Covidien’s “World First” Laparoscopic Knotless Suture Reload Launched

In short

Covidien has added to its growing bariatric surgery portfolio with the news that its V-Loc™ knotless suturing device is now available as a reload that works with the Company’s proprietary Endo Stitch™ and SILS™ Stitch suturing devices for multi-port and single-port laparoscopic surgery.

The company claims its new device can increase operating room efficiency during bariatric surgery and other procedures.


Covidien says that by combining proprietary automated needle-passing technology with a knotless suturing device, the V-Loc device for Endo Stitch and SILS Stitch devices offers distinctive benefits over hand suturing and conventional automated suturing options.

The V-Loc device for use with Endo Stitch has a unique barb and loop design, enabling faster suturing by eliminating the need to tie any knots and saving surgeons 35-42% of the time required to suture inside the body, according to a recent pre-clinical study.1 Compared to conventional suturing, the proprietary Endo Stitch™ suturing device can save 45-70% of laparoscopic suturing time, clinical studies show.2-5

Covidien’s comprehensive bariatric surgery portfolio was showcased at last week’s 29th Annual Meeting of the American Society for Metabolic & Bariatric Surgery (ASMBS).

Clinician comments

“Bariatric surgery requires a significant amount of surgical stapling and suturing to ensure anastomotic closure,” noted Dana D. Portenier, MD, Assistant Professor of Surgery, Duke University Medical Center. “The ability to suture internal tissue laparoscopically without the need to tie knots can help surgeons shorten one of the most labor-intensive tasks performed during bariatric surgery. As an early user of the Endo Stitch device with the V-Loc reload, I’ve been able to perform laparoscopic suturing with greater ease and efficiency than I previously could have using traditional devices that require knots.”

Company comments

“Covidien works closely with surgeons to develop devices that not only improve patient outcomes, but also make surgery easier, safer and more efficient. We believe that our new V-Loc knotless suturing reloads for minimally invasive surgery will help surgeons perform aspects of their procedures with greater efficiency,” said Paul Hermes, Vice President, Chief Technology Officer, Covidien Surgical Solutions. “Covidien is committed to the advancement of bariatric surgery technology and offers a full portfolio of products and services to support bariatric surgeons, their practices and patients.”
