  • REDUCED SLIPPAGE BALLOON CATHETER AND METHOD OF USING SAME
    Publication number: 20090005732
    Abstract: A balloon catheter having a balloon with a reduced slippage lubricious coating, and a method of performing a medical procedure such as a balloon dilatation procedure in a patient's blood vessel. The second coating (i.e., the balloon coating) is lubricious to facilitate movement of the catheter in the patient's body lumen, yet has sufficiently low lubricity such that the slippage of the inflated balloon from a desired site within the blood vessel is reduced compared to a balloon coated with the first lubricious coating.
    Type: Application

  • Polymeric stent patterns
    Patent number: 7291166
    Abstract: Patterns for polymeric radially expandable implantable medical devices such as stents for implantation into a bodily lumen are disclosed. Some patterns comprise radially expandable cylindrical rings that are longitudinally aligned, each ring comprising diamond-shaped elements, each formed by four linear bar arms. The patterns con also comprise a cross-like element comprising four linear bar arms interconnected within the diamond-shaped elements, and at least one link between adjacent rings. In other patterns, the rings comprise peaks and valleys formed by linear bar arms. wherein pairs of rings are configured such that the peaks of one pair are connected to the valleys of the other pair at apices of the peaks and valleys to form diamond shaped regions. In yet other patterns, there are two v-shaped elements formed by two short bar arms within the diamond-shaped elements, and a connecting bar arm connecting the two v-shaped elements.
