Abstract
A surgical instrument for percutaneous accessing body tissue including a tissue piercing element for creating an opening through a body wall. The surgical instrument may include a working member for performing a surgical procedure within the body. Alternatively, the surgical instrument may include an introducer having a stabilizing structure for facilitating the passage of the tissue piercing element and for releasably affixing the surgical instrument to the body tissue surface, thereby securing the surgical instrument relative to the patient's body.
