The Expandable LeMaitre Valvulotome is designed to be used with a less invasive in situ bypass technique. It is the only self-sizing, self-centering valvulotome available. It cuts valves in the saphenous vein, a vein that runs from the groin to the knee. When used with a semi-closed technique, it helps to prevent wound complications. Valvulotomy can be performed without the need for angioscopy and without changing cutting heads during valve lysis.
- Blade range of 1.8-6.0 mm in a single instrument
- Four recessed blades for cutting valve cusps
- Hoop design helps keep device centered in the vein
- Adjusts to vein diameter automatically
- Teflon sheath for smooth advancement
- Saline injections via built-in irrigation port

Wide blade range: a smaller diameter of 1.8 mm and a blade range of 1.8 to 6.0 mm allows for effective valve cutting without changing blades or instruments.
Four recessed cutting blades: once the Teflon sheath is retracted, four sharp cutting blades are exposed that allow for cutting of valve cusps in a few passes.
Centering hoops: centering hoops help to keep the instrument centered in the vein, allowing for less trauma and more effective valve cutting.
Adjustment to vein diameter: the size of the hoops and blades adjust to the internal diameter of the vein as the valvulotome is being drawn through the vessel.
Teflon sheath: a Teflon sheath covers the blades during insertion, allowing for smooth advancement to the proximal anastomosis.
Irrigation port: saline and anticoagulant solutions can be injected during the procedure through the irrigation port.
