US Patent 11992219 Implantable medical device and assembly

Disclosed is a false lumen closure assembly for closing a false lumen in a body vessel including a compressed false lumen occluder, a carrier catheter and a retractable sheath. The compressed false lumen occluder includes a stent graft including at least one occlusive barrier across the stent graft to occlude blood flow through an interior of the stent graft. The carrier catheter carries the false lumen occluder and extends from a proximal end proximal of the false lumen occluder to a distal end distal of the false lumen occluder, and passes the false lumen occluder exteriorly of the stent graft. The compressed false lumen occluder and at least part of the carrier catheter are disposed in a lumen of the retractable sheath.
