What is TIGR®Matrix?

TIGR®Matrix is the world’s first long-term resorbable, 100% synthetic mesh, made from materials that have been in clinical use since the 1970s (lactide, glycolide, trimethylene carbonate). It’s unique technology consists of dual-stage degradation and full resorption.

Used by surgeons around the world

Over time TIGR®Matrix degrades and load is gradually transferred to the newly regenerated tissue during the remodeling phase resulting in new functional tissue.

Initial wound healing

Material rigidity ensures stability during initial wound healing.2


TIGR® Matrix develops more flexible mechanics that allow for movement during remodeling.1


After 36 months, the material is completely resorbed and replaced by well-structured collagen.1

The pre-pectoral procedure with Tigr® Matrix

  • The reconstruction is offered as a one or two stage procedure depending on clinical criteria, the need for adjuvant radio- and/or chemotherapy or other risk factors.
  • Complete coverage or anterior coverage of the implant with TIGR® Matrix is possible.
  • The pre-pectoral reduces pain as the pectoralis major muscle remains undisturbed and thus eliminates animation (e.g. jumping breast phenomenon) due to muscle contraction.
  • An implant is placed above the pectoralis major muscle and TIGR® Matrix supports and stabilizes the implant in place while promoting tissue repair and long-term soft tissue support.
  • The pre-pectoral procedure is a less invasive technique becoming more popular due to reduced post-operative pain and better quality of life for the patient.
  • A one-step reconstruction after a mastectomy is possible, allowing the patient to recover faster, have a better body image as well as satisfying aesthetic outcome.

The sub-pectoral procedure with Tigr® Matrix

  • The reconstruction is offered as a one or two stage procedure depending on clinical criteria, the need for adjuvant radio- and/or chemotherapy or other risk factors.
  • Cutting the pectoralis major muscle at the low insertion and placing the breast implant under the muscle flap is the standard approach.
  • Placing the implant behind the pectoralis major muscle may increase rates of acute and chronic post-operative pain due to muscle trauma and discomfort with any physical activity, a longer duration with drains, a higher rate of capsular contraction and implant displacement.
  • Implant malposition and lack of tissue in the lower pole increases risks of implant exposure.
  • To achieve coverage of the lower pole of the breast, TIGR® Matrix is sutured to the submammary fold and to the lower part of the pectoral muscle and laterally to the chest wall. Partial muscle coverage together with TIGR® Matrix allows for better predictability.
  • The introduction of TIGR® Matrix long-term resorbable synthetic mesh offers a solution to many of the shortcomings associated with muscle coverage.

Tissue integration and collagen deposition – revascularization

TIGR®Matrix is rapidly integrated into the surrounding tissue by deposition of new collagen and formation of new blood vessels.

Macro-porosity designed to allow tissue integration for tissue repair

Specifically designed for soft tissue repair and used by surgeons in reconstruction surgery.

TIGR®Matrix is a soft and pliable alternative when performing implant based breast reconstructions. Vital when performing both the pre-pectoral and sub-pectoral technique.

The untwisted multifilament fibers allow new tissue to integrate fully through the porous structure as well as inbetween each fiber.
