DOUBLE ENDED VASCULAR FILTER

摘要

An implantable vascular filter includes an elongate support element, a first flexible filtering element, a first coupling element at or proximate a first end of the support element for coupling to a retrieval device, and a second coupling element at or proximate a second end of the support element for coupling to a retrieval device. The first flexible filtering element has a first end attached to the support element and a second end movable with respect to the support element and is able to be configured into any of a radially expanded filtering configuration, a first collapsed configuration, and a second collapsed configuration. The first filtering element is biased into the filtering configuration when in a deployed condition, and is collapsible from the filtering configuration into either of the first collapsed configuration or the second collapsed configuration.

1. An implantable vascular filter, including:
an elongate support element having a longitudinal axis; a first flexible filtering element having a first end attached to the support element and a second end movable with respect to the support element, the first filtering element being able to be configured into any of a radially expanded filtering configuration, a first collapsed configuration in which the whole of the first filtering element is collapsed in a first longitudinal direction, and a second collapsed configuration in which the whole of the first filtering element is collapsed in a second longitudinal direction opposite to the first longitudinal direction; the first filtering element being biased into the filtering configuration when in a deployed condition, and being collapsible from the filtering configuration into either of the first collapsed configuration or the second collapsed configuration; a first coupling element at or proximate a first end of the support element for coupling to a retrieval device; and a second coupling element at or proximate a second end of the support element for coupling to a retrieval device; wherein the first filtering element includes a coil.
