  • Patent number: 9056157
    Abstract: An intraluminal stent, an intraluminal stent delivery system, and a method of treating a vascular condition. The stent includes a framework composed of a biodegradable material. At least one strut is composed of a non-biodegradable material. The framework is operably attached to the at least one strut. The delivery system includes a catheter and a stent disposed on a portion of the catheter. The stent includes a framework composed of a biodegradable material. The stent further includes at least one strut composed of a non-biodegradable material. The framework is operably attached to the at least one strut. The method includes positioning an intraluminal stent via a catheter within a vessel. The stent includes at least one strut that is composed of a non-biodegradable material and is operably attached to a framework. The framework expands during deployment of the intraluminal stent. The framework is allowed to biodegrade within the vessel.

  • Patent number: 7749262
    Abstract: An intraluminal stent, an intraluminal stent delivery system, and a method of treating a vascular condition. The stent includes a framework with a plurality of flap portions projecting substantially beyond a central core region. The flap portions are movable from a compressed position and an extended position when the stent is deployed. The system includes a catheter and the intraluminal stent. The method includes positioning an intraluminal stent within a vessel. A plurality of flap portions of the stent is extended from a compressed position into contact with the vessel.

  • Publication number: 20100168833
    Abstract: An intraluminal stent, an intraluminal stent delivery system, and a method of manufacturing a stent. The stent (40) includes a stent body having a plurality of struts (46). The struts (46) are positioned to minimize overlap one to another when the stent is rolled at an angle. The rolled stent is in a compressed configuration. The system further includes a catheter and the stent disposed on a portion of the catheter. The manufacturing method includes providing a stent body including a plurality of struts, and helically rolling the stent at an angle to minimize overlap of the struts one to another.

  • Publication number: 20080269869
    Abstract: An intraluminal stent, an intraluminal stent delivery system, and a method of treating a vascular condition. The stent includes a stent body with a plurality of struts. The stent body is expandable from a compressed configuration to a deployed configuration. The struts include at least one sliding assembly for locking the stent body in the deployed configuration. The at least one sliding assembly allows sliding of adjacent struts one to another while the stent body is expanding. The system further includes a catheter and the stent disposed on a portion of the catheter. The method includes positioning an intraluminal stent with a catheter within a vessel. The stent includes minimized overlap of adjacent struts while in a compressed configuration. The stent is expanded from the compressed configuration to an deployed configuration where it is locked. Adjacent struts slide relative one to another while the stent is expanding.
