Balloon Catheter TRIZ Cases
- Modified Prosthetic Heart Valve Stent for Conduction Protection
A modified stent region limits radial expansion beside the cardiac conduction system while preserving anchoring around the aortic annulus.
- Endoscopic Balloon Treatment Tool With Ridge-Suppressing Thick Portion
Fluid introduced through the sheath expands the balloon for dilation, while localized wall thickening suppresses ridges that obstruct observation.
