Abstract
Abdominal wall lift devices and methods are disclosed that extend a lift device through an opening in the abdominal wall in an entry configuration and subsequently transform the device to a deployed configuration within the abdominal cavity. One embodiment includes a plurality of elongated bar members that may be introduced into an abdominal cavity in a separated end-to-end orientation. The bar members are subsequently interconnected into a deployed configuration within the abdominal cavity. Another embodiment includes a device that may be introduced through a small opening in an abdominal wall in a generally L-shaped configuration and subsequently deployed into a generally T-shaped configuration within the abdominal cavity. A further embodiment includes an umbrella-like device that may be introduced in a slender generally cylindrical configuration and subsequently deployed into an open umbrella-type configuration.
