Figure 1. Retentia Clip. Key technical information.
The Retentia Clip has some interesting and nice features:
a) it is rotatable,
b) it can be deployed with scope in retroflexed position,
c) it can open and close repeatedly. I opened and closed one 30 times,
d) its catheter has a 2.5 mm outer diameter, allowing for simultaneous suction of air and liquids through the working channel.
These are very convenient features, as they allows the endoscopist to be 100% sure of the desired placement location (vessel, base of polyp, wound closure, etc). Additionally, this clip is quite big, with arm extending up of 16 mm. This allows for grasping more tissue or tackling larger defects. Lastly, the clip’s stem is short (6 mm, yellow arrow), making it ideal for small lumens, such as esophagus or small bowel.
Disclaimer: I have no conflict of interest (COI). No commercial interest.
Tools don't save patients—skilled hands do.
The Retentia clip offers 16mm arms and 360-degree rotation, but these features are useless without the clinical judgment to deploy them correctly. Knowing how to utilize a rotatable, reopenable clip allows for 100% certainty before you deploy.
