A pleural effusion treatment apparatus for delivery of adhesive material comprising two components adapted to adhere pleural membranes (12, 14) defining a pleural space, the apparatus comprising: a pleural space access member adapted to deliver the adhesive material to the pleural space, wherein the pleural space access member comprises: an adhesive material delivery device comprising a syringe (141, 142, 143, 144, 145) and a mixing element adapted to mix the two components prior to injection of the adhesive material into a patient; and a catheter and a spreading element adapted to percutaneously deliver the adhesive material and to spread the adhesive material within the pleural space; characterised in that the syringe comprises two separate syringe chambers (141, 142) with moving plungers (143, 144), and a common actuator, wherein the two components of the adhesive material are deliverable from the separate syringe chambers (141, 142) into a mixing chamber connected to the catheter; and the spreading element comprises a bend formed in the catheter wherein the bend comprises a loop, an S shape, or a V shape to spread the adhesive evenly over the surfaces of the visceral and parietal pleurae (12, 14) thereby reducing the likelihood that the pleural space will again be filled with excess fluid. a pleural space access member adapted to deliver the adhesive material to the pleural space, wherein the pleural space access member comprises: an adhesive material delivery device comprising a syringe (141, 142, 143, 144, 145) and a mixing element adapted to mix the two components prior to injection of the adhesive material into a patient; and a catheter and a spreading element adapted to percutaneously deliver the adhesive material and to spread the adhesive material within the pleural space; characterised in that the syringe comprises two separate syringe chambers (141, 142) with moving plungers (143, 144), and a common actuator, wherein the two components of the adhesive material are deliverable from the separate syringe chambers (141, 142) into a mixing chamber connected to the catheter; and the spreading element comprises a bend formed in the catheter wherein the bend comprises a loop, an S shape, or a V shape to spread the adhesive evenly over the surfaces of the visceral and parietal pleurae (12, 14) thereby reducing the likelihood that the pleural space will again be filled with excess fluid. an adhesive material delivery device comprising a syringe (141, 142, 143, 144, 145) and a mixing element adapted to mix the two components prior to injection of the adhesive material into a patient; and a catheter and a spreading element adapted to percutaneously deliver the adhesive material and to spread the adhesive material within the pleural space; the syringe comprises two separate syringe chambers (141, 142) with moving plungers (143, 144), and a common actuator, wherein the two components of the adhesive material are deliverable from the separate syringe chambers (141, 142) into a mixing chamber connected to the catheter; and the spreading element comprises a bend formed in the catheter wherein the bend comprises a loop, an S shape, or a V shape to spread the adhesive evenly over the surfaces of the visceral and parietal pleurae (12, 14) thereby reducing the likelihood that the pleural space will again be filled with excess fluid.
