摘要:
A medical treatment device (200), for treating reflux from a stomach (201) toan oesophagus(202) and for delivering a therapeutic agent to an inner surface of theoesophagus (202),comprises a valve member (203), a lining member (204), and a support member(205). Thevalve member (203) is movable between a closed configuration and an openconfiguration,in which the valve member (203) facilitates passage of material between theoesophagus(202) and the stomach (201). The valve member (203) is biased towards theclosedconfiguration and gradually moves over a period of 4 to 10 sees from the openconfigurationto the closed configuration. The support member (205) supports the device(200) relative tothe oesophagus (202) and the stomach (201). The lining member (204) lines partof the innersurface of the oesophagus (202) for delivery of a therapeutic agent to theoesophagus (202).
