PROBLEM TO BE SOLVED: To provide a surgical seal assembly for use with a surgical access device. SOLUTION: A surgical seal assembly is provided which comprises a seal holder including a cylindrical wall portion which defines a central passage which tolerates passage of the surgical instrument through the seal holder. The seal assembly comprises a ball seal supported in the central passage of the seal holder. The ball seal includes a distal aperture and a proximal aperture, wherein at least one of the distal and/or proximal aperture is dimensioned for substantial sealed reception with the surgical instrument. The ball seal is adapted for angular movement relative to a central longitudinal axis of the seal holder upon angulation of the surgical instrument, whereby the ball seal maintains the seal with the surgical instrument. The seal assembly comprises a seal cover defining an aperture formed in a transverse wall thereof. The seal cover is configured for connection with the seal holder for maintaining the ball seal within the central passage of the seal holder. COPYRIGHT: (C)2009,JPO&INPIT
