  • Patent number: 10251745
    Abstract: A connector for attaching a connective tissue to bone includes a sling for supporting and holding the connective tissue. A trap generally cooperates with the sling. The trap includes an anchor end and a sling end and a generally tubular section configured to decrease in diameter upon application of a longitudinal tensile force. The trap is dimensioned to fit within a tunnel through bone so that the connective tissue emerges from one end of the tunnel and so that an interference screw can be inserted into the tubular section at the anchor end of the trap at the other end of the tunnel whereby a pulling force exerted on the sling causes the generally tubular section of the trap to constrict more tightly about the interference screw to prevent slippage and to deter withdrawal of the trap from the tunnel.

  • Patent number: 10206781
    Abstract: The present invention relates to a polymer scaffold design and method for treating segmental long bone defects without amputation that permits permanent regrowth of bone in the area of the segmental defect, without external fixation or other problems inherent in current systems. The polymer scaffold is preferably made from a poly(ester urea) polymer and includes an outer shell, sized to fit over a segmental defect in a bone, and a collagen containing material. In some embodiments, the collagen containing material is placed in a polymer insert sized to fit within the segmental bone defect and within said outer shell. In some embodiments, the outer shell may contain struts running longitudinal struts along the inside surface of the outer shell. In some of these embodiments, the insert will have a corresponding set of grooves sized to receive the struts.

  • Patent number: 10206780
    Abstract: The present invention implements a set of grooves/ridges created on Ti at the circumferential direction to increase surface area of implant in contact with bone. These grooves/ridges protect nanofiber matrix (NFM) made with Polycaprolactone (PCL) electrospun nanofiber (ENF) and collagen at the groove from physiological loading. Controlled fabrication of a ridge made with titanium nitride (TiN) around the circumference of Ti is provided using a plasma nitride deposition technique. PCL ENF may be deposited along the sub-micrometer grooves using the electrospin setup disclosed. The method provides for fabrication of microgroove on Ti using machining or TiN deposition and filling the microgrooves with the NFM. This method has proven through experimentation to be successful in increasing in vivo mechanical stability and promoting osseointegration on Ti implants. The immobilization of MgO NP and FN with the PCL-CG NFM on microgrooved Ti as provided in the invention optimizes biological performances of Ti.
