COLLAPAT® II is a haemostatic bone substitute biomaterial presented in a sponge form.
It is composed of a collagen structure in which ceramised hydroxyapatite granules are dispersed.
The granules of hydroxyapatite give the material its osteoconductive properties. The hydroxyapatite is slowly resorbed.
The collagen gives COLLAPAT® II its strong haemostatic power and is completely resorbable in a few weeks. The collagen is extracted from bovine dermis.
The manufacturing procedure comprises stages recognized to inactivate viruses and non-conventional transmissible agents such as Prions. These treatments make it possible to ensure maximum microbiological safety for COLLAPAT® II, in particular in respect to the agent responsible for BSE.
COLLAPAT® II is osteoconductive.
It is generally completely colonised by the healthy orthotopic tissue thanks to intensive bone regeneration.
COLLAPAT® II exerts a haemostatic effect on the bone surfaces that it covers and on the muscles that are partially freed and replaced during surgery, stopping bleeding in a few minutes.
COLLAPAT® II is used to promote the repair of various types of bone lesions:
- After extracting cortico-spongoid bone fragments.
- After tumour resection.
- In revision cases.
- In surgical spondylodeses.
- In cases of pseudarthrosis.
- In certain fractures treated by osteosynthesis.
COLLAPAT® II is also used to induce bone substance replacement in maxillo facial surgery and odonto-stomatology.
- After removal of wisdom teeth or impacted cuspids,
- After removal of radicular or dental cysts,
- Periodontal pocket debridement,
- Filling for a sinus grafts
- Restoration of bone stock following avulsion, trauma or tumours prior to fitting of implants.
Method of administration:
COLLAPAT® II must be used in perfectly sterile operating conditions after adequate preparation of the site to be treated.
COLLAPAT® II can be cut, using surgical scissors, to the desired dimensions to facilitate its application. After being wet with tissue fluids, antibiotics or saline solution, COLLAPAT® II becomes soft and paste-like, making it easy to use to fill the cavity requiring treatment.
Draining is strongly recommended but the drains must not be in direct contact with COLLAPAT® II.
Rinsing of the implanted area is to be avoided.
COLLAPAT® II is not designed to be removed except in the case of post-surgical infection.
In the case of widespread and very deep bone lesions or segment defects of more than 1 to 2 cm, autologous bone shavings or PRP (Platelet Rich Plasma) should be combined with COLLAPAT® II.
Bone instabilities require supporting osteosynthesis.
