Overview

NERv's early feasibility clinical trial is a first-in-human, multi-center, pre-market, non-randomized clinical trial intended to evaluate the safety and collect preliminary data necessary for the detection of clinical post-operative anastomotic/intraperitoneal leakages. NERv's Inline Device attaches to existing catheters or peritoneal drains that are currently being used in the medical industry. This allows the device to measure the pH and conductance of intraperitoneal fluids that typically get drained through peritoneal drains. The purpose of NERv's feasibility clinical trial is to collect pH and conductance readings by analyzing peritoneal drainage fluid. Upon analyzing data collected from NERv's Inline Device a clinical model of pH and conductance will be created. The clinical model can then be used to determine if a complication is developing. For instance, boundaries (reading thresholds) can be established where if the signal goes outside the boundaries a complication could be identified. Specifically the ability to detect a post-operative complication known as anastomotic leakage; which is a dreaded complication associated with abdominal surgeries; will be the main focus of the study.

Outcomes

Primary Outcomes

Change in pH of Peritoneal Fluid

NERv's Inline Device will be collecting continuous pH measurements of fluid that travels across the peritoneal drain of bariatric surgery patients.

Time frame: A clinical model of change in pH over time will be established once the study is completed (up to 28 weeks).

Change in Conductance of Peritoneal Fluid

NERv's Inline Device will be collecting continuous conductance measurements of fluid that travels across the peritoneal drain of bariatric surgery patients.

Time frame: A clinical model of change in conductance over time will be established once the study is completed (up to 28 weeks).

Change in Temperature of Peritoneal Fluid

NERv's Inline Device will be collecting continuous temperature measurements of fluid that travels across the peritoneal drain of bariatric surgery patients.

Time frame: A clinical model of change in temperature over time will be established once the study is completed (up to 28 weeks).

Number of Subjects with Device Related Adverse Events

an adverse event assesmtent will be performed in accordance to ISO 14155 standards to determine the number of device related adverse events.

Time frame: The number of device related will be established once the study is completed (up to 28 weeks).

Secondary Outcomes

Investigator and Subject Feedback on Device's Ease of Use and Comfort level

Ease of use and comfort levels will be evaluated by collecting responses to a questionnaire that will be filled out by both the investigator/nurse and the subject.

Time frame: Overall comfort level and ease of use will be established once the study is completed (up to 28 weeks).
