About

The primary objective of this study is to evaluate the safety and efficacy of the Zip-stitch® Vaginal Cuff Closure System. This will be primarily done by measuring the frequency of implant passing following system use. Also assessed will be relevant safety and efficacy endpoints as compared to a two-to-one reference group.

Full description

This study is a prospective, blinded, randomized, controlled study to assess the safety and efficacy of the Zip stitch® System in maintaining vaginal cuff closure following minimally-invasive hysterectomy. Participating subjects will be randomized and evaluated for implant passing, successful cuff closure, healing, adverse events, dyspareunia, and pain. Blinded follow-up will involve in-person visits at one week and six weeks. There will be additional unblinded follow-up in person at six months post-operatively and by telephone at 12 months post operatively.

Enrollment: 59 estimated patients

Sex: Female

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

12. On anticoagulant therapy
13. Participation in another interventional trial
14. Pregnancy
15. Abnormal Papanicolaou test (PAP) results that have not been fully evaluated, or in the opinion of the investigator may indicate abnormal vaginal cuff healing
16. Co-morbidities that, in the opinion of the investigator, may indicate risk of abnormal vaginal cuff healing
17. Intra-operative: Bowel injury during laparoscopic hysterectomy procedure prior to attempted cuff closure
18. Intra-operative: Bladder injury during laparoscopic hysterectomy procedure prior to attempted cuff closure
19. Intra-operative: Cases in which surgeon cannot identify adequate tissue along the cuff to apply suture laparoscopically
20. Intra-operative: Cases requiring conversion to laparotomy prior to study intervention
