Balloon Catheter TRIZ Cases
- Balloon Coating via Core Member Rotation
Inserting a core member into the guide wire lumen prevents balloon deformation during clamping, enabling stable rotation for uniform drug coating application.
- Balloon Catheter Deformable Guidewire Shaft Steering
Inflation of an adjacent balloon deforms a guidewire shaft to orient the distal tip, resolving tortuous anatomy navigation challenges.
- Balloon Catheter Slidable Tube Merging Inflation Deflation
Slidable inner tube reciprocates within a catheter shaft to change tank pressure for balloon inflation and deflation.
