Medical device sheath apparatus and method of making and using same

摘要

A medical device sheath apparatus including: a fitting being suitable for receiving the medical device in a self sealing manner; a first sheath for receiving the medical device as it passes through the fitting; a second sheath surrounding the first sheath; a dilator defining a treatment area, coupled to at least the second sheath, and being suitable for dilating a bodily cavity and passing therapeutic or diagnostic energy in such forms as electromagnetic radiation or acoustic energy there through; and, a window operatively positioned with respect to the first sheath so as to enable viewing of an area substantially adjacent the second sheath upon insertion of the medical device into the apparatus. A method for irradiating at least a portion of a bodily cavity including: providing a sheath apparatus including: a fitting being suitable for receiving the medical device in a self sealing manner; a first sheath for receiving the medical device as it passes through the fitting; a second sheath surrounding the first sheath; a dilator defining a treatment area, coupled to at least the second sheath, and being suitable for dilating a bodily cavity and passing therapeutic or diagnostic energy in such forms as electromagnetic radiation or acoustic energy there through; and, a window operatively positioned with respect to the first sheath so as to enable viewing of an area substantially adjacent the second sheath upon insertion of the medical device into the apparatus; inserting at least a portion of the medical device into the apparatus; positioning the medical device containing apparatus in the bodily cavity using direct viewing through the window and the medical device; and, irradiating the portion of the bodily cavity through the apparatus using the medical device.
