Addressing the final frontier in interventional cardiology

Elumn8 Medical plans to transform the treatment of coronary chronic total occlusions (CTOs) with the Acolyte™ System - the first combination imaging and crossing device designed to simplify the treatment of CTOs.

Chronic total occlusions represent one of the most persistent challenges in cardiology

>250,000

Diagnosed chronic total occlusions (CTOs) by coronary angiogram in the US each year

>1.8M

US Patients living with persistent chest pain, decreased quality of life and reduced exercise capacity due to untreated CTOs 

Minimally-invasive treatment of chronic total occlusions is significantly underpenetrated

CTO-PCI

Endovascular crossing attempts using wires and catheters are performed only in a minority of eligible patients because there are no reliable, effective and easy-to-use tools available

CABG

Highly invasive coronary artery bypass graft (CABG) open-heart surgery is a morbid and costly procedure, yet is still performed almost 10x as often as CTO-PCI in the US every year

Medical Management

1.8M patients in the US live with angina that is medically managed.  80% of patients with a CTO report significant angina despite their medical therapy.  They could potentially benefit from revascularization of the CTO
