Contemporary research has confirmed that the upper esophageal sphincter is not round. Conventional devices address less than half of the mean cross section of the UES1,2.
Infinity® Esophageal Dilation System is designed for the treatment of swallowing impairment caused by upper esophageal sphincter dysfunction. Simple transnasal system with unrivaled size range.
Infinity® is contoured to the specific physiology of the upper esophageal sphincter, providing nearly double the lateral inflation dimension of conventional devices.
Available exclusively from Bryan Medical.
Catheter length is 110 cm
