  • Patent number: 9163331
    Abstract: The invention is directed to compositions and methods for preparing electrospun matrices comprising at least one natural biological material component and at least one synthetic polymer material. The natural component makes the matrices highly biocompatible while the molecular weight polymer component can impart additional strength mechanical strength to the scaffold and/or improve ease of manufacture by increasing viscosity and spinning characteristics of the solution during electrospining.

  • Patent number: 7531503
    Abstract: The invention is directed to methods and compositions for preparing matrices for controlled delivery of at least one therapeutic or biological agent to a target site in a subject. This is accomplished using nanoparticles coupled to the therapeutic or biological agent that are incorporated within the matrix or reacted on the surface of the matrix.

  • Publication number: 20050075562
    Abstract: A device and method for targeting objects and specifically for locating intramedullary screw openings is described. The device and method include a target magnet and a sensor comprising an elliptical array of magnetoresistive elements, designed to give information on the three-dimensional orientation of the magnet. The sensor array is designed such that each magnetoresistive element is a member of an opposing pair and relays information on their alignment with the target magnet. The array is connected to a display such that the position of the sensor in relation to the target magnet is easily discerned. The invention is lightweight and portable, capable of operating on batteries and can be used in primitive situations where a stable supply of electricity is not available.
