1. A method of clearing obstructions from a medical tube, comprising coupling a guide tube in fluid communication with a medical tube thereby defining a common passageway through the respective tubes comprising a sterile field, wherein an elongate guide member is entirely disposed within said common passageway, and actuating said guide member without compromising the sterile field to correspondingly actuate a clearance member attached to or formed with said guide member in said medical tube, wherein said clearance member presents a substantially unobstructed pathway for the flow of material from a location in said medical tube distal to said clearance member to a location in said medical tube proximal to said clearance member regardless whether said clearance member is being actuated or is at rest within said medical tube.
