Abstract:
1. A scope comprising: a module having at least an image sensor; an elongated stylet comprising a first end and a second distal end and an outer layer and having at least one centrally positioned inner lumen therein, a first end of the stylet proximate to the module, the elongated stylet having at least one pathway exterior to the at least one centrally positioned inner lumen; the at least one centrally positioned inner lumen further comprising a concentric arrangement comprising at least one fiber for receiving images; a lens located proximate to a distal end of the at least one fiber for receiving images; at least one outlet for each of the at least one pathway proximate to the second end of the elongated stylet to at least partially direct gas or fluid from the at least one pathway; at least one side fluid port formed in the outer layer of the elongated stylet and in fluid communication with at least one pathway; at least one branch pathway in communication with the at least one pathway, each of the at least one branch pathways oriented tangentially to the longitudinal axis of the elongated stylet to direct a gas or fluid from the at least one pathway through the outer layer of the elongated stylet; wherein the direction of the gas or fluid exiting the elongated stylet is substantially parallel to the direction the at least one branch pathway is oriented.
