Method for perfusing a biocompatible material graft with a liquid and perfusion kit

Abstract

A method for perfusing a biocompatible material graft with a perfusion liquid includes the steps of : introducing the graft (100) in a perfusion chamber (2), arranging a transfer chamber (3) partly filled with the perfusion liquid (101), coupling in a tight manner the perfusion chamber (2) and the transfer chamber (3) for establishing a fluid communication between them, lowering the pressure in the transfer chamber (3) for transferring therein part of the air existing in the perfusion chamber (2), increasing the pressure within the transfer chamber (3) for injecting in the perfusion chamber (2) the perfusion liquid (101) existing in the transfer chamber (3). A perfusion kit includes a perfusion chamber (2) apt to contain a graft (100) to be perfused with a liquid (101) and a transfer chamber (3) apt to contain a liquid (101) to be perfused, the perfusion chamber (2) being connectable in a tight manner with the transfer chamber (3) for allowing a fluid exchange between the two chambers (2, 3) and inhibiting a fluid exchange between the two chambers (2, 3) and the external environment.

Description

technical field [0001] The present invention relates to a method for perfusing a biocompatible material implant using a liquid and a perfusion tool. Background technique [0002] In the context of the present invention, "biocompatible material implant" means a prosthetic element made of natural or synthetic material suitable for implantation into a living body to compensate for bony lacuna, osteochondral and / or cartilage tissue. [0003] In the field of orthopedic surgery, surgeons are often confronted with patients with varying degrees of elongated bone, osteochondral or cartilage lacunas. Such dimples may arise from a variety of causes, such as incomplete bone reunion following a fracture, delayed consolidation, malignancy, infectious influences, comminuted or distal fractures, neonatal deformities, trauma-induced structural changes, or other conditions. [0004] To cope with the lack of bone volume, various solutions have been proposed, in particular different natural, s...

AI Technical Summary

Problems solved by technology

Thus, due to the need to fill the perfusion lumen regardless of the graft size, in some cases (particularly when the graft has a reduced size), there is a need for perfusate (which is usually the amount withdrawn directly from the patient) Limited waste of valuable biological fluids)

[0014] In addition, in the perfusion method of the prior art, a non-negligible amount of air is dissolved in the perfusate during the process of filling the perfusion cavity
