Abstract
A balloon anchor provides for the anchoring of a surgical instrument, such as conventional trocar sheath, within a puncture opening formed by a trocar. When used on a trocar sheath, the anchor is secured to the smooth outer surface of the sheath for extension through the puncture opening as the trocar within the sheath forms the opening. Adhesive or mechanical means are provided to secure the balloon the instrument. No modification to the structure of the instrument is required. Once in place within the opening, the balloon is inflated to the interior of the tissue to anchor the instrument in place. Certain embodiments also provide for inflation of the balloon within and/or to the exterior of the opening.
