Abstract:
1. A device for treatment of a chronic total occlusion, the device comprising: a catheter having a proximal end and a distal end; a detachable tip having a proximal end and a distal end, wherein the proximal end of the tip is attached to the distal end of the catheter such that the tip extends distally therefrom while the catheter is being advanced to the chronic total occlusion, the tip being formed of a biodegradable polymer with an active agent dispersed therethrough, the active agent being effective to degrade or soften at least a portion of the chronic total occlusion; and a detachment mechanism for detaching the tip from attachment with the distal end of the catheter, the detachment mechanism is a hooked distal end of the tip for lodging within the chronic total occlusion and holding the tip therein while the catheter is withdrawn thereby permitting the attachment between the tip and the distal end of the catheter to be broken.
