Abstract:
An access device adapted for insertion into a body passage for removing debris from the body passage, the access device, comprising:an outer tube having a proximal tube end, a distal tube end, and a lumen extending between the proximal tube end and the distal tube end;an obturator assembly having a proximal obturator end and a distal obturator end, and being removably and concentrically disposed within the lumen of the outer tube;an expandable member having a proximal member end and a distal member end, the proximal member end being connected to the distal tube end, and the distal member end being coupled to the distal obturator end;the expandable member being expandable by relative movement between the proximal member end and the distal member end resulting from relative movement of the outer tube and the obturator assembly in opposite directions;the distal member end having properties for being decoupled from the distal obturator end to create an opening into the expandable member; andthe opening being sufficiently large to receive the debris from the body passage.
