Embodiment Construction

[0066]FIG. 1 is a plan view of the visible components of a miniature flexible thrombectomy catheter 10, the present invention, including a one-piece manifold 12 having multiple structures extending therefrom or attached thereto and including a configured catheter tube 14 and other components as described herein. Preferably, the catheter tube 14 includes a hydrophilic coating to enhance deliverability along the vasculature or other structure. The visible portion of the one-piece manifold 12 includes a central tubular body 16, a threaded exhaust branch 18, and a high pressure connection branch 20 extending angularly from the central tubular body 16, a cavity body 22 extending proximally from the central tubular body 16 and partially shown and extending distally from the central tubular body 16, and a threaded connection port 24. The proximal end of the catheter tube 14 secures to the manifold 12 by the use of a Luer fitting 26 accommodated by the threaded connection port 24. The proxi...

Abstract

The present invention pertains to a miniature flexible thrombectomy catheter having one or more flexible miniature noncollapsing tubular portions including pushable and torqueable structure for introduction into the smaller vessels in neurovascular regions. A jet body having an arcuate fluid jet emanator is incorporated in order to minimize size at the distal portion of a minimally sized catheter tube.
