Abstract
In a surgical method, an access sheath is provided by a tube of a braided material. A first end of the sheath may be folded. The first end, folded or unfolded, is grasped with a distal end of a tool, which is then inserted into the nose of a patient. Advancing the tool pulls the distal end of the sheath into the nose of the patient. The sheath is then released from the tool and the tool is withdrawn. A portion of the sheath may be optionally cut off to shorten the sheath to a desired length. Typically the sheath has a total length of 70 to 180 mm and an outside diameter of 12 to 50 mm. The sheath may have a constant outside diameter along its length. The sheath may comprise silicone on the braided material.
