An expandable element isolation assembly can comprise an expandable element, and at least one rigid support element that is located external to the expandable element and is positionable between at least part of the expandable element and an inner wall of a formation at an open-hole portion of a wellbore in response to expansion of the expandable element. The at least one rigid support element can reinforce the expanded expandable element, such as through physical contact therewith. A retraction mechanism may be provided to retract the at least one rigid support element upon contraction of the expandable element.
