Multiple-channel imaging laparoscopy and uses thereof

An endoscopic device, comprising:

• an illumination channel;
• an imaging channel parallel to the illumination channel and having a different longitudinal axis from a longitudinal axis of the illumination channel;
• a laser diode at a proximal end of the illumination channel and offset from the longitudinal axis of the illumination channel and configured to emit a laser;
• at least one imaging sensor at a proximal end of the imaging channel and offset from the longitudinal axis of the imaging channel;
• a first pair of prisms between the laser diode and the proximal end of the illumination channel and configured to change a propagation direction of the laser;
• and
• a second pair of prisms between the proximal end of the imaging channel and the at least one imaging sensor and configured to change a propagation direction of light from the imaging channel,
• wherein the illumination channel is configured to transmit the laser from the laser diode to a distal end of the illumination channel, and
• wherein the imaging channel is configured to transmit light from a distal end of the imaging channel to the at least one imaging sensor.
