Multi-Lumen Catheter TRIZ Cases
- Dual-Chamber Endoscopic Sheath for Complete Agent Delivery
Distal pistons in a dual-chamber sheath release and mix agents near the target site, reducing working-channel retention and waste.
- Splayed Microcannula Infusion for Single-Trajectory Putamen Delivery
Multiple splayed microcannulas deliver drug across the putamen through one trajectory, reducing repeat insertions, surgery time, and tissue trauma.
