Abstract: A monoscopic imaging system, for example a minimally invasive surgery imaging system, is provided which includes an image capture device for capturing images of a monoscopic, for example endoscopic, field of view, an auxiliary light source operable such that an object within the field of view casts a shadow, an image processor operatively connected to the image capture device and operable to detect shadow pixels in the images corresponding to the shadow and to enhance the shadow in the images. The system is of particular, although not exclusive, application to laparoscopic surgery.

Abstract: In a remote controlled robotic manipulator 20 a motion sensor 26 senses motion of a region of an object to be manipulated. A controller 50 locks motion of the robotic manipulator 26 relative to the region of the object and also selects the region of the object to be sensed. As a result the frame of reference of the manipulator is locked to the relevant region of the object to be manipulated improving ease of control and manipulation.

Abstract: A device for causing dilation of a tubular anatomy comprising; an active element comprising: a plurality of elongate flexible members, each having a first end and a second end; a first connector connected to the first ends of the strips; a second connector connected to the second ends of the strips; a compressor for causing one of the connectors to move towards the other connector thereby causing the elongate members to bow laterally.
