Vascular surgeon Bryan Tillman, MD, PhD, has developed a new type of surgical stent graft that could change how surgeons approach certain vascular procedures. The invention was first conceptualized during a discussion with his neighbor, organ transplant surgeon Amit Tevar, MD. Dr. Tillman illustrated the idea on a paper napkin while they talked in his family room.
Traditional surgical clamps have been used for decades to stop blood flow during operations. While these clamps are generally safe for use on the legs, Dr. Tillman notes that applying them to major arteries such as the aorta can lead to complications due to interrupted blood flow.
To address this issue, Dr. Tillman designed a retrievable rescue stent graft that eliminates the need for traditional clamps. The device is inserted through a catheter in a minimally invasive procedure and deployed inside the artery. This allows surgeons to repair vessels without stopping blood flow. After surgery, the stent can be removed as easily as it was placed.
Ohio State Health and Discovery supports efforts like Dr. Tillman's by promoting research and innovation in health care and education according to its official website. The organization operates hospitals and outpatient facilities as part of its academic medical center according to its official website. Its mission includes advancing health both locally and globally through research advances and community involvement according to its official website.
Dr. Tillman's work aligns with Ohio State Health and Discovery's broader goals of improving patient care and addressing societal issues related to health equity according to its official website.
