Abstract
The present invention relates to medical devices for repairing tissue and more specifically to devices which facilitate tissue regeneration and to surgical methods for the implantation and fixation of such devices. In one embodiment, the medical device is an elongate conduit that includes a longitudinal bore extending therethrough to facilitate the transfer of blood from a vascular region of tissue to a tear or damaged area located in an avascular and/or semi-vascular region of tissue. A filament and/or filaments are attached to the conduit and are positioned to secure the conduit and fixate the adjacent tear walls in mutual engagement. In another embodiment, a series of conduits are connected via a filament and/or filaments to facilitate the implantation of multiple conduits.

19. A method for implanting a medical device in tissue, the tissue having a first area of vascularity and a second area of vascularity, the vascularity of the second area being less than the vascularity of the first area, the method comprising the steps of:
-
providing a medical device including an elongate conduit, an anchor, and a filament attached to the conduit and the anchor, the conduit having a first end, a second end, and a wall defining a longitudinal bore, the wall having an exterior surface; inserting the conduit within the tissue; positioning the first end of the conduit adjacent to a face of a tear in the tissue such that the longitudinal bore is in communication with the tear; positioning the second end of the conduit in the first area of vascularity of the tissue; inserting the anchor through the tissue; positioning the anchor against an outer wall of the tissue; and securing the filament. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
