  • Publication number: 20100057198
    Abstract: Implantable medical devices may include at least one structural element having an abluminal side, luminal side, and sidewalls between the abluminal and luminal sides. The coating may include at least two continuous coating layers. In some embodiments, the luminal side, and all or a majority of the sidewalls are free of at least two of the coating layers.

  • Publication number: 20090320261
    Abstract: A method for aligning a stent with a stent support includes the steps of (1) placing a stent support and a stent mounted on the stent support in a vertically position with the stent support's first support element at a lower position and the stent support's second support element at an upper position; (2) obtaining a digital image of the stent support and stent; (3) analyzing the digital image of the stent support and stent to compute the vertical position of the stent's upper end; (4) computing a desired position of the second support element based on the position of the stent's upper end; and (5) using a positioning device to move the second support element to the desired position. The movement of the second support element causes the conical sections of the first and second support elements to engage the respective ends of the stent to center the stent around a core element of the stent support and to secure the stent in a longitudinal direction of the stent support.

  • Publication number: 20090297583
    Abstract: The present invention generally encompasses a medical article, such as a medical device or coating comprising an agent or combination of agents, wherein the agent is distributed throughout a polymeric matrix. The polymeric matrix comprises an agent and a poly(ester amide) having a design that was preselected to provide a predetermined release rate of the combination of agents from the medical article.

  • Publication number: 20090270973
    Abstract: An intravascular stent assembly for implantation in a body lumen, such as a coronary artery, is designed to treat a lesion with vulnerable plaque by reducing the fibrous cap stresses. A polymeric sleeve having first and second ends interconnects a first metallic stent and a second metallic stent. The first end is bonded to a distal end region of the first stent and the second end to a proximal end region of the second stent. The polymeric sleeve can be loaded with a therapeutic drug or agent to further control local thrombosis and/or induce healing if the plaque fibrous cap ruptures during or after implantation. Methods of making an intravascular stent assembly for the treatment of vulnerable plaque are also provided.

  • Publication number: 20080312747
    Abstract: A system for inspecting cylinders according to various aspects of the present invention generally includes a roller assembly comprising a plurality of rollers configured to hold the cylinder. A light source illuminates the cylinder and a camera produces an image of at least a portion of the cylinder as the roller assembly rotates the cylinder about its longitudinal axis. A computer system is configured to control the roller assembly, light source, and camera and analyze the image to identify a defect associated with the cylinder.
