|
1. A catheter system for treating a treatment site within or adjacent to a blood vessel within a body of a patient, the treatment site having a proximal region and a distal region, the catheter system comprising:
an energy source that generates energy, the energy source being configured to generate a plasma, causing rapid bubble formation that imparts pressure waves upon the treatment site;
a guide shaft that is positionable adjacent to the treatment site;
a catheter shaft that is configured to be selectively positioned near the treatment site, the guide shaft being positioned at least partially within the catheter shaft;
an inflatable balloon that is coupled to the catheter shaft, the inflatable balloon including a balloon wall that defines a balloon interior, the inflatable balloon being configured to retain a balloon fluid within the balloon interior; and
an energy guide that receives energy from the energy source, the energy guide being movably coupled to the guide shaft, the energy guide including a guide distal end that is configured to be positioned within the balloon interior and adjacent to the treatment site, the guide distal end of the energy guide being selectively movable relative to the balloon and the guide shaft and adjacent to and between the proximal region and the distal region of the treatment site while the energy guide receives energy from the energy source, the energy guide guiding the energy from the energy source so that the plasma generation is initiated in the balloon fluid within the balloon interior, the guide distal end of the energy guide being in fluid communication with the balloon fluid in which the plasma is generated.

15. A catheter system for treating a treatment site within or adjacent to a blood vessel within a body of a patient, the treatment site having a proximal region and a distal region, the catheter system comprising:
an energy source that generates energy, the energy source being configured to generate a plasma, causing rapid bubble formation that imparts pressure waves upon the treatment site;
a guide shaft that is positionable adjacent to the treatment site, the guide shaft including a guidewire lumen that encircles a guidewire;
a catheter shaft that is configured to be selectively positioned near the treatment site, the guide shaft being positioned at least partially within the catheter shaft;
an inflatable balloon that is coupled to the catheter shaft, the inflatable balloon including a balloon wall that defines a balloon interior, the inflatable balloon being configured to retain a balloon fluid within the balloon interior;
an energy guide that receives energy from the energy source, the energy guide being movably coupled to the guide shaft, the energy guide including a guide distal end that is configured to be positioned within the balloon interior and adjacent to the treatment site, the guide distal end of the energy guide being selectively movable relative to the balloon and the guide shaft and adjacent to and between the proximal region and the distal region of the treatment site while the energy guide receives energy from the energy source, the energy guide guiding the energy from the energy source so that the plasma generation is initiated in the balloon fluid within the balloon interior, the guide distal end of the energy guide being in fluid communication with the balloon fluid in which the plasma is generated; and
an energy guide mover that selectively moves the energy guide so that the guide distal end of the energy guide moves adjacent to and between the proximal region and the distal region of the treatment site while the energy guide receives energy from the energy source.

22. A catheter system for treating a treatment site within or adjacent to a blood vessel within a body of a patient, the treatment site having a proximal region and a distal region, the catheter system comprising:
an energy source that generates energy, the energy source being configured to generate a plasma, causing rapid bubble formation that imparts pressure waves upon the treatment site;
a guide shaft that is positionable adjacent to the treatment site, the guide shaft including a guidewire lumen that encircles a guidewire;
a catheter shaft that is configured to be selectively positioned near the treatment site, the guide shaft being positioned at least partially within the catheter shaft;
an inflatable balloon that is coupled to the catheter shaft, the inflatable balloon including a balloon wall that defines a balloon interior, the inflatable balloon being configured to retain a balloon fluid within the balloon interior;
an energy guide that receives energy from the energy source, the energy guide being movably coupled to the guide shaft, the energy guide including a guide distal end that is configured to be positioned within the balloon interior and adjacent to the treatment site, the guide distal end of the energy guide being selectively movable relative to the balloon and the guide shaft and adjacent to and between the proximal region and the distal region of the treatment site while the energy guide receives energy from the energy source, the energy guide guiding the energy from the energy source so that the plasma generation is initiated in the balloon fluid within the balloon interior, the guide distal end of the energy guide being in fluid communication with the balloon fluid in which the plasma is generated; and
an energy guide mover that selectively moves the energy guide so that the guide distal end of the energy guide moves adjacent to and between the proximal region and the distal region of the treatment site while the energy guide receives energy from the energy source, the energy guide mover including a plurality of motorized rollers that engage the energy guide, the motorized rollers selectively moving the energy guide adjacent to and between the proximal region and the distal region of the treatment site while the energy guide receives energy from the energy source.
