|Condition or disease||Intervention/treatment||Phase|
|Barrett Esophagus||Other: Survey Administration Device: Tethered Capsule Endoscope||Not Applicable|
I. Evaluate image quality and usability of the tethered capsule endoscope after repeated clinical use and reprocessing.
II. Evaluate safety issues associated with the use of the device for this subject population - was there any noticeable difference from prior study of subjects at high risk of Barrett's esophagus using the same device, but without reprocessing.
I. Study other specified device characteristics or device application considerations.
II. Obtain preliminary data for use in designing a subsequent pivotal study of the device.
Patients swallow the tethered capsule endoscope (TCE) and undergo endoscopic examination while they are seated on a standard endoscopy gurney. Patients undergo standard of care EGD on the same day.

Experimental: Screening (TCE)
Patients swallow the TCE and undergo endoscopic examination while they are seated on a standard endoscopy gurney. Patients undergo standard of care EGD on the same day.
Other: Survey Administration
Device: Tethered Capsule Endoscope
Other Name: TCE
- Consistent image quality [ Time Frame: At the conclusion of TCE exam (day 1) ]Consistent image quality defined as no significant degradation of lateral spatial resolution [line pairs per mm] and axial depth of focus [mm], maximum field of view [degrees cone angle], and color fidelity [qualitatively matches color chart] when measured after use in the clinic using color and resolution test targets and a test chamber to measure field of view. The standard care EGD will be digitally recorded to allow for review and comparison to the TCE procedure by a blinded, expert endoscopist.
- Consistent usability defined as no significant change to the tolerance rating given by the patient by survey, and ease of use by the physician by survey, and time for completing the examination [ Time Frame: At the conclusion of TCE exam (day 1) ]
- Incidence of adverse events associated with TCE use [ Time Frame: Up to 1 year ]
