Classification: CPC A | IPC A

Claim 15:
16. An apparatus comprising:
(a) a series of beads configured to be interconnected to form a loop around an anatomical structure in a patient, wherein the loop is configured to transition between a contracted configuration and an expanded configuration, wherein the loop in the contracted configuration is configured to prevent fluid flow through the anatomical structure, wherein the loop in the expanded configuration is configured to permit fluid flow through the anatomical structure;
(b) a magnet disposed within each bead in the series of beads and configured to generate a magnetic field to magnetically bias the loop toward the contracted configuration; and
(c) a secondary element disposed within each of the beads and configured to increase the magnetic field of the magnet, wherein the secondary element is configured to cause the magnetic field to have focus extending high magnetic flux in combination with increased areas of repressed magnetic field strength.
