Controller to select optical channel parameters in a catheter

A system, comprising:

• a microprocessor executable controller configured, based on one or more of total fiber active area of a laser catheter, imaging information regarding the target and/or non-target endovascular structure(s), target endovascular structure characterization information, current location and/or orientation of a distal tip of the laser catheter, and area of contact of the distal tip with the target and/or non-target endovascular structure to select at least one of a fiber active area for each optical channel, a number of optical channels, a configuration of fibers in an optical channel, an optical channel to be irradiated, and an ordering of optical channel irradiation.

A tangible, non-transient computer readable medium comprising microprocessor executable instructions that, when executed, perform operations comprising:

• selecting, based on one or more of total fiber active area of a laser catheter, imaging information regarding the target and/or non-target endovascular structure(s), target endovascular structure characterization information, current location and/or orientation of a distal tip of the laser catheter, and area of contact of the distal tip with the target and/or non-target endovascular structure at least one of a fiber active area for each optical channel, a number of optical channels, a configuration of fibers in an optical channel, an optical channel to be irradiated, and an ordering of optical channel irradiation.
