Abstract
A drug-eluting medical device and method for treating a chronic total occlusion. The drug-eluting medical device is implanted into the chronic total occlusion and elutes a drug that softens or dissolves the plaque of the occlusion over a period of time. After the medical device has resided in the occlusion for an appropriate period of time such that at least a portion of the chronic total occlusion has been softened or dissolved, a guidewire can cross the occlusion and a procedure such as PTCA can be performed.
Claims33
A method of treating a chronic total occlusion comprising the steps of:
- identifying a blood vessel with a chronic total occlusion;
- delivering a medical device adjacent to the chronic total occlusion;
- implanting the medical device into the chronic total occlusion;
- delivering a therapeutic formulation from the medical device to the chronic total occlusion over a sustained time period sufficient to dissolve or soften at least a portion of the chronic total occlusion.
A medical device comprising:
- an implant configured to be implanted into a chronic total occlusion;
- and
- a plaque softening or dissolving formulation contained in the implant, the implant being configured for administration of the formulation to the chronic total occlusion over a sustained time period sufficient to soften or dissolve at least a portion of the chronic total occlusion.
