A stent deployment system includes a wire collection device with a profiled retraction wire and an actuator coupled to a collection spindle. In one aspect, a light source includes a Fabry-Perot laser that is operable to generate multimode laser light, an electroabsorption modulator that is configured to selectively absorb and transmit laser light traveling therethrough, and an optical isolator. Additionally holes along the toes, the bottom, and at the heel allow for increased contact of the user’s foot with the ground, allowing greater feel and balance.
