Aquedeon Medical: A NewGeneration of Cardiothoracic Graft Anastomoses
Tom Palermo, Co-Founder
When a patient is diagnosed with a life-threatening tearingof the aorta’s layers, the immediate course of action is emergency surgery. To access the effected anatomy,this open surgery requires what is calledhypothermic circulatory arrest (HCA).HCA is a standard of care in which very cold body temperaturescan be used for up to 40 minutes to limit cerebral metabolism, thus providing neuroprotection for the patient. Under HCA, thesurgeon has a limited timeframe to identify the damage and to surgically reconstructthe aorta and effected blood vessels. To create a reliable path for blood flow, portions of the damaged aorta and vessels are replaced with synthetic graft(s) offered from a variety of manufacturers.The overall surgery lasts around four to six hours, and within that time there exists an upper limit to the required HCA to safeguard against brain damage. Therefore, these procedures are complex and high-pressure. According to Grayson Wheatley, MD of TriStar Medical Group in Nashville, TN, “We as surgeons must work quickly to determine the location of the tears, choose the most appropriate approach, and get the patient into the OR. A matter of minutes can save lives.”
Aquedeon Medical’s mission is to reduce the underlying HCA time associated with reconstruction of the aorta and effected blood vessels. After only three years since its inception, Aquedeon Medical has demonstrated strong progress in the development of a very intriguing technology. The company’s Duett Vascular Graft System is designed as a modular solution to rapidly connect a patient’s native vessel to a synthetic one.According to Bilal Shafi, MD of Sutter Health in Santa Cruz, CA, “Using an anastomoses device that connects a surgical graft to an artery could reduce the risk associated with HCA time, potentially protecting the brain from injury.”
A matter of minutes can save lives
Aquedeon Medical’s team of medical professionalsmaintain a comprehensive understanding of the importance and significance of creating technologies that drive consistency. Wilson Szeto, MD of Penn Medicine in Philadelphia, PA stated, “Any time we (surgeons) can make something more reproducible, we hope the conduct of operation and ultimately the outcomes can have less variation and be improved.” The elegance of Aquedeon Medical’s solution is that it does not change the surgical procedure, instead it augments the surgeon’s processes related to connecting vessels to grafts (anastomoses). Faraz Kerendi, MD of Cardiothoracic and Vascular Surgery in Austin, TX stated, “An anastomoses device that can adapt to the variations of the patient’s vasculature and surgeon’s technique preferences is beneficial”.
“Our device performs like a self-expanding connector, which helps connect the patients’ vessels to syntheticbranch grafts,typically in four minutes or less per vessel,” statedTom Palermo, co-founder and COO of Aquedeon Medical. The company’s Duett Vascular Graft System enables suture-less anastomoses - the system consists of a specialized Delivery System and a preloaded self-expanding Duett Vascular Graft. The DeliverySystem has a dual action slider. The first activation of the slider deploys the Duett Vascular Graft within the patient’s native vessel.The second deployment of the slider completes the anastomosis to the required graft.
Aquedeon Medical works through strong collaborations with renowned cardiothoracic surgeons, solving problems they routinely encounter. After recently exiting stealth mode, Aquedeon Medical looks to continue moving forward with its technology development. “There is an opportunity to enhance surgery by reducing HCA time associated with aortic reconstruction”, stated Timothy Buckley Vice President of Marketing. He continued, “if our technology can help a surgeon save even one extra life, it will all be worthwhile.”
