The Langley diagnostic catheter has two polyisoprene balloons fixed in tandem on one 2-channel shaft, each connected to a 1500mm color-coded pressure line. Each line is Ch6 and fitted with a 3-way tap to enable rapid inflation and deflation.
A moveable silicone flange ensures the catheter will not ingress further into the bowel once placed by the practitioner. The Langley catheter is single-use and non-sterile.
