摘要:
A bone fixation system including a plate and a set of fixation locking screw. The plate defines a set of locking screw holes each having an internal thread. Each respective locking screw has a head with an external structure that is adapted to self-tap into the internal thread of a given locking screw hole to secure the respective first-type fixation locking screw at an surgeon directed angle relative to the plate. This angle is defined during forcible insertion and rotation of the respective locking screw into the given screw hole. The system may also include unidirectional locking screws.

A fracture fixation device includes a plate portion and an intramedullary nail portion which is offset relative to the plate portion by a neck portion. The plate portion includes longitudinally displaced peg holes which orient pegs along an imaginary surface parallel to subchondral bone of an articular surface. The upper surface of the plate portion includes a dimple to reference a jig. The nail portion includes threaded screw holes oriented normal to an endosteal surface, and a smaller K-wire alignment hole parallel to the screw holes. The jig has a first portion which references with the dimple and a second portion in alignment over the screw holes of the nail portion. The back of the first portion of the jig is curved upward to facilitate maneuvering of the jig. The first and second portions of the jig includes K-wire guide holes which direct K-wires relative to holes in the device.

A guide catheter shaft is formed from an inner tube structure and a multilayer sheath around the inner tube structure. The multilayer sheath includes an intermediate sheath and a shrink tube layer. The intermediate sheath is disposed around the inner tube and realized from a melt-processible first polyether-block amide material. The shrink tube layer is disposed around the intermediate sheath and realized from a different second polyether-block amide (e.g. a cross-linked polyether-block amide material) having a shrink temperature range greater than a melt temperature range of the first polyether-block amide material. The resulting structure is heated at a temperature within the shrink temperature range such that the outer shrink tube layer shrinks and the intermediate layer melts to thereby bond the multilayer sheath to the inner tube.

A folding photo case includes a pair of exterior case members coupled to each other by a first hinge and a pair of interior frame members coupled to respective exterior case members by respective second and third hinges. The first, second and third hinges are preferably torsion bar hinges with the first hinge biasing the exterior case members to an open position and the second and third springs biasing the interior frame members toward interior surfaces of the exterior case members. One or both of the exterior case members are preferably provided with a latch structure which allows the folding case to be latched in a closed position. The dimensions of the folding case are preferably such that the case can be carried in a pocket or purse when it is folded into the closed position.

Time multiplexed processing of multiple SONET signals uses the same shared circuitry for framing, descrambling, maintenance signal processing, control byte processing and extraction, pointer tracking, retiming, and alarm indication. The signals are deserialized and multiplexed onto a byte-wide bus from which they are processed in a shared pipeline. Additional pipelines allow scaling up to higher capacity SONET signals. Each pipeline is provided with means for communicating with the other pipelines so that information derived from the processing of one stream can be shared with the processing of other streams when necessary. According to the presently preferred embodiment, bytes pass through the pipeline in five clock cycles.

A fracture fixation system includes a plate having a first suture anchor location having an opening at the upper surface of the plate, an opening at the proximal end of the plate, and an opening at the anterior side of the plate and defines first and second suture pathways which cross within the plate. The first and second suture pathways include a common opening. A second suture anchor location on the plate has an opening at the upper surface of the plate, an opening at the proximal end of the plate, and an opening at the posterior side of the plate which defines third and fourth suture pathways which cross within the plate. The third and fourth suture pathways also share a common opening. Thus, each suture anchor location is capable of providing a hold for suture from multiple approaches to secure tuberosities relative to the plate.

An intraocular lens (IOL) system includes an optic, a pair of haptics located on sides of the optic, and hinge portions at each of the optic haptic junctions. The hinge portions have stressed and non-stressed configurations. One or more restraining elements are provided to maintain the stressed state configuration of the hinge portion during implantation and during a post-operative period during which the capsular bag of the eye heals about the lens. The restraining elements are thereafter removable, preferably via a non-surgically invasive manner, e.g., via dissolution or laser light. Removal of the restraining elements allows anteriorization of the optic as the lens assumes a non-stressed configuration during accommodation. The ciliary body and lens may then interact in a manner substantially similar to the physiological interaction between the ciliary body and a healthy natural crystalline lens.

A system includes a drill guide and a gauge wire. The drill guide has two arms rotatable relative to each other about a hinge, with each arm including a split portion of a guide. When the arms are in a closed configuration, the split portions come together to form a tubular guide. Because the arms can be opened and closed about the hinge, the guide can be split and removed from over a drill bit or pin without first removing the drill bit from the bone or the drill from the drill bit or pin. Each arm also includes a semicircular form which when the arms are closed defines a gauge wire hole parallel to the guide which is sized to receive a gauge wire. The gauge wire includes depth indicia along its length which is used to indicate the length of a fixation device for use in a procedure.

An ossicular prosthesis delivery system having an ossicular prosthesis including an enlarged head and a shaft axially, moveably mounted to the head to adjust shaft length. An elongate main body having an operating portion, including a cylindrical through bore, connected to an adjusting portion, including a generally semi-cylindrical upwardly opening channel coaxial with the bore. An end wall at a distal end of the adjusting portion includes a through passage coaxial with the channel and an upwardly opening cavity. An elongate cylindrical plunger has a claw at one end. The plunger is received in the bore with the claw in the channel and an opposite end extending outwardly of the operating portion. The ossicular prosthesis' shaft is positioned in the channel with the head received in the cavity and the plunger is rotatable in the bore to capture the shaft and is reciprocally moveable in the bore to adjust shaft length of the ossicular prosthesis.

A cosmetic implant comprises a filament made from a biocompatible elastomer. The elastomeric filament can be injected or pulled under one or more wrinkles. Once implanted under the wrinkle(s), the filament lifts and supports the tissue above it. Such lifting lessens (and possibly removes altogether) the appearance of the wrinkle(s). The biocompatible elastomeric filament is preferably made from a polyolefinic copolymer material having a triblock polymer backbone comprising polystyrene-polyisobutylene-polystyrene, which is herein referred to as “SIBS”; or alternatively can be made from silicon rubber, expanded polytetrafluorethelyene (ePTFE), polyurethane, polyolefin, copolymers of nylon, copolymers of polyester, or elastin.
