PROBLEM TO BE SOLVED: To provide a surgical portal device having enhanced retention characteristics. SOLUTION: The surgical portal device includes a body portion dimensioned for insertion within a tissue tract. The body portion includes an outer wall defining a longitudinal axis and having a proximal end, a distal end, and a lumen configured to allow a surgical instrument to pass therethrough. A thread segment extends at least partially along the outer wall of the body portion. At least one of the outer wall and the thread segment has a textured surface. The textured surface may define irregularities. The irregularities are dimensioned to engage or receive tissue segments adjacent the tissue tract to thereby facilitate retention of the body portion relative thereto. COPYRIGHT: (C)2011,JPO&INPIT
