Abstract: A fiber optic connector with a hub extension positioned on the hub of the connector. Prior to assembly of the connector with the rear boot, the hub and ferrule assembly can be pushed backward within the front and rear housings to clear an anti-rotation portion of the front housing and turned for tuning. After complete assembly of the rear boot, the hub extension bottoms out against the boot prior to the hub and ferrule assembly disengaging the anti-rotation portion of the front housing, thereby maintaining the tuned position.

Abstract: A system can form a pilot hole to secure a securable element, such as an acetabular cup. A saddle can removably attach to the securable element. The saddle can confine a translator and allow the translator to move along a translator axis between a first translator position and a second translator position. A punch element can be movably coupled to the saddle and the translator such that when the saddle is removably attached to the securable element, moving the translator from the first translator position toward the second translator position can advance a tip of the punch element from the saddle through the securable element along a punch axis that is angled with respect to the translator axis. An impaction stem can be coupled to the translator by a joint, such as a ball-and-socket joint, and can impart motion to the translator.

Abstract: To install a connectorized cable assembly, a cable terminated at a connector core is pushed through a duct. The connector core has a maximum outer diameter of no more than 5 mm to facilitate passage of the connector core through the duct. A plug body is mounted over the connector core after the connector core exits the duct. No intermediate assembly steps are performed on the connector core between being pushed through the duct and being inserted into the plug body.

One or more arcuate elements can extend from first end portions in the apex region towards second end portions proximate the base. At least a portion of the one or more arcuate elements can be located in the one or more arcuate channels to extend outward beyond the outer surface.

Abstract: A fiber optic connector with a hub extension positioned on the hub of the connector. Prior to assembly of the connector with the rear boot, the hub and ferrule assembly can be pushed backward within the front and rear housings to clear an anti-rotation portion of the front housing and turned for tuning. After complete assembly of the rear boot, the hub extension bottoms out against the boot prior to the hub and ferrule assembly disengaging the anti-rotation portion of the front housing, thereby maintaining the tuned position.

Abstract: Aspects and techniques of the present disclosure relate to fiber optic connectors with features that help eliminate the potential of a capillary effect or epoxy wicking. The fiber optic connector may include an epoxy tube with segments that define a pocket in an area that helps to prevent capillary action between components that are otherwise closely positioned.

Abstract: The present disclosure relates to a fiber optic connector designed to improve the insertion of an optical fiber within the fiber optic connector. The fiber optic connector may include a lead-in tube that makes the insertion of an optical fiber easier. That is, the lead-in tube may be molded over a ferrule hub to fully encapsulate a rear end thereof such that the optical fiber does not snag or hang up during insertion.

Abstract: The present disclosure relates to an epoxy tube for an optical fiber connector. The tube can be mounted to a ferrule hub by a snap fit connection. The connection between the tube and the ferrule hub allows for float of the epoxy tube where the epoxy tube is not rigidly attached to the hub. The epoxy tube can be configured to move about an arc of rotational circular movement while remaining linear such that the epoxy tube does not bend or transfer forces to the hub.

Abstract: The present disclosure provides a system and method for connecting an optical fiber to a ferrule. The system and method facilitate the process of epoxying the optical fiber in a manner that avoid inadvertently adhering the fiber to the side of a connector housing, which can result in breakage of the optical fiber when in the field. The system and method provide a mechanism for easily epoxying the optical fiber to the ferrule while still allowing for sonic radial movement of the optical fiber within the connector housing, which is desirable. The system and method incorporate an end cap that centers the optical fiber in the connector housing during the connection process and also acts as a strain relief when in the field.

The adjustable reamer heads and methods can include changing a cutting characteristic such as the size of an adjustable reamer head. In an illustrative example of an adjustable reamer head, the reamer head can include a housing, an actuator and a plurality of cutting elements. The plurality of cutting elements can be retained by the housing and can be operably coupled to the actuator. The plurality of cutting elements can include a first size cutting element and a second size cutting element. When the actuator is actuated, the first size cutting element and the second size cutting element can move relative to one another to change from a first cutting size to a second cutting size.

Abstract: Illustrative methods of manufacturing flexible drive shaft assemblies for preparing bone can include steps such as providing, receiving or manufacturing a mold. Injecting a first polymeric material into the mold to form a coupling member, the coupling member adapted for attachment to a torque-providing driving tool. Injecting a second polymeric material into the mold to form a work member, the work member adapted to interface with the bone to prepare the bone. The method can further include injecting a third polymeric material into the mold in an overmolding process to form a flexible shaft extending from the coupling member to the work member. The assemblies resulting from such methods can include a flexible shaft that is adapted to transmit a majority of a torque received from a torque-providing driving tool through the flexible shaft. In some examples, the flexible shaft can include a solid polymeric shaft.
