1. A balloon guide catheter comprising:
a catheter shaft having defined longitudinally therein a central lumen and an inflation lumen substantially parallel to the central lumen; the catheter shaft having a braid in a configuration in which the braid is woven about the inflation lumen so that a first portion of the braid extends radially outward relative to the inflation lumen while a second portion of the braid extends radially inward relative to the inflation lumen; and the braid encompassing the central lumen as well;
a balloon disposed about the braid; the balloon has a distal edge and an opposite proximal edge; and
at least one reflow jacket without anything disposed therebetween the at least one reflow jacket and the balloon; the at least one reflow jacket directly covering the proximal and distal edges of the balloon; the at least one reflow jacket made of a material reflowable together with the proximal and distal edges of the balloon into the braid securing the balloon to the catheter shaft; wherein an exposed portion of the balloon is not covered by the at least one reflow jacket.
