Abstract
Disclosed are various embodiments for improved surgical devices and methods of using the same in connection with bariatric and gastroesophageal surgery. The present disclosure includes a lighted bougie device that can include an elongate member and a light source. The light source can be configured to emit near infrared light. The light source can also be positioned about the bougie such that light emitted from the light source illuminates along a portion of the bougie.
Claims27
A lighted device for use in a surgical procedure, the lighted device comprising:
- an elongated member having a distal end for inserting into an operative field of a patient and having a proximal end;
- a handle coupled to the proximal end of the elongated member;
- and
- a plurality of light sources disposed along the elongated member and configured to emit light in a first wavelength range and a second wavelength range different from the first wavelength range,
- wherein:
- a first light source closest to the distal end of the elongated member among the plurality of light sources is disposed at a first location of the elongated member,
- a second light source closest to the proximal end of the elongated member among the plurality of light sources is disposed at a second location of the elongated member,
- a length of the elongated member between the first location and the second location is at least 50% of a length of the operative field of the patient, and
- light sources in at least a subset of the plurality of light sources are spaced apart along a length direction of the elongated member at a predetermined interval of between 0.5 cm and 5 cm, thereby allowing use of the elongated member and the light sources as a ruler for one or more intraoperative measurements.

A lighted device for use in a surgical procedure, the lighted device comprising:
- an elongated member having a distal end for inserting into an operative field of a patient and having a proximal end;
- a handle coupled to the proximal end of the elongated member;
- and
- a plurality of light sources disposed along the elongated member and configured to emit light in a first wavelength range and a second wavelength range different from the first wavelength range,
- wherein the plurality of light sources comprises at least 8 individual light sources that are spaced apart along a length direction of the elongated member at a predetermined interval of between 0.5 cm and 5 cm, thereby allowing use of the elongated member and the light sources as a ruler for one or more intraoperative measurements.

A lighted device for use in a surgical procedure, the lighted device comprising:
- an elongated member having a distal end for inserting at least a first portion of the elongated member of the lighted device into an operative field of a patient and having a proximal end;
- a handle coupled to the proximal end of the elongated member;
- and
- a plurality of light sources disposed at the first portion of the elongated member and configured to emit light in a first wavelength range that is able to transmit through one or more first tissues of the patient but unable to transmit through one or more second tissues of the patient and a second wavelength range that is able to transmit through both the one or more first tissues and the one or more second tissues of the patient,
- wherein:
- a length of the first portion of the elongated member is at least 50% of a length of the operative field of the patient;
- the plurality of light sources comprises at least 8 individual light sources to emit light in a range of about 700 nm to about 1300 nm;
- adjacent light sources in the at least 8 individual light sources are spaced apart along a length direction of the elongated member at a predetermined interval of between 0.5 cm and 5 cm to facilitate one or more intraoperative measurements.
