Regulatory Classification
Identification
A urodynamics measurement system is a device used to measure volume and pressure in the urinary bladder when it is filled through a catheter with carbon dioxide or water. The device controls the supply of carbon dioxide or water and may also record the electrical activity of the muscles associated with urination. The device system may include transducers, electronic signal conditioning and display equipment, a catheter withdrawal device to enable a urethral pressure profile to be obtained, and special catheters for urethral profilometry and electrodes for electromyography. This generic type of device includes the cystometric gas (carbon dioxide) device, the cystometric hydrualic device, and the electrical recording cystometer, but excludes any device that uses air to fill the bladder.
Special Controls
*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 876.9.

Dear Suranjan Roychowdhury:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

## 4. Device Description
The subject device is a modified Glean Urodynamics System. The specific modification to the subject device consists of adding an Abdominal Sensor component (GUS-1000-A) to the system. The Abdominal Sensor
{5}
K253537
Page 2 of 5
measures abdominal pressure and enables detrusor pressure to be calculated using the Glean Urodynamics System (GUS) to conduct multi-channel urodynamics studies. Addition of the Abdominal Sensor component enables the subject device to perform multi-channel urodynamics studies. The modified Glean Urodynamics System (GUS) is a multi-channel urodynamic system indicated for standard Urodynamic tests such as Uroflow (UF), Cystometrogram (CMG), Urethral Pressure Profile (UPP), and Micturition Studies (MS).
The Glean Urodynamics System obtained market clearance through the original 510(k) Premarket Notification K243052. No changes were made to the intended use, indications for use, or technological characteristics of the predicate device's three physical components, the Bladder Sensor, Insertion Tool, and Uroflowmeter. The Glean Mobile App (Clinician) and Glean Web App software were modified to include use with the Abdominal Sensor. The Glean Mobile App (Patient) was not modified.
The multi-channel GUS consists of four physical component elements: Bladder Sensor, Abdominal Sensor, Insertion Tool, and Uroflowmeter, as well as three software applications: Glean Mobile App (Clinician), Glean Mobile App (Patient), and Glean Web App. The patient may use the Glean Mobile App as a digital voiding diary, logging fluid input, leakage, urgency, and other urological symptoms. The clinician may use the Glean Mobile App to prepare the Sensor for insertion, log symptoms, and download data. The Glean Web App may be used by clinicians to view and analyze data.
The Bladder Sensor is inserted through the urethra into the bladder using the Insertion Tool. Once inserted, the Sensor has a Removal String that hangs out of the urethra to enable removal of the Sensor. The Sensor may stay in the bladder for the entire duration of monitoring while collecting data. The Sensor stores data that may be wirelessly transmitted to the Glean Mobile App (Clinician) once it is removed from the body.
The Abdominal Sensor is manually inserted into the anorectal canal. Once inserted, the Abdominal Sensor has a removal string that extends from the anus to enable removal of the Sensor. The Sensor may stay in the rectum for the entire duration of monitoring while collecting data. The Sensor stores data that may be wirelessly transmitted to the Glean Mobile App used by the clinician once it is removed from the body.
The Uroflowmeter is used to measure voided volume and flow. The Glean Mobile App (Clinician) wirelessly receives data from the Uroflowmeter after the patient has completed a voiding cycle.
## 5. Indications For Use
