The summary does not mention AI, ML, or related concepts, and the device description focuses on hardware components and pressure sensing.
No.
The device is used for real-time verification of needle tip placement, which is a diagnostic or procedural guidance function, not a therapeutic intervention itself.
Yes
The device's intended use clearly states "real-time verification of needle tip placement in the lumbar epidural space," which indicates it provides information to diagnose or confirm a physiological state (proper needle placement).
No
The device description explicitly lists hardware components including a primary unit, pneumatic foot pedal control, AC power cord, and a single-use disposable kit with physical components like a pressure sensor, syringe, and tubing. This indicates it is a hardware device with potentially integrated software, not a software-only device.
Based on the provided information, the CompuFlo® Epidural Computer Controlled Anesthesia System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The CompuFlo® system's intended use is for the real-time verification of needle tip placement in the lumbar epidural space within the patient's body. It does not analyze bodily fluids or tissues.
- The device description focuses on mechanical and electronic components for pressure sensing and control during a procedure performed directly on the patient. It doesn't involve reagents, test strips, or other components typically associated with in vitro testing.
- The performance study evaluates the success of the epidural procedure itself, not the results of a diagnostic test on a specimen.
The CompuFlo® system is a medical device used in vivo (within the living body) to assist a healthcare provider during a medical procedure.

Intended Use / Indications for Use
The CompuFlo® Epidural Computer Controlled Anesthesia System is intended for use with an epidural needle for the real-time verification of needle tip placement in the lumbar epidural space in patients over age of 18 who are required to have epidural needle placement as part of a medically necessary, in-patient or out-patient procedure, as established by their Health Care Provider.
4
Once Health Care Provider verifies the epidural needle placement in the lumbar epidural space, CompuFlo® Epidural Computer Controlled Anesthesia System is disconnected and the HCP continues with the medical procedure.
Device Description
The device consists of: (1) the primary unit, (2) a pneumatic foot pedal control, (3) an AC power cord and (4) single-use disposable kit, which include an external in-line fluid pressure sensor, a 20 mL plastic syringe, plastic tubing and an ID Adapter. Operation of the device is allowed when powered by the AC mains or by the internal battery source. The epidural needle and solution is not supplied in the disposable Kit.
Technological Characteristics
The CompuFlo® Epidural Computer Controlled Anesthesia System includes an injectionmolded plastic housing that contains the motor-driven piston syringe pumps and internal force sensor, syringe retainer, microprocessor, and LCD screen display. A foot pedal and power cord are also included; the user controls the epidural needle placement verification by use of the LCD user interface and optionally the foot pedal. The tray of single-use disposable supplies includes an external in-line fluid pressure sensor, a 20 mL plastic syringe, tubing set and an adapter that limits use of the disposables to a single use. Both the CompuFlo Epidural and the reference device, the CompuFlo Infusion Pump use the same technology to control the infusion according to the operator's preferences.
Performance Data
Testing of the CompuFlo Epidural device was carried out to meet elements of FDA's Draft Guidance Total Product Life Cycle: Infusion Pump-Premarket Notification [510(k]). Performance of the device and controlling software was evaluated via non-clinical testing, addressing such subjects as syringe plunger travel distance, volume dispensed, flow rates, and the accuracy of displays monitoring pressure at the needle tip. The results of these tests demonstrate that the device is as safe and as effective, and performs as well as, if not better than, the predicate device. Testing was conducted at various flow rates and head pressures to ensure that the instrument not only functions at nominal conditions but also at the extreme limits of the instrument's specifications. Bench data demonstrated that the CompuFlo Epidural has substantially equivalent performance as the predicate device.

Clinical Study
CompuFlo Epidural was evaluated in a prospective, randomized, parallel group, multicenter, pivotal study. The purpose of this pivotal study was to demonstrate the performance of the CompuFlo® Epidural Computer Controlled System for the epidural
6
space verification when compared to the loss of resistance technique (LOR). The primary objective of the COMPASS study was to determine whether the success rate of performance of lumbar epidural anesthesia with the CompuFlo Epidural to identify the epidural space is equivalent to performance of lumbar epidural anesthesia with the LOR technique. A total of 400 subjects were enrolled at 6 US clinical centers, of which two-hundred-forty subjects (240) required epidural procedure as part of the chronic pain management and one-hundredsixty (160) required epidural procedure for acute pain management during labor and delivery. Twelve (12) subjects (3% of the total population enrolled) did not have epidural procedure performed, so total of 388 procedures were performed as part of the study. The study data demonstrated the performance of the CompuFlo Epidural space verification. The primary outcome hypothesis that the Experimental Procedure Group (EPG) is noninferior to the Standard Care Group (SCG) with respect to the primary endpoint of successful performance of lumbar epidural procedure, where the non-inferiority margin (delta) is an absolute difference of 1 percent has been met.
Based on the nonclinical and clinical tests conducted, it was demonstrated that the CompuFlo Epidural device is as safe, as effective and performs as well as or better than the legally marketed device identified above.

Milestone's CompuFlo Epidural Computer Controlled Anesthesia System and the primary predicate Epidrum have the same intended use of verifying the placement of the epidural needle in the epidural space. The CompuFlo Epidural Controlled Anesthesia System additionally achieves the primary intended use in real-time whereas Epidrum, the predicate device does not. In addition, CompuFlo Epidural Controlled Anesthesia System is specifically indicated for patients over the age of 18 years old, which was established based on the COMPASS Clinical study, whereas the Epidrum was indicated for use in adults. The aforementioned difference is not critical to the intended therapeutic or diagnostic use of the device and the differences do not affect the safety and effectiveness of the device when used as labeled.
Both devices also have similar technological characteristics of using pressure sensing based on the well-known and widely used loss of resistance technique;difference between CompuFlo Epidural Controlled Anesthesia System and Epidrum is technology that is used the provide visual and audio indication that the needle has entered the epidural space CompuFlo Epidural Controlled Anesthesia System uses computer controlled objective measurement of the pressure changes at the tip of the needle, whereas Epidrum relies on the subjective audio and visual indication of the pressure changes. As stated above, differences are not critical to the intended therapeutic or diagnostic, use of the device, and the differences do not raise different questions of safety and effectiveness of the device when used as labeled. Furthermore once Health Care Provider (HCP) verifies the epidural needle placement in the lumbar epidural space, the CompuFlo® Epidural is disconnected and the HCP continues with the medical procedure. The Epidrum indications for use does not
8
address this step, however from the labeling/instructions for use that step is also completed with the Epidrum, thus there is no difference.
The CompuFlo Epidural uses an in-line fluid pressure sensor to accurately measure the pressure at the needle, which provides visual and audio indication that the needle has entered the epidural space. In comparison, the Epidrum uses a small pressure chamber that provides a visual indication that the needle has entered the epidural space. Although the method of pressure sensing is different, both provide feedback to the user regarding the loss of pressure as the needle enters the epidural space. The pressure sensor in the CompuFlo Epidural provides an objective and accurate pressure measurement to the user. In addition, FDA has cleared similar pressure sensing technology in the company's reference CompuFlo device (K053554). As such, any differences in technological characteristics do not raise different questions of safety or effectiveness. Furthermore, bench testing and clinical study data have demonstrate substantially equivalent performance. Accordingly, the CompuFlo Epidural is substantially equivalent to the primary predicate Epidrum.
