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.

Method and apparatus for anchoring laparoscopic instruments

A lifting apparatus for deployment through a laparoscopic incision in a body wall to apply an external lifting force over a large area of the body wall. The apparatus provides a broad lifting surface that is capable of applying a lifting force of at least 40 pounds (180 Newtons) to an area of a body wall sufficiently extensive to reduce the lifting pressure exerted on the body wall to well below that which could cause pressure trauma to the body wall, yet delivers this broad lifting surface through the body wall via an incision about 14 mm long. The apparatus comprises a body wall engaging element capable of passing in a packaged state through the laparoscopic incision, and being inflatable to an inflated state. In the inflated state, the body wall engaging element is substantially toroidal, provides a broad lifting face, and bounds a central hole. The body wall engaging element includes an equatorial portion facing into the central hole. The apparatus also includes a flexible lifting element that has a flexible portion capable of passing through the laparoscopic incision. The flexible portion is attached to the equatorial portion of the body wall engaging element and extends from the equatorial portion towards the broad lifting face. The flexible lifting element also includes an adapter, connected to part of the flexible portion remote from the equatorial portion of the body wall engaging element, that receives the external lifting force and transfers the external lifting force to the flexible portion.
