DUAL LUMEN DIAGNOSTIC CATHETER

摘要

A medical device including both an intraluminal imaging apparatus and dual guidewire lumens is provided, allowing more accurate and stable catheter navigation and treatment delivery. The dual lumen catheter may also include members for increased torsional rigidity, distally located functional measurement sensors, and patterned radioopaque markers for orientation of the dual lumen exits.
