  • Patent number: 8784482
    Abstract: Devices, systems, and methods employ an implant that is sized and configured to attach in, on, or near the annulus of a dysfunctional heart valve. In use, the implant extends either across the minor axis of the annulus, or across the major axis of the annulus, or both. The implant restores to the heart valve annulus and leaflets a more functional anatomic shape and tension. The more functional anatomic shape and tension are conducive to coaptation of the leaflets, which, in turn, reduces retrograde flow or regurgitation.

  • Patent number: 8353965
    Abstract: A technique to manufacture small joint orthopedic implants includes the steps of taking standard radiographs of a pathologic joint and the corresponding non-pathologic joint. In order to provide an accurate frame of reference, a specialized marker is placed in the radiographic field. By inspection of the radiographs and by comparison with the marker, the dimensions of the cortical bone and the cancellous bone can be quickly and accurately determined. These dimensions can be used to manufacture a suitable implant and installation tool. Typically, the implant will include a stem from which a post projects. A radially extending collar is located at the intersection between the stem and the post. A mating head is attached to the post. The head closely approximates the size and shape of the natural head being replaced. The stem will be non-round in cross-section to prevent rotation of the stem in the bone.

  • Patent number: 8337549
    Abstract: To prevent intimal hyperplasia within a dialysis graft, a flexible tube comprising the dialysis graft is coated interiorly with an anticarcinogen or mitosis-inhibiting agent for preventing cell division. The graft can also be irradiated by directing light into the lumen of the tube that has been grafted to the patient's blood vessel. The light source can be a light emitting diode (LED) or a chemical light source, i.e., a chemiluminescent substance for producing cool light energy at the site of the graft in sufficient amount to prevent undesired cell proliferation within the vessels, within the graft, or surrounding tissue where the invention is used without detectable damage to body tissue. Visible light can be used, e.g., visible blue or red light or the combination can be produced by an incandescent lamp or other suitable lamp, an LED, a laser or chemical light source with wavelengths predominantly between about 300 nm to about 800 nm.
