Intended Use

Intended for irrigation and fluid warming in laparoscopic procedures, and distention, fluid warming, and volume/deficit measurements in endoscopic procedures within gynecology, and orthopedic disciplines.

Device Story

FluidSmart is a rolling, electro-mechanical unit for endoscopic/laparoscopic procedures. It uses a peristaltic pump to pressurize irrigation fluids (saline, lactated ringer's, glycine, sterile water) and infrared heating for fluid warming. Input data includes temperature and pressure sensor readings, plus weight data from load cells on fluid bag hooks and suction canisters. A touch-screen processor provides closed-loop control, adjusting pump speed and warming power. Output includes warmed, pressurized fluid delivered to the surgical site and real-time fluid volume/deficit measurements. Used in OR settings by clinicians to maintain distention and irrigation; pressure relief valves in disposable tubing sets ensure safety. Benefits include precise fluid management and thermal regulation, aiding visualization and surgical outcomes.

Clinical Evidence

No clinical testing was conducted. Substantial equivalence is supported by non-clinical design verification testing, including software verification and tubing set verification.

Technological Characteristics

Electro-mechanical device; infrared fluid heating; peristaltic pump for pressure generation; touch-screen interface; closed-loop control system. Disposable tubing sets include spikes, clamps, warming cartridges, and luer locks with integrated pressure relief valves. Operates at pressures up to 300 mmHg.

Indications for Use

Indicated for irrigation, fluid warming, distention, and volume/deficit measurement during laparoscopic and endoscopic procedures in gynecology, urology, and orthopedic disciplines.

#### PREDICATE (LEGALLY MARKETED) DEVICE SUBSTANTIAL EQUIVALENCE

Thermedx believes FluidSmart® is substantially equivalent in terms of safety and effectiveness to the following predicate (legally marketed) devices:

- 1. Primary: Thermedx Fluid Management System (K133799)
- 2. Secondary: Smiths Medical's NormoFlo® Irrigation Warmer Model H-1129 (K072080)

#### IV. REFERENCE DEVICE

Kosin Technologies' Piggyback Irrigating System (K040094) used as a reference as to clinicians' current utilization of 300 mmHg pressure in urology procedures.

#### V. DEVICE DESCRIPTION

FluidSmart® is intended for irrigation, distention, fluid warming, and fluid volume/deficit measurements in endoscopic procedures within gynecology, urology, and orthopedic disciplines. Fluids commonly used include 0.9% saline, lactated ringer's solution, 5% mannitol, 1.5% glycine, and sterile water.

The main unit is mounted on a rolling stand which houses the technology used to warm the fluids and the peristaltic pump used to pressurize the fluids. A touch-screen operated processor provides closed loop controls for fluid warming and pumping. The processor monitors temperature and pressure sensors to adjust warming power and pump speed as required. Load cells attached to the fluid bag hooks and suction canister ring allow the processor to monitor fluid levels pumped to and suctioned from the surgical site.

## Disposable Tubing Sets

Several versions of the disposable tubing sets are available. The LL0002 is an inflow tubing set used for endoscopic procedures with maximum fluid pressures up to 150 mmHg. The LL0004 is an inflow and outflow tubing set used for endoscopic procedures with maximum pressures up to 150 mmHq. The LL0006 is an inflow tubing set used for endoscopic procedures with maximum fluid pressures up to 300 mmHg. The tubing sets terminate in a luer lock fitting for use with existing hospital equipment, typically an endoscope. Each tubing set includes spikes for the fluid bags, tubing clamps, a cartridge for fluid warming, and a luer lock for connection to the surgical instrument or to a tube that connects

{5}------------------------------------------------

to the surgical instrument. The luer lock features a pressure relief valve operating in a range specific to that model of tubing set.

#### VI. INDICATIONS FOR USE

FluidSmart® is intended for irrigation and fluid warming in laparoscopic procedures, and distention, fluid warming, and volume/ deficit measurements in endoscopic procedures within gynecology, urology, and orthopedic disciplines.

#### VII. TECHNOLOGICAL CHARACTERISTICS

## Technological Comparison:

The modified device, FluidSmart®, is essentially identical to the primary predicate device, Thermedx Fluid Management System, and substantially equivalent to the secondary predicate device with no fundamental technological differences. Essential design, the material, the chemical composition, the energy source, basic safety/essential performance, etc., are unchanged between the modified device and the primary predicate device. Other than the change to maximum fluid pressure for ureteroscopy going from 200 mmHg to 300 mmHg, there are no changes between the modified device and the primary predicate.

Packaging of the modified device and disposable tubing sets, sterilization means for the disposable tubing sets, expiration dating for the disposable tubing sets, and biocompatibility acceptability for the disposable tubing sets remain unchanged from the primary predicate as well.

Changes between the modified device and the primary predicate device relate to the ureteroscopy procedure pressure being increased from the currently cleared 200 mmHg to 300 mmHg utilized by the secondary predicate device.

#### NON-CLINICAL TESTS VIII.

Non-clinical testing performed including the following design verification testing: 1. Software verification testing. 2. Tubing set verification testing.

#### IX. CLINICAL INFORMATION

No clinical testing was conducted by or on behalf of Thermedx.

#### X. CONCLUSION

The proposed device is safe and effective and is substantially equivalent to the predicate devices. Any differences are minor and we believe they raise no new questions of safety and effectiveness.

All statements and representations set forth above regarding or related to "substantially equivalent" or "substantial equivalence" are in the limited context of the definition and purpose of substantial equivalence in the Federal Food, Drug, and Cosmetic Act, as amended, and applicable regulations of the Food and Drug Administration, and are not made in the context of, for any purpose related to, or as an admission against interest under, any other laws or regulations, including patent laws (whether in the context of patent infringement or otherwise).
