1. A system, comprising:
a packer sized for placement along a well string to enable formation of a seal at a desired location in a borehole, the packer comprising:
an internal tubing;
a packer mandrel located about the internal tubing and having at least one feedthrough extending longitudinally therethrough from a first axial end of the packer mandrel to a second axial end of the packer mandrel;
a first end connector disposed about the packer mandrel at the first axial end of the packer mandrel;
a second end connector disposed about the packer mandrel at the second axial end of the packer mandrel;
an expandable metal bladder secured around the packer mandrel and coupled to the first end connector and the second end connector; and
a sealing element mounted around the expandable metal bladder and positioned to move into sealing engagement with a surrounding borehole wall when the expandable metal bladder is sufficiently expanded via internal pressure.
