Methods and devices for preparing and implanting tissue scaffolds
Methods and devices are provided for preparing and implanting tissue scaffolds. Various embodiments of scribing tools are provided that are configured to mark one or more predetermined shapes around a defect site in tissue. The shape or shapes marked in tissue can be used to cut a tissue scaffold having a shape that matches the shape or shapes marked in tissue. In one embodiment, the scribing tool used to mark a shape in tissue can also be used to cut the tissue scaffold.
1. A tissue repair kit, comprising:
a scribing tool configured to form in tissue a circular mark having a predetermined diameter; and
a cutting template device having first and second portions slidably coupled to one another, the first and second portions having a first position in which the first and second portions define a circular cut-out formed therebetween and having a diameter that corresponds to the predetermined diameter, and an expanded position in which the first and second portions define an oblong cut-out formed therebetween and having a major axis length that is adjustable.
2. The kit of claim 1 , wherein the first and second portions in the first position define a plurality of circular cut-outs formed therebetween, each of the plurality of circular cut-outs having a different diameter.
3. The kit of claim 2 , further comprising a plurality of scribing tools, each of the plurality of scribing tools configured to form in tissue a circular mark having a predetermined diameter corresponding to one of the diameters of the plurality of circular cut-outs.
4. The kit of claim 1 , wherein the first and second portions in the expanded position define a plurality of oblong cut-outs formed therebetween, each of the plurality of oblong cut-outs having a major axis length that is adjustable.
