Isa Rizk, CEO and co-founder of Reflow Medical, joins Life of Flow to share how he and his team built one of the most talked-about vascular device companies, without following the usual playbook.
In this episode, Isa walks us through the evolution of Reflow Medical, from its earliest days to the development of the Spur stent: a mechanical innovation designed for tibial disease. He breaks down what led them to shift from a single-product mindset to building a full-scale company, why reimbursement planning is just as important as engineering, and what it’s like to scale a team while staying independent.
🎧 Tune in for a transparent conversation about innovation, growth, and long-term thinking in the world of vascular technology.
