ABSTRACT:
An improved dialysis cannula includes an obliquely sharpened point formed by an oblique ground surface. The point includes a front portion which is disposed at an obtuse angle to the remainder of the ground surface, thereby providing a lancet-like front portion which facilitates proper insertion of the cannula into the blood vessel of a patient.
