Ceterix Orthopaedics Awarded New Patent for Circumferential Suturing Method in Meniscus Repair

Ceterix® Orthopaedics, Inc., a leader in the development of
cutting-edge surgical tools for orthopaedic surgeons, today announced
the issuance of U.S. Patent No. 10,004,492 related to the company’s
method of placing a suture around a tear to repair a damaged meniscus,
adding to the company’s already expansive intellectual property

Ceterix’s new patent further protects the company’s technology enabling
surgeons to arthroscopically repair soft tissue injuries in the knee
using minimally invasive techniques. This is the second set of method
claims describing Ceterix’s proprietary Circumferential Compression
Stitch (CCS), a suture method that provides uniform, anatomic
compression of meniscus tears that was not possible to do previously
given the tight constraints of the knee.

“Whether you are setting a broken bone or suturing a laceration,
injuries heal best when the tissue edges are perfectly lined up
and repaired without gaps,” says Dr. Justin Saliman, founder and chief
medical officer of Ceterix. “For the first time, orthopaedic surgeons
can now apply this principle to meniscus tears with NovoStitch®
Meniscal Repair Systems. We believe that by enabling simultaneous
compression of the femoral and tibial sides of meniscus tears, the
Ceterix technology can provide surgeons with greater confidence to
repair tears that would have previously been considered non-repairable.”[i],[ii]

“The invention of delivering a Circumferential Compression Stitch within
the tight constraints of the knee may be the biggest innovation in
meniscal repair in the last 15 years,” says John McCutcheon, president
and CEO of Ceterix. “We are committed to expanding options for surgeons
to preserve the meniscus and protect normal knee function in their

The meniscus is a crescent of soft cartilage resting between the femur
and tibia that cushions the knee and is surrounded by critical nerves,
arteries and cartilage. Ceterix’s NovoStitch Meniscal Repair Systems
enable surgeons to work within this tight compartment to place a
stabilizing circumferential compression stitch around a meniscus tear.
The circumferential compression stitch is the only meniscus repair
technique that treats the femoral and tibial sides of a tear
simultaneously, enabling the repair of injuries that may previously have
required partial or complete removal of this important structure.

Arthroscopic surgery is a minimally invasive procedure in which an
orthopaedic surgeon treats the damaged joint through small incisions
using specialized tools and guided by a tiny camera called an
arthroscope. Meniscus surgery is the most common arthroscopic procedure
in the United States, with roughly one million performed annually.[iii],[iv]

Ceterix Orthopaedics develops surgical tools that fill unmet clinical
needs for physicians who treat soft tissue joint injuries such as
meniscus tears. Founded in 2010 with the vision of improving outcomes of
arthroscopic procedures, Ceterix’s novel meniscal repair system enables
surgeons to place suture patterns that were previously only possible in
open procedures, or not at all. The NovoStitch® Pro
Meniscal Repair System has received 510k clearance in the United States
and is indicated for approximation of soft tissue in meniscal repair
procedures. The company is based in Fremont, Calif., and is backed by
investors Versant Ventures, 5AM Ventures and CRG. For more information,
