摘要:
The present embodiments provide stents for use in medical procedures. In one embodiment, a stent comprises a first flanged region and a body region. A first diameter of the first flanged region is greater than a second diameter of the body region when the stent is in an expanded deployed state. A proximal junction is formed between the first flanged region and the body region. The proximal junction comprises at least one strut extending from the distal end of the first flanged region in a distal direction towards the proximal end of the body region. A strut at the proximal end of the body region is disposed around at least a portion of the strut of the proximal junction. The overlap between the strut at the proximal end of the body region with the strut of the proximal junction causes an increased radiopaque effect at the proximal junction.
