Abstract:
1. A catheter assembly for endoluminal deployment of a medical device, said catheter assembly comprising: a catheter having a trailing end and a leading end; an expandable stent graft disposed toward the leading end of the catheter; a sleeve for constraining the expandable stent graft toward an outer peripheral dimension suitable for endoluminal delivery of the stent graft, the sleeve having opposite first and second ends, the sleeve comprising a sheet of film having opposite inner and outer surfaces each extending between the first and second ends of the sleeve; a first deployment line releasably coupling spaced apart sides of the sleeve to constrain a first portion of the stent graft; and a second deployment line releasably coupling spaced apart sides of the sleeve to constrain a second portion of the stent graft, an actuator coupled to the first deployment line and second deployment line, wherein the actuator is configured to decouple the first deployment line and second deployment line from the sleeve to cause opening of the first and second portions of the sleeve, respectively; wherein the first and second deployment lines are operatively coupled to each other so as to delay opening of the second portion until substantially after opening of the first portion when the actuator is pulled away from the catheter.
