Abstract

A device for sealing an aperture in a tissue includes: an implant configured to seal the aperture when positioned adjacent to the aperture; and a delivery shaft configured to engage the implant to allow the implant to be maneuvered into sealing engagement with a distal surface of the tissue, the delivery shaft comprising a retaining sleeve comprising a locking projection engagable with the locking recess of the implant to secure the implant to the delivery shaft, and a release sleeve axially slideable relative to the retaining sleeve between a first axial position in which the release sleeve is configured to maintain locking engagement between the locking recess and the locking projection, and a second axial position in which the release sleeve permits the locking projection to disengage the locking recess.
