Catheter structure and method for locating tissue in a body organ and simultaneously delivering therapy and evaluating the therapy delivered

摘要

A catheter structure is provided for use with an electroviscerogram (EVG) system. The catheter structure includes an elongated tube structure having distal and proximal ends. Three electrodes are associated with distal end of the tube structure and are constructed and arranged obtain signals relating to myoelectrical activity internally of an intra-abdominal organ to thereby locate targeted tissue that includes main pathways of electrical generation in the organ. Therapy delivery structure, associated with the distal end of the tube structure and separate from the electrodes, is constructed and arranged to provide therapy at the targeted tissue simultaneously as the electrodes obtain the signals at the targeted tissue so that effectiveness of the therapy can be monitored.

1. An electroviscerogram (EVG) system with a catheter structure for use with an, the catheter structure comprising:
an elongated tube structure having distal and proximal ends, three electrodes, associated with distal end of the tube structure, constructed and arranged obtain electrical signals relating to myoelectrical activity internally of an intra-abdominal organ to thereby locate targeted tissue that includes main pathways of electrical generation in the organ, and therapy delivery structure, associated with the distal end of the tube structure and separate from, different from, and not connected with the three electrodes, the therapy delivery structure being constructed and arranged to provide therapy to effect a normal physiological function of at the targeted tissue simultaneously as the three electrodes obtain the electrical signals at the targeted tissue the EVG system being constructed and arranged to monitor effectiveness of the therapy at the targeted tissue by simultaneously monitoring changes in the electrical signals at the targeted tissue obtained by the three electrodes due to the therapy delivery structure effecting the normal physiological function of the targeted tissue.
