Abstract

A method of attaching a magnetic element to a needle assembly. The needle assembly can include a cannula extending along a longitudinal axis. The method can include placing the magnetic element in a magnetic field such that a magnetic axis of the magnetic element substantially aligns with the magnetic field. The method can further include securing the magnetic element to a portion of the needle assembly while the magnetic element is substantially aligned with the magnetic field such that the magnetic axis of the magnetic element is secured in a desired predetermined orientation.
