ABSTRACT:
An apparatus is disclosed for attaching a surgical needle having a generally cylindrical end portin defining an elongated aperture having a generally circular cross-section and a suture having a generally elongated end portion of generally circular cross-section corresponding in dimension to the elongated aperture of the needle. The apparatus includes a pair of dies, each having a generally arcuate surface portion having irregularities including concave portions such that when the cylindrical end portion of the suture is positioned within the aperture of the needle and the dies are positioned about the generally cylindrical end portion of the needle with the surface portions facing the outer surface thereof, the application of inward force to the dies causes the dies to impact the needle and produces inward crimping of the needle so as to attach the needle to the suture. The concave portions define material relief zones to receive and collect deformed material from the needle so as to avoid distortion of the needle. According to the invention, the symmetry of the needle is maintained and the attachment is predictable and superior to those of the prior art. A method of forming such attachment is also disclosed.
