Fluorophore imaging devices, systems, and methods for an endoscopic procedure

A fluorophore imaging system, comprising:

• an endoscope comprising an imaging device that faces from a side of the endoscope at a location along a length of the endoscope and that comprises a sensor that is configured to detect light in the visible spectrum, or light in the near infrared spectrum, or both;
• and
• an attachment removably couplable to a distal end of the endoscope including a first filter alignable with a light source of the endoscope, and a second filter alignable with the imaging device of the endoscope;
• wherein the attachment comprises an extension portion configured to extend distally of a distal end of the endoscope;
• and wherein the attachment is coupled to the distal end of the endoscope such that a working channel of the endoscope is accessible when the attachment is coupled to the endoscope;
• wherein the first filter is a light source bandpass filter that is configured to block emitted light in the visible spectrum, or in the near infrared spectrum, or both;
• wherein the second filter is a sensor bandpass filter that is configured to block detected light in the visible spectrum, or in the near infrared spectrum, or both;
• and
• wherein the attachment includes a first portion and a second portion, the first and second portions being lockable with each other to rotationally fix the attachment to the distal end of the endoscope.

• wherein the attachment comprises an extension portion configured to extend adjacent to an exposed side facing working channel of the endoscope, such that the working channel is accessible when the attachment is coupled to the endoscope wherein the first filter is a light source bandpass filter that is configured to block emitted light in the visible spectrum, or in the near infrared spectrum, or both;
• wherein the second filter is a sensor bandpass filter that is configured to block detected light in the visible spectrum, or in the near infrared spectrum, or both;
