• using the needle or tube like instrument to fill a part of the patient's body with gas and thereby expanding a cavity within said body,
• placing at least two laparoscopic/arthroscopic trocars in said cavity,
• inserting a camera through one of the laparoscopic/arthroscopic trocars into said cavity,
• inserting at least one dissecting tool through one of said at least two laparoscopic/arthroscopic trocars,
• dissecting an area of the pelvic bone on the opposite side from the acetabulum,
• creating a hole in said dissected area, said hole passing through the pelvic bone and into said hip joint of the patient, and
• providing said medical device to the hip joint, through said hole in the pelvic bone of the patient.
