Founded in 2016 by Aaron Kaplan and Carol Devellian, Conformal Medical is a Nashua, New Hampshire-based company developing left atrial appendage occlusion technology to prevent strokes in patients with non-valvular atrial fibrillation. The pre-commercial organization is conducting a pivotal clinical trial enrolling approximately 1,600 patients to evaluate its proprietary CLAAS AcuFORM System, aiming to simplify procedures into same-day, single-operator interventions. Operating with fewer than 25 employees and generating under $5 million in revenue, the firm secured an $85 million Series C in 2020 and a $35 million Series D in 2023. Backed by investors including Fidelity Management and Catalyst Health Ventures, the developer is led by CEO James Reinstein and CFO Melissa Farina. The cardiovascular device manufacturer recently entered an acquisition agreement with WL Gore and Associates that is expected to close in early 2026.

Conformal Medical, Inc. is a privately held medical device company founded in 2016 and headquartered in Nashua, New Hampshire, specializing in stroke prevention for patients with non-valvular atrial fibrillation (AFib).[1][2][5] The company develops the CLAAS System, a left atrial appendage occlusion (LAAO) device that seals the left atrial appendage (LAA) to reduce stroke risk without requiring long-term anticoagulant therapy, serving patients and healthcare professionals seeking less invasive alternatives to current treatments.[1][2][3][5] It has raised $129M in total funding, including a $32M Series D extension in 2023, and is advancing through pivotal trials like CONFORM (over 420 patients randomized) and GLACE, with over 100 patients treated using the next-generation CLAAS AcuFORM System, demonstrating strong growth momentum toward FDA pre-market approval.[1][3]
Conformal Medical was founded in 2016 in Nashua, New Hampshire, as a medical device innovator targeting stroke prevention in AFib patients.[1][2] While specific founders are not detailed in available sources, the company emerged from the need for improved LAAO technologies, focusing on devices that conform to diverse patient anatomies to meet unmet clinical demands in atrial appendage closure.[1] Early traction built through development of the proprietary CLAAS System, featuring a foam-based architecture for broad LAA sealing with just two sizes, leading to pivotal moments like the 2023 $32M Series D extension to fund next-generation AcuFORM advancements and clinical trials.[3] Recognition as Powerhouse MedTech Company of the Year by the New England Venture Capital Association's 2023 NEVY Awards highlighted its evolution, with CEO James Reinstein emphasizing commitment to transforming procedures into same-day, single-operator interventions.[4]
Conformal Medical rides the explosive growth of the LAAO market, projected to expand from $1.5B in 2023 sales to $3B by 2027 and over $6B post-2030, driven by rising AFib prevalence (affecting millions globally) and demand for anticoagulant alternatives amid bleeding risks.[4] Timing aligns with maturing medtech innovation in minimally invasive cardiology, where procedural simplification addresses pain points like general anesthesia needs in current devices, potentially shifting clinical practice toward outpatient, operator-efficient interventions.[3][4] Favorable market forces include FDA trial pathways, investor support from Catalyst Health Ventures, Fidelity Investments, and Sprig Equity, plus NEVY recognition amplifying New England medtech ecosystem influence.[1][4] By pioneering ICE-guided LAAO, Conformal influences broader adoption of patient-centric devices, reducing healthcare burdens in an aging population with surging AFib epidemiology.[3][4]
Conformal Medical is poised for U.S. commercialization via CONFORM and GLACE trial completions, targeting FDA approval with a disruptive CLAAS AcuFORM System that could capture significant LAAO market share through procedural ease and broad applicability.[1][3] Upcoming milestones include full trial data readouts, potential CE Mark in Europe, and expanded enrollment, fueled by $129M raised and strong safety signals from 500+ implants.[1][3] Trends like AFib's 21st-century rise, minimally invasive tech mandates, and anticoagulant avoidance will propel growth, evolving Conformal's role from innovator to market leader in stroke prevention—redefining LAA closure as accessible and transformative, much like its anatomy-conforming origins promised.[4]
