Brief Summary:
The purpose of this study is to assess the safety and ease of use of a trocar placement access device (TPAD) to assist with obtaining peritoneal access with a Veress needle, and for placing a primary trocar, during laparoscopic surgery.

Condition or disease Intervention/treatment Phase
Laparoscopic Surgery Device: Trocar Placement Assist Device (TPAD) Not Applicable

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 9 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Device Feasibility
Official Title: Pilot Study to Establish Safety and Ease of Use of a Trocar Placement Access Device (TPAD) for Laparoscopic Surgery
Estimated Study Start Date : June 1, 2020
Estimated Primary Completion Date : June 1, 2021
Estimated Study Completion Date : July 1, 2021

Arm Intervention/treatment
Experimental: Trocar Placement Assist Device (TPAD)
Participants will receive investigational TPAD device during laparoscopic surgery
Device: Trocar Placement Assist Device (TPAD)
The TPAD is an experimental device used to assist with placement of Veress needle and trocar during laparoscopic surgery.

Primary Outcome Measures :
  1. Surgeon satisfaction survey [ Time Frame: up to 1 minute on day of surgery ]
    The surgeon will complete a LIKERT scale satisfaction survey related to the TPAD to assess its ease of use. Scale range 1-5 (higher scores correspond to higher satisfaction)

Secondary Outcome Measures :
  1. Time required to obtain peritoneal access and place primary trocar during laparoscopic surgery [ Time Frame: Up to 10 minutes ]
    Time from incision to successful placement of primary trocar will be measured and reported

  2. Number of Participants with Treatment-Related Adverse Events as Assessed by CTCAE v4.0 [ Time Frame: Continuous from start of surgery through postoperative day 7 ]
    Adverse events related to the surgery itself, or to the incision and skin around the incision where the TPAD is placed
