Patent ID: 7338518

Claim:
A method for deploying an expandable intracorporeal device within a patient's body comprising: providing a catheter system including: an elongate shaft having a proximal section, a distal section, a proximal end and a distal end, the distal section of the elongate shaft comprising a radially expandable shear barrier disposed about an inner space configured to accept the expandable intracorporeal device in a collapsed state, the radially expandable shear barrier comprising a slitted tubular section, an outer radially constraining section which is disposed about and radially constrains at least a portion of the radially expandable shear barrier, and the expandable intracorporeal device disposed within the inner space of the radially expandable shear barrier; introducing the distal end of the catheter system into the patient's body; advancing the catheter system to a desired site within the patient's body; and initiating relative axial movement between the radially expandable shear barrier and the outer constraining section to a least partially remove the radial constraint on the radially expandable shear barrier sufficiently for the expandable intracorporeal device to expand and deploy at the desired site, wherein the outer radially constraining section comprises an outer tubular section and the expandable intracorporeal device comprises an expandable endovascular graft having an expandable anchor portion disposed within an inner lumen of the outer tubular section distal of a distal end of the slitted tubular section prior to initiation of relative axial movement between the slitted tubular section and the outer tubular section.
