Patent ID: 7887504

Claim:
An apparatus, comprising: an elongate body including a proximal end portion and a distal end portion, said elongate body configured to be at least partially inserted into a body cavity, said elongate body defining a first passageway and a plurality of second passageways, each of said plurality of second passageways in fluid communication with one of a plurality of elongate cut-out sections, each of said elongate cut-out sections having a length greater than a width defined in part by a side-wall of said elongate body, each of said elongate cut-out sections extending in a direction parallel to a centerline of the elongate body and being disposed circumferentially around said first passageway, wherein each of said plurality of elongate cut-out sections is equally spaced from the centerline of said first passageway at a distal-most end of the first passageway, and having a cross-section that extends through a distal-most end of said elongate body, said first passageway configured to communicate fluid from said distal end portion in a first direction, said plurality of second passageways configured to communicate material from outside of said plurality of elongate cut-out sections of said elongate body into said distal end portion in a second direction opposite the first direction, the first passageway having a length extending from a proximal-most end to a distal-most end of the first passageway, wherein the first passageway is fluidly isolated from each of said plurality of second passageways along said length of said first passageway; and an actuator coupled to said elongate body, said actuator configured to guide said distal end portion of said elongate body to an area of interest pre-identified by a virtual colonoscopy.
