Cardiothoracic Surgery
At the core of Invengenx®’s superior performance is our proprietary elixP™ fixation methodology, which employs a modified glutaraldehyde formulation to crosslink the tissue. This advanced process results in a highly intact and crosslinked collagen matrix, ensuring that each patch is exceptionally supple, elastic, and biocompatible. Our years of dedicated research and development have culminated in a product that not only meets but exceeds the demands of complex cardiothoracic procedures.
