  • Publication number: 20140058208
    Abstract: An adjustable length sheath and a method for adjusting the length of a sheath is disclosed. The adjustable length sheath is primarily designed for uretral access, and for the insertion of a dilator or other medical equipment. The adjustable length sheath has and end cap that is removably attachable, and a proximal end with circumferential grooves cut lateral to the axis of said sheath such that it is possible to snap off a portion of the proximal end to adjust the length of the sheath. The proximal end may be made of a different material that has a lower degree of flexibility than the main body of the sheath to allow the end to be more easily broken. The end cap has a lip to prevent the sheath from sliding through said end cap.
