A device for introduction into a body in a straight configuration and assuming within the body a predefined curved configuration, includes an elongated element formed from a number of segments interconnected so as to form effective hinges therebetween. When the elongated element is confined to a straight state, the effective hinges transfer compressive forces from each segment to the next so that the elongated element can be pushed to advance it through a conduit. When the elongated element is not confined to a straight state, the effective hinges allow deflection of each segment relative to adjacent segments until abutment surfaces of the segments come into abutment, thereby defining a fully flexed state of the elongated element with a predefined curved configuration. The device can be produced with a wide range of two-dimensional and three-dimensional curved forms, and has both medical and non-medical applications.

An electrosurgical instrument including a jaw part made up of mutually movable instrument legs which have facing sides on which one or more electrode areas are arranged / formed in each case, the movement of the instrument legs relative to each other being able to be limited by at least one first spacer acting on proximal end portions of the instrument legs and at least one second spacer acting on distal end portions of the instrument legs. At least one of the spacers on at least one electrode is manufactured from an electrically conductive material and is connected to the electrode in electroconductive fashion. Furthermore, the spacer cooperates with a local spacer abutment surface which is made of a non-conductive material and arranged in electrically insulating manner on at least one opposing electrode.

A field installable fiber optic connector includes a housing, a spring element seat and a ferrule holder that is inserted from the rearward end of the housing. A spring element inserted into the front of the housing abuts the spring element seat. A spring element retainer attached to the ferrule holder abuts the forward portion of the spring element to compress the spring element and bias the ferrule holder forward. An optical fiber stub disposed between opposed splice members in an aligning groove terminates intermediate the ends of the splice members. An optical fiber is inserted between the splice members and guided by the groove into abutment with the end of the optical fiber stub. A cam disposed about the ferrule holder is movable to facilitate insertion of the optical fiber and to clamp the optical fiber and the optical fiber stub between the splice members.

A spinal interbody fusion cage has a body whose anterior / posterior profile may be varied through angular positioning of one or more articulating segments of the body without changing the superior / inferior height of the body. The present spinal interbody fusion cage has N segments or sections wherein at least one segment is articulated relative to another segment via a connection point, pivot or pivot structure such that the anterior / posterior profile is variable through angular positioning of one or more of the segments. The pivot structure may be configured so as to allow unidirectional movement between the connecting segments thereby allowing articulation in one plane or to allow omni-directional movement between the connecting segments thereby allowing articulation in multiple planes. The various forms of the present interbody fusion cage include superior and inferior sides or bone abutment surfaces that have serrations, teeth or similar functioning structures (teeth). The teeth extend between the anterior end and the posterior end. The teeth may take different shapes but are configured to allow insertion of the spinal interbody fusion cage in an anterior-first manner while preventing and / or inhibiting the spinal interbody fusion cage from backing out posteriorly.
