Medical device suitable for treating reflux from a stomach to an oesophagus

Abstract

A medical treatment device ( 200 ), for treating reflux from a stomach ( 201 ) to an oesophagus ( 202 ) and for delivering a therapeutic agent to an inner surface of the oesophagus ( 202 ), comprises a valve member ( 203 ), a lining member ( 204 ), and a support member ( 205 ). The valve member ( 203 ) is movable between a closed configuration and an open configuration, in which the valve member ( 203 ) facilitates passage of material between the oesophagus ( 202 ) and the stomach ( 201 ). The valve member ( 203 ) is biased towards the closed configuration and gradually moves over a period of 4 to 10 secs from the open configuration to the closed configuration. The support member ( 205 ) supports the device ( 200 ) relative to the oesophagus ( 202 ) and the stomach ( 201 ). The lining member ( 204 ) lines part of the inner surface of the oesophagus ( 202 ) for delivery of a therapeutic agent to the oesophagus ( 202 ).

1 . A medical device suitable for treating reflux from a stomach to an oesophagus, the device comprising:
 a valve member;   the valve member being movable between an open configuration to facilitate passage of material between an oesophagus and a stomach, and a closed configuration;   the valve member being configured to gradually move from the open configuration to the closed configuration over a predetermined period of time.
