Technological Offers
Safe Injection Device for Endoscopic Treatment of Gastric Varices.
Description
Y-shaped three-way stopcock featuring two independent inlets and a single outlet connected to the catheter.
Check/non-return valves on each inlet channel preventing fluid backflow and cross-contamination between syringes.
Push-button locking mechanism with two positions (open/closed) for precise fluid flow control.
Medical need
Gastric varices secondary to portal hypertension carry a high risk of rupture and elevated mortality rates.
Current techniques require extremely rapid syringe swapping to flush cyanoacrylate with saline before polymerization.
Any delay during syringe exchange leads to irreversible catheter occlusion and potential fatal complications.
Results
- Functional prototype designed to ensure ergonomic dual-syringe operation simultaneously.
- Proof-of-concept validation for unidirectional flow and sealing integrity of the safety mechanism.
Prevalence
20% of patients with portal hypertension, with a rebleeding risk and mortality of up to 45%
Market
Global GI endoscopy and hemostasis devices market: > $ 5 billion with continued growth
Other solutions
Conventional direct injection systems: clack non-return valves, require manual synringe disconnection,, high occlusion risk.
