Guide Wires TRIZ Cases
- Bendable Guidewire With Nested Oblique Slits
Nested oblique slits distribute bending stress to prevent cracking in flexible guidewires navigating cerebral arteries.
- Catheter Hub Sealed Access Port Design
A catheter hub integrates a sealing element within an aperture to enable rapid medical device access through the fluid passageway.
- Segmented Guidewire Minimizing Annular Space and Whip
Segmented guidewires minimize annular space with catheters while maintaining flexibility, reducing radial offset and procedural complications.
- MRI Composite Fiber Guidewire with Integrated Sensor
Pultruded composite shaft enables sensor integration in MRI guidewires without RF-heating or imaging artifacts.
- Wire Feeding Device with Dynamic Grip and Elastic Biasing
A wire feeding device uses a dynamic grip mechanism to advance medical wires through occlusions.
- Slit Dilator With Slidable Sleeve For Tissue Protection
A dilator tube with a longitudinal slit and slidable sleeve closes the opening during insertion to maintain structural integrity.
