What medical devices, inc. does

Medical Devices, Inc. (MDI) is a privately held Michigan-based medical device manufacturer founded in 1982, headquartered in Romulus, MI. For its first two decades the company sold general medical consumables across the United States; during the Gulf War era it pivoted to tactical medical products and in 2009 launched the original Halo Chest Seal, the foundation of its current HALO product line. MDI designs, develops, and manufactures chest seals and vents used to prevent and treat tension pneumothorax in penetrating chest trauma, with documented deployments by U.S. and allied military, municipal law enforcement, fire departments, and EMS providers.

MDI's core technology centers on the HALO Vent, a transparent, vented chest seal with a one-way laminar valve designed to open at low "cracking" pressure to evacuate trapped air, blood, and fluids from the chest cavity during exhalation, reducing respiratory workload on hypoxic or fatigued patients. The products use a proprietary dual-adhesive system combining an outer tape edge with a custom hydrogel formulation effective in damp, dry, sandy, and hairy conditions and across a temperature range of -30°F to 140°F (-34°C to 60°C). HALO Vents feature four vents arranged around the dressing for orientation-agnostic drainage. The technology is protected by U.S. patent RE48,007 and the company holds ISO 13485:2016 quality certification plus EC Certification (renewed November 2024) for EU market access. Products are offered in US, EU, and UK regional variants and in IFAK (5.5" x 7.5") and Flat Pack (7.5" x 10.875") configurations.

MDI generates revenue through direct hardware sales of HALO Vent, HALO Seal, HALO XL, HALO Combo, and HALO Trainer products via its e-commerce website, phone ((800) 828-4681), email, and contact form, with no public list pricing (third-party sources reference IFAK pricing near $45). Distribution is direct-to-customer and through wholesale channels such as Amchar Wholesale at industry events; in the EU, Obelis s.a. serves as the Authorized Representative. The company is privately held with no disclosed investors, funding rounds, or parent company, and no management team, headcount, or revenue figures are publicly disclosed.

Emerging players

• Adventure Medical Kits: Adventure Medical Kits (a Safecross brand) produces consumer and outdoor first aid kits that increasingly include trauma care components. Represents the civilian and outdoor segment MDI is targeting, with overlapping use cases for hunters, hikers, and remote-area enthusiasts.

Direct peers

• Tactical Medical Solutions: Tactical Medical Solutions develops tactical medical kits and trauma products for military, law enforcement, and EMS markets directly comparable to MDI's HALO product line. Overlapping customer base and product category make it a close direct peer.
• Combat Medical Systems: Combat Medical Systems is a tactical medical equipment manufacturer producing chest seals, hemostatic dressings, and IFAK components for military and law enforcement. Directly competes with MDI in the chest seal and trauma kit categories.
• North American Rescue: North American Rescue (NAR) is the leading US manufacturer of tactical combat casualty care equipment, best known for the HyFin Vent Chest Seal, the primary direct competitor to HALO Vent. Both companies serve military, law enforcement, and EMS customers with similar single-use trauma products.
• SAM Medical Products: SAM Medical Products designs and manufactures trauma medical devices including chest seals, tourniquets, and splints. Competes directly with MDI in the chest seal and pre-hospital trauma care product categories.
• H&H Medical: H&H Medical manufactures chest seals and tactical medical products under the Bolin and H&H brands, including the H&H PriMed Chest Seal. Direct competitor in the same chest seal category with overlapping military and first responder customer base.

Others

Broad incumbents

• Stryker: Stryker is a major medical device conglomerate with significant emergency and trauma product lines. While not a pure-play chest seal competitor, it competes indirectly for hospital and EMS trauma budgets and represents the type of broad incumbent MDI faces in procurement.
• ZOLL Medical: ZOLL Medical (acquired by Asahi Kasei) provides resuscitation and emergency medical equipment including products for trauma and EMS applications. A broad incumbent in the emergency medicine space that competes for the same first-responder procurement budgets as MDI.
• Teleflex: Teleflex is a large global medical device company with a tactical and emergency medicine portfolio that overlaps with MDI's chest seal category. As a broad incumbent, it offers trauma and airway products alongside much larger hospital and surgical lines.
