Исследование THOR IDE (THOR)
The goal of this clinical trial is to test the Thor system in adult (≥ 18 year old) patients with de novo (new, never treated) calcified lesions in infrainguinal (leg) arteries (peripheral artery disease or PAD).
The main question[s] it aims to answer are:
- Is the Thor system safe in treating these lesions
- Does the Thor system work to treat these lesions
Participants will:
- Receive treatment with the Thor system
- Have follow-up visits at Discharge, 30 days, 6 months, and 12 months

Подробное описание
Up to 30 sites in the U.S. will be selected to do this study.
Patients with pain in their legs when walking and/or resting that is due to lack of blood flow to their legs may be able to join the study. To join the study patients must also have blockages in their leg arteries that meet the study criteria.
Before the Thor procedure, patients will have a screening visit that includes a review of their medical records, questions about their medical history and medications taken for blood thinning or circulation, a physical examination of their legs, a test to check the blood flow in their legs (by checking arm and leg blood pressures), blood tests, and a pregnancy test if they are a female able to have children. Patients will also answer questions about any trouble they have had with walking in the last week and their overall quality of life.
All patients in the study will have treatment with the Thor system. There is no "control group" (a group of patients that receives only standard treatment or receives no treatment at all) in this study. During the procedure, the doctor will take x-ray pictures of the leg arteries. They may also use other treatments such as angioplasty balloons, drug-coated balloons, stents, and filters that collect blood clots, if needed.
Patients treated with the Thor system will be watched until they are ready to go home or up to 24 hours after the procedure if they do not go home right away. Before they go home they will have a test to check the blood flow to their legs (by checking arm and leg blood pressures) and be checked for any adverse events.
Patients will return for visits at 30 days, 6 months, and 12 months after the Thor procedure. At these visits patients will be asked questions about their medical history and medications taken for blood thinning or circulation, have a physical examination of their legs, have a test to check the blood flow in their treated leg (by checking arm and leg blood pressures), have an ultrasound of their treated leg, and be checked for any adverse events. Patients will also answer questions about any trouble they have had with walking in the last week and their overall quality of life.
It will take up to 24 months (2 years) to enroll all of the patients in the study. Patients who join the study will be in the study for about 12 months (1 year) and will have all of the visits with their doctor that they would normally have for their PAD.

Defined as the change in SF-36 score at 30 days compared to the baseline (Screening) value. The SF-36 is a patient-reported survey of patient health.

Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability. |

Defined as the change in SF-36 score at 6 months compared to the baseline (Screening) value. The SF-36 is a patient-reported survey of patient health. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability. |

Change in Walking Impairment Questionnaire (WIQ) score, 30 days
Временное ограничение: 30 days
|
Defined as the change in WIQ score at 30 days compared to the baseline (Screening) value. The WIQ measures self-reported walking impairment, walking distance, walking speed, and stair-climbing ability. In the WIQ there are 21 questions to rate the degree of difficulty with the walking and stair climbing elements. The response for each question is on a 0 to 4 scale, where 0 represents the inability to walk or climb stairs, and 4 represents no difficulty. |
