Intended Use
The X-FLO Fluid Management System is intended to: · Warm and pump fluid, via intravenous (IV) bags or fluid bottles, to provide fluid distention and flushing of the uterus for gynecology procedures. The device can also measure fluid deficit of the surgical procedure. · Warm and pump fluid, via IV bags or fluid bottles, to provide fluid distention and flushing of the bladder and kidneys, or general distention and flushing, for urological procedures. The device can also measure fluid deficit of the surgical procedure. · Warm and pump fluid, via IV bags or fluid bottles, to provide fluid distention and flushing of the shoulder, knee, or other small joints for orthopedic procedures. The device can also measure fluid deficit of the surgical procedure.
Device Description
The X-FLO Fluid Management System ("X-FLO") (P/N 01910), with an optional deficit module (P/N 01601) is intended for fluid distention, fluid warming, and fluid volume/deficit measurements, as well as external suction regulation pertaining to deficit measurements for diagnostic and/or operative endoscopic procedures within gynecology, urology, and orthopedic disciplines. The X-FLO utilizes a touchscreen user interface and performs fluid pressurization, warming, and volume/deficit monitoring functions. More specifically, the device employs a peristaltic pump to pressurize and deliver fluid to the surgical site for distending and continually flushing the surgical site for visualization purposes, utilizes infrared lamps to optionally warm the fluid to body temperature, and uses fluid bag weight to monitor fluid inflow. Regarding the optional deficit monitoring function, the device utilizes external suction to return fluid from the surgical site. The X-FLO monitors and adjusts the vacuum level to the operator selected setpoint by opening the suction line to atmosphere if necessary. Once the fluid is returned from the surgical site, the single-use deficit cartridge measures the fluid volume collected, prior to transfer to fluid collection equipment and/or the hospital's waste disposal system. The X-FLO is controlled via a Graphical User Interface (GUI), wherein the user is guided to select a surgical discipline and a procedure type. Once selected, the user can input the desired setpoint within the established minimum and maximum parameters for that procedure type. As set forth below, the X-FLO can operate in Pressure Control (the default control, or X-Control. Each control view has defaults and adjustment ranges for fluid pressure, flow, temperature, deficit alarm, and external suction regulation. In addition to adjusting the fluid pressure setpoint via the GUI, the user may optionally utilize a foot pedal included with the X-FLO to temporarily increase the fluid pressure. By pressing the foot pedal, the user initiates an increase in fluid pressure. The increase is user configurable but can never exceed the maximum allowable fluid pressure for the procedure. When the user desires to have the fluid pressure return to the setpoint, the foot pedal is released.
More Information

Not Found

No
The description details a system based on peristaltic pumps, infrared lamps, weight sensors, and vacuum regulation, controlled by a GUI with user-defined setpoints. There is no mention of AI, ML, or any learning or adaptive algorithms. The software is described as "major" level of concern, which is common for medical devices with significant control functions, but doesn't inherently imply AI/ML.

No
The device is used for fluid management (warming, pumping, distention, flushing, and deficit measurement) during surgical procedures, primarily for visualization and maintaining the surgical field, not for directly treating a disease or condition. While fluid distention could be seen as part of a therapeutic procedure, the device itself is a surgical accessory rather than a standalone therapeutic device.

Yes

The device description explicitly states, "The X-FLO Fluid Management System... is intended for fluid distention, fluid warming, and fluid volume/deficit measurements, as well as external suction regulation pertaining to deficit measurements for diagnostic and/or operative endoscopic procedures." The phrase "for diagnostic and/or operative" indicates its use in diagnostics, and its ability to measure fluid deficit is part of this diagnostic function.

No

The device description clearly outlines hardware components such as a peristaltic pump, infrared lamps, a touchscreen user interface, and an optional deficit module with external suction and a single-use deficit cartridge. It also mentions a foot pedal accessory. These are physical components, not solely software.

Based on the provided information, the X-FLO Fluid Management System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use clearly states the device is for warming and pumping fluid for distention and flushing during surgical procedures (gynecology, urology, and orthopedics). While it measures fluid deficit, this is a measurement of fluid used and returned during the procedure, not a diagnostic test performed on a sample taken from the body.
  • Device Description: The description details a system for fluid delivery, warming, and volume/deficit monitoring during a surgical procedure. It does not describe any components or processes for analyzing biological samples (blood, urine, tissue, etc.) outside of the body.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples, using reagents, or providing diagnostic information based on the analysis of such samples. The deficit measurement is a procedural metric, not a diagnostic one.

Therefore, the X-FLO Fluid Management System is a surgical device used to manage fluid during procedures, not an IVD device used for diagnostic testing on biological samples.

IV. DEVICE DESCRIPTION

The X-FLO Fluid Management System ("X-FLO") (P/N 01910), with an optional deficit module (P/N 01601) is intended for fluid distention, fluid warming, and fluid volume/deficit measurements, as well as external suction regulation pertaining to deficit measurements for diagnostic and/or operative endoscopic procedures within gynecology, urology, and orthopedic disciplines.

The X-FLO utilizes a touchscreen user interface and performs fluid pressurization, warming, and volume/deficit monitoring functions. More specifically, the device employs a peristaltic pump to pressurize and deliver fluid to the surgical site for distending and continually flushing the surgical site for visualization purposes, utilizes infrared lamps to optionally warm the fluid to body temperature, and uses fluid bag weight to monitor fluid inflow.

Regarding the optional deficit monitoring function, the device utilizes external suction to return fluid from the surgical site. The X-FLO monitors and adjusts the vacuum level to the operator selected setpoint by opening the suction line to atmosphere if necessary. Once the fluid is returned from the surgical site, the single-use deficit cartridge measures the fluid volume collected, prior to transfer to fluid collection equipment and/or the hospital's waste disposal system.

The X-FLO is controlled via a Graphical User Interface (GUI), wherein the user is guided to select a surgical discipline and a procedure type. Once selected, the user can input the desired setpoint within the established minimum and maximum parameters for that procedure type. As set forth below, the X-FLO can operate in Pressure Control (the default control, or X-Control. Each control view has defaults and adjustment ranges for fluid pressure, flow, temperature, deficit alarm, and external suction regulation.

In addition to adjusting the fluid pressure setpoint via the GUI, the user may optionally utilize a foot pedal included with the X-FLO to temporarily increase the fluid pressure. By pressing the foot pedal, the user initiates an increase in fluid pressure. The increase is user configurable but can never exceed the maximum allowable fluid pressure for the procedure. When the user desires to have the fluid pressure return to the setpoint, the foot pedal is released.
