Every minute before surgery decides a life.
PRESSA is building the next generation of prehospital trauma technology — starting with one of medicine's hardest problems: severe internal bleeding.
- Injury
- Bleeding
- No effective prehospital intervention
- Surgery
- Too late
PRESSA exists to change the space between bleeding and surgery.
Solved
External bleeding
Tourniquets transformed survival from limb hemorrhage. Simple, fast, teachable.
Unsolved
Internal bleeding
It remains one of trauma's hardest unsolved challenges — with no equivalent field intervention before the operating room.
Why PRESSA
Clinical-first
Designed around what trauma teams actually do under pressure.
Engineering-first
Hardware, control, and safety built in-house, tested honestly.
Military insight
Field experience shapes the constraints — weight, speed, failure modes.
Build in public
We publish what works and what does not.
Designed with responders
Paramedics, surgeons, and medics in the loop from day one.
Long-term platform
One problem solved well, on architecture that extends.
Traction
Validation
Every claim we make has to survive clinical review. We run a structured discovery program with trauma surgeons, paramedics, and military medics — recorded, transcribed, and turned into design requirements.
Roadmap
The plan,
in public.
Every phase. Every milestone. Updated as we go.

Founder
Solly Marks
Three-time founder. Eight years in IDF armored corps, where the constraint was never medical knowledge — it was hands, time, and attention under load. That is the exact constraint PRESSA is engineered around: one responder, seconds to act, no second chances.

Become one of the first people following the development of what we hope becomes a new generation of trauma technology. Clinicians, responders, engineers, investors, potential partners — if you want to be part of this, we want to hear from you.
Technical questions
Straight answers.
Why a reusable controller?
Because the intelligence — pump, battery, processor, pressure logic — doesn't need to be thrown away after every use. Keeping it outside the body and out of the disposable makes the system cheaper, safer, and more serviceable.
Why a disposable head?
The only part that enters the wound is the balloon. Making it single-use lets us keep it sterile, simple, and free of electronics.
Why not keep electronics inside the body?
Electronics inside a wound add cost, risk, and disposal complexity. Our architecture keeps every sensor and every circuit outside the patient.
How does the pressure monitoring concept work?
A separate, patient-worn monitor reads pressure through an external access point on the sealed valve and streams it wirelessly to the controller. Concept only — subject to change during engineering.
Why a wireless monitor?
So the responder can walk away from one patient and still watch the pressure — the whole point of the system.
What happens if pressure changes?
The monitor alerts on the device and on the controller. Human judgment always stays in the loop.
Is PRESSA a cleared medical device?
No. PRESSA is a concept under development. Any future indications for use will depend on testing and regulatory review.
