The description details a standard ultrasound system that measures bladder volume based on signal intensity and echo detection. There is no mention of AI/ML algorithms for image processing, pattern recognition, or predictive analysis. The performance studies focus on standard device testing and substantial equivalence to a predicate device, not on the performance of any AI/ML component.
No.
The device is intended to provide diagnostic information about urine dynamics and volume, not to provide therapy or treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "intended to provide the diagnostic information of the visualized urine dynamics acquired from the volume of the urinary bladder."
No
The device description explicitly states it consists of a "main body and an ultrasonic probe" and describes the physical components and their interaction with the body to acquire ultrasound data. It also mentions electrical safety and biocompatibility testing, which are relevant to hardware components.
Based on the provided information, the Lilium α-200E is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Lilium α-200E's Function: The Lilium α-200E uses ultrasound to non-invasively measure the volume of urine within the bladder. It does not analyze a sample of urine taken from the body.
- Intended Use: The intended use is to provide diagnostic information about visualized urine dynamics and bladder volume, which is a physical measurement, not an analysis of a biological sample.
- Device Description: The description clearly states it measures urine volume non-invasively using ultrasound applied to the outside of the abdomen.
Therefore, the Lilium α-200E falls under the category of a medical device that uses imaging (ultrasound) for diagnostic purposes, but it is not an In Vitro Diagnostic device.

Device Description
Lilium α-200E is a portable, battery powered, software controlled ultrasound system used to acquire and display real time A-mode images of the bladder. The Lilium device consists of a main body and an ultrasonic probe. Lilium device is used to measure urine volume inside the bladder non-invasively. In addition, it provides urine volume in the bladder at regular intervals and graphically displays the gradual increase of urine collection. It alerts when a set volume is attained. The device retains history. This information aids healthcare professionals, patients, and caregivers in providing proper continence care for those with urination difficulties. The device has wireless capabilities.
The Lilium device measures urine volume by means of a probe that has four ultrasound sensors aligned vertically. The sensor aligned side is applied to outside the abdomen wall so the probe can emit ultrasound (Mode A) toward the bladder and receive the echoed signals. The device the signal intensity to measure the height and depth of the bladder. These measurements determine the size of the bladder and quantify the filling of the bladder (urine volume is displayed on the screen. The system also includes indicator lights to indicate for urine volume and for correct positioning of the device.
The operating principle of the device is as follows:
An ultrasonic probe in which ultrasound transducers are arranged is placed on the abdominal surface, above the pubic bone, along the extending direction of the urinary bladder. When the ultrasound is transmitted from the probe, transducers put on the base part of the bladder detect echoes or ultrasonic reflections first when the urine begins to accumulate. As the bladder volume increases, transducers on the upper bladder detect echoes.

There was no human clinical testing required to support the medical device as the indications for use is equivalent to the predicate device. These types of devices, including the predicate devices, have been on the market for many years with proven safety and efficacy for the device. The non-clinical testing detailed in this submission supports the substantial equivalence of the device.
11. Statement of Substantial Equivalence
By definition, a device is substantially equivalent to a predicate device when the device has the same intended use and the same technological characteristics as the previously cleared predicate device. Or the device has the same intended use and different technological characteristics that can be demonstrated that the device is substantially equivalent to the predicate device, and that the new device does not raise additional questions regarding its safety and effectiveness as compared to the predicate device(s).
The Lilium α-200E, as designed and manufactured, is determined to be substantially equivalent to the referenced predicate device.
