    摘要： A magnetic induction hearing aid where the microphone, the amplifying electronics, the battery and a coil are contained in a single housing which is located deep in the ear canal. A magnet is attached to portions of the middle ear by means of a malleus clip or by implantation between the tympanic membrane and the malleus. The magnet is vibrated by interaction with the magnetic field produced by the coil. Two amplifier designs are disclosed for use with different levels of hearing loss. The magnet can be coated with hydroxyapatite for permanent attachment to the body. The magnet is coated with hydroxyapatite by an ion implantation process, a plasma spraying technique or a method of applying the hydroxyapatite while a precoating polymeric material has not fully solidified.

    摘要： A mold for fabricating a device for repairing torn tissue or muscle such as the meniscus of the knee is provided. The mold includes a mold cavity adapted to receive molten material. The mold cavity has an inlet channel, a first portion, a second portion, and a first channel extending between the first and second portions. The inlet channel communicates with the first and second portions and is spaced from the first channel such that the molten material must flow from the inlet channel through the first portion or second portion before communicating with the first channel. The first channel is dimensioned to receive a first component such that the flow of molten material from the first and/or second portions into the first channel is substantially prevented when the first component is received in the first channel.

    摘要： A suture anchor includes a rivet for insertion into a predrilled bore hole in bone, and a setting pin which extends through an axial aperture in the rivet. Preferably the setting pin has barbed legs which are radially expandable to frictionally engage the walls of the bore hole to secure the anchor therein. The setting pin includes a suture accommodating aperture, surface, and/or slot. In one embodiment, a snap-fitting detent and notch are engageable with each other to form an escapement mechanism to position the setting pin at discrete positions within the axial aperture of the rivet.

    摘要： A prosthetic ligament assembly includes a nonaugmented prosthetic ligament for permanently replacing a natural ligament spanning first and second body members, such as the femur and tibia, and a bone screw adapted for tensioning the prosthetic ligament during implantation. The prosthetic ligament includes a load bearing member intertwined into a plain braid from a plurality of biocompatible, high strength, ultra high molecular weight polyethylene yarns. Each yarn includes at least fifty fibers and has a tensile strength greater than or equal to about 100,000 psi. The load bearing member has a gage section and a loop at each end thereof for anchoring the load bearing member to the body members. The load bearing member is preloaded to remove slack therefrom. The load bearing member may be used alone or may be formed into a hollow braid having a core disposed within the hollow portion of the braid to permit radiographic visualization of the prosthetic ligament. A sheath may be friction fit or molded onto the exterior of the gage section. The assembly also includes one or two bone screws for complimentary engagement with the loops of the load bearing member. The bone screws have a tapered section extending beneath the head of the screw to the shank for tensioning the prosthetic ligament during implantation.

    摘要翻译： 假肢韧带组件包括用于永久地替换跨越第一和第二身体构件（例如股骨和胫骨）的天然韧带的修饰韧带，以及适于在植入期间张紧假体韧带的骨螺钉。 假体韧带包括从多个生物相容的高强度超高分子量聚乙烯纱线缠绕成平纹编织物的承载构件。 每个纱线包括至少五十根纤维，并且具有大于或等于约100,000psi的拉伸强度。 承载构件在其每个端部具有一定量部分和一个环，用于将承载构件锚固到主体构件上。 承载构件被预加载以从其中移除松弛。 承载构件可以单独使用或者可以形成为具有设置在编织物的中空部分内的芯的中空编织物，以允许假体韧带的放射线显影。 护套可以摩擦配合或模制到计量部分的外部。 组件还包括一个或两个骨螺钉，用于与承载构件的环互补接合。 骨螺钉具有在螺钉头部下方延伸到柄部的锥形部分，用于在植入期间张紧假体韧带。
