  • Introducer for radiofrequency needle
    Patent number: 9125684
    Abstract: An introducer for a radiofrequency needle includes a hollow tube. An introducer for a radiofrequency needle may also include a radiofrequency needle that extends through the hollow tube. The hollow tube includes a first portion that includes a longitudinal axis and a second portion that includes a longitudinal axis, that extends at an angle relative to the longitudinal axis of the first portion and has a distal tissue piercing tip segment and a bevel. The bevel has a heel segment in which the inner edge is rounded. The inner edge is rounded substantially continuously along the heel segment in an amount sufficient to prevent snagging of a radiofrequency needle on the inner edge as the radiofrequency needle is moved during placement.
