Penumbra, Inc. is an Alameda, California medical device company that builds tools to pull life-threatening blood clots out of the body. Founded in 2004 by attorney-turned-CEO Adam Elsesser and neuro-interventional surgeon Dr. Arani Bose, it pioneered aspiration-based mechanical thrombectomy for acute ischemic stroke and expanded into peripheral, venous, and pulmonary clot removal with its Indigo and Lightning Flash systems. The company also runs an Immersive Healthcare arm using virtual reality (the REAL System) for rehabilitation and wellness. Public on the NYSE since 2015 under ticker PEN, Penumbra posted $1.4 billion in 2025 revenue and agreed in January 2026 to be acquired by Boston Scientific in a roughly $14.5 billion deal.
David Stoffel is the Chief Business Officer of RapidAI, the clinical-AI company whose stroke-imaging algorithms helped rewrite the rules of how strokes get treated. A medical doctor who chose boardrooms over bedsides, he has spent more than two decades turning ambitious medical technologies into standards of care - from the da Vinci surgical robot at Intuitive Surgical to mobile cardiac telemetry at iRhythm and point-of-care EEG at Ceribell. At RapidAI he runs the commercial engine: marketing, clinical affairs, education, customer success, corporate development, and finance.
Nventric, Inc. is a medical device company and contract development and manufacturing organization (CDMO) headquartered in Arcadia, California, with operations in Seoul, South Korea. Founded in 2019 by engineers with backgrounds at Abbott Vascular and Johnson & Johnson, Nventric designs and builds minimally invasive vascular devices - covering neurovascular, coronary, and electrophysiology applications - from concept through scalable, ISO 13485-certified manufacturing. Its own-branded neurovascular line, including the ULTRIVA stent retriever and EVOGLIDE distal access catheter, targets acute ischemic stroke, while its OEM/CDMO services help device companies move products from prototype to commercialization.

A former Panamanian ambassador to the UAE and Saudi Arabia turned investor and operator, he joined the XCath board in 2019 and took the helm in 2023, also serving as interim CEO of sister company EndoQuest Robotics. Under his leadership XCath has logged a string of world firsts, including the first public remote mechanical thrombectomy demonstration and, in 2026, the world's first remote robotic intervention in a stroke patient.

Sungwoo Min is the founder and CEO of Nventric, Inc., an Arcadia, California medical device company that designs, develops, and contract-manufactures vascular devices for the neurovascular, electrophysiology, and coronary markets. A Stanford-trained mechanical engineer who cut his teeth on R&D and marketing at Abbott Vascular and later led R&D programs at Johnson & Johnson, he started Nventric in 2019 to build the kind of life-saving catheters, stents, and thrombectomy systems he used to ship at the giants - this time end to end, ISO 13485 certified, with operations in the US and South Korea. He is a named inventor on multiple US patents for mechanical thrombectomy devices.
