AI Technical Summary
Balloon catheters with multilayer structures face issues where rupture in a layer with lower strength can lead to excessive dilation beyond the appropriate diameter due to uneven stress distribution, compromising the pressure resistance.
A catheter balloon with a multilayer structure where the first and second layers have the same rupture strength, with the second layer covering the first and having different material properties to control dilation, ensuring balanced stress distribution and preventing excessive dilation.
The balanced multilayer structure enhances pressure resistance and prevents excessive dilation by evenly distributing stress across layers, maintaining desired physical properties and dilation control.
