Vascular Imaging with Carbon Dioxide: Confidence in a Safe, Efficacious, User-Friendly System

Area of Science:

• Medical Imaging
• Vascular Interventions
• Medical Device Technology

Background:

• Carbon dioxide (CO2) has a long history as an imaging agent, with intravascular use dating back to the 1960s.
• Previous limitations in imaging technology and safe delivery systems hindered the widespread adoption of CO2.
• Cumbersome and non-user-friendly delivery methods created an aversion among clinicians, despite CO2's advantages.

Purpose of the Study:

• To introduce and evaluate a novel, user-friendly delivery system for intravascular carbon dioxide (CO2).
• To address the historical challenges and perceived risks associated with CO2 administration in medical imaging.
• To promote the increased utilization of CO2 as a safe and effective intravascular imaging agent.

Main Methods:

• Development of the CO2mmander/AngiAssist delivery system, a compact, closed, and pre-assembled unit.
• Integration of a proprietary K-valve to prevent CO2 overload and ensure precise delivery.
• Utilizing one-way valves and a complete setup to eliminate operator error and air contamination.

Main Results:

• The new system offers a simple, safe, and effective method for administering non-compressed CO2.
• Elimination of assembly requirements and user-friendly design reduce the aversion to using CO2.
• The system's design inherently prevents CO2 overload, operator error, and air contamination.

Conclusions:

• The CO2mmander/AngiAssist system represents a significant advancement in CO2 delivery technology.
• This simplified and safer approach is expected to drive greater use of intravascular CO2.
• Increased use of CO2 will ultimately translate to enhanced patient care in diagnostic and interventional procedures.
