摘要

a drug-coated (dcb) balloon catheter (4) comprising a connector (8), an axis (20) extending from a proximal end (24) to a distal end (28) along an axial direction (xx) and having a guide wire lumen (32) and an inflation lumen (36) , the shaft (20) being connected to the connector (8) at said proximal end (24) and provided with an inflatable balloon (48), fluidly bonded to said inflation lumen (36) for the purpose of being selectively inflated and / or deflated. advantageously, the balloon (48) is conical and symmetrical in the axis about a prevalent extension axis (ss), wherein the balloon (48) has an increasing diameter (60) moving from a first end (52) to a second end (56), said diameter (60) being measured in a section plane perpendicular to said prevalent extension axis (ss), wherein an outer surface (64) of the balloon (48) is coated with a drug for the treatment of restenosis.
