Abstract
A surgical needle having an I-beam configuration is disclosed. The surgical needle comprises an elongated member having an I-beam cross section wherein two opposed flange members are connected by a web member. The elongated member has a piercing point extending from its distal end. A cylindrical mounting section extends from the proximal end of the needle for receiving an end of a suture. The needle has increased resistance to bending and buckling when compared to conventional needles and does not have an increase in resistance or drag.
