| 1. A catheter comprising:
a handle comprising:
a housing having a proximal end, a distal end, and a longitudinal axis that extends from the proximal end of the housing to
the distal end of the housing;
a cable, disposed in the housing, that extends through the proximal end of the housing, a portion of the cable that is disposed
in the housing being movable, under compression, in a first direction that is substantially aligned with the longitudinal
axis of the housing; and
a guide, disposed in the housing, adapted to prevent the portion of the cable from moving in a second direction that is transverse
to the first direction when the portion of the cable is moved in the first direction; and
an elongated shaft, a proximal end of the elongated shaft being attached to the distal end of the housing, wherein the cable
extends through the distal end of the housing and into the elongated shaft;
wherein a distal end of the elongated shaft is coupled to a conductive braided mesh; and
wherein a distal end of the cable is coupled to a distal end of the braided mesh, and wherein the distal end of the braided
mesh is movable distally in response to movement of the portion of the cable in the first direction.
