Abstract
A device for the local delivery of a substance into a natural tissue conduit in the mammalian body, having a first clement capable of contacting the lumen of the conduit and a second element which overlays first element, a reservoir being formed between the first element and the second element, the interior of the reservoir being capable of fluid communication with the conduit such that a substance placed in the reservoir is delivered into the conduit. Also provided are methods of locally delivering a substance into a natural tissue conduit in the mammalian body utilizing the device of the present invention.
Claims26
A device for the local delivery of a substance into a natural tissue conduit in the mammalian body, comprising:
- a) a first element comprised of a biocompatible material which can be affixed to the conduit and having a first surface, an opposite second surface, and an intermediate porous portion which communicates the second surface with the first surface, wherein the first surface of the porous portion can be placed in fluid communication with the lumen of the conduit;
- and
- b) a second element comprised of a substantially non-porous biocompatible material which overlays the second surface of the first element, a reservoir being formed between the first element and the second element, the interior of the reservoir being capable of fluid communication with the conduit via the porous portion such that a substance in the reservoir is delivered into the conduit.
