Duramesh - Duramesh Lyo

Duramesh/Duramesh Lyo, previously called "AudioMesh Neuro" and "Lyomesh Neuro" respectively, is a biological, re-absorbable dura substitute consisting of a pericardium membrane, designed to provide high ease of use.

Duramesh is conserved in liquid while Duramesh Lyo is freeze-dried.

The product stands out due to the fast application, the easy handling, the versatile usage in terms of fulfilling the surgeon's needs and preferences, and the reliable treatment for the patient.

 

Membrane conserved in liquid - Duramesh

The conservation in liquid gives to the membrane a great handling since it comes already hydrated. The conservation liquid needs to be rinse in saline as described in the IFU.

 

Freeze-dried membrane - Duramesh Lyo

Duramesh Lyo is ready for use since it doesn't need to be rinse. It can be rehydrated directly in operating field.

More info

Duramesh/Duramesh Lyo is biological a dural patch totally reabsorbable. The membrane is made of an equine acellularized pericardium and it's processed to grant resistance, biocompatibility and easy handling. 

The membrane gets reabsorbed in about 3 months.  

 

Advantages

- Allows for the simple, time-saving Onlay application with the possibility to be sutured as well, if necessary

- BSE free

- Transparent to keep visual control

- Absorbable

- High tensile strength

- Liquid-tight to prevent CSF leakages

- Excellent biocompatibility

Indications

Duramesh/Duramesh Lyo 

Duramesh/Duramesh Lyo is indicated for dural replacement or reinforcement in neuro and spinal procedures.

Thanks to the manufacturing process developed and improved through years of experience, the membrane is easy to handle and fits defects even irregular anatomical structures. 

Despite the reduced thickness and the high transparency – important characteristics in several surgeries – Duramesh/Duramesh Lyo keeps a highly resistant structure and can be sutured without breaking.

For this reason, these membranes are suitable even in the operations with high CSF pressure, such as in cranial fossa.

Duramesh Lyo has been successfully used in the surgery treatment of Arnold Chiari malformations and it's part of a specific protocol developed by Neurologic Institute "Carlo Besta" (Milan, Italy)*
