Use of the ArgoCap™

The ArgoCap™ is an endoscopic cap for the precise ablation of superficial lesions during APC treatment* in the gastrointestinal tract. It can be used wherever argon plasma coagulation is used, for example for the treatment of:

  • Barrett's esophagus
  • Ectopic gastric mucosa
  • GAVE syndrome
  • Angiodysplasia
  • Radiation proctitis

The ArgoCap™

The ArgoCap™ enables secure guidance and firm fixation of the APC probe during argon plasma coagulation. The defined position of the APC probe inside the cap allows homogeneous and focused treatment.

In this way, tissue adhesion and possible tissue adhesion of the APC probe can be avoided even during gastrointestinal peristalsis.

The special cap design angles the probe, which improves endoscopic handling and increases accessibility to the target tissue.

As the probe is guided along the outside of the endoscope shaft, the working channel remains free, e.g. for the simultaneous use of an additional instrument.

One packaging unit contains three caps.
