Sleeve for retention of a surgical port comprising flanges that are reversibly radially expandable

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.
