1. A snare device for use in a vasculature, comprising:
an elongate member extending axially between a proximal end and a distal end, the elongate member configured to extend exterior of the vasculature in use; and a self-expanding body configured to engage material found in the vasculature, the body having a proximal end and a distal end, the body comprising a first configuration comprising a compressed diameter that permits intraluminal delivery of the body through the vasculature and a second configuration comprising an expanded diameter for deployment in the vasculature to displace and/or remove the material found in the vasculature; wherein the proximal end of the body is fixed to the distal end of the elongate member, the body and elongate member are configured such that, when the body is in the second configuration and deployed in the vasculature, proximal translation of the elongate member results in proximal translation of body, the body comprises a plurality of interconnected struts that define a snare pattern, in the expanded configuration said interconnected struts define an axially extending substantially tubular-shaped section between the proximal and distal ends of the body, the interconnected struts define a plurality of apertures longitudinally and circumferentially along the snare pattern, each aperture includes curved members shared by adjacent circumferential and longitudinal apertures, the proximal end of the body is fixed to the elongate member via two connectors that diverge radially outwardly in the distal direction from a point of attachment to the elongate member, the two connectors each having a proximal end and a distal end, the distal ends of the two connectors are each connected to a different aperture in the snare pattern, and the snare pattern originates at and extends distally from the distal ends of the two connectors. |
