Brief Summary:

ZSX Medical completed enrollment in its First in Human Ease of Use study in May of 2017, in Monterrey Mexico. The purpose of this study is to demonstrate the ease of use of Zip-Stitch™, to generate first in human data, and to refine surgical technique of the device.

Ten subjects were enrolled and received total laparoscopic hysterectomies, including vaginal cuff closure with the Zip-Stitch™ system during their otherwise standard care. Procedures took place over the course of one week. Subjects had in person follow-up appointments at 1 and 6 weeks. Subjects are continuing follow-up through a one-year extension period which will end in May 2018.

Arm Intervention/treatment
Experimental: Single Study Site: UANL
As the only study arm, 10 enrolled subjects received vaginal cuff closure with the Zip-Stitch Soft Tissue Closure System as part of Total Laparoscopic Hysterectomy.
Device: Zip-Stitch Soft Tissue Closure System
The novel Zip-Stitch System employed a laparoscopic applicator, a series of bio-absorbable clips, and an application procedure to close the vaginal cuff during otherwise standard of care total laparoscopic hysterectomy.

Primary Outcome Measures :
  1. Device Ease of Use [ Time Frame: Immediately following procedure ]
    Ease of Use of the Zip-Stitch Soft Tissue Closure System during Total Laparoscopic Hysterectomy. Assessed following surgery by standardized surgeon interview.

Secondary Outcome Measures :
  1. Vaginal Cuff Closure [ Time Frame: During procedure. ]
    Assessment of quality of vaginal cuff closure following uterine excision. Performed by surgeon as operative standard of care.

  2. Vaginal Cuff Closure Time [ Time Frame: During Procedure. ]
    Procedural time from uterine excision to successful vaginal cuff closure.

  3. Total Surgical Time [ Time Frame: During Procedure. ]
    Total procedural time.

  4. Device Use Learning Curve assessed with a Surgeon Survey [ Time Frame: Assessed immediately following study completion during surgeon survey. ]
    Investigation of change in effectiveness of device implementation as assessed by change in efficiency of device use.

  5. Sexual Discomfort [ Time Frame: Assessed at 1 and 6 week follow-up visits. ]
    Measurement of subject discomfort during sexual activity following completion of surgical procedure. Assessed with 1-10 scale (1 = No Pain, 10 = Most Pain).
