A fully automatic organ pressure sensitive apparatus for dislodging and removing obstructions in body cavities or organs by both delivering (17) and removing (20) fluid thereto, operable by high rate continuous or intermittent infusion of fluid solvent over a set pressure range to effect rapid dissolution and removal of the obstruction without complications to the patient. By continuous feedback monitoring (22) of fluid pressure in the bodily organ or cavity (19) of interest, the apparatus can constantly vary infusion and aspiration rates to maintain the set pressure range. If the pressure persists above or below the set range, the apparatus activates a safety feature (32) leading to a period of maximal aspiration and cessation of infusion, followed by cessation of solvent transfer and triggering of an alarm (34) to alert the operator. |
