  • Patent number: 10252032
    Abstract: Anchors for securing a medical device relative to a body portal, wherein the anchors may accommodate most any implantation trajectory through the portal. Such anchors may further secure the device along any such trajectory without imparting undesirable biasing forces that may shift the device from its intended implanted location. In some embodiments, the anchor is configured as a burr hole anchor including a spherical member contained in a socket of the anchor such that orientation of the spherical member is permitted about three mutually perpendicular axes.

  • Patent number: 10195088
    Abstract: A nose compression device for treating a nosebleed of a person. The device includes a wire frame having a straight middle section and two end sections angled with respect to the middle section. The device also has a body attached to the wire frame, and two nasal sponges attached to the body for insertion into the person's nasal passages. The end sections are wider than the user's nose, and the device is slid upward on the user's face so that the nasal sponges enter the user's nasal passages. The end sections are then bent inward to a pinch position where they pinch the upper lateral side surfaces of the user's nose. The nasal sponges can be pre-treated with medication to further stop the nosebleed. Ice pack may also be provided that extends over the compression device. The combination of compression, medication, and cooling facilitate treatment of the nosebleed.
