Patent ID: 7967799

Claim:
A tip for a liquefaction handpiece, comprising: an inner tube coaxially mounted within an outer tube so as to form an annular gap between the inner tube and the outer tube, the inner tube having at least one bypass hole in a sidewall of the inner tube; wherein the inner tube has an irrigation bore and a non-beveled distal tip, comprising a distal tip opening, and a spacer formed on the distal tip and extending past the distal tip opening to provide a spacing between the distal tip opening and tissue such that pulses exiting the distal tip opening travel the spacing before contacting the tissue, the spacer including an enlarged, curved tip; wherein the inner tube is configured to direct pulses of fluid out of the distal tip opening; wherein the bypass hole is configured to vent excessive pressure from the irrigation bore to the annular gap when the distal tip opening becomes at least partially obstructed; and wherein the distal tip opening forms a plane that is perpendicular to a centerline of the inner tube and wherein the spacer extends outward from the plane of the distal tip opening.
