A downhole method comprising:
- running an apparatus comprising a member and a fusible part into a bore with the member maintained in a retracted configuration by the fusible part;
- locating the tool at a desired location in the bore, and
- heating the fusible part and thereby reconfiguring the member to an extended configuration in which the member engages a wall of the bore.
A downhole apparatus comprising:
- a body;
- a member mounted on the body, the member having an initial retracted configuration and an extended configuration in which the member extends radially from the body, and
- a fusible part for maintaining the member in the retracted configuration, whereby heating of the fusible part permits reconfiguration of the member from the retracted configuration to the extended configuration.
