Guide Needles TRIZ Cases

See how piezoelectric and strain gauge sensors detect catheter shaft deflection in real time, i

A protective sleeve with a depth gauge and adjustable magnetizer segments enables consistent needle magnetization without contamination or tip damage.

A deformable metal guide tube retains its bent shape to guide instruments through complex body lumens and stabilize access to treatment sites.

A telescoping anti-buckling tube stabilizes robotic catheter and guidewire delivery, reducing motion through long, tortuous neurovascular anatomy.

A shape-memory metal guide tube bends to match complex body lumens, then holds its form to guide instruments closer to treatment targets.

A dual retraction spring layout cuts inserter height while enabling perpendicular catheter placement and automatic introducer needle shielding.

Dual retraction springs in parallel barrels enable perpendicular catheter insertion with automatic needle withdrawal in a compact insulin infusion inserter.

Real-time sensor feedback lets an AI catheter tune sheath oscillation to remove large, hard clots faster with lower bleeding risk.

A synced user device handles PIN entry and transaction selection, cutting skimmer exposure and ATM keypad wear.

A mobile device handles PIN entry and transaction selection, cutting skimming risk while reducing ATM interface wear and component count.

A curved needle-catheter geometry aligns axially with the vein to prevent wall diving, reduce trauma, and improve blood draw and infusion success.

A telescoping tube with inner-diameter reduction shortens unsupported catheter length to limit buckling during deep neurovascular advancement.

Flexible interfaces and spacers at catheter and luer adapters reduce extension tubing kinks and maintain consistent fluid flow.

A sliding hollow-body septum improves catheter placement confirmation by controlling blood flow through sealed openings for clearer flashback.
