Abstract
Abstract Method and apparatus for controlling the output of a cardiomyostimulator comprising a magnet of sufficient intensity to interrupt an output signal of a cardiomyostimulator when placed externally over the abdomen of a patient in whom a cardiomyostimulator has been implanted in close proximity to the cardiomyostimulator, and a belt member for removably securing the magnet over the patient's abdomen.

Claims Analysis
Total Claims: 35
Claim 1
Independent Claim
249 words
A method for use with the cardiomyoplasty surgical procedure to permit patient control of the simulation and conditioning of a translocated muscle flap outside of the confines of a health care facility comprising: a) performing the cardiomyoplasty surgical procedure on a patient; b) implanting a cardiomyostimulator in the abdomen of said patient as part of said cardiomyoplasty surgical procedure, wherein said cardiomyostimulator provides a continuous output signal of patterned episodes of pulsed stimuli and wherein said cardiomyostimulator includes a means for interrupting said output signal in the presence of a magnetic field; c) stimulating said muscle flap with said output signal; d) interrupting, by said patient as said patient desires or requires, said stimulation of said muscle flap by interrupting said output signal by associating a magnet over the external surface of said abdomen with a means for removably securing said magnet over said external surface of said abdomen in close proximity to said cardiomyostimulator, said magnet having a field strength of sufficient intensity to interrupt said output signal generated by said cardiomyostimulator so long as said magnet is maintained in close proximity to said cardiomyostimulator; e) resuming, by said patient as said patient desires or requires, said stimulation of said muscle flap by resuming said output signal by disassociating said magnet from said surface of said abdomen and said close proximity to said cardiomyostimulator and; f) controlling said stimulation and conditioning of said muscle flap by said patient by repeating steps (d)-(e) as said patient requires or desires.
