  • Patent number: 10195042
    Abstract: A shoulder implant device includes one or more fixation features including an acromial intrusion element and an inflatable humeral balloon portion that receives a fluid through the acromial intrusion element. The intrusion element comprises a valve that can receive multiple needle sticks to add or remove fluid to or from the inflatable humeral balloon. The device is implanted in a subacromial space such that the one or more fixation features at least secure the device to the acromion and the inflatable balloon portion rests against the proximal end of the corresponding humerus. Fluid in the balloon portion maintains separation of the acromion and the humerus to reduce or prevent impingement.

  • Patent number: 10188501
    Abstract: A bifurcated stem graft (10) comprises a body (100) and a side branch (200) that forms an acute angle with the body (100). The side branch (200) comprises a covering film (220) and a first bare stent (240) only disposed on the covering film (220). Part of the first bare stent (240) is positioned adjacent a boundary line (230) of the body (100) and the covering film (220) and is located in a vertex angle area (250) of the acute angle. Due to the fact that part of the first bare stem (240) is attached to the vertex angle area (250), after the stem (10) is released, the self-expanded part of the first bare stent (240) enables the vertex angle area (250) of the side branch (200) to be effectively supported, the covering film is not prone to shrinkage, and a leading wire can enter easily.

  • Patent number: 10123879
    Abstract: Provided is a system and method for providing a non-binding allograft subtalar joint implant for surgical implant into a person's foot proximate to the ankle. This system for repair includes at least one sterile non-binding allograft subtablar joint implant provided as a pre-formed allograft rod plug “ARP” having a diameter about equal to an average width of a canal between a person's talus and calcaneus bones, the ARP being resiliently compressible and flexible. When snuggly disposed between the person's talus and calcaneus bones, the ARP compresses during normal use of the person's foot and maintains the canal in an anatomically correct alignment and reduces a tendency for abnormal motion between the person's talus and calcaneus bones. An associated method of use is also provided.

  • Patent number: 10098739
    Abstract: Among other things, there are disclosed embodiments of a valve implant that in particular examples are implantable within a blood vessel, which include a first set of elongate members, a second set of elongate members, and a hood affixed to the first set of elongate members. The first set of elongate members is resiliently deformable, and their distal ends are flared radially outward. The distal ends of the second set of elongate members are distal to the ends of the first set of elongate members. The hood is affixed to the first set of elongate members, and seals against the interior wall of the blood vessel in an expanded configuration. When blood flows from the proximal to the distal side of the valve implant, it presses on the hood, compressing the first set of elongate members, breaking the seal.

  • Patent number: 10098747
    Abstract: Disclosed herein are knee replacement systems for replacing the articular surface of a distal femur. The systems include one or more unicompartmental components, namely patellofemoral, lateral condylar and medial condylar components. The components are configured such that when engaged to the femur the peripheries thereof do not cross specific locations and/or regions of the femur, namely the intercondylar notch and condylopatellar notch. The patellofemoral components described herein preferably have an extension portion extending posteriorly from a posterior periphery thereof towards an intercondylar notch of the femur without contacting the intercondylar notch of the femur when the patellofemoral component is engaged to the femur. The extension portion preferably extends posteriorly from a posterior periphery of the patellofemoral component towards the condylopatellar notch of the femur without contacting the notch.
