  • VASCULAR FILTER SYSTEM AND METHOD OF DEPLOYMENT AND RETRIEVAL OF A VASCULAR FILTER
    Publication number: 20230172702
    Abstract: A vascular filter system for deploying a vascular filter utilizes a plurality of tensors that extend radially outward from a deployment sheath. The ends of the tensors are coupled with an attachment ring of the vascular filter and a plurality of attachment barbs are coupled with the attachment ring for securing the filter to the vessel wall. A method for retrieving the vascular filter from the vessel utilizes a reverse curve catheter, a guidewire that extends therethrough and an intravascular snare. The guidewire is advanced around the filter and into the snare which secures the guidewire around the filter for retrieval. A vessel distention device utilizes one or more distention tensors having a distention feature on the extended end, such as a blunt tip, to press on the inside vessel wall. The distention tensors extend out radially from a sheath to press on the vessel wall.
