Apparatus and methods for deployment of a modular stent-graft system

摘要

The present invention provides a modular stent-graft system. In one embodiment, a prosthesis comprises a first tubular graft comprising a layer of graft material, one lumen extending therein, and a first fenestration extending through the layer of graft material. A layer of fenestration covering material attaches to the layer of graft material. The layer of fenestration covering material is disposed in the lumen of the first tubular graft and partitions the first fenestration from the lumen of the first tubular graft. A first non-stented opening is disposed proximal to the first fenestration and communicates with the first fenestration between the layer of graft material and the fenestration covering material. In use, a proximal end of a second tubular graft sealably engages the first non-stented opening, and the second tubular graft further extends through the first fenestration and into a branch vessel.

1. A prosthesis comprising:
a first tubular graft comprising a layer of graft material, at least one lumen extending longitudinally therein, and a plurality of fenestrations extending through the layer of graft material; a layer of fenestration covering material attached to the layer of graft material, wherein the layer of fenestration covering material is disposed in the lumen of the first tubular graft and partitions the plurality of fenestrations from the lumen of the first tubular graft; a first non-stented opening disposed proximal to the plurality of fenestrations and communicating with at least one of the plurality of fenestrations between the layer of graft material and the fenestration covering material; and a second tubular graft comprising a proximal end and a distal end and a lumen extending longitudinally therebetween, where the second tubular graft sealably engages the first non-stented opening, and the second tubular graft further extends distally through one of the plurality of fenestrations and is configured to extend into a branch vessel.
