SURGICAL SHEATH WITH INSTRUMENT FIXATION STRUCTURES

摘要

A surgical sheath having a lumen extending therethrough along a longitudinal axis is provided with an inflatable external member that is selectively inflated to secure the sheath in a desired position within a patient's body. An internal inflatable member is positioned within the lumen of the sheath, which is selectively inflatable to secure a device, such as a light source, within the sheath as a desired depth of penetration within the patient's body. To aid a user in positioning the sheath in a desired location, a reference scale may be provided on an outer surface of the sheath.
