摘要：
Devices and methods are provided for accessing a bodily opening that, among other things, are safe, reliable and repeatable. One embodiment of a device for anchoring to tissue includes an elongated tube and a magnet. The elongated tube has a proximal end opposite a distal end, and defines a central axis. The magnet is attached to the distal end of the elongated tube and has a magnetic field attractive to the magnetic material in the tissue. The magnet has an annular shape defining an aperture through which the elongated tube extends.
