Patent

CA 2490027

A tissue growth apparatus (125) and method are provided for growing tissue by applying a tissue growth medium (110) to the tissue (124)and applying reduced, sub-atmospheric pressure at the growth medium (110) and the tissue (124) in a controlled manner for a selected time period. The application of reduced pressure at the growth medium (110) and tissue (124) promotes growth of the tissue within the tissue growth medium. The apparatus includes a tissue cover (118) sealed over a tissue site. The apparatus also includes a tissue growth medium (110) located beneath the tissue cover (118) and in contact with the tissue (124) to be grown. A vacuum pump (130) supplies suction within the tissue cover (118) over the tissue site to provide reduced pressure to the tissue (124) and the tissue growth medium (110).

L'invention porte sur un appareil et sur un procédé permettant de développer un tissu en appliquant sur ce dernier un support de croissance et une pression sous-atmosphérique réduite au niveau du support de croissance et du tissu, cela, de manière contrôlée, sur une durée sélectionnée. L'application d'une pression réduite au niveau du support de croissance et du tissu favorise la croissance du tissu dans le support de croissance. L'appareil comprend un élément de recouvrement scellé hermétiquement sur un site tissulaire, ainsi qu'un support de croissance du tissu placé sous l'élément de recouvrement du tissu et en contact avec le tissu. Une pompe à vide génère une aspiration dans l'élément de recouvrement se trouvant sur le site tissulaire de façon à réduire la pression sur le tissu et sur le support de croissance.
