Seal apparatus and methods of use |
| abstract |
A seal apparatus and method of use is described. The apparatus comprises a seal assembly comprising a plurality of seal elements assembled together to form a ring structure around a longitudinal axis. The ring structure is operable to be moved between an expanded condition and a collapsed condition by movement of the plurality of seal elements. The plurality of seal elements is operable to be moved between the expanded and collapsed conditions by sliding with respect to one another along respective contact surfaces. Each of the plurality of seal elements is each formed from a compliant, compressible or resilient material. |
