1. A system comprising:
- a cannula comprising a cannula distal end;
an elongate member comprising an elongate member distal end;
a first plate configured to be slidably disposed within the cannula and coupled to the elongate member distal end;
a second plate configured to be slidably disposed within the cannula and coupled to the elongate member distal end; and
a spring disposed between the first and second plates, the spring configured to be at least partly compressed when the first and second plates are within the cannula, and to decompress, at least in part, as at least one of the first and second plates is extended beyond the cannula distal end, thereby increasing a distance between the first and second plates.

Abstract
Systems and methods for providing a cavity in an interior body region are described. In one described method, a spring disposed between a first plate and a second plate is compressed. The compressed spring is inserted into a cannula comprising a cannula distal end. The spring is decompressed, at least in part, once at least one of the first and second plates is inserted beyond the cannula distal end to a treatment area adjacent a tissue. The decompression of the spring increases a distance between the first and second plates.
