Vascular graft tunneller

Vascular graft tunnellers are surgical instruments usually made of stainless steel, designed with either flexible or rigid rods having handles that taper to a rod with a button or acorn on the distal tip, or ring-handled instruments with extended slightly curved blades with a pivot point near the distal end, used to tunnel along vascular tissue planes to create a connecting channel. These devices are used to create subcutaneous tunnels to facilitate the placement of lead assemblies connected to implantable pulse generators and vascular access devices.
