A blade having a sharp edge may be shiftable from a horizontal position to a vertical position so as to allow traveling thereof along the longitudinal channel. First stapling jaw portion may include a first row of tissue fasteners of a first staple size or/and type, and second stapling jaw portion may include a second row of tissue fasteners of a second staple size or/and type. Also described are methods for surgically fastening and cutting a bodily tissue or/and organ. ## Claims ### Claim 1 A tissue stapler head, comprising: a stapling jaw configured to include a first stapling jaw portion and a second stapling jaw portion being relatively positioned so as to be oppositely separated from each other by a longitudinal channel extending therebetween, said longitudinal channel is sized and configured for allowing a blade having a sharp edge to travel therealong; and an anvil jaw positionable to oppose said stapling jaw; wherein said first stapling jaw portion includes a first row of tissue fasteners of a first staple size or/and type adjacent to a first side of said longitudinal channel, and said second stapling jaw portion includes a second row of tissue fasteners of a second staple size or/and type adjacent to a second side of said longitudinal channel. ### Claim 2 (depends on 1) The tissue stapler head according to claim 1, wherein said tissue fasteners of said second size or/and type have staple legs that are plastically deformable to an inwardly bent form. ### Claim 3 (depends on 1) The tissue stapler head according to claim 1, wherein said tissue fasteners of said second size or/and type have a minimal leg length being greater than about 3 mm. ### Claim 4 (depends on 1) The tissue stapler head according to claim 1, wherein said tissue fasteners of said first size or/and type have a maximal leg length being less than about 3 mm. ### Claim 5 (depends on 1) The tissue stapler head according to claim 1, wherein at least one of said tissue fasteners of said first and second size or/and type includes at least one rigid or elastic prong. ### Claim 6 (depends on 1) The tissue stapler head according to claim 1, wherein said second stapling jaw portion has a plurality of rows of tissue fasteners including said second row of tissue fasteners of said second staple size or/and type. ### Claim 7 (depends on 1) The tissue stapler head according to claim 1, wherein said first stapling jaw portion includes suturing means. ### Claim 8 (depends on 1) The tissue stapler head according to claim 1, wherein said first stapling jaw portion includes tissue bonding means, tissue coagulating means, or tissue adhering means. ### Claim 9 (depends on 1) The tissue stapler head according to claim 1, wherein, in close proximity between said stapling jaw and said anvil jaw, said first stapling jaw portion faces a first contact surface of said anvil jaw and said second stapling jaw portion faces a second contact surface of said anvil jaw, wherein a first distance extending between said first stapling jaw portion and said first contact surface is less than a second distance extending between said second stapling jaw portion and said second contact surface. ### Claim 10 (depends on 9) The tissue stapler head according to claim 9, wherein said first contact surface and said second contact surface are distanced apart from each other by a contact surface transition portion located therebetween, said contact surface transition portion includes a rise such that said first contact surface is elevated relative to said second contact surface. ### Claim 11 (depends on 1) The tissue stapler head according to claim 1, configured and operative so as to be convertible from a delivery configuration including said stapler head in a non-operational mode and in which said stapler head is passable through a passage enclosing a minimal inner diameter, to a deployment configuration including said stapler head being in an operational mode. ### Claim 12 (depends on 11) The tissue stapler head according to claim 11, wherein, in said delivery configuration, said stapling jaw and said anvil jaw are consecutively arranged lengthwise relative to each other. ### Claim 13 (depends on 11) The tissue stapler head according to claim 11, wherein, in said delivery configuration, said stapler head has maximal cross-sectional dimensions including a maximal height, a maximal width, or/and a maximal diameter, each of said dimensions being smaller than said minimal inner diameter of said passage. ### Claim 14 (depends on 13) The tissue stapler head according to claim 13, wherein, in said delivery configuration, each of said maximal stapler head cross-sectional dimensions is equal to or less than about 8 mm. ### Claim at position 15 -41.
