Abstract
Devices, systems, and methods for releasing a catheter from an implant may include a catheter comprising first and second elongate elements, first and second elongate element lumens, a tissue anchor lumen, apertures corresponding to each of the lumens, and retaining portions between adjacent apertures. The first elongate element may extend out of its lumen through the first elongate element aperture, across the retaining portion transversely with respect to a longitudinal axis, and towards the second elongate element aperture. The first elongate element may then extend into the second elongate element aperture, loop over the second elongate element, and extend back across the retaining portion and into the first elongate element lumen. In some instances, the second elongate element is retracted to uncouple the first and second elongate elements from each other and to open a channel for the release of tethered tissue anchors.
