Abstract
An obturator provides access to a joint through a capsule surrounding the joint. A distal end of the obturator has a first distal location with a first width dimension and a second distal location with a second width dimension, wherein the second distal location is proximal to the first distal location and the second width dimension greater than the first width dimension. A retractable blade can extend from the obturator to be exposed between the first distal location and the second distal location.
