摘要： An interbody fusion device in one embodiment includes a tapered body defining a hollow interior or chamber for receiving bone graft or bone substitute material. The body defines exterior threads which are interrupted over portions of the outer surface of the device. The fusion device includes truncated side walls so that on end view the body takes on a cylindrical form. In another embodiment, the tapered body is solid and formed of a porous biocompatible material having sufficient structural integrity to maintain the intradiscal space and normal curvature. The material is preferably a porous tantalum composite having fully interconnected pores to facilitate complete bone tissue ingrowth into the implant. In further embodiments, the fusion devices are provided with osteogenic material to facilitate bone ingrowth. A cap is also provided to block the opening of hollow fusion devices. The cap includes an occlusion body and an elongated anchor. In some embodiments the anchor includes a lip which is engageable to openings in the body wall. Tools are also provided for manipulating caps for interbody fusion devices. In one embodiment the tool includes a pair of prongs each having facing engagement surfaces for engaging the fusion device, and a shaft slidably disposed between the prongs. The shaft has a first end defining a cap-engaging tip for engaging a tool hole in the cap. In one embodiment the cap engaging tip defines threads. In another embodiment the prongs include a pair of releasing members on each of the facing engagement surfaces. The releasing members have a height and a width for being insertable into apertures in a body wall in the fusion device to disengage the elongate anchors from the apertures.

摘要： A stack, having improved efficiency, for venting exhaust gases from a combustion chamber of a solid fuel burning apparatus, such as a boiler, to a flue. The stack, which can be retrofitted to certain wood burning furnaces or boilers includes an elongated tubular member having a first end, a second end and at least one inlet proximate the first end. The second end of the elongated tubular member defines an outlet which is adapted to register with a flue so as to vent combustion, or exhaust, gases from the combustion chamber to the atmosphere. Further, the stack includes at least one conduit member which is in fluid communication with the first tubular member. The conduit member includes an open end adapted to be in fluid communication with the combustion chamber and an oppositely disposed closed end which is proximate the inlet of the elongated tubular member and is in fluid communication with the inlet of the elongated member. The conduit member(s), defines a channel for communicating exhaust gases from the open end of the conduit member to the inlet of the elongated member creating a tortuous airflow path for combustion gases from the combustion chamber to the chimney via the open end of the conduit member through the outlet of the elongated tubular member to the flue.

摘要： Open chambered spacers, implanting tools and methods are provided. The spacers 500′ include a body 505′ having a wall 506′ which defines a chamber 530′ and an opening 531′ in communication with the chamber 530′. In one embodiment the wall 506′ includes a pair of arms 520′, 521′ facing one another and forming a mouth 525′ to the chamber 530′. Preferably, one of the arms 520′ is truncated relative to the other, forming a channel 526. In one aspect the body 505′ does a bone dowel comprise an off-center plug from the diathesis of a long bone. The tools 800 include spacer engaging means for engaging a spacer and occlusion means for blocking an opening defined in the spacer. In some embodiments, the occlusion means 820 includes a plate 821 extendable from the housing 805. In one specific embodiment the plate 821 defines a groove 822 which is disposed around a fastener 830 attached to the housing 805 so that the plate 821 is sliceable relative to the housing 805.
摘要翻译： 提供开放式隔板，植入工具和方法。 间隔件500'包括主体505'，其具有限定室530'的壁506'和与室530'连通的开口531'。 在一个实施例中，壁506'包括彼此面对的一对臂520'和521'，并且形成到腔室530'的口525'。 优选地，臂520'中的一个相对于另一个被截去，形成通道526.在一个方面，主体505'执行骨定位销，其包括来自长骨的素质的偏心塞。 工具800包括用于接合间隔件的间隔件接合装置和用于阻挡限定在间隔件中的开口的闭塞装置。 在一些实施例中，闭塞装置820包括可从壳体805延伸的板821.在一个具体实施例中，板821限定凹槽822，凹槽822围绕附接到壳体805的紧固件830设置，使得板821可相对于 外壳805。
