Abstract
A device including a hollow pipe with a variable diameter is used for medical procedures. Means are provided for reducing the diameter either internally or externally so that the pipe can be inserted into a patient's body through an incision or an opening until the distal end of the pipe reaches a desired position. Thereafter, the diameter of the pipe is increased to allow various surgical devices to be introduced through the pipe.
