STRIDE Study
Firstline use of the Indigo® Aspiration System for Acute Limb Ischemia patients resulted in low 30-day amputation rates, low peri-procedural complications, and high rates of technical success.
Prospective, Single-Arm
119 Patients
16 International Sites
Lower Extremity Acute Limb Ischemia (LE-ALI)
-
To collect safety and performance data with the Indigo Aspiration System in a patient population with lower extremity acute limb ischemia (LE-ALI)
-
In the STRIDE study, aspiration thrombectomy with the Indigo System provided a safe and effective endovascular treatment for LE-ALI patients, resulting in a high rate (98.2%) of successful limb salvage at 30 days, with few peri-procedural complications.
Now published in the Journal of Vascular Surgery
Clinical Trials
30-day Results:
98.2% Target limb salvage rate at 30 days post procedure
3.4% Mortality at 30 days
22 min Median Indigo Aspiration Time
0.8% Device-related SAE
