The bag device may also include an indicator including at least one repeating pattern on a wall of the bag. The pattern may extend across at least one side of the bag. ## Claims ### Claim 1 An artificial pneumoperitoneum device, comprising: a bag, including: a membrane, an open end, a closed end, a body between the open end and the closed end, wherein the membrane at least partially defines the open end, the closed end, and the body, and dye formed on or in the membrane and arranged in a series of lines, wherein the series of lines includes a first set of lines and a second set of lines, the first set of lines extending across the second set of lines. ### Claim 2 (depends on 1) The artificial pneumoperitoneum device of claim 1, wherein the lines of the first set are perpendicular to the lines of the second set. ### Claim 3 (depends on 1) The artificial pneumoperitoneum device of claim 1, wherein the lines of the first set have the same thickness as the lines of the second set. ### Claim 4 (depends on 1) The artificial pneumoperitoneum device of claim 1, wherein each of the lines of the first set has a first thickness, each of the lines of the second set has a second thickness, and the first thickness is different than the second thickness. ### Claim 5 (depends on 1) The artificial pneumoperitoneum device of claim 1, wherein the lines of the first set run parallel to each other. ### Claim 6 (depends on 5) The artificial pneumoperitoneum device of claim 5, wherein the first set of lines includes a first subset of lines and a second subset of lines, lines of the first subset have a first thickness, lines of the second subset have a second thickness, and the first thickness is different than the second thickness. ### Claim 7 (depends on 6) The artificial pneumoperitoneum device of claim 6, wherein the lines of the first subset alternate with the lines of the second subset. ### Claim 8 (depends on 1) The artificial pneumoperitoneum device of claim 1, wherein the bag further includes a central longitudinal axis, and the lines of the first set extend longitudinally. ### Claim 9 An artificial pneumoperitoneum device, comprising: a bag, including: a membrane, an open end, a closed end, a body between the open end and the closed end, wherein the membrane at least partially defines the open end, the closed end, and the body, and dye formed on or in the membrane and arranged in a series of intersecting lines. ### Claim 10 (depends on 9) The artificial pneumoperitoneum device of claim 9, wherein the intersecting lines include a first set of lines and a second set of lines, and the lines of the first set are perpendicular to the lines of the second set. ### Claim 11 (depends on 9) The artificial pneumoperitoneum device of claim 9, wherein the intersecting lines include a first set of lines running perpendicular to the open end. ### Claim 12 (depends on 9) The artificial pneumoperitoneum device of claim 9, wherein the intersecting lines include a first set of lines and a second set of lines, and the lines of the first set have the same thickness as the lines of the second set. ### Claim 13 (depends on 9) The artificial pneumoperitoneum device of claim 9, wherein the intersecting lines include a first set of lines and a second set of lines, the lines of the first set have a first thickness, the lines of the second set have a second thickness, and the first thickness is different than the second thickness. ### Claim 14 (depends on 9) The artificial pneumoperitoneum device of claim 9, wherein the intersecting lines include a first plurality of parallel lines, and a second plurality of parallel lines, with parallel lines of the first plurality intersecting parallel lines of the second plurality. ### Claim 15 An artificial pneumoperitoneum device, comprising: a bag, including: a membrane, an open end, a closed end, a body between the open end and the closed end, wherein the membrane at least partially defines the open end, the closed end, and the body, and dye formed on or in the membrane and arranged in a grid on or in the membrane. ### Claim 16 (depends on 15) The artificial pneumoperitoneum device of claim 15, wherein the grid includes lines surrounding four-sided cells. ### Claim 17 (depends on 15) The artificial pneumoperitoneum device of claim 15, wherein the grid includes a first set of lines extending lengthwise along the bag, and a second set of lines extending widthwise along the bag. ### Claim 18 (depends on 17) The artificial pneumoperitoneum device of claim 17, wherein lines of the first set are perpendicular to lines of the second set. ### Claim 19 (depends on 15) The artificial pneumoperitoneum device of claim 15, wherein a first portion of the grid is on or in an anterior wall of the membrane, and a second portion of the grid is on or in a posterior wall of the membrane. ### Claim 20 (depends on 15) The artificial pneumoperitoneum device of claim 15, wherein the grid includes a first set of lines and a second set of lines, and the lines of the first set have a different thickness than lines of the second set.
