Pulsatile balloon catheter systems and methods of using the same

A pulsatile balloon catheter system, the system comprising:

• (a) a pulse generator configured to output energy to fracture calcified lesions, the pulse generator comprising:
• (i) a controller configured to control one or more of frequency, duty cycle and amplitude of the outputted energy from the pulse generator;
• (ii) an electrical connector electrically for connecting the controller to an electrical assembly of a balloon catheter assembly, wherein the electrical connector can be releasably coupled to an electrical connector of the balloon catheter assembly;
• (iii) a pneumatic connector configured to transmit energy from the pulse generator to a proximal port of the balloon catheter assembly, wherein the pneumatic connector can be releasably coupled to the proximal port of the balloon catheter assembly;
• and
• (iv) a release button configured to release the pulse generator from the balloon catheter assembly such that the electrical connector and the pneumatic connector can be disconnected from the balloon catheter assembly;
• (b) a balloon catheter assembly removably coupled to the pulse generator, the balloon catheter assembly comprising:
• (i) a proximal connector operably connected to the pulse generator, wherein the proximal connector comprises a proximal chamber and a distal chamber separated by a membrane and a proximal port configured to receive the outputted energy from the pulse generator, wherein the pulse generator is directly coupled to the proximal chamber through the proximal port, and the proximal port is releasably coupled to the pneumatic connector of the pulse generator;
• (ii) a catheter operably connected to the proximal connector and comprising a distal balloon;
• and
• (iii) an electrical assembly attached to the proximal connector and comprising memory,
• wherein the electrical assembly comprises a flexible printed circuit board disposed along an outer region of the proximal connector;
• the electrical assembly further comprises an electrical connector releasably coupled to the electrical connector of the pulse generator and electrically connecting the electrical assembly to the controller of the pulse generator;
• and
• the memory comprises configuration data for the catheter and the distal balloon.
