Described here are methods, devices and kits for locating tissue and/or forming one or more tracts in tissue. In some variations, tissue may be located (e.g., using one or more optical sensors, ultrasound sensors, thermal sensors, or the like) and one or more tracts may be formed through the tissue after it has been located. In certain variations, the same device may be used both to locate tissue and to form one or more tracts in the tissue. In some variations, a tissue-piercing member for forming one or more tracts in tissue may comprise a first elongated portion and a second elongated portion, and an angle therebetween. |
