Calibrating apparatus and method of using same for gastric banding surgery
First Claim
1. A method for performing a gastric banding operation on the stomach of a human body comprising the steps ofinserting into the opening of the stomach of a human body a calibrating apparatus comprising a single-lumen tubing which has a first orifice at the proximal portion thereof and a second orifice at the distal tip thereof which is operatively coupled to an elongated thin-walled sensor having a circular cross-section and which defines a cavity within the interior thereof and wherein the thin-walled sensor is capable of having its cross-sectional diameter varied in response to a variable force being applied to the exterior of the sensor, a toroidal-shaped balloon operatively coupled to and surrounding the exterior of the single-lumen tubing at a preselected location near the distal tip and an elongated tubing which extends from a location exterior to the single-lumen tubing, through the interior of the single-lumen tubing, and into communication with the interior of the balloon and proceeding the calibrating apparatus into the interior of the stomach;
- inflating the balloon while the calibrating apparatus is within the stomach by passing a fluid under pressure through said elongated tubing to expand the balloon to a selected expanded dimension and retrograding the inflated balloon against the stomach opening;
constricting the stomach located immediately below the expanded balloon by applying a adjustable gastric band around the periphery of the stomach and urging the interior of the stomach into engagement with and around the exterior of the sensor;
tightening the adjustable band around the periphery of the stomach, which in turn applies pressure around the periphery of the exterior of the sensor, until a selected pressure is detected as being applied to the sensor and suturing the band to form a passageway between the inner walls of the stomach wherein the passageway has a diameter which is substantially equal to the cross-sectional diameter of the sensor at the applied pressure developed by the adjustable band to establish an upper cavity having a volume which is substantially equal to the selected expanded dimension of the balloon and a lower cavity which communiates with the first cavity through said passageway having said predetermined cross-sectional area;
suturing together the sidewalls of the stomach forming the upper and lower cavities enclosing the adjustable gastric band to defining an annular-shaped opening around the adjustable gastric band; and
withdrawing the fluid from the interior of the balloon, collapsing the same, and retrograding the calibrating apparatus through the opening of the first cavity and out of the human body.

Abstract
A calibrating apparatus adapted to be inserted into and proceeded within the stomach of human body which includes a single-lumen tubing terminating in a proximal portion and a distal tip each of which have an orifice and wherein the single-lumen tubing has a first opening extending therethrough which is located at a selected distance from the proximal portion and a second opening which extends therethrough and which is located a predetermined distance from the distal tip, an elongated, thin-walled sensor having a circular-cross section and a cavity within the interior thereof and which is operatively coupled in a sealing relationship to the distal tip wherein the thin-walled sensor is capable of having its cross-sectional diameter varied in response to a force applied to the exterior of the sensor to vary the pressure of a fluid within the cavity, a balloon surrounding the exterior of said single-lumen tubing at the preselected location which encloses the second opening and an elongated tubing member which extends through the single-lumen tubing, through the first opening and into communication with the second opening is shown. A method for performing a gastric banding operation on the stomach of a human being utilizing the calibrating apparatus is also shown.
