Abstract
An expandable trocar includes a trocar body defining a hollow trocar stem having a cross-sectional inside area, and an outwardly projecting rib disposed on an outside surface of the trocar body. The trocar body is constructed to expand the cross-sectional inside area of the hollow trocar stem upon an application of an expanding force. The trocar body is formed of a resilient material such that when the expanding force is removed, the trocar body retracts the cross-sectional inside area.
