Device Overview

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

High-Precision Delivery System

  • Standard over-the-wire delivery system
  • Design permits accurate (≤ 1mm) Tack implant deployment

INTENDED USE: The Tack Endovascular System (6F) is intended for use in the superficial femoral and proximal popliteal arteries ranging in diameter from 3.5mm to 6.0mm for the repair of post percutaneous transluminal balloon angioplasty (PTA) dissection(s).

CONTRAINDICATIONS FOR USE: The Tack Endovascular System is contraindicated for the following:
1. Patients with residual stenosis in the treated segment equal to or greater than 30% after PTA.
2. Tortuous vascular anatomy significant enough to prevent safe introduction and passage of the device.
3. Patients with a known hypersensitivity to nickel titanium alloy (Nitinol).
4. Patients unable to receive standard medication used for interventional procedures such as anticoagulants, contrast agents and antiplatelet therapy.
Prior to using the Tack Endovascular System, please review the Instructions for Use for a complete listing of indications, contraindications, warnings, precautions, potential adverse events and directions for use.
