Access devices and methods for treatment of medical conditions and delivery of injectables

An access device configured for guiding instruments to a region within a human body, the access device comprising:

• a shaft comprising a proximal end and a distal end, the shaft defining a lumen comprising channels extending longitudinally between the proximal end and the distal end, the channels comprising an instrument channel and a guide wire channel;
• a head attached to the distal end of the shaft, the head comprising a top surface, a bottom surface opposite the top surface, and a port configured to allow an instrument extended through the instrument channel to interact with the region of the human body;
• a hinged shell attached to the top surface of the head and configured to pivot toward and away from the top surface of the head;
• a guidewire opening in the hinged shell sized to receive a guide wire extending from the guide wire channel, the guide wire thereby holding the hinged shell in a closed position when the guidewire extends through the guidewire opening;
• and
• a camera mounted on an underside of the hinged shell between a distal end of the hinged shell and the port and commutatively coupled to a camera cable extending through the shaft, the camera oriented to capture images of the region of the human body.
