Outcome Measures

Primary Outcomes (6)

  • Number of Participant That Experience Adverse Procedure and/or Device Effects

    All participants were monitored for adverse device effects (procedure and device related adverse events) from implantation of the TransLoc electrodes through electrode removal.

    Implantation through hospital discharge or Day 7, whichever comes first.

  • Number of Study Participants That Experience Successful Placement of Two Electrodes in Each Hemi-diaphragm

    Successful placement of two TransLoc electrodes in each hemi-diaphragm of the study participants during the operative procedure. Success was the ability to perform stimulation postoperatively using the implanted electrodes to effectively stimulate the patients for ventilation as evidenced by the ability to successfully achieve the predicted tidal volume.

    Postoperatively on Day 1

  • Device Stimulation Using Four Electrodes Will Achieve the Predicted Tidal Volume for Study Participants

    Ability of device stimulation using four electrodes to achieve or exceed the percent of predicted tidal volume for all study participant.

    Postoperatively Day 1

  • Number of Study Participants in Which Daily Diaphragm EMG Was Successfully Measured.

    Ability to use the implanted electrodes to measure diaphragm EMG activity of both hemi-diaphragms for all study participants.

    Postop Day 1 through hospital discharge or Day 7, whichever comes first

  • Number of Study Participants in Which TransLoc Electrodes Remained in the Diaphragm Until Removed.

    Electrode stability was determined by using the electrodes to record tracings of the diaphragm EMG daily for at least a 10 minute period. The tracings were reviewed to determine diaphragm activity including characterization of diaphragm burst activity, breathing patterns and identification of apneic events, if any. The recordings also confirmed electrode stability (non-displacement and electrical integrity) during the period of temporary implantation.

    Postop Day 1 through hospital discharge or 7 days, whichever comes first

  • Number of Participants That Experienced Complete Removal of Entire TransLoc Electrode

    Number of study participants in which TransLoc electrodes were removed intact without device fragmentation or the occurrence of device or procedure related adverse events. Removal was performed by the healthcare provider by pulling electrodes from the percutaneous entry point. This was done in a similar fashion as a temporary cardiac pacing wire with a slow steady pull in a straight non oblique line.

    Postop Day 1 through hospital discharge or Day 7, whichever comes first

Secondary Outcomes (3)

  • Comparison of Percentage of Predicted Tidal Volumes Measured.

    Postop Day 1

  • Number of Participants That Achieve a Tidal Volume of at Least 6cc/kg of Predicted Body Weight (PBW)

    Postop Day 1

  • Number of Participants With Successful Measurement and Characterization of Diaphragm Activity.

    Postop Day 1 through hospital discharge or Day 7, whichever comes first

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient is undergoing a surgical procedure with expected admission to the hospital.
  • Patient is undergoing a laparoscopic, open abdominal, or open chest surgical procedure that allows access to the diaphragm.
  • Negative pregnancy test if the patient is a female of child-bearing potential.
