Abstract
A balloon catheter and balloon system particularly useful with drug-coated balloons is described. In some embodiments, the balloon catheter system includes various features designed to address problems with drug rubbing off due to contract friction during delivery of the balloon—including by utilizing a protective sleeve to shield the drug-coated balloon. In some embodiments, the balloon catheter system includes an inner high-pressure balloon and an outer drug-coated balloon to mitigate the time associated with performing vessel dilation.

(canceled)
A protective sleeve for a medical device, comprising:
- a distal tubular portion;
- and,
- a proximal body portion comprising an arc-shaped channel that connects at a proximal opening of the distal tubular portion.
A balloon catheter system comprising:
- a balloon catheter comprising a catheter body and a drug-coated balloon disposed at a distal end of the catheter body;
- and,
- a protective sleeve comprising:
- a distal tubular portion sized to accept the drug-coated balloon in a deflated state;
- and,
- a proximal body portion comprising an arc-shaped channel that connects at a proximal opening of the distal tubular portion;
- wherein the arc-shaped channel is shaped to accommodate at least a portion of a catheter body.
A protective sleeve for a medical device, comprising:
- a distal tubular portion means for accepting the drug-coated balloon in a deflated state;
- and,
- a proximal body portion comprising an arc-shaped channel means for accommodating at least a portion of a body of the balloon catheter and that connects at a proximal opening of the distal tubular portion.
