iStim PR-13 Anal Probe Instruction Manual

Model: PR-13 | Brand: iSTIM

1. Introduction and Product Overview

The iStim PR-13 Anal Probe is a premium, cylindrical, and slimline device designed for comfortable insertion and effective electrical muscle stimulation. It features a sliding end-stop, allowing users to adjust the depth of insertion for targeting the anal sphincter or deeper pelvic floor muscles. This probe is intended for use with an Incontinence EMS unit to assist in the relief of incontinence and to train sphincter muscles, enhancing resistance to fatigue and reducing involuntary bladder contractions.

The probe facilitates Kegel exercises, which are simple clench-and-release movements that strengthen the muscles supporting the uterus, bladder, and bowel. These exercises are beneficial for individuals experiencing urine leakage or bowel control issues. When connected to an Incontinence EMS stimulator, the iStim PR-13 probe enables automated Kegel exercises.

It addresses both stress incontinence, characterized by leakage during activities like sneezing or coughing, and urge incontinence, involving unexpected leakage due to an overactive bladder. The iStim PR-13 probe is a device designed to help reduce these common types of incontinence.
