    摘要: A coated implantable medical device 10 includes a structure 12 adapted for introduction into the vascular system, esophagus, trachea, colon, biliary tract, or urinary tract; at least one coating layer 16 posited on one surface of the structure; and at least one layer 18 of a bioactive material posited on at least a portion of the coating layer 16, wherein the coating layer 16 provides for the controlled release of the bioactive material from the coating layer. In addition, at least one porous layer 20 can be posited over the bioactive material layer 18, wherein the porous layer includes a polymer and provides for the controlled release of the bioactive material therethrough. Preferably, the structure 12 is a coronary stent. The porous layer 20 includes a polymer applied preferably by vapor or plasma deposition and provides for a controlled release of the bioactive material. It is particularly preferred that the polymer is a polyamide, parylene or a parylene derivative, which is deposited without solvents, heat or catalysts, and merely by condensation of a monomer vapor.

    摘要: The present invention provides a wire guide having a variable stiffness region that may be selectively adjusted to vary the stiffness along a portion of the wire guide. The wire guide generally comprises an outer core member and an inner core member, wherein the inner core member is disposed for longitudinal movement with respect to the outer core member. The outer core member is attached to a proximal end of a coiled member, while the inner core member is attached to the coiled member at an attachment region between proximal and distal ends of the coiled member. In operation, distal advancement of the outer core member with respect to the inner core member causes the coiled member to compress at a location between the proximal end of the coiled member and the attachment region, thereby selectively increasing the stiffness along a portion of the length of the wire guide.

    摘要: A method of filtering blood in a blood vessel of a patient wherein a catheter is initially introduced into the blood vessel and then advanced to a desired location within the blood vessel. Subsequently, a portion of a positioning assembly having a filter distally attached thereto is guided through the catheter. The filter is then positioned at a location beyond the distal end of the catheter within the blood vessel with the positioning assembly. The positioning assembly is then locked to the catheter. The catheter is then anchored to an object located outside of the blood vessel. Thereafter, an amount of blood is filtered within the blood vessel with the filter. The filter can be readily repositioned by unlocking the positioning assembly from the catheter, repositioning the filter within the blood vessel with the positioning assembly and then relocking the positioning assembly to the catheter.
