System and method for pressure monitoring within a catheter system

A catheter system for disrupting calcification at a treatment site within or adjacent to a vessel wall or heart valve, the catheter system comprising:

• a balloon that is positionable substantially adjacent to the treatment site, the balloon having a balloon wall that defines a balloon interior, the balloon interior being configured to receive a balloon fluid;
• an inflation conduit that is in fluid communication with the balloon interior, the inflation conduit being configured to convey the balloon fluid into the balloon interior;
• and
• a pressure sensor assembly that is configured to sense a balloon pressure of the balloon fluid within the balloon interior, the pressure sensor assembly being in fluid communication with the balloon interior and the inflation conduit.

A catheter system for disrupting calcification at a treatment site within or adjacent to a vessel wall or heart valve, the catheter system comprising:

• an energy source that generates energy;
• a balloon that is positionable substantially adjacent to the treatment site, the balloon having a balloon wall that defines a balloon interior, the balloon interior being configured to receive a balloon fluid;
• an energy guide that is configured to receive energy from the energy source, the energy guide guiding the energy into the balloon interior;
• a handle assembly that is coupled to the balloon, the handle assembly being positioned spaced apart from the balloon, the handle assembly being usable by a user to operate the catheter system;
• an inflation conduit that is in fluid communication with the balloon interior, the inflation conduit being coupled to the handle assembly, the inflation conduit being configured to convey the balloon fluid into the balloon interior;
• and
• a pressure sensor assembly that is configured to sense a balloon pressure of the balloon fluid within the balloon interior, the pressure sensor assembly being in fluid communication with the balloon interior and the inflation conduit, the pressure sensor assembly being positioned within the handle assembly.
