Novus Scientific Release: Hernia Publishes a Unique Three Year Pre-Clinical Study of Absorbable TIGR(R) Matrix Surgical Mesh Versus a Permanent Mesh
Published: Oct 06, 2011
SINGAPORE, Oct. 6, 2011 /PRNewswire/ -- Novus Scientific today announced the peer-reviewed publication of unique pre-clinical data on TIGR® MatrixSurgical Mesh the world's first long-term absorbable surgical mesh.
The study, which was presented Online First in Hernia - The World Journal of Hernia and Abdominal Wall Surgery, describes the results of three years of functional implantation of TIGR® Matrix versus a permanent mesh in a sheep model.
This is the longest preclinical evidence ever published on surgical mesh, and it reveals key differences in outcome when comparing TIGR® Matrix to a permanent mesh. As TIGR® Matrix was absorbed over time, it was replaced by connective tissue that had higher collagen content than that surrounding the permanent control mesh. Over time, the foreign-body response to TIGR® Matrix declined significantly while it remained persistent in the control group.
"AsTIGR® Matrixis the worlds first long-term absorbable mesh and also the first surgical mesh product with time-dependent mechanical characteristics, we wanted to substantiate how the unique design affects the tissue in terms of regenerated structure and stability." said Henrik Hjort, first author and co-inventor of TIGR® Matrix. "We believe that the dual-fibre mechanics and resultant gradually increasing compliance can lead to long-lasting results which are indicated by the lack of defect recurrences in this study. A range of clinical studies are underway to examine the results of repair using TIGR® Matrix in a variety of soft tissue reinforcement applications to further demonstrate the benefits to the surgical community."
As stated in the publication: "As the resorbable test mesh gradually degraded it was replaced by a newly formed collagen matrix with an increasing ratio of collagen type I/III, indicating a continuous remodeling of the collagen towards a strong connective tissue." Furthermore: "The general connective tissue layer formed was thicker around the test mesh compared to the control." Hjort H, et al. (2011) Hernia. doi: 10.1007/s10029-011-0885-y.
The study was performed at Biomatech, an independent contract research company that is part of the NAMSA group.
