  • Patent number: 8083664
    Abstract: Devices and methods for stabilizing tissue within a patient's body. Such a device is adapted to assume a reduced configuration and an operating configuration. The device assumes the reduced configuration for passage through a small opening to deliver a working end of the device to a site of the tissue to be stabilized. Such a device may include first and second contact members that are mounted for rotation, with each having a contact surface adapted to contact a surface of the tissue. When the device is in the operating configuration, a largest cross-sectional dimension of the contact members may be greater than a largest dimension of an opening through which the contact members were passed. However, when in the reduced configuration, largest cross-sectional dimension of the contact members is less than the largest dimension of the opening.

  • Patent number: 8015978
    Abstract: In general, the invention is directed to techniques for locating an implanted object using an external antenna. The implanted object may be, for example, an internal antenna that facilitates recharging of and/or communication with an implantable medical device. An external device coupled to the external antenna drives the antenna with a plurality of waveforms. Asymmetry in the loading profile of the external antenna when it is driven by the plurality of waveforms allows the external device or another device to determine the location of the implanted object relative to the external antenna. The external device or other device may provide information to a user based on the determined location of the implanted object relative to the external antenna, such as information to help a user position the external antenna with respect to an internal antenna in embodiments in which the implanted object is an internal antenna.

  • Patent number: 7972261
    Abstract: An anchor mechanism includes a sleeve to fit around a structure such as a radioactive source, a thermal ablation implant, a spacer, a strand or a radiopaque marker. The sleeve has a bore that extends an entire longitudinal length of the sleeve, and through which the structure fits, such that the structure can extend out from both longitudinal ends of the sleeve. One or more protrusion extends from an outer surface of the sleeve to engage surrounding patient tissue after implantation of the structure into a patient, to thereby reduce a tendency for the structure to migrate and rotate after implantation.

  • Patent number: 7971592
    Abstract: In the present invention, because no examples are known of binding of magnetic particle to mesenchymal cell or chondrocyte which might be used in regenerative medicine, whether or not a cell having the magnetic particle bound thereto is retained in local by external magnetism after administration and whether or not the cell can exhibit intrinsic activity is studied. According to the present invention, a magnetic cell comprising mesenchymal cell or cultured chondrocyte having magnetic particle bound to the surface thereof is provided, and when the cell is administered in vivo and an external magnetic field is applied, the cell can be retained for a long time at a disease site. Moreover, a drug delivery system can be constructed by causing the magnetic cells to contain a drug.
