G-tube placement is one of the most commonly performed endoscopic procedures in the United States, with an estimated 100,000 to 125,000 procedures performed annually. Given the aging population both in the United States and Asia – as well as the growing prevalence of chronic diseases worldwide – the number of G-tube insertions is expected to continue to rise.

Feeding tube placement using PUMA-G technology is remarkably simple, streamlining the process and allowing non-surgical medical providers to perform this procedure at a patient’s bedside. Unlike PEG which requires reuse of expensive endoscopes, PUMA-G’s single-use technology means no cleaning is required and no expensive equipment is needed.

Three Simple Steps 

G-tube placement using the PUMA-G system involves three steps:

  1. Achieve coaptation - Following orogastric placement of the balloon catheter, bring the external magnet into the field to achieve coaptation. Introduce fluid into the balloon catheter to enable ultrasound visualization.  
  2. Identify a safe gastrostomy tract - Using standard ultrasound techniques, find a safe gastrostomy tract, avoiding organs and vasculature. With the external magnet, make minor placement adjustments as needed. Target balloon with needle under ultrasound guidance. 
  3. Use the standard PUSH technique - Once the needle is placed, insert the guidewire and retract the balloon/guidewire pairing in tandem out through the mouth. Place the gastrostomy tube over the guidewire using standard PUSH (Sacks-Vine) technique. Dilate and secure gastrostomy tube.

PUMA-G technology is expected to undergo FDA review in June 2018 and to be available on the market in Fall 2018.
