摘要：
A dynamic balloon angioplasty system for applying a dynamic pressure to fracture hardened materials embedded within an elastic conduit. The system having a pressure source system outputting at least a first predetermined pressure from a pressure source outlet, and an angioplasty unit fluidly coupled to the pressure source outlet receiving at least the first predetermined pressure. The angioplasty unit having an angioplasty inflation device, an angioplasty balloon connector, and an oscillating mechanism selectively actuated to output a plurality of pressure pulses to the angioplasty balloon via a fluid communication path. A control system is configured to determine an optimal hydraulic pressure oscillation frequency and amplitude for a given procedure and output a control signal to the oscillating mechanism, and monitor a pressure signal to detect fracture of the hardened material within the elastic conduit or system failure or leakage.
