Embodiment Construction

[0024] figure 1 One example of a hybrid system is shown, such as the atherectomy and thrombectomy system 100, configured to perform both atherectomy and thrombectomy procedures at a single location within a blood vessel. refer to figure 1 , the composite system 100 includes a perfusion and aspiration source 102 . For example, the irrigation and suction source 102 includes a metering pump configured, for example, along figure 1 The perfusion line 104 for the catheter 112 shown in FIG. 2 provides a source of perfusion fluid. In addition, irrigation and aspiration source 102 provides aspiration line 106 coupled to conduit 112, for example, through manifold housing 108, which allows for aspiration of particles, for example, upon return to an aspiration destination (e.g., effluent bags, etc.) of particles entrained in the perfusion flow. In one example, negative pressure is applied across suction line 106 by a negative pressure source (eg, metering pump, vacuum pump, vacuum syr...

Abstract

An atherectomy and thrombectomy system includes a catheter body extending between proximal and distal catheter portions. The catheter body includes an aspiration lumen extending therein. An atherectomy assembly is coupled with the distal catheter portion and includes a rotatable cutter. A thrombectomy assembly is coupled with the distal catheter portion. The thrombectomy assembly includes a jet body within the aspiration lumen, and inflow and outflow orifices extending through the catheter body and in communication with the aspiration lumen. In a thrombectomy configuration a cyclical flow is generated by the jet body through the outflow and inflow orifices to hydrodynamically abrade thrombus, the cyclical flow entrains thrombus and delivers thrombus into the aspiration lumen. In the atherectomy configuration the rotatable cutter cuts plaque into plaque particulate, and the cyclical flow of the thrombectomy assembly entrains the particulate and delivers the particulate into the aspiration lumen.

Description

[0001] priority claim [0002] This international application claims priority to U.S. Nonprovisional Patent Application No. 13 / 794,350, filed March 11, 2013, entitled CONSOLIDATED ARTHERECTOMY AND THROMBECTOMY CATHETER, U.S. Nonprovisional Patent Application No. 13 / 794,350 claims priority to U.S. Provisional Patent Application No. 61 / 664,975, filed June 27, 2012, entitled "CONSOLIDATED ATHERECTOMY AND THROMBECTOMY CATHETER," which Both patent applications are hereby incorporated by reference in their entirety. technical field [0003] This document generally relates to, but is not limited to, atherectomy and thrombectomy. Background technique [0004] Atherectomy and thrombectomy are procedures used to remove plaque and thrombus from the vasculature. Plaque is stronger and clings to the vessel wall compared to a thrombus, which is less viscous and easier to remove from the vessel. [0005] In some examples, atherectomy catheters remove plaque from vessel walls by mechanic...
