Abstract
The invention relates to a cannula with a fixation mechanism actuable to secure the cannula above and below the body wall with minimal amount of manipulation and damage to the body wall. The preferred embodiment involves arms attached to springs secured to the body of the cannula over which a sleeve is slidingly mounted to restrain and release the springs. When the spring is released, it causes the arms to press against the inner body wall to fixate the cannula. A stop mounted on the sleeve can be positioned to apply a compressive force on the outer body wall, further securing the cannula.
