Radial distention of a soft tissue space using a finger guided distention balloon

摘要

A device for radially distending a soft tissue space comprising a finger sheath for covering at least one finger. The sheath has a proximal and distal end. A distention balloon is attached to the distal end of the sheath. The balloon has a relative deflatable position in relation to the finger sheath and a relative inflatable position in relation to the sheath. An inflation source for inflating the distention balloon to a preferred volume thereby dilating the desired the soft tissue space is provided. A valve member for deflating the balloon is also provided.
