Embodiment Construction

[0040] The examples disclosed herein may generally comprise a control device or a suction device for use with a hemostatic valve, compared to some conventional systems, the device or apparatus that allows for easier blood flow rate changes during the suction treatment physician within the vessel. Suction control means may comprise a suction blood flow path control valve and for moving the control valve to regulate the flow rate through the flow path of the joint. At a flow rate control valve can control the flow reversal at the treatment site. For example, blood clots around the reverse flow can be varied during operation of the thrombus by surgery suction control device.

[0041] Suction control device may be positioned at various locations, and have various configurations in order to achieve control of the joint compared to conventional systems easier to use. For example, the suction control device may be connected to a separate hemostatic valve assembly side port, the hemostasi...

Abstract

The invention discloses an aspiration control valve. An aspiration control device can have an aspiration control valve and a switch, button, slider, trigger, grip, lever, rotating wheel, rotating valve, handle or other interface for resizing the aspiration control valve. The aspiration control interface can be conveniently positioned and configured to be manipulated while simultaneously stabilizing a catheter and / or retracting an elongated member. The aspiration control device can be integrated with a hemostasis valve, integrated with a wire gripping device, and / or attached to an inlet, outlet, hose, pump, or syringe in series with an aspiration flow path.

Description

Technical field [0001] The present invention generally relates to intravascular medical, and more particularly, to a suction adjustment during surgery thrombus blood flow. Background technique [0002] In the blood vessels during a medical, slowing or reversal of blood flow in the treatment site of the patient's body may be advantageous. For example, embolectomy, the physician can use a syringe or a vacuum pump to obtain a reverse blood flow to assist with the movement of a blood clot or thrombus stentriever and removed or directly to the suction passage intermediate conduit or conduits. The proximal end of the syringe or pump may be connected to the intermediate catheter or guiding catheter (e.g., balloon catheter guide), and the vacuum may be communicated through the lumen of the catheter distal tip of the catheter. Syringe and a vacuum pump is typically connected to the "rotating hemostasis valve" side arms, the "rotating hemostatic valve" attached to the intermediate guide ca...
