A thrombectomy catheter comprising:
- a catheter body extending from a catheter proximal portion to a catheter distal portion and including a catheter intermediate portion, the catheter body including an aspiration lumen and an infusion lumen extending along the catheter body, the catheter body having an integral homogenous cross-section profile and having a multi-durometer hardness varying along the catheter body's length such that the catheter proximal portion has a relatively high durometer value and the catheter distal portion has a relatively low durometer value, with respect to each other;
- wherein the aspiration lumen includes an aspiration orifice open at a distal end of the catheter body;
