AI Technical Summary

Benefits of technology

The present invention provides a stent with additional markers that can be easily seen on an image. These markers are placed on the stent in a specific way to improve its visibility during a medical imaging technique.

Problems solved by technology

The ability to monitor or detect a stent visually is limited by the visibility of the markers.

Embodiment Construction

[0025]The present invention may be applied to stents and, more generally, implantable medical devices such as, but not limited to, self-expandable stents, balloon-expandable stents, stent-grafts, vascular grafts, cerebrospinal fluid shunts, pacemaker leads, closure devices for patent foramen ovale, and synthetic heart valves.

[0026]A stent can have virtually any structural pattern that is compatible with a bodily lumen in which it is implanted. Typically, a stent is composed of a pattern or network of circumferential and longitudinally extending interconnecting structural elements or struts. In general, the struts are arranged in patterns, which are designed to contact the lumen walls of a vessel and to maintain vascular patency. A myriad of strut patterns are known in the art for achieving particular design goals. A few of the more important design characteristics of stents are radial or hoop strength, expansion ratio or coverage area, and longitudinal flexibility. The present inven...

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This is a continuation of application Ser. No. 11 / 796,226, filed on Apr. 26, 2007 which in turned claims benefit of provisional application No. 60 / 809,088, filed on May 26, 2006, both of which are incorporated herein by reference in their entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to implantable medical devices, such as stents. In particular, the invention relates to polymeric stents with radiopaque markers.[0004]2. Description of the State of the Art[0005]This invention relates to radially expandable endoprostheses, which are adapted to be implanted in a bodily lumen. An “endoprosthesis” corresponds to an artificial device that is placed inside the body. A “lumen” refers to a cavity of a tubular organ such as a blood vessel. A stent is an example of such an endoprosthesis. Stents are generally cylindrically shaped devices, which function to hold open and sometimes expand a segment of a ...
