Abstract
An expandable port for minimally invasive surgery includes a first section, a second section, and at least one intermediate section. The port is expandable from a closed configuration in which the first section is proximate the second section along at least a portion of a length of the first section to an expanded configuration in which the first section is spaced apart from the second section. The intermediate portion spans a gap between the first section and the second section when the port is in the expanded configuration.
