Telescoping Stability Sheath and Method of Use
First Claim
1. A telescoping stability sheath for use with a stent delivery system having a delivery catheter and an introducer, the delivery catheter having a retractable sheath and a retractable sheath axially slidable within a stability sheath stop, the introducer having an introducer fitting slidably tightenable about the retractable sheath, the telescoping stability sheath comprising:
- a first segment slidably disposed about the retractable sheath;
a second segment slidably disposed about the first segment; and
a stability fitting attached to at least one of the first segment and the second segment;
wherein the stability fitting fixes a set length between the introducer fitting and the stability sheath stop when the stability fitting is engaged to lock the first segment to the second segment.

Abstract
A telescoping stability sheath and method of use, including a telescoping stability sheath for use with a stent delivery system having a delivery catheter and an introducer, the delivery catheter having a retractable sheath and a stability sheath stop axially slidable on the retractable sheath, the introducer having an introducer fitting slidably tightenable about the retractable sheath axially slidable within a sheath stop. The telescoping stability sheath includes a first segment slidably disposed about the retractable sheath, a second segment slidably disposed about the first segment, and a stability fitting attached to at least one of the first segment and the second segment. The stability fitting fixes a set length between the introducer fitting and the stability sheath stop when the stability fitting is engaged to lock the first segment to the second segment.
