Embodiment Construction

[0043] figure 1 A side view of a thrombectomy catheter 100 according to an embodiment of the present invention is shown. As will be described in detail below, in order to remove a thrombus from a blood vessel, the thrombectomy catheter 100 is configured to generate a pressurized fluid at the distal end. In addition, in order to remove the thrombus with pressurized fluid, a vacuum source (suction) is provided at the distal end of the thrombectomy catheter 100. The thrombectomy catheter 100 generally includes a catheter body 102 that extends from a proximal portion 104 of the catheter to a distal portion 108 of the catheter. The middle portion 106 of the catheter extends between the proximal portion 104 and the distal portion 108 of the catheter. In one embodiment, the distal portion 108 of the catheter body 102 is softer than the proximal portion 104, and this arrangement facilitates the navigation of the catheter body 102 during the vasculature of the subject. The catheter bo...

Abstract

A thrombectomy catheter includes a catheter body extending from a catheter proximal portion to a catheter distal portion and including a catheter intermediate portion, the catheter body includes an aspiration lumen and an infusion lumen extending along the catheter body, wherein the aspiration lumen includes an aspiration orifice open at a distal end of the catheter body.

Description

Technical field [0001] Medical devices, more specifically thrombectomy catheters and methods. Background technique [0002] Thromboectomy is a medical method used to remove blood clots (thrombi) from blood vessels such as arteries or veins. If the thrombus is not removed, it will block the blood flow. One technique for performing thrombectomy is to use a catheter with an injection cavity for breaking up thrombi and a suction cavity for vacuum absorption of thrombus and emboli. [0003] In some examples, a complex catheter system is used to perform thrombectomy operations, and the system is configured to provide multiple high-pressure jets, which can be saline supplied at a pressure of 10,000 psi or greater. Accordingly, a high-pressure pump is required to supply high-pressure fluid. For other medical operations, pumps for high-pressure thrombectomy operations (for example, drug and contrast injection, etc.) are not practical. [0004] In addition, the thrombectomy catheters used ...
