Abstract
An apparatus and method for guided penetration of a chronic total occlusion in a blood vessel are disclosed. The invention is directed to an apparatus that facilitates accurate placement of a drilling tip within a body lumen using ultrasound-based detection to determine the position of the intravascular catheter relative to the vessel occlusion and vessel walls.

26. An intravascular catheter system for penetration and imaging of an occlusion, comprising:
-
a therapeutic tip; a first vibration transducer connected to said therapeutic tip, said first vibration transducer capable of vibrating said tip at a first frequency sufficient to penetrate an occlusion, said occlusion located in a vessel having walls; a second vibration transducer, capable of generating a detectable signal at a second frequency, said second frequency different than said first frequency and transmitted simultaneously therewith, wherein said detectable signal may be processed into an image of at least one of said tip, occlusion and vessel walls, to enable said tip to be positioned relative to said occlusion and said vessel walls; and a power source, said power source being capable of energizing said first and second vibration transducers. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54)
