The device further includes a plurality of connector struts attached at a proximal end of the anchor stent, the connector struts coalescing to form a strut tip. A guide device, such as a guidewire, is attached to the anchor stent at the strut tip and may be used to guide the anchor stent into the arteries or other vessels and toward a target treatment site. | 2022-03-10 |
