Abstract
There is presented an interventional device (100), such as a device for minimally invasive surgery, comprising a bag arranged for being transformable between an open configuration and a closed configuration, a shaft (106), a grasper (108) mounted on a distal end of said shaft, wherein the bag further comprises a fluid passageway arranged so that in the closed configuration the fluid passageway enables that fluid may be expelled through the fluid passageway from an interior volume of the bag to an exterior volume of the bag and furthermore enables that a solid element above a predetermined threshold size may be retained in the bag. The fluid passageway may be advantageous for enabling that liquid may be expelled from the bag while larger solid elements, such as a piece of a tumour, may be retained in the bag for removal from a body cavity.
