Summary

This trial aims to test a system called Thor in adult patients with new calcified lesions in the leg arteries. It wants to find out if the Thor system is safe and effective in treating these lesions.

Who is the study for?
Adults over 18 with new, untreated calcified leg artery blockages (PAD) who can walk on their own or with help from non-motorized devices. They must have a life expectancy over a year and agree to follow the study's rules, including consent form signing and attending follow-up visits.
What is being tested?
The THOR IDE Study is evaluating the safety and effectiveness of the Thor laser atherectomy system in treating newly diagnosed calcified lesions in patients' leg arteries. Participants will be treated with this system and monitored for up to one year.
What are the potential side effects?
While specific side effects are not listed here, typical risks may include discomfort at the treatment site, bleeding, potential damage to surrounding tissues or vessels during the procedure, infection risk post-treatment, and possible allergic reactions.
