Abstract: An implant to fill a hole in tissue, such as bone tissue, comprising a first portion that is insertable through the hole when in a first compressed position, wherein the first portion cannot pass through the hole when in a first deployed position; and a second portion that cannot pass through the hole when in the second deployed position. The first and second portions of the implant can be deployed independently. Therefore, in operation, it is possible to insert the first portion of the implant through the hole when in the first compressed position, deploying the first portion to transition it to the first deployed position while the second portion remains in the second compressed position, and then deploying the second portion to transition it to the second deployed position. The devices and methods may be used, for example, in transsphenoidal or other orthopedic surgeries involving bone tissue.
