Abstract
As may be implemented in accordance with one or more embodiments characterized herein, aspects of the present disclosure are directed to an apparatus including first and second filters, a shaft and a frame coupled to the shaft and to the first filter. The frame and shaft operate to seal a perimeter of the first filter around an opening in a sidewall of a tubular structure, by pressing the frame against the perimeter and the sidewall. The second filter is also coupled to the frame and operates with the frame to extend into cross section of the tubular structure away from the frame and the sidewall, with the frame sealing the first filter around the opening, and to filter particles from fluid flowing past the opening and along the length of the sidewall.
