, Systems, And Methods For Inserting Catheters Having Enhanced Stiffening And Guiding Features

Abstract

A catheter assembly including a multi-lumen catheter, a stylet, and a guide-wire. The multi-lumen catheter includes a first lumen in fluid communication with a first distal opening and a second lumen in fluid communication with a second distal opening. The stylet is designed for insertion through the first lumen, having a length greater than a length of the first lumen such that a distal portion of the stylet can extend distal of the first distal opening. The distal portion of the stylet can include a stylet distal opening, a stylet proximal opening in communication with the stylet distal opening, and an expandable portion. The expandable portion can include a first expansion side and a second expansion side at least partially separable from the first expansion side. The stylet proximal opening can be formed through the first expansion side.
