The First Automated Clog Clearance System for 

Cardiac Surgery



Thoraguard in Cardiac Surgery


Automated Line Clearing

First and only automated clog clearance system clears proprietary 20 Fr. chest tube every 5 minutes, with no human  manipulation needed

Digital Fluid Measurement

Digitally measures and displays hourly drainage volume and trends to provide objective data for patient monitoring


of cardiac surgery patients experience clogged chest tubes, increasing the risk of blood build-up


Sub-Optimal Drainage

Complications from fluid build-up in chest cavity lead to:*

Impairs Outcomes

The Enhanced Recovery After Surgery (ERAS) society is a multidisciplinary group committed to developing evidence-based initiatives and perioperative guidelines in order to reduce complications and speed patient recovery following surgery. Recent evidence-based guidelines for enhanced recovery after cardiac surgery were published in the Journal of the American Medical Association (JAMA) Surgery.


The guidelines offer multimodal recommendations across the entire perioperative period, with the maintenance of chest tube patency given the society’s strongest recommendation. Furthermore, they advised against chest tube stripping and breaking the sterile field of chest tubes to remove clots, methods that are frequently used in current practice.
