1. An apparatus for incising a lesion in a vessel using an expandable device on a guidewire, comprising:
a catheter including a body having a first portion with a guidewire lumen configured to receive the expandable device, and a second portion with a protrusion, the second portion of the body including an arc-shaped pocket defining only a single arc of a circumference of a circle, wherein a remainder of the circumference of the circle remains open, wherein the pocket is adapted for partially circumferentially surrounding the expandable device only on a single portion of a circumference of the expandable device such that a remainder of the circumference of the expandable device is not contacted by the catheter, and the protrusion extends from the second portion of the body and is adapted for incising the lesion upon expansion of the expandable device;
wherein the arc-shaped pocket defines a lateral opening along the second portion, said lateral opening being continuous with a distal-facing opening on a distal end of the second portion.
