Disclosed herein are devices for mechanically removing clot and/or other material from implants implanted in the vasculature of a patient, and associated systems and methods. In some embodiments, a system for removing clot material from an implant—such as a stent—includes a clot treatment device configured to be deployed within the stent, a handle, and a first elongate member and a second elongate member coupling the clot treatment device to the handle. The first elongate member couples a first end portion of the clot treatment device to the handle, and the second elongate member couples a second end portion of the clot treatment device to an actuator of the handle. Actuation of the actuator is configured to move the second elongate member relative to the first elongate member to move the first and second end portions toward one another to radially expand the clot treatment device.

Devices for removing clot material from intravascularly implanted devices, and associated systems and methods

Methods of braiding using a braiding mechanism are described. The braiding mechanism includes a disc defining a plane and a circumferential edge, a mandrel extending from a center of the disc that is adapted to hold a plurality of filaments extending radially from the mandrel toward the circumferential edge of the disc, a plurality of catch mechanisms positioned circumferentially around the edge of the disc, a plurality of actuators adapted to move the plurality of catch mechanisms in a substantially radial direction relative to the circumferential edge of the disc, and a plurality of filaments extending radially from the mandrel towards circumferential edge of the disc. A middle portion of each filament of the plurality of filaments contacts an end of the mandrel.

Braiding mechanism and methods of use

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 having a plurality of first clot engagement members and second clot engagement members positioned about the circumference of a distal portion of the support member. In an undeployed state, individual first clot engagement members can be linear and have a first length, and individual second clot engagement members can be linear and have a second length that is less than the first length. The clot engagement members can be configured to penetrate clot material along an arcuate path and hold clot material to the clot treatment device.

Methods and apparatus for treating embolism

Methods and devices for treatment of a patient's cerebral aneurysm is described. The device includes a permeable shell having a radially constrained elongated state configured for delivery within a catheter lumen, an expanded state with a longitudinally shortened configuration relative to the radially constrained state, and a plurality of elongate filaments that are woven together to form a mesh. The proximal ends of each of the plurality of filaments are gathered by a proximal hub and the distal ends of each of the plurality of filaments are gathered by a distal hub. The proximal portion of the permeable shell includes a swellable polymer. The method includes advancing the implant in a microcatheter to a region of interest in the cerebral vasculature, deploying the implant within the cerebral aneurysm, and withdrawing the microcatheter from the region of interest after deploying the implant.
