Abstract

Seal assemblies are provided, comprising a seal holder including a cylindrical wall portion having a tapered distal portion, wherein the cylindrical wall portion defines a central passage. 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 the distal and/or proximal aperture is dimensioned for substantial sealed reception with a 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 substantially 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.
