Abstract

See full text

The present invention concerns a device for segmental perfusion/aspiration of intestinal segments, including a catheter (1) having one large central channel (10) and several parallel, in relation to the central channel smaller channels (11-21) which, through holes in the outer wall of the catheter, are used for inflation of segment-delimiting balloons arranged along the catheter and around its circumference, for aspiration and perfusion of fluid from and to different segments of the intestine delimited by balloons, and for release of marker substance. The invention is characterized by that the device is shaped for introduction through the anal orifice, that the device includes two intestinal segments which are delimited by four inflatable balloons, that the device is provided with an anchoring device (2), which after introduction of the catheter is inflated in order to firmly fix the catheter to the anal orifice, and that the central channel is designed to receive an endoscope.
