Indications For Use:
-
- Urinary Incontinence : Stress, Urge and Mixed Incontinence
-
- Neuromuscular Reeducation
The Pathway STM-10 is used to stimulate the pelvic floor muscles for the treatment of incontinence. The Pathway Vaginal or Anal EMG/Stim perineometer sensor is connected to the Pathway STM-10 device to provide stimulation to the patient. This assists the patient with muscle contractions.
The Pathway STM-10 uses Pathway EMG/Stim Perineometer Sensors which are single-user sensors. The patient inserts the sensor into the vagina or rectum and uses the Pathway STM-10 to electrically stimulate the pelvic floor muscles to assist the contraction. The aim is to improve the strength and control of the pelvic floor muscles.
The provided text describes a 510(k) summary for the Pathway STM-10 Pelvic Floor Stimulator. This type of submission is for demonstrating substantial equivalence to a predicate device, not for proving the safety and effectiveness of a novel device through extensive clinical trials with acceptance criteria.
Therefore, many of the requested categories (e.g., sample size for test set, number of experts for ground truth, adjudication method, MRMC study, sample size for training set, ground truth for training set) are not applicable (N/A) in this context as they pertain to clinical or algorithm-specific performance studies that were not part of this 510(k) submission.
Here's the information that can be extracted from the provided document:
1. A table of acceptance criteria and the reported device performance
The document does not explicitly define "acceptance criteria" in the way it would for a clinical trial (e.g., a specific sensitivity or specificity target). Instead, the "acceptance" for this 510(k) summary is demonstrating substantial equivalence to a predicate device (Pathway CTS 2000). The "device performance" is reported through a comparison of technical characteristics and bench test results.

§ 876.5320 Nonimplanted electrical continence device.
(a)
Identification. A nonimplanted electrical continence device is a device that consists of a pair of electrodes on a plug or a pessary that are connected by an electrical cable to a battery-powered pulse source. The plug or pessary is inserted into the rectum or into the vagina and used to stimulate the muscles of the pelvic floor to maintain urinary or fecal continence. When necessary, the plug or pessary may be removed by the user. This device excludes an AC-powered nonimplanted electrical continence device and the powered vaginal muscle stimulator for therapeutic use (§ 884.5940).(b)
Classification. Class II (performance standards).
