The Vascular Tunneling System is designed to create a subcutaneous tunnel for the placement of a vascular graft in both peripheral and AV access applications. While the Tunneler System can be used with a graft that does not feature a Slider Graft Deployment System (GDS). The Tunneler System and its components are made of surgical-grade stainless steel and are designed for multiple reuse when properly maintained. We also offer the option to customize your tunneler in multiple sizes and diameters.
