Patent ID: 8795305

Claim:
A medical device for securing a vascular device for removal from a body, the medical device comprising: a shaft having a flexibility to navigate through tortuous anatomy, the shaft having a distal portion and a proximal portion and a lumen extending therethrough; and an eversible cover having a fixed section affixed near an end of the distal portion of the shaft, a free section extending in a proximal direction from the fixed section and an eversible cover wall extending from the fixed section to the free section, where on deployment in a vessel the eversible cover wall expands against a vessel wall and is fluid permeable to permit flow therethrough, the eversible cover being axially compliant such that when the vascular device retrieval device is positioned through the shaft lumen and moved in a proximal direction, the friction of the eversible cover against the vessel wall causes the eversible cover to completely evert over the vascular device in a conveyor belt type manner allowing for the free section of the eversible cover to be distal to the vascular device; and where the eversible cover wall is configured to expand outward upon deployment in the vessel and to collapse inward after everting and compress an obstruction.
