The sleeve comprises a first sleeve portion, a second sleeve portion, a plurality of flanges, and a reversible locking mechanism. The second sleeve portion is disposed around the first sleeve portion and is reversibly slidable distally from a first position to a second position along the first sleeve portion. The plurality of flanges is disposed in a radial sequence around the first sleeve portion. The flanges are radially collapsed along the first sleeve portion when the second sleeve portion is in the first position and are radially expanded when the second sleeve portion is in the second position. The first sleeve portion is configured for placement of a surgical port therethrough and to be fixedly secured to the surgical port therealong. Additional sleeves are also disclosed. ## Claims ### Claim 1 A sleeve for retention of a surgical port comprising: (a) a first sleeve portion comprising a proximal end, a distal end, and a first sleeve portion body extending therebetween; (b) a second sleeve portion comprising a proximal end, a distal end, and a second sleeve portion body extending therebetween, the second sleeve portion being disposed around the first sleeve portion and being reversibly slidable distally from a first position to a second position along the first sleeve portion; (c) a plurality of flanges disposed in a radial sequence around the first sleeve portion adjacent the distal end of the first sleeve portion, each flange having a proximal end, a distal end, and a flange strip extending therebetween, the proximal end of each flange extending from the distal end of the second sleeve portion in the radial sequence, the distal end of each flange extending from the distal end of the first sleeve portion in the radial sequence, and the flanges being radially collapsed along the first sleeve portion when the second sleeve portion is in the first position and being radially expanded around the first sleeve portion when the second sleeve portion is in the second position; and (d) a reversible locking mechanism that can be reversibly actuated to prevent the second sleeve portion from sliding along the first sleeve portion when the second sleeve portion is in the second position, wherein: the first sleeve portion body has an outer surface, an inner surface, a proximal opening, a distal opening, and a lumen extending between the proximal and distal openings of the first sleeve portion body; the second sleeve portion body has an outer surface, an inner surface, a proximal opening, a distal opening, and a lumen extending between the proximal and distal openings of the second sleeve portion body; the inner surface of the second sleeve portion body is in slidable contact with the outer surface of the first sleeve portion body; the first sleeve portion is configured for placement of a surgical port through the proximal opening of the first sleeve portion body and into the lumen of the first sleeve portion body to the distal opening of the first sleeve portion body and to be fixedly secured to the surgical port along the inner surface of the first sleeve portion body; and the distal end of the first sleeve portion does not extend distally beyond the distal ends of the flanges when the second sleeve portion is in the first position or the second position. ### Claim 2 (depends on 1) The sleeve according to claim 1, wherein the second sleeve portion is configured for placement of the first sleeve portion within the lumen of the second sleeve portion body through the proximal opening of the second sleeve portion body. ### Claim 3 (depends on 1) The sleeve according to claim 1, wherein the plurality of flanges consists of 5 to 25 flanges. ### Claim 4 (depends on 1) The sleeve according to claim 1, wherein each flange has a radial length of 1 to 15 mm when radially expanded around the first sleeve portion. ### Claim 5 (depends on 1) The sleeve according to claim 1, wherein each flange is integral to the first and second sleeve portions. ### Claim 6 (depends on 1) The sleeve according to claim 1, wherein each flange is attached to the first and second sleeve portions. ### Claim 7 (depends on 1) The sleeve according to claim 1, wherein each flange has a sigmoidal shape. ### Claim 8 (depends on 1) The sleeve according to claim 1, wherein each flange has an intermediate portion between the proximal and distal ends of the flange and a width that decreases distally from the proximal end of the flange to the intermediate portion and that increases distally from the intermediate portion to the distal end of the flange. ### Claim 9 (depends on 1) The sleeve according to claim 1, wherein the first sleeve portion, the second sleeve portion, and the plurality of flanges are made from one or more of polyethylene terephthalate glycol, polycarbonate, or polystyrene. ### Claim 10 (depends on 1) The sleeve according to claim 1, further comprising a flexible film covering the second sleeve portion and the plurality of flanges, the flexible film being adhered to the first sleeve portion at the distal end of the first sleeve portion and to the second sleeve portion along the outer surface of the second sleeve portion body, and the flexible film not being adhered to the plurality of flanges. ### Claim 11 (depends on 1) A system for retention of a surgical port comprising: (a) the sleeve according to claim 1; and (b) a surgical port, wherein: the first sleeve portion is fixedly secured to the surgical port along the inner surface of the first sleeve portion body. ### Claim 12 (depends on 1) A method of use of the sleeve of according to claim 1 in performing a surgery on a patient in need thereof, the method comprising steps of: (1) securing the sleeve to a surgical port fixedly along the inner surface of the first sleeve portion body; (2) inserting the surgical port and the sleeve through an incision in a body wall of the patient such that the flanges of the sleeve extend into a surgical cavity of the patient, wherein during the inserting the second sleeve portion is in the first position and the flanges are radially collapsed along the first sleeve portion; (3) sliding the second sleeve portion from the first position to the second position, thereby radially expanding the flanges around the first sleeve portion; (4) actuating the reversible locking mechanism to prevent the second sleeve portion from sliding along the first sleeve portion; and (5) inserting one or more surgical instruments through the surgical port into the surgical cavity of the patient. ### Claim 13 (depends on 12) The method according to claim 12, the method further comprising steps of: (6) withdrawing the one or more surgical instruments from the surgical cavity of the patient through the surgical port; (7) releasing the reversible locking mechanism to allow the second sleeve portion to slide along the first sleeve portion; (8) sliding the second sleeve portion from the second position to the first position, thereby radially collapsing the flanges along the first sleeve portion; and (9) withdrawing the surgical port and the sleeve from the surgical cavity through the incision in the body wall.
