The smart canula ® is collapsed over a mandrel prior to insertion and re-expanded in situ: superior flow, much smaller access aperture, and less trauma result !
Access to the vascular system is a key issue for cardio-plumonary bypass, and other types of extra-corporeal circulation. Traditionally, cannulas are selected with an outer diameter somewhat smaller than the inner diameter of the vessel selected for access. This approach severely limits flow if there is a large difference between the cannula size and the target vessel size. smart canula ® principle based on “collapsed insertion and expansion in situ” overcomes such limitations.
