20100145224 | CANAL DILATION DEVICE - A device for enlarging a canal of a human or animal subject includes an elongate member having a first lumen extending therein and an inflatable body toward a distal end of the elongate member. The inflatable body is deliverable, in an uninflated or deflated state, to a location substantially within the canal prior to inflation. The first lumen is in communication with the inflatable body via one or more channels therebetween. In use, the first lumen is in communication, toward a proximal end, with an inflation system for delivering fluid to inflate the inflatable body and thereby enlarging the canal. The device may include markings for sounding of e.g. uterine depth. The device may also include one or more projections, or other structure providing tactile cues during positioning of the device within the canal and these may also be configured to aid in removal of cells from a tissue wall. | 06-10-2010 |
