Abstract: An apparatus is disclosed for attaching a surgical needle having a generally cylindrical end portion 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 die face with an inner die surface portion. The inner die surface portion includes at least one generally planar crimping surface having an arcuate recess formed therein which extends along at least a portion of the planar crimping surface.

Abstract: A hydrocarbon leak detector apparatus detects defectively sealed packages by monitoring for the presence of a volatile hydrocarbonaceous substance that leaks from defective packages. The apparatus includes one or more sealable chambers, a vacuum generator pump, a hydrocarbon detector and conduit means for delivering air from the chamber(s) to the hydrocarbon detector.

Abstract: The present invention relates to an apparatus for attaching surgical sutures to eyeless surgical needles. The apparatus includes a frame for positioning and maintaining the needle while the suture is being attached and a rotating die system which selectively impacts the needle to secure the suture thereto.

Abstract: A method and apparatus for tipping surgical sutures which includes winding the suture around a drum while continuously monitoring the suture diameter in x and y directions and adjusting the tension on the suture to control the suture diameter as it is being wound. The drum is then placed in an apparatus which passes selected portions of the suture through a mist of cyanoacrylate tipping agent generated by ultrasonic atomization. The tipping agent quickly cures and the tipped portion of the suture may be cut to create a tipped end for insertion into a surgical needle to form a needle suture device.

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.

Abstract: A pair of dies is disclosed for attaching a surgical needle having a generally cylindrical end portion 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 first needle. Each die has a pair of extensions spaced apart from each other and defines a generally circular crimping surface portion corresponding in dimension and configuration to the generally cylindrical outer surface portion of the needle.
