• Method of IVUS analysis of calcium reduction. Pre-treatment IVUS (A), and the corresponding post-atherectomy IVUS (B). • The analysis sequence is shown at the bottom. • After identifying and matching the slices with calcium reduction, the lumen borders for both pretreatment (blue circle: lumen area=5.0 mm2) (C) and post-atherectomy images (green circle: lumen area=19.5 mm2 ) were contoured; and the two were overlaid. By comparing the two contours to the visual assessment of plaque, lumen gain (14.5 mm2) could be attributed automatically.
Early outcomes of novel Temren atherectomy device combined with drug-coated balloon angioplasty for treatment of femoropopliteal lesions The Kaplan–Meier estimator estimated the rate of freedom from target lesion revascularization (TLR) estimated that the was 92.3%. Combined use of Temren RA with adjunctive DCB is a safe and effective method with high rates of primary patency and freedom from TLR and low rates of complication in the treatment of femoropopliteal lesions.

TemREN represents a front-cutting atherectomy device engineered to mechanically debulk and clear plaque within peripheral arteries—especially in challenging PAD (Peripheral Arterial Disease) lesions. By combining low-profile design, direct lesion access, and reduced vessel trauma, TemREN is poised to enhance both efficacy and procedural confidence in the endovascular management of systemic atherosclerosis.
Front Cutter
- Direct Lesion Debulking: The front-cutting mechanism addresses atherosclerotic tissue at the lesion core, reducing the need for nosecone passage prior to cutting.
- Minimized Vessel Trauma: By precise plaque shaving rather than forceful pushing, the cutter design aims to lower shear stress or vessel dissection risk.
Low-Profile, Over-the-Wire Catheter
- Enhanced Deliverability: A streamlined catheter shaft navigates through tortuous pathways without unnecessary friction, improving trackability and pushability.
- Wire Guidance: The over-the-wire approach allows stable lesion crossing, facilitating accurate lesion engagement and device alignment.
Reduced Need for Stents
- Mechanical Atheromatous Removal: Atherectomy can diminish plaque burden while preserving or maximizing native vessel patency, potentially limiting adjunctive stenting.
- Optimized Physiologic Remodeling: By clearing plaque from the lumen, flow dynamics are restored with lower reliance on metallic implants.
Versatile Indications in PAD
- Femoral, Popliteal, and Infrapopliteal Vessels: Suitable for a range of peripheral segments typically subjected to high shear stress from stenting or angioplasty alone.
- Adjunct to Balloon Angioplasty: Enhances the efficacy of subsequent balloon dilation or drug delivery.
