CO₂ Insufflation Devices

Specifically designed to provide a controlled high flow of turbulence free CO2 into the thoracic cavity during open heart surgery. 

During surgery, the sternotomy unavoidably exposes the thoracic cavity to air and particles that can carry bacteria with them, increasing the risk of airborne contamination that leads to post-operative infections.

The CarbonAid® is an innovative carbon dioxide insufflation device.

The CarbonAid® is for full sternotomy sized thoracic wounds @ 10  l/min CO2 flow.

The CarbonAid® and CarbonMini® are innovative carbon dioxide insufflation devices that can provide a protective, bacteriostatic environment inside the chest to prevent microscopic particles from entering the cavity. Also to provide a controlled and even cascade of CO2 that assists with de-airing to prevent air embolism.

The CarbonMini® is for smaller wounds @ 2-8  l/min CO2 flow.

The research and development into the CarbonAid and CarbonMini’s unique diffuser make them technically superior to other devices on the market. The CarbonAid® and CarbonMini® can deliver a high CO2 gas flow without any turbulence1,2,3,4 and as a result, this creates a 100% CO2 atmosphere inside the thoracic wound area, preventing air embolism from occurring.

Both feature a malleable shaft to maintain position, and an innovative sponge tip that continues to deliver a laminar flow of CO2 at a sufficient rate both during and after being subjected to liquid (i.e. blood, saline). Each product contains a highly bacterial filter and a long tubing for connection to a CO2 flow meter.

Chalice Medical Ltd. are the UK distributor of the CarbonAid® and CarbonMini®, supplied by Cardia Innovation AB.
