Methods for treating vascular stenoses including laser atherectomy and drug delivery via drug-coated balloons

A method for treating a stenosis includes providing a laser ablation system including a laser catheter, the laser catheter including a distal end having a plurality of laser emitters; positioning the distal end of the laser catheter within the subject proximate the target vascular portion; deliverin...

Beschreibung
Zusammenfassung:	A method for treating a stenosis includes providing a laser ablation system including a laser catheter, the laser catheter including a distal end having a plurality of laser emitters; positioning the distal end of the laser catheter within the subject proximate the target vascular portion; delivering laser energy to the laser catheter and emitting the laser energy from the plurality of laser emitters to ablate the stenosis; withdrawing the laser catheter from the subject; providing a balloon system including a drug-coated balloon, the balloon carrying at least one therapeutic agent, the therapeutic agent being a restenosis inhibitor; positioning the balloon within the subject proximate the target vascular portion; expanding the balloon to engage the target vascular portion; delivering the therapeutic agent from the balloon to the target vascular portion; delivering the therapeutic agent from the balloon to the target vascular portion; and withdrawing the balloon from the subject.
