SUPERHEATING SYSTEM FOR INERTIAL IMPULSE GENERATION TO DISRUPT VASCULAR LESIONS

摘要: A catheter system (100) for imparting pressure to induce fractures in a vascular lesion (808) within or adjacent vessel wall (806), includes (101 ) and superheating system. The (101) can advance the (808). an elongate shaft (102) balloon (122) coupled (102).
