Abstract:
1. An intralumenal medical access assembly featuring dynamic variable degrees of flexibility controlled in real time during a medical procedure, comprising: (a) a cannula with at least one cannula notch set along its length; and (b) a stylet having a length greater than about 50 mm with at least one stylet notch set along said length; wherein said stylet is both longitudinally slideable within and radially rotatable within, said cannula at any position along a functional linear length of the cannula, and wherein at one or more points of longitudinal alignment along said cannula functional linear length, the stylet notch set is radially rotatable to a degree of radial alignment with at least one cannula notch set, said radial alignment causing a variable flexibility of the assembly at the point of alignment.
