    摘要: An introducer system for introducing a plurality of wire guides into a vessel of a patient includes first and second wire guides, and a catheter. The first wire guide has a curved proximal end, and a distal end sufficiently flexible for passage through the vessel to a target site for the procedure. The catheter has proximal and distal open ends, and a lumen extending therebetween. At least the distal end of the catheter has sufficient flexibility for passage over the first wire guide to the target site, and has an inwardly curved portion between the proximal and distal open ends. The catheter further has a side port proximally positioned along the inwardly curved portion. The side port is sized and arranged such that the curve of the first wire guide proximal end is passable therethrough when the catheter is passed over the first wire guide. The second wire guide is sized for passage through the lumen when the first wire guide is positioned in the lumen. The second wire guide has a stiffness greater than the stiffness of the first wire guide.

    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, and at least one layer 18 of an immunosuppressive agent posited over at least one surface of the structure 12. Optionally, the device 10 can include at least one porous, preferably polymeric layer 20 posited over the layer 18 of immunosuppressive agent, and can alternatively or additionally include at least one coating layer 16 posited on one surface of the structure 12, the at least one layer 18 of immunosuppressive agent being posited in turn on at least a portion of the coating layer 16. The porous layer 20 and the coating layer 16 each provide for the controlled release of the bioactive material from the device 10. The structure 12 is preferably configured as a coronary stent. The polymer of the porous layer 20 is preferably applied by vapor or plasma deposition. It is particularly preferred that the polymer is a polyamide, parylene or a parylene derivative which is deposited without solvents, heat or catalysts, but rather by condensation of a monomer vapor.

    摘要: A stent deployment device (10) includes a catheter (12), a stent (14) positioned on the catheter (12), and a sleeve (16) carried on the catheter (12). The sleeve (16) has a portion (18) extending fully over and containing the stent (14). The stent deployment device (10) also includes a mechanism (20) for splitting at least the portion (18) of the sleeve (16) extending over the stent (14) and, preferably, for splitting the entire sleeve (16). Splitting of the sleeve portion (18) permits expansion of the stent (14). The mechanism (20) can include an inflatable, nondistending balloon (22) carried on the catheter (12), the stent (14) and the sleeve portion (18) being positioned over the balloon (22). The stent (14) can be self-expanding or can be expanded by the balloon (22) itself. Alternatively, the mechanism (20) can include a bulbous end (24) on the catheter (12). Longitudinal movement of the bulbous catheter end (24) with respect to the sleeve (16) splits at least the sleeve portion (18), permitting expansion of the stent (14). As further alternatives, the mechanism (20) can include a garrote (66) connected to the sleeve or a partial segment (62) of the sleeve (16) folded back alongside the stent (14). The sleeve (16) can be the same length as the catheter (12) or can be shorter than the catheter (12). In the former case, the mechanism (20) can include a pair of graspable wings (56) for splitting the full length of the sleeve (16). It is preferred that at least the portion (18) of the sleeve (16) extending over the stent (14) includes a longitudinally extending structure 46 for ensuring that the sleeve portion (18) will in fact split upon operation of the mechanism (20).

    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.
