A method of conducting biological materials in soft tissue includes inserting an elongated conduit device into the soft tissue and through a defect in the soft tissue, and conducting biological materials along at least one longitudinal channel defined on an outer surface of the conduit device into the soft tissue. The conduit device is externally threaded.

A method of conducting biological materials in meniscal tissue, the method comprising: providing a conduit device having a first end and a second end and an externally threaded elongated body extending from the first end to the second end along a longitudinal axis of the conduit device, the elong
1. A method of conducting biological materials in meniscal tissue, the method comprising: providing a conduit device having a first end and a second end and an externally threaded elongated body extending from the first end to the second end along a longitudinal axis of the conduit device, the elongated body having a plurality of external longitudinal channels, each longitudinal channel extending from the first end to the second end along the longitudinal axis, each longitudinal channel being open to an outer surface of the elongated body and having a keyhole-shaped cross-section with a substantially circular portion and a slot-like opening to the outer surface of the elongated body, each slot-like opening being narrower that a width of each circular portion;implanting the conduit device through the meniscal tissue such that each longitudinal channel extends between a first area of the meniscal tissue having a first vascularity and a second area of the meniscal tissue having a second vascularity different from the first vascularity;anddelivering via an external cannula biological materials from the first area to the second area along and within the circular portion of each longitudinal channel from the first end toward the second end of the conduit device. 2. The method of claim 1, further comprising coupling the conduit device to a tissue fixation device. 3. The method of claim 2, wherein coupling the conduit device to a tissue fixation device includes forming a flexible strand loop between the conduit device and the fixation device. 4. The method of claim 3, wherein the loop passes through an internal longitudinal bore of the conduit device. 5. The method of claim 3, wherein the loop passes through one of the longitudinal channels of the conduit device. 6. The method of claim 1, further comprising tenting the meniscal tissue over the slot-like openings of the longitudinal channels without obstructing the circular portion of the longitudinal channels. 7. The method of claim 1, further comprising: delivering biological materials to each longitudinal channel during or after implantation. 8. The method of claim 1, further comprising: attaching biological materials to each longitudinal channel before implanting the conduit device. 9. A method of conducting biological materials in meniscal tissue, the method comprising: providing a conduit device having a first end, a second end, a longitudinal axis and a longitudinal bore between the first end the second end;passing a suture strand through the longitudinal bore of the conduit device, the conduit device having a plurality of external longitudinal channels not communicating with the longitudinal bore;coupling the suture strand with a fixation device, the fixation device inserted through a meniscal defect;returning the suture strand through the longitudinal bore of the conduit device to form a suture loop;implanting the conduit device through the meniscal defect such that each longitudinal channel extends between a first area having a first vascularity and a second area having a second vascularity different from the first vascularity;delivering, via an external cannula, biological materials from the first area to the second area along and within the longitudinal channels from the first end toward the second end of each longitudinal channel; andsecuring the suture loop with a knot. 10. The method of claim 9, wherein delivering biological materials from the first area to the second area through the longitudinal channels comprises delivering biological materials through a substantially circular portion of a cross-section of each of the longitudinal channels, the circular portion leading to a slot narrower than the circular portion and extending to an outer surface of the conduit device. 11. The method of claim 10, further comprising tenting the meniscal tissue over the slots of the cross-sections of the corresponding longitudinal channels without obstructing the circular portion of the longitudinal channels. 12. The method of claim 9, wherein delivering biological materials from the first area to the second area through the longitudinal channels comprises delivering biological materials through a substantially V-shaped cross-section of each of the longitudinal channels. 13. The method of claim 9, wherein implanting the conduit device through the meniscal defect comprises positioning the conduit device to span a meniscal tear. 14. The method of claim 13, further comprising passing the suture strand through a second fixation device and a second conduit device; andclosing the meniscal tear.
