Abstract
Valvulotome devices comprising a cutting edge are provided. Some valvulotome devices incisably engage a venous valve leaflet within a body vessel while at least a portion of the cutting edge is oriented substantially parallel to the longitudinal axis of the valvulotome device. Valvulotome devices are preferably configured to slidably engage a venous valve leaflet upon translation of the valvulotome device along the longitudinal axis of a body vessel. A valvulotome device can further comprise one or more valvulotome arms of variable lengths and dimensions. In some embodiments, the valvulotome device can be self expanding. Embodiments of the invention also provide delivery systems comprising a valvulotome device. The present invention also provides for methods of using a valvulotome device.
