Embolectomy devices and methods
First Claim
1. An embolectomy device for removing an obstruction from a vascular site, comprising:
- a tubular body having a radially collapsed delivery configuration and a radially expanded deployed configuration, the tubular body comprising a plurality of interconnected primary struts that define a plurality of openings when the tubular body is in the radially expanded deployed configuration, and a plurality of secondary struts having first ends connected to the primary struts and second ends that are releasably constrained on the primary struts when the tubular body is in the radially collapsed delivery configuration,wherein the secondary struts are configured to self-move or are otherwise movable from an aligned configuration, in which the secondary struts are aligned or substantially aligned with respective primary struts, to a non-aligned configuration, in which the first ends of the secondary struts remain connected to the primary struts and the second ends of the secondary struts are released from the primary struts and extend away from the primary struts at least partially into and/or across the openings of the expanded tubular body,such that, when the tubular body is delivered to a targeted vascular site proximate an obstruction, and moved or allowed to self-move from the radially collapsed delivery configuration to the radially expanded deployed configuration by expanding radially into or through the vascular obstruction, the secondary struts move or are otherwise movable from the aligned configuration to the non-aligned configuration to ensnare or encapsulate the vascular obstruction or portions thereof between or within the primary and secondary struts.

Abstract
An embolectomy device includes a tubular body having a plurality of interconnected primary struts that define a plurality of openings when the tubular body is in a radially expanded deployed configuration, and a plurality of secondary struts connected to the primary struts that move from being aligned with the primary struts to a non-aligned configuration in which the secondary struts extend at least partially into and/or across the openings, to thereby ensnare or encapsulate a vascular obstruction within the primary and secondary struts after the tubular body is deployed proximate the obstruction and allowed to expand into or through the obstruction.
