GI Organ Tracking Via Balloon Applicators
Esophageal Cancer, Kidney Cancer, Larynx Cancer
About this trial
This is an interventional device feasibility trial for Esophageal Cancer focused on measuring Gastric balloon
Eligibility Criteria
Inclusion Criteria:
- Scheduled to receive intra-thoracic or abdominal radiation therapy. It is not required that the stomach be in the radiation field.
- At least 18 years of age.
- ECOG performance status ≤ 1
- Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).
Exclusion Criteria:
- Prior trauma or surgical intervention that would alter the anatomy of the upper airs (nasogastric route), esophagus or stomach.
- Previous complete or partial surgical resection of the esophagus, stomach, or duodenum.
- Presence of implantable devices (e.g., automatic internal cardiac defibrillator, cardiac or gastric pacemaker).

Arms of the Study
Arm 1
Experimental
Occlusion balloon catheter
-Each participant will have an embolectomy balloon that is FDA approved for peripheral and neurovasculature temporary occlusion placed by nose or mouth. Anatomical position of balloon will be verified by on-board MR or CT imaging in to assess feasibility of using a duodenal balloon in this population. Participants who are imaged on the MR treatment machine will also be imaged with 4 or 8 frame per second sagittal imaging to assess real-time stomach and balloon respiratory motion. Participants imaged on CT based imaging (i.e. Ethos/Halcyon ring gantry system) will have CBCTs acquired at timed intervals (approximately 5-10 minutes between scans). After imaging, the balloon will be deflated and removed at that time.
