Abstract
The invention relates to a cannula with a fixation mechanism actuable to secure the cannula above and below the body wall in a single operation. The preferred embodiment involves spiral slit tubing in the form of a sleeve secured to the distal end of the cannula while mounted loosely over the cannula at the proximal end. A motion, such as twist and/or translation, is applied to the sleeve to make the spiral slit tubing expand to fixate the cannula.
