About balloon compliance in bifurcation techniques: Surprise!
Author: Gérard FINET, MD PhD, Hospices Civils de Lyon, Lyon – France
SUMMARY
What we think we know:
- The mechanical behavior of balloon is entirely elastic
- NO – balloon and polymer are elastoplastic (and viscoelastic)
- Reproducible from one inflation to another (iterative balloon inflation)
- NO – balloon elastoplas1city induces, amer each inflation, a systematic increase in the diameter of the balloon
- The curve provided by the manufacturer is accurate
- NO – balloon diameters are systematically below the theoretical curve of the manufacturer during the first inflation (deployment of the balloon)
- Modern balloons are equivalent from one manufacturer to another NO
