Abstract: A surgical stapling assembly is disclosed. The assembly can include a cartridge body having cavities defined therein forming a pattern of openings in the deck of the cartridge body. The pattern can include longitudinally-repeating clusters of cavity ends. The assembly can also include fasteners removably positioned in the cavities. The pattern of openings can comprise openings on a first side of the cartridge body comprising inner openings each defining an inner proximal-to-distal axis oriented parallel to the longitudinal axis, outer openings each defining an outer proximal-to-distal axis obliquely-oriented relative to the longitudinal axis at an outer angle, and intermediate openings each defining an intermediate proximal-to-distal axis obliquely-oriented relative to the longitudinal axis at an intermediate angle, wherein the intermediate angle is different than the outer angle.

Abstract: A musical drum 40 which utilizes a principle of physics to achieve an unequal tensioning of the upper head 20 and the lower head 36 without the need of physical attachments or piercing of the drum shell 24. The shell of the drum 24 remains suspended by shell's bearing edge 26, in contact only with the upper and lower heads 20 and 36 respectively. This allows the shell 24 of the drum to resonate freely and unencumbered by any attachments of hardware.
