Abstract: A method of performing a surgical procedure on a body includes providing a cannula having a tubular structure with first and second tubular portions defining first and second passages for receiving surgical instruments. The second tubular portion is inserted inside the body and the first tubular portion is inserted so that the first tubular portion extends from an exterior of the body to inside the body. The second tubular portion expands to increase the cross-sectional area of the second passage in the second tubular portion while the second tubular portion is inside the body. The cross-sectional area of the first passage in the first tubular portion is maintained. The first tubular portion has a first thickness and the second tubular portion has a second thickness different than the first thickness.

Abstract: A cannula (10) receives surgical instruments (120) for performing a surgical procedure on a body (130). The cannula (10) comprises a tube structure (12) defining a passage (16) through which the surgical instruments (120) are inserted into the body (130). The tube structure (12) has a proximal end (20) and a distal end (62). The tube structure (12) includes an expandable portion (40) for enabling an increase in the cross-sectional area of the passage (16) at the distal end (62). The expandable portion (40) of the tube structure (12), when expanded, has a conical configuration.

Abstract: A method of fixing first and second vertebrae of a patient together at a surgical site includes inserting a first cannula into the body of the patient. A fusion device is moved through the cannula and inserted between the first and second vertebrae. A first fastener is moved through the cannula and secured to the first vertebra. A second fastener is moved through the cannula and secured to the second vertebra. A first fixation element is moved through the cannula. The first fixation element is fixed to the first and second fasteners. The fusion device has first and second ends, upper and lower surfaces for engaging the first and second vertebrae, and first and second side surfaces extending between the upper and lower surfaces. Each of the first and second side surfaces extend along an arc from the first end of the fusion device to the second end. The upper and lower surfaces have teeth that extend between the first and second side surfaces along secant lines of circles partially defined by the first and second side surfaces.

Abstract: The ultrasonic scalpel blade includes a blade having an included blade edge angle of 25.degree. and greater such that, upon application of ultrasonic power, the otherwise blunt blade has a perceived sharpness corresponding to the sharpness of manually used scalpel blades with the added advantage of improved coagulation and hemostasis. Blades are also provided with varying included angles for ultrasonically incising different tissues.
