简要总结
Up to 30 enrolled subjects will be treated. Enrolled subjects will receive Ultherapy® treatments along each length of the spider vein. Follow-up visits will occur at 30 and 60 days post-treatment. Study images will be obtained pre-treatment, immediately post-treatment, and at each follow-up visit.
详细描述
This study is a prospective, single center, clinical trial to be conducted at one clinical site. Enrolled subjects will receive up to three Ultherapy® treatments at a single depth, 14 days apart, using a 10-1.5mm transducer.
