Abstract

Disclosed is a balloon catheter () with a drug coating. The balloon catheter comprises a pushing catheter (), at least one expandable first balloon () located at a distal end of the pushing catheter (), and a pre-expansion mechanism. The first balloon () is fixedly arranged on the pushing catheter (). The pre-expansion mechanism () comprises an expansion sleeve () and a connector (). The expansion sleeve () is used for housing the first balloon () before the first balloon () is not expanded and when same is pre-expanded. The connector () is connected to the expansion sleeve () and axially moves with respect to the pushing catheter () after the first balloon () is pre-expanded, so that the first balloon () is exposed outside the expansion sleeve (). The balloon catheter () with a drug coating can effectively pre-expand a lesion location and can also effectively prevent the loss of a balloon with a drug coating during a delivery process, and is simple in terms of a surgical operation process.
