- (a) preparing a body channel to receive a wire centering sheath device;
- (b) inserting a wire centering sheath device within a body channel, the device comprising a shaft, the shaft having a proximal end, a distal end, a sidewall, at least two slots forming at least two voids in the sidewall, and at least two centering wires connected to the shaft and disposed adjacent to the at least two slots, wherein the shaft includes a shaft inner lumen running from the proximal end to the distal end;
- and a rod adapted for inserting into the proximal end of the shaft, the rod having a distal end configured to engage within the shaft inner lumen;
- (c) deploying the at least two centering wires by axially moving the rod within the shaft inner lumen so as to contact the at least two centering wires and urge the at least two centering wires to extend into the at least two voids and contact the body channel, wherein the wire centering sheath device is centered within the body channel.
