Anorectal Manometric Catheters

Unique Configurations

5 Lumen ARM34
This new M3 5 lumen catheter utilizes the same extrusion used in the 9 lumen M3. The significant difference is that there are four recording sites. This catheter is designed to be used with a recording system having four pressure recording channels. Internal and external anal sphincter pressures are measured by a station pull through technique. A rectal distending balloon is attached to the distal end of the catheter. Internal anal sphincter relaxation can be measured with any of the recording sites during balloon distention.

9 Lumen ARM38
A more technically advanced catheter is constructed from the M3 single extrusion catheter material. This catheter has eight recording sites plus a large central lumen for inflation of the rectal distending balloon. With the eight recording sites spaced at 0.5 cm intervals, the internal and external anal sphincter pressures can be measured concurrently with the assembly stationed within the sphincteric high pressure zone. This unique design permits accurate, simultaneous assessment of internal sphincter relaxation and external sphincter augmentation during balloon distention of the rectum. The rectal distending balloon can be inflated with volumes of air up to 150 milliliters. These catheters are reusable and may be gas sterilized.
