1. A method of performing a surgical procedure on a body comprising:
providing a cannula having a tubular structure with first and second tubular portions defining first and second passages for receiving surgical instruments, the second passage being a continuation of the first passage, the first and second tubular portions having an exterior surface comprising a continuous surface;
inserting the cannula through an incision in the body made near the spinal region of the body;
inserting the second tubular portion inside the body such that the second tubular portion is adjacent at least one vertebra such that the exterior surface of the second tubular portion engages the tissue of the body surrounding the vertebra;
inserting the first tubular portion of the cannula into the incision so that the first tubular portion extends from an exterior of the body to inside the body such that the exterior surface of the cannula engages the body when being inserted;
expanding the second tubular portion of the cannula to increase the cross-sectional area of the second passage in the second tubular portion while the second tubular portion is inside the body such that the exterior surface of the second tubular portion retracts the tissue surrounding the vertebra to provide a complete passage from exterior the body to the region of the vertebra; and
inserting a plurality of instruments through the passage to perform a procedure in the region of the vertebrae.
2. A method of performing a surgical procedure as set forth in claim 1 wherein expanding the second tubular portion of the cannula includes expanding the second tubular portion of the cannula from a cylindrical configuration into a conical configuration.
providing a structure having a proximal portion and a distal portion and defining a passage for receiving instruments extending from the proximal portion to the distal portion, the structure having an exterior surface;
inserting the structure in the body near the spinal region of the body;
advancing the structure into the body such that at least the distal portion of the structure is positioned adjacent at least one vertebra of the body and such that the exterior surface of the structure in the distal portion engages the tissue of the body surrounding the vertebra; and
expanding at least the distal portion of the structure to increase the cross-sectional area of the passage in the distal portion of the structure such that the exterior surface of the structure in the distal portion retracts the tissue surrounding the vertebra; and
inserting a plurality of instruments through the passage to perform a procedure.
26. A method of performing a surgical procedure as set forth in claim 25 further including maintaining the cross-sectional area of the passage at the proximal end of the structure while increasing the cross-sectional area of the passage at the distal end.
providing a structure having an inner surface defining a passage extending through the structure and through which instruments are inserted into the body, the inner surface extending entirely around a longitudinal axis of the structure, the structure having a proximal end and a distal end, the passage having a first cross-sectional area adjacent the distal end;
inserting the structure through an incision in the body including inserting the structure into the incision so that the distal end of the structure is located inside the body and adjacent the spine; and
increasing the cross-sectional area of the passage adjacent the spine to a second cross-sectional area which is greater than the first cross-sectional area with the inner surface extending entirely around the longitudinal axis when the cross-sectional area of the passage adjacent the spine is increased.
47. A method of performing a surgical procedure as set forth in claim 46 wherein increasing the cross-sectional area of the passage adjacent the spine includes increasing the cross-sectional area of the passage at the distal end of the structure to a cross-sectional area greater than a cross-sectional area of the passage at the proximal end of the structure.
inserting the structure in the body;
advancing the structure into the body such that at least the distal portion of the structure is positioned adjacent a surgical location and such that the exterior surface of the structure in the distal portion engages the tissue of the body near the surgical location; and
expanding at least the distal portion of the structure to increase the cross-sectional area of the passage in the distal portion of the structure such that the exterior surface of the structure in the distal portion retracts the tissue near the surgical location.
62. The method of claim 61, wherein the surgical location is adjacent to a joint.
advancing the structure into the body such that at least the distal portion of the structure is positioned on a portion of at least one vertebra of the body and such that the exterior surface of the structure in the distal portion engages the tissue of the body surrounding the vertebra;
advancing the structure into the body such that at least a portion of the proximal portion of the structure remains exterior to the body;
said passage in at least the distal portion of the structure being defined by a cross-sectional area having a dimension which is greater along a first axis that it is along a second axis that is perpendicular to the first axis; and
66. The method of claim 65, wherein when the structure is applied to the patient, the first axis extends generally parallel to the spine.
