1. An extractor comprising;
- a host structure having an elongate axis;
a plurality of expandable members connected to the host structure arrayed radially around the elongate axis;
a slide mechanism, including;
a first collar connected to the host structure and to a first end of the expandable members and slidable in the direction of the elongate axis; and
a second collar located inside the host structure and connected to a second end of the expandable members; and
a circumferential member having a first peripheral edge and a second peripheral edge that are both of approximately equal circumference encircling a middle portion of the expandable members, where the circumferential member with its first and second peripheral edges is coupled to the middle portion of the expandable members such that the circumferential member maintains a generally uniform lateral spacing between the plurality of expandable members.

Abstract
Methods, devices, and systems for extracting vessel occluding material are provided. An embodiment of a vessel occluding material extractor includes a host structure, a plurality of expandable members, a slide mechanism, and a circumferential member. The host structure has an elongate axis. The expandable members are connected to the host structure arrayed radially around the elongate axis. The slide mechanism is connected to the expandable members and adjacent the host structure, and is slidable in the direction of the elongate axis. The circumferential member is connected to the expandable members between the connection of the slide mechanism and the host structure to the expandable members.
