Brief Summary:

NERv's traditional feasibility clinical trial is a multi-center, pre-market, single-arm, and non-randomized trial. This study will involve the retrospective analysis of prospectively collected data. The trial is intended to establish the safety of NERv's Inline Device and collect preliminary data to illustrate the change in pH and electrical conductivity during normal postoperative recovery and in the event of a complication.

The purpose of NERv's feasibility study is to establish a clinical model that shows the progressive change in pH and electrical conductivity during a normal post-operative recovery and in the event of an anastomotic leak in colorectal, hepatobiliary (HPB), trauma, and general surgery patients. Upon analyzing data collected from NERv's Inline Device, a clinical model of change in pH and conductivity over time will be created. The clinical model can be used in future stages to determine if a complication is developing. For instance, boundaries (reading thresholds) can be established to detect a complication when readings exceed such boundaries.

Arm Intervention/treatment
Experimental: Subjects with NERv's Inline Device Attached
This arm contains subjects which will have NERv's Inline Device attached to their peritoneal drain after abdominal surgery.
 Device: NERv's Inline Device
NERv's Inline Device is comprised of multiple sensors. It attaches in line to existing catheters or peritoneal drains that are currently approved for medical use. This allows the device to measure the pH and electrical conductivity of effluent fluids that are drained through peritoneal drains.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change in pH of Peritoneal Fluid [ Time Frame: A clinical model of change in pH over time will be established once the study is completed (up to 18 months) ]
    NERv's Inline Device will be collecting continuous pH measurements of effluent fluid in abdominal surgery patients during normal recovery and in the event of a complication

  2. Change in Electrical Conductivity of Peritoneal Fluid [ Time Frame: A clinical model of change in electrical conductivity over time will be established once the study is completed (up to 18 months) ]
    NERv's Inline Device will be collecting continuous electrical conductivity measurements of effluent fluid in abdominal surgery patients during normal recovery and in the event of a complication

  3. Number of Subjects with Device Related Adverse Events [ Time Frame: The total number of device related adverse events will be established once the study is completed (up to 18 months) ]
    An adverse event assessment will be performed in accordance to ISO 14155 standards to determine the number of device related adverse events


Secondary Outcome Measures :
  1. Investigator Feedback on Device's Ease of Use [ Time Frame: Ease of use and impact on workflow will be established once the study is completed (up to 18 months) ]
    Ease of use and Impact on workflow will be evaluated by collecting responses to a questionnaire that will be filled out by the study team. The study team will evaluate the device's attachment, removal, setup, calibration, and their overall experience with the user interface on NERv's Mobile Application. The study team will be asked to rate their experience on a scale of 1-5, with 1 being very unsatisfied and 5 being very satisfied.

  2. Subject Feedback on Device's Comfort level [ Time Frame: Comfort level will be established once the study is completed (up to 18 months) ]
    Comfort level will be evaluated by collecting responses to a questionnaire that will be filled out by the subject. The subject will evaluate the device's weight, size, design, and their ability to sleep comfortably with the device attached. The subject will be asked to rate their experience on a scale of 1-5, with 1 being very unsatisfied and 5 being very satisfied.

  3. Estimate the economic benefit of the early detection of anastomotic leaks by contrasting the time of detection using NERv's Inline Device and Standard of Care [ Time Frame: The economic benefit of using NERv's Inline Device will be established once the study is completed (up to 18 months) ]
    Retrospective data analysis will be performed to estimate the economic benefit of early detection of anastomotic leaks in patients undergoing gastrointestinal procedures by comparing the time of detection using NERv's Inline device and the time of detection using standard of care
