Study summary

The purpose of this post-market surveillance study will be to evaluate the real-world use of the DETOUR System in treated patients with symptomatic femoropopliteal lesions from 200 mm to 460 mm in length with chronic total occlusions (100 mm to 425 mm) or diffuse stenosis > 70% who may be considered suboptimal candidates for surgical or alternative endovascular treatments.

Read the detailed description

A maximum of 450 subjects will be enrolled with a target study population of at least 200 evaluable female and 200 evaluable male participants at the 12-month post-procedure follow-up visit. A maximum of 200 US sites. Sites will be selected that participate or will participate in the VQI PVI Registry. Follow up visits/assessments will be completed at 1, 12, 24-, 36-, 48-, and 60-months post-procedure. Study enrollment is expected to conclude over 4 years. Follow up data at 1 year is expected to conclude in 5 years from enrollment, with 5-year follow up expected to conclude in 9 years from enrollment.

Study population

Patients with symptomatic femoropopliteal lesions from 200 mm to 460 mm in length with chronic total occlusions (100 mm to 425 mm) or diffuse stenosis > 70% who may be considered suboptimal candidates for surgical or alternative endovascular treatments.

Groups and cohorts

  • As Treated

    All patients that have received the therapy; patients treated within and outside the IFU criteria subgroups; male and female subgroups; and duplex imaging subgroups for arterial and venous observations.

    Device: DETOUR System

  • Imaging Cohort

    Sites that are performing (arterial and venous) duplex ultrasound assessments according to the institution's standard practice will be asked to participate in the DUS imaging cohort. The Imaging sub-study will consist of 55 female and 55 male subjects from these sites. Duplex imaging at 1-, 12-, 24-, and 36-months post-procedure will be collected to assess the endpoints of graft patency and venous thrombus within the vein containing the graft (n=110).

    Device: DETOUR System

What researchers measure

Primary outcomes

  1. Freedom from CD-TLR

    Primary Effectiveness outcome is patency as defined as Freedom from Clinical Driven Target Lesion Revascularization (CD-TLR)

    Time frame: 1 Year

  2. Freedom from MAE

    Primary Safety outcome is freedom from a major adverse event (MAE) at 30 days post-procedure defined as any occurrence of the following events: Death, Clinically-Driven Target Lesion Revascularization (CD-TLR), and/or Major Amputation of the Treated Limb.

    Time frame: 30 Days

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2023 (actual). Primary completion is estimated for Jun 2028, 56 months after the start.

Of 58 industry-sponsored observational studies under Peripheral Arterial Disease, half reached primary completion within 31 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 39. This study's planned 56 months is above that.

Counting every sponsor, half of 196 studies reached it within 36 months; a quarter within 22 and three quarters within 73.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 12, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
