Abstract
A catheter is disclosed that has a detachable tip for delivery of a therapeutic substance to a chronic total occlusion (CTO) within a body vessel. The tip is made from a biodegradable material and includes an active agent dispersed therethrough. The detachable tip pierces into the calcified lesion, detaches from the catheter, and remains embedded within the lesion as the tip degrades, thereby releasing the active agent. The active agent is a therapeutic substance effective to treat of a CTO. The active agent may be a drug, an enzyme, bacteria, or a parasite that degrades or softens the calcified lesion.
