ENDOLUMINAL STENT GRAFT WITH SUTURED ATTACHMENT

摘要

An endoluminal prosthetic device for placement in a body lumen is formed by stitching stents to a graft. A first or anchoring stent (12) is used for securing a graft made of biocompatible material that forms at least one lumen. There is also a second stent (14). The first and second stents each include a plurality of struts (15, 25) and apices (16, 26) between the struts. At least two of the apices in each of the first and second stents are secured to the graft by stitches (21, 23). A running suture (24) links at least one stitch of the first stent and one stitch of the second stent. The running suture linking the first stent and the second stent adds strength to the stitches and better secures the first stent to the device. The endoluminal prosthetic device may be used in an aortic vessel to treat stenoses or aneurysms.
