This article sets out the full specification: composition, sterilisation, sizes, handling profile and documentation, so surgical and procurement teams can evaluate it against their requirements without a sales call.<\/p>\n<h2>Composition and Material Identity<\/h2>\n<p>DECOLL is produced from ultra-pure Type I bovine collagen sourced from controlled tissue. The purification sequence removes non-collagenous proteins, lipids and cellular residue, leaving a fibrillar collagen matrix that mirrors the structural protein of native dura mater. Because the material identity is the same, host fibroblasts recognise and populate the scaffold without a preparatory inflammatory phase.<\/p>\n<p>No polymer component is present. The membrane is a natural protein matrix, and that is a deliberate design decision rather than a manufacturing limitation.<\/p>\n<h2>DECOLL Collagen Dura Membrane Sizes<\/h2>\n<p>Four square formats are available, each individually sterile-packaged with lot traceability and expiry marking.<\/p>\n<table>\n<thead>\n<tr>\n<th>Referans Kodu<\/th>\n<th>\u00dcr\u00fcn Detay\u0131<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>DCL2525<\/td>\n<td>DECOLL Collagen Dura Membrane 2.5 x 2.5 cm<\/td>\n<\/tr>\n<tr>\n<td>DCL5050<\/td>\n<td>DECOLL Collagen Dura Membrane 5 x 5 cm<\/td>\n<\/tr>\n<tr>\n<td>DCL7575<\/td>\n<td>DECOLL Collagen Dura Membrane 7.5 x 7.5 cm<\/td>\n<\/tr>\n<tr>\n<td>DCL100100<\/td>\n<td>DECOLL Collagen Dura Membrane 10 x 10 cm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The range covers focal repairs through to expansive duraplasty. Consequently, departments can align stock with their actual case mix and reduce waste from cutting down oversized sheets.<\/p>\n<h2>Sterilisation and Presentation<\/h2>\n<p>Each membrane is terminally sterilised by gamma irradiation at a validated dose that achieves sterility without denaturing the collagen. The product is supplied ready to use. No rehydration, chemical activation or preparation time is required, which matters in emergency neurotrauma where minutes are not available.<\/p>\n<h2>Key Features<\/h2>\n<ul>\n<li><strong>Biodegradable and resorbable.<\/strong> Gradually absorbed and replaced by the patient&#8217;s own connective tissue, so no removal procedure is needed.<\/li>\n<li><strong>CSF barrier.<\/strong> An impermeable pore structure resists cerebrospinal fluid transit.<\/li>\n<li><strong>High tensile strength.<\/strong> Resistant to tearing during suturing and manipulation.<\/li>\n<li><strong>Dual-surface usability.<\/strong> Either face may be placed against tissue.<\/li>\n<li><strong>Ready to use.<\/strong> Open the package and place.<\/li>\n<li><strong>Gamma sterilised.<\/strong> Sterility without compromising collagen quality.<\/li>\n<\/ul>\n<h2>Handling in Theatre<\/h2>\n<p>DECOLL balances structural strength with pliability. Surgeons trim the membrane to size with standard surgical scissors, position it with forceps, and either suture it into the dural edge or apply it as an onlay. Moreover, the sheet resists curling, fragmentation and shrinkage during handling, and it maintains its properties in contact with blood, irrigation and instruments.<\/p>\n<p>Visual clarity and tactile feedback support precise placement under microscope or loupe magnification, including in deep or narrow corridors.<\/p>\n<h2>Klinik Uygulamalar<\/h2>\n<p>The <strong>DECOLL collagen dura membrane<\/strong> is intended for dural repair and reconstruction in cranial and spinal neurosurgery. Typical settings include tumour resection, traumatic dural defects, spinal decompression, and duraplasty following decompressive craniectomy. In each case the membrane serves as an immediate barrier and a scaffold for host tissue regeneration.<\/p>\n<h2>Certification and Testing<\/h2>\n<p>DECOLL carries CE certification, and manufacturing conforms to <a href=\"https:\/\/www.iso.org\/\" target=\"_blank\" rel=\"noopener\">ISO 13485<\/a> for medical devices, which supports consistent quality, traceability and regulatory compliance across the product lifecycle. Biocompatibility testing follows the ISO 10993 series and covers cytotoxicity, sensitisation, systemic toxicity and implantation response. Additionally, the collagen matrix has been evaluated for mechanical durability, absorption behaviour and tissue integration.<\/p>\n<p>A comprehensive technical file and quality assurance documentation are available on request for institutions and surgeons requiring added transparency for procurement approval.<\/p>\n<h2>DECOLL and DURASHEET<\/h2>\n<p>Desu offers a second membrane, <a href=\"https:\/\/desu.tr\/tr\/urun\/durasheet-collagen-dura-membrane\/\">DURASHEET<\/a>, built on the same >99.9% pure Type I bovine collagen specification with a handling profile suited to contoured surfaces. Teams frequently stock both and select per case. Full details of the range are published at <a href=\"https:\/\/desu.tr\/tr\/urun\/dura-grafts\/\">desu.tr\/<\/a>.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<h3>Which side of DECOLL faces the brain?<\/h3>\n<p>Either. The membrane offers dual-surface usability, so no orientation step is required during placement.<\/p>\n<h3>Does DECOLL require suturing?<\/h3>\n<p>No. It may be applied directly as an onlay, but it can be sutured where the surgeon prefers a defined closure line.<\/p>\n<h3>How do we obtain evaluation samples?<\/h3>\n<p>Sample requests, CE documentation and pricing enquiries are handled by our clinical and commercial team at <a href=\"mailto:sales@desu.tr\">sales@desu.tr<\/a>.<\/p>\n<h2>Storage, Shelf Life and Stock Rotation<\/h2>\n<p>Each DECOLL sheet is supplied individually sterile-packaged with the lot number and expiry date printed on the package. Storage is at ambient conditions as specified in the instructions for use, with no refrigeration requirement, which simplifies theatre stock management and emergency trolley placement.<\/p>\n<p>Individual packaging supports single-case opening. Consequently, stock rotation is straightforward and the waste associated with multi-unit packs does not arise. For departments running a par level system, the lot marking on every unit makes vigilance reporting and recall traceability simple to administer.<\/p>\n<h2>Ordering and Reference Code Guidance<\/h2>\n<p>Most departments find that a mixed profile works better than a single format. As a starting point, higher par levels of DCL2525 and DCL5050 cover routine volume, DCL7575 is ordered against the scheduled list, and a minimum quantity of DCL100100 is held for emergency decompressive work.<\/p>\n<p>Our commercial team can build this profile from your case mix. Send a twelve-month activity summary to <a href=\"mailto:sales@desu.tr\">sales@desu.tr<\/a> and we will propose par levels, reference codes and pricing for your market.<\/p>\n<h2>What Is Not Claimed<\/h2>\n<p>Desu states what its documentation supports.
