Patent attributes
Embodiments of the present disclosure are directed to medical devices, methods, and systems for delivering a medical device to a target site. In one embodiment, a medical device includes a tubular member having a proximal end and a distal end, the tubular member having an expanded configuration and a relaxed configuration. The medical device further includes a tether comprising a first end and a second end, the first end coupled to the proximal end or the distal end of the tubular member. In addition, the medical device includes an engagement member coupled to the second end of the tether and disposed at least partially within the tubular member and between the proximal and distal ends of the tubular member in the relaxed configuration. The engagement member is configured to engage the proximal or distal end of the tubular member, opposite the first end of the tether, upon displacement of the proximal and distal ends of the tubular member towards one another, such that the tubular member is locked in the expanded configuration.
