What ACI Medical does

ACI Medical, LLC is a privately held biomedical engineering firm founded in 1984 in Los Angeles and currently headquartered in San Marcos, California. The company develops, manufactures, and distributes non-invasive pneumatic compression technologies for patients with limb- and life-threatening vascular conditions, with its core therapeutic platform built around rapid sequential compression of the foot, ankle, and calf to increase arterial blood flow and promote collateral artery formation (arteriogenesis). Its flagship ArtAssist device — supported by the proprietary EndoShear technology with sub-300 millisecond compression cycles and an adaptive pressure function — is a prescription home-use device for peripheral arterial disease (PAD), critical limb ischemia (CLI), diabetic foot ulcers, intermittent claudication, and rest pain, backed by more than 65 peer-reviewed clinical studies. The portfolio also includes diagnostic and clinical workflow products (VenaPulse for vascular technologists, APG Air Plethysmograph for chronic venous disease quantification) and adjacent consumer-facing devices (FlowDyn for athletic recovery, UnnaSleeve for venous insufficiency compression).

ACI Medical generates revenue through three streams: direct hardware sales of its medical device portfolio, a subscription rental program for ArtAssist (typical 3-6 month duration), and contract manufacturing services spanning FDA-registered miniature diaphragm pumps and custom plastic injection molding for medical and industrial clients. The company sells direct-to-consumer through its website and toll-free contact channels (with a doctor's prescription required for ArtAssist) and maintains an exclusive distribution relationship with the VA Hospital system nationwide, supplemented by academic research partnerships with institutions including Mayo Clinic, Kaiser Permanente, Stony Brook, and the University of Manitoba. The company holds multiple U.S. patents (notably #4,936,758 and #5,017,100 on diaphragm pump designs), is FDA registered, ISO 13485 certified globally, and has had modified products deployed on the Mir Space Station and International Space Station for cardiovascular research — establishing credibility for its engineering and quality systems. ACI Medical operates from a single manufacturing facility in San Marcos, CA, with no disclosed institutional funding, parent company, or acquisition history.

Core offering

ACI Medical is a biomedical engineering firm that researches, develops, manufactures, and sells non-invasive pneumatic compression medical devices for vascular conditions, including the ArtAssist® device for peripheral arterial disease, the VenaPulse® device for venous insufficiency exams, the APG® Air Plethysmograph for chronic venous disease diagnostics, the FlowDyn™ athlete recovery device, and the UnnaSleeve™ compression sleeve. The company also provides contract manufacturing services for miniature diaphragm pumps and custom plastic molding.

Product overview

ACI Medical offers a portfolio of non-invasive vascular technologies consisting of therapeutic and diagnostic medical devices. The core therapeutic products include ArtAssist® (The Arterial Assist Device®), a prescription pneumatic compression device for PAD patients that triples arterial blood flow and promotes collateral artery growth, and FlowDyn™ for athletes seeking accelerated muscle recovery. Diagnostic products include the APG® Air Plethysmograph for quantifying chronic venous disease components and the VenaPulse® hands-free augmentation device for venous exams. The UnnaSleeve™ provides compression therapy for venous insufficiency. Additionally, ACI Medical offers contract manufacturing services including miniature diaphragm pumps and custom plastic molding.
