PRESSURE INDUCED COLOR CHANGE FOR BALLOON CATHETER CHASSIS

A balloon catheter has a visual indicator to indicate when a maximum pressure has been reached or exceeded for forensic purposes after a catheter has failed. The visual indicator can be mechanical, such as a physical member that stretches or discolors upon yielding. Or the visual indicator can be th...

Zusammenfassung:	A balloon catheter has a visual indicator to indicate when a maximum pressure has been reached or exceeded for forensic purposes after a catheter has failed. The visual indicator can be mechanical, such as a physical member that stretches or discolors upon yielding. Or the visual indicator can be the use of a force sensitive polymer that changes color upon a predetermined stress, such as for example mechanophores. Where such visual indicators are present, a failed catheter can be investigated to determine if the failure was likely the result of overpressurization, or if the catheter failed for defects unrelated to the pressure.
