Embodiment Construction

[0105] First refer to Figures 1A-1F , showing devices, systems and methods for positioning a helical anchor within the location of the mitral valve of a patient's heart. In this series of figures, the system is delivered from the apex of the left ventricle. However, it should be appreciated that the system may be used by implanting directly into the open heart from the atrium, ventricle, or aorta, or the implant may be delivered from a catheter into the left atrium or retrograde from the aortic valve into the left heart Do it indoors. Similarly, the system may be introduced into the atria through the open chest or percutaneously via the apex of the heart.

[0106] Figure 1A An introducer 2 is shown inserted into the apex 6 of the left ventricle 10 of the patient's heart 14 through a small thoracotomy, sternotomy, or from below the diaphragm through an epigastric incision. A particularly advantageous approach is to make a small incision in the patient's chest adjacent to ...

Abstract

Various systems, devices and methods associated with the placement of a dock or anchor (72) for a prosthetic mitral valve (120). The anchor (72) may take the form of a helical anchor having multiple coils (104, 108) and / or a stent-like structure. Various methods include different levels of minimal invasive procedures for delivering the prosthetic valve anchor (72) and prosthetic valve (120), as well as tissue anchors for plication or other purposes to the mitral valve position in the heart (14).
