Acute Central Venous Catheter Symmetric Filler

Abstract

A system includes a catheter and one or more fillers, or plugs, configured to block a lumen of the catheter. The catheter may include an elongate tube having a distal end and defining a plurality of lumens. A distal tip structure may be located adjacent to the distal end. A plug may be configured to be positioned within a first portion of a first lumen of the plurality of lumens proximal the distal tip. The plug may include an oval cross-sectional shape and be formed of a biocompatible polymeric material such as silicone, nylon, polyurethane, polyethylene terephthalate, a latex, a plastic, a thermoset, or a thermoplastic elastomer. The oval cross-sectional shape may have first and a second vertices, where the first plug is configured such that either of the vertices may be positioned near an upper side of the first lumen without causing bulging of a wall of the lumen.
