Abstract
Systems and methods for accessing, stabilizing and sealing a device attached to a tissue surface comprising a tissue attaching device having an outer base ring defining an opening therethrough and a distally projecting tissue attachment element. The systems variously utilize annular sealing flanges distally attached to the outer base ring outside or inside the tissue attachment element to create a fluid tight seal. The systems variously utilize coils with regions of differing pitch to create sealing tissue pressure. Methods for installing an apical attaching device with a transapical port into a patient, comprising assessing the patient's viability for installation of the apical attaching device by determining an Index of Tissue Elasticity (ITE).
