ProxiCor

Aziyo Biologics

ProxiCor is an extracellular matrix (ECM) used for pericardial closure and to repair endocardial structures. Reformation of the pericardium using ECM enables surgeons to re-establish this essential native anatomic structure.

ProxiCor™ for Pericardial Closure enables surgeons to re-establish the essential native anatomic structure of the pericardium.

ProxiCor for Pericardial Closure is used to restore the pericardium by providing a natural bioscaffold that allows the patient’s own cells to form a new pericardial layer.¹ ² Absence of the pericardial barrier often leads to scarring and the formation of adhesions between the heart and sternum, impairing normal heart function.¹ ³ ⁴ ⁵ ⁶ Reconstructing the pericardium facilitates less bleeding and re-exploration, safer re-entry, and may shorten operative times for redo. ⁴ ⁷ ⁸ Reformation of the pericardium using ECM enables surgeons to re-establish this essential native anatomic structure.¹

Benefits:

• Remodels over time to restore healthy, pericardial tissue¹

• Preserves the distance between the heart and sternum⁴

• May shorten operative times for redo procedures⁹

• Enables accurate identification of post-operative bleeding¹⁰

• Lacks the pro-inflammatory components of chemically fixed xenografts³

• May improve hemodynamics by restoring normal anatomy¹¹

ECM is our next-generation tool for repair of intracardiac structures. Regrowth and remodeling capabilities make it superior to inert patches that ultimately promote inflammation and scarring.

ProxiCor™ for Cardiac Tissue Repair is intended for use as an intracardiac patch or pledget for tissue repair (i.e. atrial septal defect [ASD], ventricular septal defect [VSD], etc.) and suture-line buttressing. It may be used to repair intracardiac tissues, damaged cardiac structures, or during procedures when cardiovascular prosthetics (such as valves) do not fit properly. ECM is ideal for intracardiac surgery based on its ability to structurally support repairs and remodel tissue. In cases such as ASD repair, ProxiCor for Cardiac Tissue Repair can effectively close a hole and generate new, healthy tissue in lieu of using objects such as nitinol plugs or synthetic patches. ECM is gradually replaced by native tissue as it remodels.

Benefits:

• Effectively closes holes and restores natural cardiac tissue

• Ideal for intracardiac repairs

• Encourages the body’s natural immune response, unlike synthetic grafts ¹ ²

• Allows capillary in-growth and infiltration³ ⁴ ⁵ ⁶

• Resists calcification⁷ ⁸ ⁹ ¹⁰
