Patent ID: 7066951

Claim:
A method for deploying an expandable intracorporeal device within a patient's body comprising: a) 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 of the elongate shaft configured to accept the expandable intracorporeal device in a collapsed state, an outer radially constraining section which is disposed about and radially constrains at least a portion of the radially expandable shear barrier, the expandable intracorporeal device disposed within the inner space of the radially expandable shear barrier, the expandable intracorporeal device comprising an injection port in fluid communication with an inflatable portion of the expandable intracorporeal device, and an injection lumen which is disposed within the inner space of the elongate shaft, wherein the injection lumen is configured to be removably coupled to the injection port; b) introducing the distal end of the catheter system into the patient's body; c) advancing the catheter system to a desired site within the patient's body; d) initiating relative axial movement between the radially expandable shear barrier and the outer constraining section to at 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, and e) injecting an inflation material through the injection lumen and into the injection port.
