Abstract
A gastroplasty method involves a staple line that terminates prior to reaching the gastroesophageal junction such that the bypassed portion of the stomach does not require resection. Additionally, bougies are taught that assist a physician in following the improved staple line of the present invention.
Claims20
A bougie for use in performing a gastroplasty, the bougie comprising:
- an elongate body having a segment configured to enter a stomach of a patient,
- the segment of the elongate body being shaped to follow a lesser curve of the stomach;
- an extension member having a distal end connected to the segment of the elongate body, the extension member being movable between:
- a retracted position in which the extension member lies along a portion of the segment of the elongate body, and
- an extended position in which the extension member extends at an angle away from the portion of the segment of the elongate body for positioning the extension member away from a gastroesophageal junction of the stomach;
- and
- a ring being positioned to surround the elongate body and configured to slide along the extension member to bias the extension member in at least one of:
- the extended position when the ring is placed nearby the distal end of the extension member, and
- in the retracted position when the ring is placed nearby a proximal end of the extension member.

A method for performing a gastroplasty using a bougie, the method comprising:
- inserting a segment of the bougie into a stomach of a patient, the bougie comprising an extension member which is in alignment with the segment of the bougie when in a retracted position during insertion;
- sliding a ring in a distal direction along the extension member to bias the extension member from the retracted position to an extended position at an angle away from the segment to establish a junction line along which opposed walls of the stomach are joinable;
- and
- joining the opposed walls of the stomach along the junction line and away from the gastroesophageal junction of the stomach.

A method for performing a gastroplasty using a bougie, the method comprising:
- inserting a segment of the bougie into a stomach of a patient, the bougie comprising an extension member which is in alignment with the segment of the bougie when in a retracted position during insertion;
- establishing a junction line along which opposed walls of the stomach are joinable by moving the extension member of the bougie in an extended position within the stomach wherein the extension member extends at an angle away from the segment to define the junction line;
- joining the opposed walls of the stomach along the junction line and away from the gastroesophageal junction of the stomach;
- and
- sliding a ring in a proximal direction along the extension member to bias the extension member from the extended position to the retracted position pursuant to the joining of the opposed stomach walls along the junction line.
