Guide Wires TRIZ Cases
- X-ray Diagnosis Apparatus Catheter Tip Direction Guidance
Processing circuitry extracts characteristic sites from medical image data to determine catheter tip end direction along the insertion path.
- Surgical Guide Wire Tool Segmented Jaw Mechanism
Segmented jaw mechanism engages guide wire via spring-loaded biasing, resolving complexity trade-offs in surgical tool operation.
- Segmented Guidewire with Nitinol Core and Stainless Steel Sheath
Segmented design exposes the nitinol core at the distal end for kink resistance while retaining the stainless steel sheath proximally to improve pushability.
- Open-cell clot capture device for stroke reperfusion
An open-cell capturing member engages emboli without fragmenting them, preventing vessel dissection and hemorrhage while restoring blood flow.
- Variable Stiffness Fiber Optic Guidewire for Vascular Lesion Crossing
Fiber optic guidewire transmits laser energy through a variable stiffness hypotube to ablate vascular obstructions.
- Segmented Medical Guidewire Resilient Tip Design
A segmented guidewire combines a stainless steel core with a superelastic Nitinol tip to enhance pushability and flexibility.
- Micro-cutting Machine for Polymer Catheters
Dual-blade micro-cutting machine uses optical feedback to cut non-conductive plastic stock, resolving precision limits of single-blade systems.
- Electrosurgical Probe Integrating Microwave Coagulation and Liquid Dispensing
A coaxial electrosurgical probe delivers microwave energy for tissue coagulation while dispensing liquid medicine through a hollow inner conductor.
- Tapered Catheter with Localized Structural Support for Kinking Resistance
A tapered catheter body uses a composite structural support member to maintain navigability through tortuous vasculature.
- Motorized Guidewire Manipulation Device for Torque Control
A motorized guidewire manipulation device uses a tandem roller assembly to drive rotation and provide consistent traction.
- Catheter Control Mechanism for Precise Bend Angle Adjustment
A catheter control mechanism converts rotational motion into precise linear actuation to adjust the distal tip curvature.
- Reversible Intraluminal Member for Vascular Ablation
Reversing the intraluminal member direction prevents vein entanglement and optimizes sclerosant delivery precision.
- Catheter Light Source Positioning for Opening Identification
Embedded light sources enable visual identification of catheter opening positions through external photography.
