摘要：
Embodiments are described for creating and closing tissue access ports, such as transapical access ports, which involve placement of an introducer across the subject tissue structure, and deployment of a controllable port closure device assembly configured to remain in place with a ratcheting mechanism, and to hold the tissue surrounding the previous access port location closed against a sealing disc with proximal and distal strut assemblies, after the introducer has been removed.
