Zusammenfassung:An angioplasty balloon (40) is provided with a plurality of scoring elements (44) extending along the balloon (40). Within the scoring element (44) there are provided channels or lumens (36) extending therethrough. The channels or lumens (36) provide for Rayleigh scattering of ultrasonic waves directed to the balloon (40), thereby being visible by imaging devices. The channels or lumens (36) provide visibility of the balloon (40) during medical procedures, both when the balloon (40) is in a deflated, wrapped, condition and also when the balloon (40) is inflated. It is not necessary to use contrast media to fill the balloon (40).
