Ready-to-Use Dural Grafts: No Pre-Processing Explained

What “no pre-processing” means on a ready-to-use dural graft: how it applies to DURASHEET and DECOLL, what it does not cover and how buyers can compare.

A ready-to-use dural graft is supplied so that it can be applied without a separate preparation step. DESU’s DURASHEET and DECOLL need none: the membrane can be used after it is removed from its packaging, with no additional pre-processing. The instructions for use (IFU) remain the reference for handling at surgery.

Key takeaways

• DURASHEET and DECOLL are both ready to use, with no pre-processing before application.
• “No pre-processing” describes preparation of the product, not the surgical decisions about size, placement or fixation.
• It is a product description, not an outcome claim, and the IFU remains the reference for handling.
• When comparing grafts, read what each IFU requires rather than relying on the phrase alone.

Both products belong to the DESU range of dural grafts. Our earlier article on ready-to-use grafts and OR workflow follows the package from shelf to field for distributors and OR leaders.

What does “no pre-processing” mean on a dural graft?

It means the product does not need a preparation stage before it is applied:

• DURASHEET is supplied so that it can be used without pre-processing after it is removed from its packaging.
• DECOLL is supplied ready to use without pre-processing after removal from its packaging, so it can be applied without an additional preparation step.

Pre-processing is “None” in the technical data for both products, and the absence of this step is a practical feature of each.

What kinds of preparation can other graft types involve?

Preparation depends on what a graft is and how it is supplied, so it varies by graft type:

• Autologous grafts are harvested from the patient during surgery, then cleaned and shaped before use.
• Some preserved or dried graft materials call for rinsing or rehydration, as set out in their own IFU.
• Grafts supplied ready to use have no such stage in their preparation, although each product’s IFU still governs how it is handled.

None of this ranks one type above another. The surgeon chooses a graft for the repair, and a preparation step may be entirely acceptable in that choice. What matters is that the team knows in advance what, if anything, the chosen graft needs.

What does “no pre-processing” not mean?

The phrase is narrower than it may sound. It describes the product’s preparation only, and does not cover:

• Surgical decisions. Graft size, positioning and whether to suture are still decided by the surgeon.
• Routine checks. The package, label, product, size and date are still checked as hospital policy requires.
• Handling instructions. The IFU applies to any step at the sterile field.
• Storage and shelf life. These are stated on the label, and the phrase says nothing about them.
• Clinical results. It is a statement about supply format, and it should never be presented as a claim about outcomes.

How do DURASHEET and DECOLL compare?

On preparation they are the same. Their differences lie elsewhere, as the table shows.

Since preparation does not separate them, the surgeon’s preferred closure technique is the more useful guide. Both are CE marked and made under ISO 13485.

How does gamma sterilisation relate to “ready to use”?

The two statements answer different questions. “Ready to use” concerns preparation. “Gamma sterilised” concerns how the product was sterilised. A product supplied sterile does not need to be sterilised by the hospital, which is one reason the two are often mentioned together.

Radiation sterilisation of health care products is covered by the ISO 11137 series. Our article on gamma sterilisation of collagen dura membranes goes into the method.

What does it mean for the theatre team?

With no preparation stage to plan for, the team’s attention shifts to having the right product and size available. Both membranes come in four sizes and share these uses:

• Dural defects after spinal tumour surgery.
• Dural defects after trauma.
• Meningocele and myelomeningocele.
• Surgical dural defects associated with lipoma.

Practically, that means knowing which sizes each surgeon tends to ask for, keeping them where they are used, and knowing whether the surgeon wants the option of suturing. There is also no preparation step to assign to anyone in the plan for the case, so the routine stays the same whether the graft was planned or requested during surgery.

How should buyers compare this claim across products?

“Ready to use” is an easy phrase to repeat, so check what sits behind it. When comparing grafts, a value analysis team can ask for each product:

• What does the IFU require between opening the package and applying the graft?
• Does the technical documentation state pre-processing explicitly, as a line item?
• Is the statement the same for every size in the range?
• Does anything in the preparation depend on equipment or solutions the hospital must supply?

Comparing IFU text keeps the discussion accurate. For DURASHEET and DECOLL, “no pre-processing” covers all four sizes.

Frequently asked questions

Do DURASHEET or DECOLL need to be soaked before use?

Neither product requires pre-processing. If your team has a specific question about wetting or positioning the membrane at the field, the IFU supplied with the product is the reference.

Is “ready to use” the same as “sterile”?

No. They are separate statements. Ready to use means no pre-processing is required, while gamma sterilised describes how the membrane is sterilised. DURASHEET and DECOLL are both.

Does no pre-processing mean the graft saves theatre time?

DESU makes no time claim. For DURASHEET, the absence of a pre-processing step simplifies surgical use. Any time comparison should come from a hospital’s own observation.

Does the statement apply to every size?

Yes. Each product is ready to use with no pre-processing in all four sizes, from 2.5 × 2.5 cm to 10 × 10 cm.
