[0054] In some embodiments, the lengths of the first (9) and second (10) reinforcing members are correlated with preventing incidences of leak from the medical device disclosed herein when it is in a closed condition. For example, the probability of an incidence of leak is about 10% to about 25% less in a medical device where first (9) and second (10) reinforcing members are 80 mm long than in a medical device where the first (9) and second (10) reinforcing members are 50 mm long.

[0055] In some embodiments, the first reinforcing member 9 is about 2, 3, 4, 5, 6, 7, 8, 9, 10, 11,

12, 13, 14, 15, 16, 17, 18, 19, or 20 mm wide. In some embodiments, the first reinforcing member 9 is about 2-20 mm wide. In some embodiments, the first reinforcing member 9 is about 5-20 mm wide. In some embodiments, the first reinforcing member 9 is about 10-20 mm wide. In some embodiments, the second reinforcing member 10 is about 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12,

13, 14, 15, 16, 17, 18, 19, or 20 mm wide. In some embodiments, the second reinforcing member 10 is about 2-20 mm wide. In some embodiments, the second reinforcing member 10 is about 5-20 mm wide. In some embodiments, the second reinforcing member 10 is about 10-20 mm wide. In some embodiments, the first reinforcing member 9 and the second reinforcing member 10 are offset from each other, along the vertical axis 28, by about 1 mm to about 5 mm. In some embodiments, the widths of the first 9 and second 10 reinforcing members are dependent on the type of material used for the reinforcing members. In some embodiments, the widths of the first 9 and second 10 reinforcing members are proportional to their flexibility. In some embodiments, the first reinforcing member 9 and the second reinforcing member 10 are made of polystyrene and are about 20 mm wide. In some embodiments, the first reinforcing member 9 and the second reinforcing member 10 are made of polyethylene and are about 15 mm wide. In preferred embodiments, the first reinforcing member 9 and the second reinforcing member 10 are made of polystyrene.

[0056] Referring to Figs. 3 and 4, which illustrate a first embodiment of the medical device with an opening system, the first reinforcing member 9 and the second reinforcing member 10 have lateral edges 11. The lateral edges are deformable by application of pressure. Fig. 11 is a side- view of the outlet in use illustrating the application of pressure to the first reinforcing member 9 and the second reinforcing member 10, of the first embodiment, as the opening 8 is radially distended and opened for drainage. A user squeezes together the lateral edges of reinforcing member 9 and reinforcing 10 at the peripheral edge of the outlet 33. While reinforcing member 9 is placed away from edge of the opening 8 in this view, the reinforcing member may be at or near the opening edge 8, for example, at a distance of about 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 mm or more from the opening edge 8. In some embodiments, pressure may be applied to the lateral edges of the first reinforcing member 9 and the second reinforcing member 10 to push the edges from its flat un-deformed state to a curved deformed state inward towards the midline of the opening 8, thereby radially distending the opening 8. Such deformation is reversible when the pressure is removed. The first reinforcing member 9 and the second reinforcing member 10 may have corners that are notched, grooved, cut-to-shape or the like. In some embodiments, the first reinforcing member 9 and the second reinforcing member 10 may have corners that are square, rounded, flared, or have material removed, creating a void 12 (Figs. 3 and 4) to facilitate finger positioning by a user. The material can be removed from either a single lateral edge or from both lateral edges. In some embodiments, the shape of the first and second reinforcing members may enable easy handling of the medical device, for draining and closing. For example, a user may have his/her fingers fit the notched or voided region of the first and second reinforcing member, to open or close the outlet with ease. Further, users with poor dexterity may also benefit from the notched or voided design of the first and second reinforcing members. The reinforcing member may have corners that are grooved, cut-to-shape or the like to allow finger positioning by a user.

[0057] In some embodiments, the first reinforcing member 9 may be positioned above to the second reinforcing member 10 by a single lateral fold of the outlet. In some embodiments, the first reinforcing member 9 may be stacked on top of the second reinforcing member 10 and the first fastener 13 may be stacked on top of the first reinforcing member by two lateral folds of the outlet. In some embodiments, the first fastener 13 may form a linkage with the second fastener 17 by three lateral folds of the outlet, as seen in Fig. 9.
