摘要 |
The present invention relates to an expansible tunneling apparatus suitable for tissue dissection. The apparatus is provided with a cannula-loading shaft at its proximal end such that a cannula chosen from a range of different cannulas may be loaded over the cannula-loading shaft and installed in an anatomic space created by the expansible tunneling apparatus. The apparatus is also provided with an inflatable member such as a balloon to accomplish the dissection and a sleeve covering the balloon which are removed from the apparatus before the cannula is loaded on the cannula loading shaft.
