A recently granted patent (Publication Number: US11865018B2) discloses a method for manufacturing a stent device that involves providing cylindrical rings made up of repeating bent segments with peaks, valleys, and transition regions. These rings are interconnected by fusiform-shaped interconnecting members arranged in rows along the device, alternating between two orientations. The patent also covers a stent device comprising expandable rings connected by interconnecting members, encapsulated in a cover made of expanded polytetrafluoroethylene to reduce foreshortening upon expansion to an operational deployment diameter.

The stent device described in the patent features a unique design with radially expandable rings connected by interconnecting members in a specific orientation to minimize foreshortening upon expansion. The covered stent device aims to exhibit minimal foreshortening, ranging from 6% to 0% when expanded to an operational deployment diameter between 4mm to 8mm. The patent also details the arrangement of interconnecting members between rings, the alignment of coupling ends, and the sinusoidal shape formed by the interconnecting members along the length of the stent. Additionally, the patent specifies the configuration of the bent segments within the rings to ensure optimal performance and structural integrity of the stent device.
