ABSTRACT:
An apparatus for percutaneous catheterization of a vascular or other body compartment employs a shape memory alloy cylindrical cannula which expands after introduction into the body compartment with sufficient radial force to dilate the vascular member. A cylindrical plastic sheath embracing the cannula facilitates introduction and insulates the vascular compartment from contact with the metal of the cannula.
