Flexible stent-graft with polymeric non-textile graft layers
The patent US12016768B2 describes an innovative endovascular stent-graft designed for vascular applications. The stent-graft features an undulating wire that is helically wound into multiple circumferential windings, characterized by peaks and valleys. This structure allows for a combination of a graft liner and a graft cover, which are selectively secured to each other through a process involving heat and compression. The secured portions are defined within specific areas bounded by the undulations of the wire, while adjacent areas remain unsecured, facilitating flexibility and adaptability in various vascular environments. The design also allows for configurations that enable the stent-graft to bend significantly without compromising its tubular shape or diameter.
Additionally, the claims outline various configurations and characteristics of the stent-graft, including the absence of interconnecting struts and welds between adjacent windings, and the potential for pleated or crimped portions in the graft cover. The secured graft portions can vary in longitudinal extent relative to the thickness of the undulating wire, enhancing the stent-graft's performance. The design ensures that the graft liner and cover maintain structural integrity while allowing for movement and flexibility, which is crucial for successful implantation and function within the vascular system. Overall, this patent presents a sophisticated approach to stent-graft technology, emphasizing both structural innovation and functional adaptability.
