DELIVERY DEVICE WITH AN EXTENSION SHEATH AND METHODS OF USING THE SAME

摘要

Methods for delivering and deploying an endovascular graft to the common and internal iliac arteries are described. A system including a pre-loaded delivery device with a releasably attached extension cannula and an extension sheath for use with such methods is also described.

主权项

1. A prosthesis delivery device comprising:
an inner cannula having a proximal end; a nose cone dilator extending proximally from the proximal end of the inner cannula, the nose cone having a proximal end and a distal end and a groove extending longitudinally along at least a portion of an outer surface of the nose cone between the proximal and distal ends; an extension cannula having a proximal end and a distal end releasably attached to the proximal end of the nose cone; an extension sheath coaxial with at least a portion of the extension cannula, wherein the extension sheath has a proximal end and a distal end and a lumen extending between the proximal and distal ends, a main sheath having a proximal end, a distal end and a lumen extending therebetween, wherein the main sheath has a first position in which a proximal end of the main sheath is coaxial with the distal end of the extension sheath and a second position in which the proximal end of the main sheath is distal to the distal end of the extension sheath; a pre-loaded guide wire extending proximally at least partially through the lumen of the main sheath, through the groove formed in the nose cone and proximally at least partially through the lumen of the extension sheath.
