Electromagnetic bougienage method
First Claim
1. A method for lengthening atretic segments of a patient by electromagnetic bougienage to facilitate subsequent primary anastomosis without tension, said method comprising the following steps:
- a. inserting a first magnetic bougie into a first atretic segment so that the leading end of the first magnetic bougie is positioned at the closed end of the first segment;
b. inserting a second magnetic bougie into a second atretic segment so that the leading end of the second magnetic bougie is positioned at the closed end of the second segment;
c. intermittently electromagnetically energizing the first and second magnetic bougies to urge the two bougies towards each other, said intermittent energizing taking place over a total time period exceeding at least two days; and
d. after the intermittently magnetized bougies have sufficiently lengthened the atretic segments to permit primary anastomosis without tension, withdrawing the magnetic bougies from the segments.

Abstract
A method for lengthening atretic segments of a patient by electromagnetic bougienage to facilitate subsequent primary anastomosis without tension. In the preferred method, two magnetic bougies are inserted into the atretic segments so that the magnetic bougies are positioned at the closed ends of the segments. An annular electromagnet is placed around the patient'"'"'s body and is cycled on and off to urge the magnetic bougies towards each other over a period of time in order to lengthen the atretic segments. The magnetic bougies are then withdrawn after which primary anastomosis is accomplished.

16. A method for lengthening atretic esophageal segments of a patient by electromagnetic bougienage to facilitate subsequent primary anastomosis without tension, said method comprising the following steps:
-
a. inserting a suction tube having a first magnetic bougie at its leading end through the patient'"'"'s mouth and into the upper esophageal pouch so that the rounded leading end of the first bougie is positioned at the closed end of the first atretic segment; b. applying intermittent sump suction to the suction tube to pump fluids out of the upper pouch; c. affixing a hollow open-ended cable sheath to a previously implanted gastrostomy tube and pushing a semi-flexible retrieval cable having a second magnetic bougie at its leading end through the sheath, through the patient'"'"'s abdominal wall, and through the wall of the lower esophageal pouch so that the rounded leading end of the second bougie is positioned at the closed end of the second atretic segment; d. positioning an annular electromagnet around the patient'"'"'s body so that the two magnetic bougies are positioned substantially along the axis of the core of the electromagnet and on opposite sides of and approximately equidistant from the plane of the core of the electromagnet; e. intermittently energizing the electromagnet to urge the first and second bougies towards each other, said intermittent energizing step taking place over a total time period exceeding at least two days; and f. after the intermittently magnetized bougies have sufficiently lengthened the atretic segments to permit primary anastomosis without tension, withdrawing the magnetic bougies from the segments.

17. A method for lengthening an atretic segment of a patient by electromagnetic bougienage to facilitate subsequent primary anastomosis without tension, said method comprising the following steps:
-
a. inserting a magnetic bougie into an atretic segment so that the leading end of the magnetic bougie is positioned at the closed end of the segment; b. intermittently electromagnetically energizing the magnetic bougie to urge the bougie in the direction of the closed end of the segment, said intermittent energizing taking place over a total time period exceeding at least two days; and c. after the intermittently magnetized bougie has sufficiently lengthened the atretic segment to permit primary anastomosis without tension, withdrawing the magnetic bougie from the segment.
