Extended spectral sensitivity endoscope system and method of using the same

A method, comprising:

• illuminating at least a portion of a ureter at a first wavelength;
• illuminating the portion of the ureter at a second wavelength different than the first wavelength;
• and
• based on the illuminating at the first wavelength and the illuminating at the second wavelength, identifying a composition of a kidney stone within the ureter.

A method, comprising:

• inserting an endoscope at least partially into a ureter;
• illuminating at least a portion of the ureter at a first wavelength;
• illuminating the portion of the ureter at a second wavelength different than the first wavelength;
• comparing an image of the ureter when illuminated at the first wavelength to an image of the ureter when illuminated at the second wavelength;
• and
• selecting a medical device or a treatment parameter for a medical device to treat an area of interest within the ureter based on the comparing.

A method comprising:

• illuminating at least a portion of a body lumen at a first wavelength;
• illuminating the portion of the body lumen at a second wavelength different than the first wavelength;
• imaging the portion of the body lumen when illuminated at the first wavelength and illuminated at the second wavelength;
• producing a first image of the portion of the body lumen based on the first wavelength;
• and
• producing a second image of the portion of the body lumen based on the second wavelength.

A method, comprising:

• inserting an endoscope at least partially into a body lumen;
• illuminating at least a portion of the body lumen at a wavelength;
• producing a first image of the portion of the body lumen when illuminated at the wavelength;
• after the producing, injecting into the body lumen via a lumen of the endoscope at least one of a fluid or colloid filter agent such that the at least fluid or colloid filter agent a body portion within the body lumen;
• after the injecting, producing a second image of the portion of the body lumen when illuminated at the wavelength;
• identifying a characteristic of the body portion based on a difference between the first image and the second image.

A processor-readable medium storing code representing instructions to cause a processor to perform a process, the code comprising code to:

• receive a first signal associated with a first image from an endoscope;
• identify a characteristic associated with an area of interest within the first image;
• receive a second signal associated with a second image from the endoscope;
• identify a change in the characteristic associated with the area of interest within the second image.
