A communications jack includes a housing having a plug aperture, a printed circuit board that is disposed at least partly within the housing, and eight jackwire contacts that are mounted on the printed circuit board and extend into the plug aperture. A shaft is passed through the seat body and connected with the ratchet wheel. The thermal source is operable to generate a predetermined amount of heat, which heats the structure. The device can further include a dissection mechanism, coupled to the elongated member and designed to be positioned about the implanted article, for dissecting a fibrous adhesion about the implanted article. In certain embodiments of the methods of embolization, said composition further comprises a marker molecule, such as a dye, radiopaque, or an MRI-visible compound.
