  • Patent number: 8747457
    Abstract: A stent (10) has wrapped therearound a barb element (12) formed of a length of wire provided with first and second ends (14, 16) forming barb prongs. In intermediate zone (22), the barb element (12) is wrapped or coiled. The two pronged ends (14, 16) extend out of the graft element (26) to provide an anchoring function to the medical device. As well as being wrapped onto a strut of the stent (10), the barb element (12) is sutured to the stent (10) and to the graft material (26) by suture stitching (28). The turns of the coiling or wrapping in section (22) assist in fixing the barb element (12) relative to the suture (28) and thus to the stent graft (24). The barb elements (12) could be made of any suitable material, including Nitinol. This structure of barb elements provides an effective arrangement which is easy to manufacture, which provides strong barbs able to withstand the high processing temperatures required for setting shape memory elements of the device.

  • Patent number: 8740972
    Abstract: An implantable medical support frame (104) having a central longitudinally extending axis is expandable from a collapsed configuration having a first diameter to an expanded configuration having a second diameter. The frame also includes an anchoring mechanism with an elongate member (110). At least a portion of the elongate member is slidably disposed within a retaining structure when the frame is in the collapsed configuration. When the frame expands from the collapsed configuration to the expanded configuration, a portion of the elongate member is advanced out of the retaining structure such that the portion of the elongate member protrudes radially outward of the frame at an angle to the axis, thereby forming an anchor. A length of the protruding portion of the anchor increases as the frame expands from the collapsed configuration to the expanded configuration.
