1. A powered endoscopic vessel harvesting (EVH) device, comprising:
a body including a cavity into which at least a first canister of a media is inserted;
a tapered tip disposed at a distal end of the body and in fluid communication with the first canister via a conduit in the body, the tapered tip having a design to facilitate advancement of the body to a site of interest and through which the media from the first canister can be directed to the site of interest through the conduit, wherein wiring for powering and/or communicating with electrical components within the EVH device extends through the conduit such that the wiring and the media share said conduit;
a control mechanism positioned on the body and including a coupling mechanism extending within the cavity such that, upon initial engagement of the first canister with the coupling mechanism: (a) the media can be released from the first canister into the conduit in the body and towards the tapered tip upon activation of the control mechanism; and (b) any remaining media can be contained within the first canister upon deactivation of the control mechanism; and
a dispersion mechanism coupled to the body and being variable for controlled release of a flow rate of the media out of the tapered tip.
