Abstract:
1. A method for treating a body lumen of a patient, the method comprising: placing at least two magnetic or magnetable devices within a wall of the body lumen at a preselected location, wherein the magnetic or magnetizable devices are attracted to one another and wherein movement of the magnetic devices due to their attraction at least partially constricts the lumen; positioning a magnetizing device at a location near the implanted at least two devices; magnetizing the at least one of the at least two devices with the magnetizing device; positioning a pressure sensing device in the body lumen at a pressure sensing location near the implanted at least two magnetic or magnetizable devices; sensing a pressure within the body lumen at the pressure sensing location; and adjusting the magnetic power of at least one of the two magnetic or magnetizable devices based on the sensed pressure.
