The Tack Endovascular System is a first-of-its-kind dissection repair device that is purpose-built to provide precision treatment of peripheral arterial dissections following balloon angioplasty, in either above- or below-the-knee therapeutic interventions.Tack® implants feature Adaptive Sizing™ which allows the implant(s) to adapt to tapering vessels while maintaining a relatively constant radial force. This means that a single size Tack implant can be used across a wide range of vessel diameters. The systems are pre-loaded with 4 (BTK) or 6 (ATK) self-expanding nitinol Tack implants that can be deployed to treat multiple dissections using a single catheter and leave behind >70% less metal than stents.1
