Abstract
A device and method for intravascular treatment of an embolism, and particularly a pulmonary embolism, is disclosed herein. One aspect of the present technology, for example, is directed toward a clot treatment device that includes a support member configured to extend through a delivery catheter and a plurality of clot engagement members positioned about the circumference of a distal portion of the support member. The individual clot engagement members can have a first portion and a second portion extending from the first portion, and the first portions can have a proximal region attached to the support member. In the deployed state, the individual second portions can extend from the distal region of one of the first portions and project radially outwardly relative to the support member in a curve that has a proximally extending section which defines a proximally facing concave portion.

20. A method of treating an embolism that at least partially restricts blood flow through a vessel, the method comprising:
-
deploying an embolectomy device within the embolism by penetrating clot material with a plurality of clot engagement members, wherein individual clot engagement members extend into the clot material along an arcuate path that extends radially outward and proximally with respect to the elongated shaft, and then curve radially inwardly, whereby the clot material is held by the clot engagement members; moving the embolectomy device and at least a portion of the embolism along the vessel; and withdrawing the embolectomy device and at least a portion of the embolism from the vessel. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
