TARGET IDENTIFICATION TOOL FOR INTRA-LUMENAL LOCALIZATION

摘要

An intralumenal marker that includes an atraumatic anchoring portion that allows the marker to be fixed within a body lumen, such as an airway, without risk of migration. The anchoring portion may be an elongate body that reassumes a relaxed, coiled configuration after being delivered from a catheter. A body portion is attached to the anchoring portion and provides a function such as radiopaque marking, drug delivery, illumination, or the like.
