Abstract: An example filtration device may include a plurality of filter lobes. The filtration device may also include a spine connected to each of the plurality of filter lobes such that each filter lobe is interconnected through the spine. Each of the plurality of filter lobes may be positioned at an angle with respect to a longitudinal axis of the spine such that each of the plurality of filter lobes are parallel to one another. The filtration device may also include a terminal lobe including a surface positioned substantially parallel to the longitudinal axis of the spine. The filtration device may also include a plurality of pores positioned at a distal end of each of the plurality of filter lobes, and a waste channel in fluid communication with each of the plurality of pores.

Abstract: A suction device having the ability to adhere to rough surfaces is provided, along with methods for attaching the suction device to a target surface. The suction device includes a body having a suction area and a plurality of micro-rods depending from margins of the suction area. The micro-rods provide sufficient friction when placed against a target surface that a suction seal can be formed by generating negative pressure between the suction area and the target surface. In certain embodiments, the suction device provides suction even on wet or underwater surfaces.
