Deflect to Protect®

ArmourSorb® is the durable and absorbent surgical shield that protects tissue abrasion from high-speed surgical instruments.

"As a surgeon I take every step to protect my patients and my staff in the operating room... and using the innovative ArmourSorb® drill resistant sponges in conjunction with a high speed drill to lower the risk of complications during my skull base procedures is simply the next logical step."

ArmourSorb® FDA and CE Released For Tissue Protection

ASC received FDA 510(k) clearance for our new medical device, ArmourSorb®, on June 20th, 2013 and CE marking on May 29th, 2015. ArmourSorb® is a novel, patent pending deflective and absorbent neurosurgical device composed of an absorptive base material stitched to a protective surface layer to deflect surgical instruments, such as high-speed surgical drills.  See ArmourSorb® in use in a cadaveric evaluation.


ArmourSorb® is indicated for use by trained physicians during neurosurgical procedures to protect neural tissues from drying, abrasion, or contamination and to absorb fluids.

Conventional Patties Lack Durability

The destruction of conventional neurosurgical patties (sponges) may lead to:

  • Procedure failure
  • Gossypiboma
  • Challenges in the sponge/pattie accounting process
  • Increased duration of procedure

Conventional neurosurgical patties are not shielded to prevent the destructive contact of a high-speed drill burr - they can quickly wrap, perforate, and potentially eject debris back into the wound.   This contamination may require extensive celanup both inside and outside the wound to prevent foreign objects from being retained (gossypiboma).

ArmourSorb® is our newest advancement in soft tissue protection and was designed to prevent the potential for wrapping and spinning of a standard micro neurosurgical pattie when used in close proximity to a high speed drill burr.  ArmourSorb® is ideal for Surgical Training Programs or surgical procedures such as: Craniotomies, Acoustic Neuromas, Spinal Laminoplasties, Laminectomies, Foraminotomies, or anywhere soft tissue is involved. ArmourSorb combines the absorbency and moisture retention of traditional sponges on the tissue side with a proprietary deflective layer on the opposing side and is available in a variety of sizes to meet your surgical needs.

ArmourSorb® combines the softness and absorbency of a standard surgical sponge with an outer layer to help protect underlying tissue from surgical instruments, such as a high speed drill.  ArmourSorb® allows the benefits of traditional neurosurgical sponges and patties to be used in proximity to surgical instruments.
