The disclosure relates to an implantable woven graft for bridging a defect in a main vessel near one or more branch vessels. The graft includes a region of reduced density. Reduced density regions are alignable with at least one of the one or more branch vessels, and are suitable for in situ fenestration, for example by perforation. The disclosed examples are particularly suited for bridging abdominal aortic aneurysms.

An apparatus for inserting a spinal implant includes a first elongate member and a second elongate member operatively connected to each other. The first elongate member includes a first jaw member disposed at a distal portion thereof. The first jaw member defines a first longitudinal axis. The second elongate member includes a second jaw member disposed at a distal portion thereof. The second jaw member defines a second longitudinal axis. The first and second elongate members are adapted to move the first and second jaw members between a first position where the first and second longitudinal axes are oriented substantially parallel to each other and a second position where the first and second longitudinal axes are oriented at an acute angle with respect to each other. The apparatus further includes a locking mechanism adapted to fix a relative position of the first and second elongate members.

A dynamic cervical plate includes a first end section and a second end section. In embodiments, the dynamic cervical plate may include one or more middle sections positioned between the first and second end sections. Each section may be longitudinally repositionable. Each section may include a plurality of openings for receiving threaded fasteners such as a self-starting screw or a self-tapping screw. In addition, each section may include an orifice for releasably mating with a drill guide. Each of the end sections may include a notch at one end for aligning with the drill guide or fixation pins. In one embodiment, a pin is used to interconnect the sections. In other embodiments, support bars are used to limit flexure between sections. In embodiments, one or more locking elements and/or one or more support bars may operably interconnect each section.

A toy includes a base member and coupling member. In one embodiment, the base member has, for example, three attachment posts. The coupling member is configured to be removably coupled to any one of the attachment posts. The coupling member is also configured to be removably coupled among the three attachment posts. In one embodiment, the coupling member includes three projections that define a receiving portion. The receiving portion is configured to receive at least a portion of any one of the attachment posts. The projections of the coupling member are configured to be coupled among the three attachment posts. In another embodiment, the base member includes a prearranged play area that has a spherical portion, a cylindrical portion, and a wall portion. The coupling member is configured to be removably coupled to the spherical portion, the cylindrical portion, and the wall portion of the base member. In another embodiment, the coupling member includes an entertainment feature, such as, for example, a figure.

The present disclosure provides a cannulated bone screw system including a screw with a threaded portion, a non-threaded portion, and a first plurality of teeth spaced apart from a screw head; and a washer with an interior portion with a second plurality of teeth and an opening and an outer portion with a plurality of spikes. The first plurality of teeth are on an inferior convex surface; wherein the second plurality of teeth are on a superior concave surface; and wherein the first plurality of teeth and the second plurality of teeth are operable to mate to prevent the screw from backing out of the washer while allowing the cannulated bone screw system to conform/pivot in order to accommodate different bone morphologies.
