Abstract
A vacuum device (10) has a collapsible cover (18) capable of maintaining a seal with a flexible surface (64) such as human tissue. A set of shaping members (20) support the cover (18) against collapse into the evacuated region in the interior, yet readily flex to maintain the seal with the deforming tissue without the need for an excessive sealing force.
