Abstract:
A system for delivering a stent within a body vessel for minimizing the risk of embolic migration, comprising:a restraining sheath adapted for expanding and retracting within the body vessel such that minimal friction exists between the restraining sheath and the stent during deployment of the stent;a filter for collecting and retaining embolic material, the filter being located relative to the restraining sheath so that the filter collects any embolic material flowing into the restraining sheath;a stent delivery catheter having an internal lumen with a proximal end open to atmospheric pressure and a distal opening extending into the restraining sheath and a region for mounting the stent thereto the filter being located within the internal lumen; andwherein the stent is initially mounted on the stent delivery catheter in a low profile collapsed state and is positioned within the restraining sheath.
