A magnetic targeting system suitable for facilitating navigation to a target area located in vivo, said system comprising: a biocompatible device and a plurality of anchoring members having a proximal end and a distal end, said distal end constructed and arranged to secure to a target area located in vivo, wherein said proximal end is constructed and arranged to receive a magnetic material; a magnetic material configured to be received into said proximal end, a hollow extender (12a, 12b, 12c) coupled to each said anchoring member, each extender (12a, 12b, 12c) having an open top and at least a first said extender having a longitudinally extending slot characterized in that: the targeting system further comprises a targeting member having a first end and a second end, and at least said first end includes a steering material influenced by a magnetic field, a tether means attached to said second end of the targeting member and to the biocompatible device; the magnetic material is effective for attracting or repelling said steering material in vivo such that, when said magnetic material is received in said proximal end of said anchoring member the magnetically influenced proximal end of said anchoring member interacts with said first end of said targeting member such that said connected biocompatible device is positionable relative to said target area; and the targeting member and the extenders (12a, 12b, 12c) are so sized that the targeting member can pass into the hollow extender (12a,12b, 12c) through said open top and, for at least said first extender, the targeting member can pass out of the extender through said longitudinal extending slot. a biocompatible device and a plurality of anchoring members having a proximal end and a distal end, said distal end constructed and arranged to secure to a target area located in vivo, wherein said proximal end is constructed and arranged to receive a magnetic material; a magnetic material configured to be received into said proximal end, a hollow extender (12a, 12b, 12c) coupled to each said anchoring member, each extender (12a, 12b, 12c) having an open top and at least a first said extender having a longitudinally extending slot characterized in that: the targeting system further comprises a targeting member having a first end and a second end, and at least said first end includes a steering material influenced by a magnetic field, a tether means attached to said second end of the targeting member and to the biocompatible device; the magnetic material is effective for attracting or repelling said steering material in vivo such that, when said magnetic material is received in said proximal end of said anchoring member the magnetically influenced proximal end of said anchoring member interacts with said first end of said targeting member such that said connected biocompatible device is positionable relative to said target area; and the targeting member and the extenders (12a, 12b, 12c) are so sized that the targeting member can pass into the hollow extender (12a,12b, 12c) through said open top and, for at least said first extender, the targeting member can pass out of the extender through said longitudinal extending slot. the targeting system further comprises a targeting member having a first end and a second end, and at least said first end includes a steering material influenced by a magnetic field, a tether means attached to said second end of the targeting member and to the biocompatible device; the magnetic material is effective for attracting or repelling said steering material in vivo such that, when said magnetic material is received in said proximal end of said anchoring member the magnetically influenced proximal end of said anchoring member interacts with said first end of said targeting member such that said connected biocompatible device is positionable relative to said target area; and the targeting member and the extenders (12a, 12b, 12c) are so sized that the targeting member can pass into the hollow extender (12a,12b, 12c) through said open top and, for at least said first extender, the targeting member can pass out of the extender through said longitudinal extending slot.
