  • Intravascular stent and method of use
    Patent number: 8343209
    Abstract: An expandable stent is implanted in a body lumen, such as a coronary artery, peripheral artery, or other body lumen for treating an area of vulnerable plaque. The invention provides for a an intravascular stent having a plurality of cylindrical rings connected by undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. A central section is positioned between distal and proximal sections and is aligned with the area of vulnerable plaque to enhance growth of endothelial cells over the fibrous cap of the vulnerable plaque to reinforce the area and reduce the likelihood of rupture.

  • INTRAVASCULAR STENT
    Publication number: 20120330403
    Abstract: The invention is directed to an expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The invention provides for an intravascular stent having a plurality of cylindrical rings connected by undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. The stent can be compressed or crimped onto a catheter to a very low profile since the peaks that are adjacent the curved portion of the undulating link are shorter than other peaks in the same cylindrical ring to prevent overlap yet still achieve a very low profile, tightly crimped stent onto a catheter.

  • Stent for treating bifurcations and method of use
    Patent number: 8337540
    Abstract: An improved stent design and stent delivery catheter assembly for repairing a main vessel proximal to a side branch vessel and the opening to the side branch vessel forming a bifurcation. The stent is particularly useful in treating a bifurcation where plaque is present proximal to the side branch vessel but not distal to the side branch vessel. The present invention includes a trap door stent design, a stent delivery catheter assembly, and the method for delivering and implanting the stent in a bifurcated vessel. More particularly, the invention relates to a stent having rings aligned along a common longitudinal axis and connected by links. The stent has first rings that are implanted in the main vessel proximal to the bifurcation and one or more second rings forming a trap door section to appose the opening to the side branch vessel and the main vessel.

  • Methods for improving stent retention on a balloon catheter
    Patent number: 8333000
    Abstract: A method of crimping a stent on a balloon of a catheter assembly is provided. A polymeric stent is disposed over a balloon in an inflated configuration. The stent is crimped over the inflated balloon to a reduced crimped configuration so that the stent is secured onto the balloon. The balloon wall membrane is wedged or pinched between the strut elements of the stent for increasing the retention of the stent on the balloon.

  • Methods for laser cutting and processing tubing to make medical devices
    Patent number: 8333897
    Abstract: A method for making a device includes providing a tubular member which will be formed into the device, masking at least a portion of the inner surface of the tubular member with a removable sacrificial material, selectively removing a portion of the tubular member and sacrificial material using a laser device, and mechanically removing the sacrificial material from the inner surface of the tubular member. Ultrasonic energy could be applied to a workpiece which is being laser cut to prevent any generated slag from welding itself to an exposed surface of the workpiece. A compressed fluid or gas, such as air, could be used to clean the surface of the laser-cut workpiece to remove slag formation which adheres to the surface of the cut workpiece.

  • Coating abluminal surfaces of stents and other implantable medical devices
    Patent number: 8312838
    Abstract: A sleeve is positioned over a radially-expandable rod assembly and a stent is positioned over the sleeve. A mandrel is inserted into the rod assembly to thereby press the sleeve against the inner surface of the stent and expand the stent. A coating (such as a solvent, a polymer and/or a therapeutic substance) is then applied to the outer (abluminal) surfaces of the stent, by spraying, for example. The sleeve advantageously prevents the coating material from being applied to inner (luminal) surfaces of the stent and also allows the coating material to be efficiently applied to the abluminal surfaces.

  • Catheter shaft with a lubricious surface
    Patent number: 8308711
    Abstract: A catheter which has an elongated shaft having a layer of an ultra high molecular weight polyolefin, such as a melt-extruded ultra high molecular weight polyethylene (UHMWPE). The UHMWPE, forming at least in part a surface of the shaft, facilitates sliding a blood/contrast coated device along the shaft surface, and preferably substantially prevents or inhibits agglomerations of blood and contrast from adhering to the surface of the shaft in a patient's body lumen. In a presently preferred embodiment, the layer has a lubricious coating, such that the coated surface of the UHMWPE layer significantly decreases the force produced by the blood/contrast coated device sliding along the coated surface.
