Method of accessing a bladder and associated apparatus therefor

摘要

A bladder access apparatus and method of provided access into a bladder through a abdominal wall therewith is provided. The apparatus has an annular body extending between opposite ends with a through passage extending between the ends. A tubular sheath is attached to one end of the body in coaxial alignment with the through passage. The sheath is expandable from a first diameter to an enlarged second diameter. The apparatus has an elongate stylet with a rod sized for receipt in the sheath. The rod has a length greater than the tubular sheath and a diameter substantially the same as the first diameter of the sheath. The apparatus includes a rigid, tubular body having an outer diameter corresponding substantially to the second diameter of the sheath and a rigid, cylindrical member sized for sliding receipt in the tubular body.
