Clinical Pilot Study of the Percutaneous Ultrasound Jejunostomy Procedure
A Single Center, Pilot Study to Evaluate the Feasibility of the Percutaneous Ultrasound Jejunostomy (PUJ)
The purpose of this study is to evaluate the feasibility and performance of the Percutaneous Ultrasound Jejunostomy (PUJ) procedure that utilizes a novel device (PUMA-J System) in conjunction with widely available ultrasound technology and endoscopic guidance.
The procedure will be performed in up to 10 eligible subjects. Patients will be followed for 2 days following performance of PUJ to assess for potential complications.

Detailed Description
Jejunostomy tubes (J-tubes) provide a path for nutrition delivery directly into the small intestinal lumen, bypassing the mouth, esophagus, and stomach for patients who have difficulty with proximal gut feeding. Many medical conditions may require J-tubes, including cancers, gastroparesis, and patients with high risk of aspiration.
A recent innovation by CoapTech addresses technical and procedural limitations of current jejunostomy tube placement methods by leveraging ultrasound for visualization and magnets for control of the jejunal loop. The Percutaneous Ultrasound Magnet Aligned (PUMA) System enables clinicians to affix jejunal loops superficially via magnetic coaptation and visualize the planned stomal tract using ultrasound. The purpose of this pilot clinical study is to test the feasibility of the PUMA-Jejunostomy (PUMA-J) System in adults requiring a jejunostomy tube.
This is a single-center, non-randomized, non-blinded feasibility study to evaluate the performance and safety of the PUJ procedure that utilizes a novel device (PUMA-J System).

Exclusion Criteria:
- Temperature ≥ 38 C
- Systolic BP < 90 or > 180 mmHg
- Heart Rate < 50 or > 120
- Presence of a contraindication to being in proximity to a magnet (e.g. pacemaker)

- Other standard general contraindications to endoscopy
- Pacemakers or other electronically active implantable devices
- Small bowel fistula
- Any other medical condition(s) that may put the patient at risk or influence study results in the investigator's opinion, or that the investigator deems unsuitable for the study.
