Accumulation of fluid is a normal consequence of cardiac surgeries such as Bentall surgery, valvular replacement, coronary artery bypass graft procedure and aortic surgical procedures. To remove this fluid, drainage catheters are usually inserted, post-op, in the pericardial space for a period of up to five days. The current drainage catheters are stiff/rigid, painful, impede on patient mobility. Moreover, they need to be changed frequently during the post-op period. Also, even with these catheters, the accumulation of fluid can result into compression of the venus return, leading to cardiac tamponade, a severe even fatal complication. The prevalence of this tamponade ranges from 5-7%. The catheter developed by Pr. Garon and Dr. Carrier proposes to reduce the prevalence of tamponade. Its design has been optimized to improve the drainage. It is composed of three collector heads which offer a full drainage of the heart surrounding area from a single external tube. Finally, the catheter is built from soft materials thus minimizing the patient discomfort, reducing the need to change the catheters, and improving the patient mobility. By addressing the main shortcomings of other drainage catheters, higher volume drainage is aimed at reducing the tamponade incidence to low and acceptable levels.

液体积聚是心脏手术的正常结果，例如Bentall手术、瓣膜手术、 冠状动脉旁路移植手术和主动脉外科手术。为了移除这些液体， 引流导管通常在手术后插入心包腔中长达五天的时间。的 目前的引流导管是硬的/刚性的、疼痛的、妨碍患者活动的。此外，他们需要 在术后期间经常变化。此外，即使使用这些导管，液体的积聚也可能 导致静脉回流受压，导致心包填塞，这是一种严重甚至致命的并发症。 这种填塞的患病率范围为5- 7%。 Garon教授和Carrier博士开发的导管旨在降低填塞的发生率。其 优化设计以改善排水。它由三个收集器头组成， 从一根外部导管对心脏周围区域进行引流。最后，导管由柔软的 材料，从而最大限度地减少患者的不适，减少更换导管的需要，并改善患者的活动性。通过解决其他引流导管的主要缺点，更高容量的引流旨在将填塞发生率降低到较低和可接受的水平。
