Dr. Douglas Gesner is a board-certified, fellowship-trained interventional radiologist and healthcare executive with nearly two decades of experience in high-acuity, image-guided therapies across both hospital and outpatient settings. As Chief Medical Officer of CyndRX, he leads the clinical strategy, physician engagement, and medical positioning of the company’s flagship vascular closure technology, AbsorbaSeal.
Throughout his clinical career, Dr. Gesner practiced in a high-volume private practice environment, where he performed complex arterial and venous interventions, with a particular focus on limb salvage procedures. His extensive experience with vascular access and closure—often in anticoagulated patients—has provided him with a deep understanding of the limitations of traditional closure technologies, including bleeding complications, access site pain, and delayed patient recovery. This firsthand insight directly informs his leadership in advancing next-generation solutions designed to improve both clinical outcomes and procedural efficiency.
At CyndRX, Dr. Gesner plays a central role in shaping the clinical value proposition of AbsorbaSeal, a fully bioabsorbable vascular closure device designed to provide secure, mechanical hemostasis independent of anticoagulation status. Under his medical leadership, the company is focused on redefining the standard of care in vascular closure by enabling reliable hemostasis, reducing complications, and supporting earlier patient ambulation and discharge—critical factors in today’s high-volume procedural environment.
