Intended Use

The TauTona Pneumoperitoneum Assist Device (TPAD) is intended for use in the upper left quadrant of the abdominal wall (i.e., Palmer's Point) with a Veress needle for the establishment of a pneumoperitoneum during laparoscopic procedures.

Device Story

Single-use device for laparoscopic surgery; assists Veress needle insertion at Palmer's Point. Device features pad with suction cup array, vacuum port, vacuum control button, and handle. Connects to hospital vacuum line; applies negative pressure to skin to stabilize tissue for needle insertion. Crescent shape allows device removal while Veress needle remains in situ. Used by surgeons in clinical settings. Benefits include stabilized access site and potential reduction in bruising compared to standard of care.

Clinical Evidence

Randomized clinical study (n=20; 10 TPAD, 10 SOC) at a U.S. academic center. Population: adults >18, BMI <35 kg/m2. Primary endpoint: device feasibility (surgeon questionnaire). Results: TPAD median score 4.0, non-inferior to SOC. Secondary endpoints (access time, insufflation time, adverse events) showed no statistically significant differences. No device-related SAEs. Bruising resolution times were comparable or favorable in the TPAD arm.

Technological Characteristics

Single-use, non-powered, manual device. Materials: biocompatible per ISO 10993-1. Principle: negative pressure via external hospital vacuum line. Form factor: crescent-shaped pad with suction cup array. No electrical components, software, or firmware.

Indications for Use

Indicated for patients undergoing laparoscopic surgery requiring pneumoperitoneum establishment via Veress needle in the upper left abdominal quadrant (Palmer's Point).

Regulatory Classification

Identification

A laparoscopic insufflator is a device used to facilitate the use of the laparoscope by filling the peritoneal cavity with gas to distend it.

### 510(K) SUMMARY

#### DEVICE DESCRIPTION

The TauTona Pneumoperitoneum Assist Device (TPAD) is a single use device used during laparoscopic surgical procedures. The device consists of a pad which contains an array of suction cups on one side; a port that attaches to a standard hospital vacuum line; a button to control vacuum to the suction cups; and a handle to allow user to manipulate the device. Suction is applied to the device to allow the user to manipulate (hold and pull on) the tissue around the Veress needle insertion site. The device is crescent in shape to allow removal of the device after use while the Veress needle remains in the patient.

### INDICATIONS FOR USE

The TauTona Pneumoperitoneum Assist Device (TPAD) is intended for use in the upper left quadrant of the abdominal wall (i.e., Palmer's Point) with a Veress needle for the establishment of a pneumoperitoneum during laparoscopic procedures.

### Clinical Data

A randomized clinical study consisting of two arms was performed at an academic center in the U.S. The purpose of this study was to evaluate the safety, effectiveness and ease of use of the TPAD for laparoscopic surgery when the Veress Needle was used to establish pneumoperitoneum. Study population included 20 individuals greater than 18 years old (age range 25 - 73 years old), with a BMI < 35 kg/m2 (range 21.6 - 34.8) requiring a laparoscopic surgery. Other demographics in the study included 55% white, 40% Hispanic/Latino and 5% Asian: 3 biological males and 7 biological females in the TPAD arm, while 5 biological males and 5 biological females were in the Standard of Care (SOC) arm. Ten (10) patients underwent laparoscopic surgery as otherwise planned, with their surgeon using the TPAD device to assist in placement of the Veress needle. Ten (10) additional patients underwent laparoscopic surgery following the SOC. Surgeons completed a questionnaire following the procedures to evaluate the device feasibility/ ease of use. All patients also completed surveys to assess patient satisfaction. The primary endpoint was device feasibility as measured by a surgeon questionnaire completed at the end of every surgery. Secondary endpoints included the time needed to obtain laparoscopic access using the device, time needed to complete insufflation, monitoring for adverse events, time to resolve bruising, and patient satisfaction on skin appearance/bruising as measured by patient surveys and photographs postoperatively. All surgeons were able to place the Veress needle using the TPAD at the 520-mmHg pressure. The surgeon questionnaire answers for both SOC (average range of 3.9 to 4.0) and TPAD (average range of 3.9 to 4.0) had a median of 4.0 for all responses. For all questionnaires, both SOC and TPAD were not significantly different from a theoretical median of 4.0 (Wilcoxon test). Also, the secondary endpoints did not have any statistically significant difference using unpaired t test.

There were no device related serious adverse events (SAEs). All other adverse events were deemed mild and were related to insertion site and skin handling bruising with complete resolution in the TPAD arm as follows: 6/10 subjects' bruising resolved within 3 days, 2/10 subjects between 4 - 6 days, 1/10 subject at 7 days and 1/10 subject at 19 days postoperatively. For the SOC arm bruising resolved within 3 days for 4/10 subjects, between 4 - 6 days for one subject and 5/10 subjects still had bruising at 7+ days postoperatively (one at 7 days, two at 7+ days, one at 8+ days, one at 9+ days and one at 16+ days).

### CONCLUSION

The subject device has the same intended use as the predicate, with similar technological characteristics. The differences in technological characteristics do not raise different questions of safety and effectiveness. Performance testing conducted on subject device demonstrate that is as safe and effective as the predicate device to support substantial equivalence.
