Patent ID: 8556896

Claim:
A surgical system comprising: a guide wire having an enlarged tip; a surgical device with an elongated body, the elongated body comprising: an internal wall; a proximal end; a distal end, said elongated body defining a cannula spanning said proximal end and said distal end; and an enlarged distal relief portion at the distal end defined by the internal wall, the enlarged distal relief portion being concave with respect to a longitudinal axis of the cannula, and the enlarged distal relief portion defining an enlarged distal opening providing a distal access to said cannula; said enlarged distal relief portion having a maximum radial extent in a cross-section perpendicular to a longitudinal axis that is larger than said maximum radial extent in a cross-section perpendicular to the longitudinal axis of a corresponding proximate portion of said cannula; and said internal wall defining a continuous transition between said enlarged distal opening and said cannula, wherein a thickness of a wall of said enlarged distal relief portion increases from a distal end of said enlarged distal relief portion to a proximal end of said enlarged distal relief portion, whereby said enlarged distal relief portion is adapted to slidingly receive said enlarged tip of said guide wire.
