Imaging apparatus and method which utilizes multidirectional field of view endoscopy

An apparatus for coupling to a probe having a proximal end and a distal end and a long axis therebetween and providing information regarding at least one structure, comprising:

• a light source which is configured to forward multiple radiations at different respective switchable wavelengths to at least one portion of the at least one structure,
• the multiple radiations being provided as multiple bands of radiation to provide differential contrast for tissue imaging;
• an electronics arrangement comprising a photodetector which is configured to obtain the information and transmit the information wirelessly to provide images in real time,
• the photodetector comprising an image sensor which is configured to detect image information regarding the at least one portion based on the wavelengths,
• the image sensor being arranged to detect the image information in a direction perpendicular to the long axis of the apparatus;
• a portable power arrangement comprising a battery disposed adjacent to the probe, at least a portion of the battery and at least a portion of the photodetector being intersected by a plane that is perpendicular to the long axis, the battery being configured to provide power to at least one component of the electronics arrangement;
• and
• a structural connection configuration comprising a cap which is structured and configured to be attached to the probe,
• the cap including an inner tube surface comprising a polymeric material to frictionally engage the probe.
