Problems solved by technology

When doctors manually operate the system, total blood loss can reach unacceptable levels before enough clots are removed
Additionally, reliably identifying whether the tip of the catheter is in contact with a clot or is undesirably drawing healthy clot-free blood is an important issue, and such manual control is suboptimal

Embodiment Construction

[0052] Some embodiments of the invention of the present application are described below. In the interest of clarity, not all features of every actual implementation are described in this specification. During the development of an actual device, some modifications may be made so that the embodiments still fall within the scope of the present invention.

[0053] refer to Figure 2 to Figure 6 , a vacuum system 40 of the type useful for the apparatus and method for controlled clot aspiration of the present invention will be described. The vacuum system 40 includes a vacuum console 42 and a blood / clot collection tank 44 . Vacuum console 42 includes a housing having a recess 48 shaped to removably receive collection canister 44 as will be described in greater detail below.

[0054] refer to Figure 3A to Figure 3C , shows the vacuum console 42 with the vacuum tank 44 removed. A post 50 forming a continuation of the outer surface or wall of the housing 46 is formed within the ...

Abstract

A vacuum aspiration control system for use with a vacuum source and an aspiration catheter includes a connecting tube configured to connect the vacuum source with a lumen of an aspiration catheter. Anon-off valve is operatively coupled to the connecting tube, and a sensing unit is configured to detect flow within the connecting tube and provide a signal representative of flow. A controller receives the signal to decide whether to open or close the valve. The controller may automatically close the valve to stop flow when flow through the connecting tube is unrestricted, or according to a predetermined timing sequence. The controller can further periodically open a closed valve to determine whether flow has entered an acceptable range. The controller can still further engage pulsed aspiration with a pressure manipulation assembly when flow is restricted or occluded.
