Abstract
Devices and related methods to engage tissue layers to access the space between the layers are provided. The access devices include engagement arms that can be deployed and retracted to easily engage the top tissue layer and allow it to be separated from the underlying layer. The engagement arms are coupled to an actuation rod that is in turn coupled to a switch or lever that allows a user to control the actuation from outside the patient. The engagement arms and coupling to the actuation rod are unique and compact to ensure the entire mechanism fits in a small diameter shaft.
