  • Publication number: 20090228094
    Abstract: Luminal prostheses comprise scaffolds having coatings adhered to at least a portion of their outer surfaces. The surfaces are modified to enhance binding of the coatings. For example, the surfaces may be microblasted, laser treated, chemically etched, exposed to plasma, or exposed to a corona discharge, allowing a polymeric coating to adhere to the scaffold more tightly than in the absence of the surface modification. The coatings can be used to deliver therapeutic or other agents dispersed therein.

  • Patent number: 7150738
    Abstract: A catheter assembly is provided having a balloon disposed at the distal end thereof. The balloon is capable of being inflated to selectively dilate from a collapsed configuration to an expanded configuration. A syringe assembly is in fluid communication with a delivery lumen of the catheter assembly for allowing a therapeutic substance to be injected into a tissue of a passageway. The syringe assembly includes a portion capable of pivoting from a first position towards a second position when the balloon is being inflated from the collapsed configuration to the expanded configuration. The portion of the syringe assembly is also capable of pivoting from the second position back towards the first position when the balloon is being deflated.
