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).

Abstract: A urological device comprises a urological valve for location in the bladder of a patient and a valve support stem for location in the urethra of a patient. The valve has a normally closed configuration to prevent flow from the bladder and an open configuration for fluid flow through the valve. The valve is automatically movable from the closed configuration to the open configuration in response to a pre-set hydrodynamic pressure applied for a pre-set time. In one case the valve has a plurality of valve leaflets with a region of co-aption between the valve leaflets. In the normally closed configuration the valve leaflets are engaged at the region of co-aption and in the open configuration the leaflets are separated at the co-aption region for fluid flow through the valve.

Abstract: An inexpensive small-sized screen printing machine having low redundancy and high production efficiency and applicable to a dual conveying-type component mounting machine. A pair of substrate supporting tables juxtaposed in a specific direction is provided. Screen printing is alternately performed by a single print executing section in a common area which can be shared by the two substrate supporting tables. In doing so, when one substrate supporting table located at a print position among the pair of substrate supporting tables starts exiting the print position, the other substrate supporting table starts entry to the print position.

Abstract: A valve such as an esophageal valve (1) has a normally closed configuration in which the valve (1) is closed and an open configuration in which the valve (1) is opened for flow through the valve (1). A support (102) for the valve (1) is adapted for mounting to a pre-deployed luminal prosthesis (140) intermediate a proximal end and a distal end of the predeployed luminal prosthesis (140).

Abstract: A delivery system comprises a delivery catheter with a distal capsule which contains a scaffold, a valve and a sleeve in the retracted configuration. The delivery system includes a proximal expandable element provided by an inflatable proximal balloon and a distal expandable element provided by a distal balloon. The proximal balloon provides a temporary seal at the proximal side of the valve. The distal balloon provides a temporary distal seal between a distal olive and a distal end of the sleeve. An inflation fluid is introduced into the sleeve between the proximal and distal balloons the fluid causes the sleeve to expand axially to the expanded deployed configuration. When the sleeve is in the extended deployed configuration the distal balloon is deflated, allowing the olive to detach and travel distally. The rest of the delivery system can then be withdrawn proximally, leaving the implant device in situ.
