How SEAL Works in Seconds

Chitosan is a naturally derived biopolymer proven to accelerate clot formation. Unlike clotting that relies on the body’s natural cascade, SEAL works independently, making it effective even when clotting is impaired by medications, hypothermia, or severe injury.

Backed by Rigorous Testing and Clinical Research

SEAL is supported by multiple independent and in-house studies, including:

Study / Testing	Summary	Outcome
Femoral Arterial Bleed Model (compared to Celox)	Half dosed with heparin to impair clotting	SEAL achieved rapid, sustained hemorrhage control in all cases
Full-Thickness Burn Study	Investigating SEAL’s ability to treat burn wounds	Study completion Aug 2025, 510(k) planned
Environmental Testing	High/low temperature and altitude per STR-MIL-810H standards	Passed without degradation or loss of performance
Implantation Study (Planned)	Assessing SEAL’s ability to remain in wounds >30 days	In development
Surgical Collaboration – Duke University	Legal review underway for surgical use cases	Pending clinical initiation

Why SEAL is Different

Stops Life-Threatening Bleeding Fast: Proven to control bleeding in seconds, even in severe arterial injuries.

Works When Clotting is Impaired: Effective for patients on blood thinners or with compromised clotting function.

Proven in Extreme Conditions: Tested for use in high heat, freezing cold, and at altitude.

Compact & Simple: Lightweight aerosol can, no mixing, no complicated steps.

Trusted Globally: In use by military, law enforcement, EMS, and humanitarian aid organizations worldwide.

Trusted Where It Matters Most

SEAL is trusted by professionals and prepared civilians alike, from medics treating trauma in the field to parents managing accidents at home. Whether it’s a high-speed crash or a kitchen injury, SEAL stops bleeding fast when every second counts.

The Bigger Picture

There has been no meaningful innovation in severe bleed control in over 20 years. SEAL is a disruptive medical technology that challenges ingrained thinking in trauma care. Changing protocols, training, and regulations takes time, especially within government and large institutions. But SEAL is leading the way, alongside one other major innovator in this space.

Get SEAL. Save Lives.

Whether for professional, personal, or organizational use, SEAL is a critical tool for anyone who may face a bleeding emergency.
