Peripheral Artery Disease study: Thor laser atherectomy
Official title The THOR IDE Study
ClinicalTrials.gov ID: NCT05916950
What this study is testing
- What it's testing
- The study will find out if the Thor system is safe and works to treat new calcified lesions in leg arteries of people with peripheral artery disease.
- Who it's for
- Adults 18 years or older with newly diagnosed, untreated calcified blockages in leg arteries.
- What's involved
- Participants will receive the Thor system treatment and have follow‑up visits after discharge, at 30 days, 6 months, and 12 months.
- Time commitment
- The study lasts about one year with visits at discharge, 30 days, 6 months, and 12 months.
- Time commitment: about 12 months

- Other surgical or endovascular procedure in the target limb that occurred within 14 days prior to index procedure or is planned on target limb for within 30 days following index procedure, with the exception of...
- Currently participating in any investigational device or drug clinical trial that, in the opinion of the investigator, will interfere with the conduct of the current study
- Subject has significant stenosis (\>50% stenosis) or occlusion of inflow tract before target treatment zone (e.g. iliac or common femoral) not successfully treated.
- Subject requires treatment of a peripheral lesion on the ipsilateral limb distal to the target site at the time of the index procedure.
