The aim of this clinical trial is to learn if the resorbable scaffold can be successfully implanted in below-the-knee arteries and help to restore the blood flow in diseased vessels. The main questions which will be addressed in this study are:
* Is the implantation of the scaffold safe and easy?
* Does the scaffold dissolve in a reasonable time period?
* Can the stent help to fix intervention-derived vessel injuries such as dissection or recoil? The scaffold will be implanted in patients with critical limb-threatening ischemia which were initially treated with balloon catheters to restore blood flow and where a vessel segment needs additional stabilisation. The scaffold will be implanted during the normal interventional procedure. All 10 patients enrolled into this study will receive at least one scaffold. There is no control group.
The patients will be monitored for their wellbeing after 30 days as well as after 6 and 12 months. The status of the treated vessels will be examined using a non-invasive ultrasound method.
