    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 medical device for localizing a nonpalpable breast lesion. The device includes a tubular introducer needle and a wire guide positioned therein for inserting into a breast to the site of the lesion. The wire guide includes a distal portion having a preformed, resilient helical coil configuration for locking into position about the lesion. The distal portion includes a superelastic metallic alloy for maintaining the helical coil configuration after repeated extensions from and retractions into the needle passageway. The needle is inserted with the wire guide positioned therein into the breast to the site of the lesion and from the distal portion of the needle. The distal end of the needle includes a plurality of indentations for enhancing the ultrasound visualization thereof. As the distal portion of the wire guide emerges from the needle, the acuate distal end of the wire guide cuts into and scribes a helical path about the tissue distal to the lesion. The remainder of the distal portion of the wire guide follows the path scribed by the acuate distal tip and locks about the tissue distal to the lesion. Should the needle and wire guide not be appropriately positioned, the distal portion of the wire guide is retracted into the passageway of the needle to reposition the needle and guide. After desired positioning, the needle is removed with the wire guide remaining in a locked position distally about the lesion for guiding the surgeon to the lesion site during subsequent surgery.

    摘要: The invention provides, in certain aspects, grafting devices deliverable into the body for repairing defects in bodily structure walls. One such grafting device comprises a compliant sheet-form material, and a removable resilient element that is retained in association with the sheet-form material. In some forms, the resilient element is adapted for delivery in its entirety into the body, and thereafter, can be disassociated from the sheet-form material for removal from the body. The sheet-form material may be formed with one or more of a variety of biocompatible materials including some that are naturally derived and some that are non-naturally derived. Illustratively, the sheet-form material may be comprised of a remodelable, angiogenic material, for example, a remodelable extracellular matrix (ECM) material. In additional embodiments, the invention provides methods and apparatuses for delivering these and other inventive grafting device into the body.
