ALLOWRAP® Amniotic Membrane

AlloWrap is a human amniotic membrane designed to provide a biologic barrier following surgical repair. The dual-sided membrane features two layers of amniotic tissue oriented with the epithelial layers facing outwards, eliminating application orientation restrictions.

  • Dual-sided epithelial layer allows for maximum tissue barrier opportunities as an on-lay and/or in wrapping tissue applications, i.e. to support the body’s natural ability to reduce adhesions in demanding spine, trauma & extremity, sports medicine, and other surgical applications.
  • Tissue remains in surgical site greater than eight weeks.1
  • Immune privileged2, non-expansive, pliable tissue that conforms and settles within the surrounding tissues to form a stable, thin, strong membrane barrier.
  • Moist (AlloWrap DS) or dry (AlloWrap Dry) configuration to aid in demanding surgical placement.
  • Room temperature storage, with two-year shelf life.

AlloSource Placenta Donation Program

AlloWrap is derived from human amniotic membrane from a donated placenta directly following childbirth.  The AlloSource Placenta Donation Program provides an opportunity for women who are pregnant to collaborate with AlloSource and their doctor to facilitate the recovery and donation of their placenta. Learn more here.

AlloWrap® for Spinal Procedures

Regardless of the surgical approach, both AlloWrap DS and AlloWrap Dry are ideal natural surgical barriers for spinal procedures. The dual-sided design of this amniotic membrane, when used as a surgical barrier, provides covering and protection from the surrounding environment to support the body’s natural ability to ease potential complications such as scaring, inflammation and adhesion, while potentially lessening the burden of dissection during revisions. AlloWrap DS has a moist, hydrated format that is especially suitable for endoscopic and minimally invasive surgical applications, whereas AlloWrap Dry is dehydrated for precision open-surgical placement.

AlloWrap features a wide variety of benefits to alleviate common issues of spinal surgery.

  • Dual-sided epithelial layers provide an optimal surgical barrier for spinal procedures.
  • AlloWrap remains in the surgical site greater than eight weeks1, as compared to alternative therapies that quickly get absorbed by the body before they can realize the benefits of a surgical barrier.2
  • Immune privileged3, non-expansive, pliable tissue that conforms and settles within the surrounding tissues to form a stable, thin, strong membrane barrier.
  • Stored at room temperature and easy to place standalone, or with sutures to control migration.
