Embodiment Construction

[0056] figure 1 An example embodiment of a thrombectomy device 100 is shown. Such devices can be delivered percutaneously and through the patient's vasculature to a thrombus site, such as a neurovascular, cardiovascular, or peripheral venous thrombosis site. The thrombectomy device 10 can be used in both antegrade and retrograde applications.

[0057] The exemplary thrombectomy device 10 generally includes a support wire 15 and a distal device body 12 that includes three (3) major components: (i) a tether assembly 20; (ii) a body frame 30; and (iii) ) filter bag 40. Central collar 18 can couple tie down assembly 20 to support wire 15 . The distal device body is collapsible so that it can be received within the catheter lumen for delivery across the patient's vasculature to the site of the thrombus (eg, see Figure 2D with Figure 2E ). At the thrombus site, the thrombectomy device 10 can be deployed outwardly from the distal tip of the delivery catheter, at which point t...

Abstract

A thrombus treatment device includes a support wire, a body frame portion that is disposed about an axis defined by the support wire, one or more tethers that each have a first end and a second end, and a filter element extending from the body frame portion. Each of the one or more tethers is attached at its first end to the body frame portion, and at its second end to a collar that couples the second end of each of the multiple tethers to the support wire. When the collar is positioned substantially within a region interior of the body frame portion, a rotational actuation of the support wire causes a swiveling motion of the one or more tethers.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 683,043, filed August 14, 2012. The disclosure of the earlier application is considered a part of the disclosure of the present application and is incorporated by reference into the disclosure of the present application. This application also incorporates by reference the publication of a co-pending application entitled "DEVICES AND SYSTEMS FOR THROMBUS TREATMENT" filed March 13, 2013 (Attorney Case No. MP / 426A). technical field [0003] The present disclosure relates to devices, systems and methods for treating thrombus. Background technique [0004] Blood clot formation or "thrombosis" underlies a number of serious diseases such as ischemic stroke, myocardial infarction (heart attack) and deep vein thrombosis (DVT). Blood clots, or "thrombi," form inside blood vessels and block the flow of blood through the circulatory system, depriving tissues ...
