The present disclosure describes embodiments for treating a defect in a tissue, the tissue having internal and external surfaces. A device includes a first portion for positioning at one of the internal and external surfaces for applying a treatment force to the defect. In addition, the device has a second portion for applying a counter-force, where the second portion is operable to be positioned so that the counter-force is applied on the other of the internal and external surfaces, away from the defect so as to substantially avoid application of force at the defect. Furthermore, the device includes a coupling member for connecting the inner and outer portions. Methods of using the device are described, for example in an intervertebral disc having a herniation.
