Evident Vascular, Inc.
Evident Vascular is a San Jose-based medical device startup building an AI-powered intravascular ultrasound (IVUS) platform designed for peripheral vascular interventions. Founded in 2023 and led by CEO Howard Rosen, the company aims to fix the long-standing trade-off between image quality and clinical workflow that has limited IVUS adoption, targeting FDA 510(k) clearance ahead of a U.S. launch. It raised a $35M Series A from Vensana Capital and closed an undisclosed Series B in 2025.
Inquis Medical, Inc.
Inquis Medical is a Silicon Valley medical device company founded in 2020 by serial medtech entrepreneurs Vahid and Mojgan Saadat. Its flagship AVENTUS Precision Thrombectomy System removes blood clots from patients with pulmonary embolism (PE) and deep vein thrombosis (DVT), using proprietary TrueClot tissue-sensing technology that gives physicians real-time feedback to distinguish blood, clot, and vessel wall while minimizing blood loss through autologous blood reinfusion. Backed by $115M in total funding including a $75M Series C in January 2026, the company is scaling nationwide commercial adoption after winning FDA 510(k) clearance for PE in 2025.
Illuminant Surgical
Illuminant Surgical is a Culver City / Los Angeles medical device startup building Skylight, a real-time anatomical projection system that displays a patient's internal imaging directly onto their skin during surgery. Using AI, computer vision and dynamic projection mapping - technology borrowed in part from entertainment-industry projection artists - the company aims to give surgeons a kind of 'x-ray vision' for spine surgery, cancer biopsies and other image-guided procedures without forcing them to look away from the operating field.
Penumbra, Inc.
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.
MediView XR, Inc.
MediView XR is a Cleveland, Ohio med-tech company building augmented-reality 'X-ray vision' for surgeons. Founded in 2017 on Cleveland Clinic intellectual property, MediView's FDA-cleared XR90 platform and OmnifyXR Interventional Suite let clinicians see a patient's 3D anatomy - bone, tissue, organs, and vasculature - holographically projected through the skin during minimally invasive, ultrasound-guided procedures. Backed by GE HealthCare, Mayo Clinic, and Cleveland Clinic, the company raised a $24M Series A in October 2025.
Promaxo
Promaxo builds the world's first single-sided, in-office MRI platform - a compact magnet, AI, and robotics stack that lets urologists run image-guided prostate biopsies and focal treatments in their own clinic, without a hospital scanner suite.
