Medical device for repair of tissue and method for implantation and fixation
First Claim
1. A method for repairing torn tissue of a patient, 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:
- simultaneously inserting a conduit having a longitudinal bore and a portion of a filament disposed within the longitudinal bore through an aperture defined by a tear in the torn tissue, through an insertion point at a face of the tear, and into the tissue, the conduit having a first end and a second end;
positioning the conduit such that the first end is adjacent to the tear;
fixating the tissue with the filament; and
securing the filament.

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.
