20130296859 | SKELETAL MANIPULATION METHOD - A method of treating scoliosis in a subject includes securing a scoliosis treatment device to first and second locations on the subject's skeletal system, the scoliosis treatment device including a first portion, a second portion moveably mounted relative to the first portion, and an adjustment device disposed on the device and configured to change a distraction force between the first location and the second location, the adjustment device including a rotationally mounted magnetic element configured to move the second portion relative to the first portion in response to rotation of the magnetic element. An external adjustment device is provided external to the subject and is able to adjust the distraction force between the first location and second location. | 11-07-2013 |
20140018804 | DYNAMIC TISSUE HOLDING DEVICE WITH LOW PROFILE SPRING - A dynamic tissue holding device is disclosed for dynamically holding two tissue portions in contact with one another. The device comprises a biasing spring having a relatively low profile, and a band adapted for extending about the tissue portions to be held together. The band has a first end for attachment to a first attachment portion on the biasing spring and a second end for attachment to a second attachment portion on the biasing spring. The band establishes a path of tension along its length and extending linearly between the two ends of the band. Advantageously, more than one-half of the biasing spring is disposed outside of the path of tension when the dynamic tissue holding device is in place and holding the two tissue portions together. | 01-16-2014 |
20140039495 | METHODS OF SECURING A FASTENER - Embodiments may include an attachable fastener, which may include a bondable material that may be secured to the end of an end effector. Vibration may be tuned to occur at a distal end of the fastener. Accordingly, the fastener may be used to generate heat at a distal point of contact. If the contact surface contains bondable material, that material may be softened. If the fastener includes bondable material at the point of contact, that material may also be softened by heat produced by vibration at the contact area. A hard implant or another polymeric material may function as the anvil. | 02-06-2014 |
20140128868 | APPARATUS AND METHODS FOR MAGNETIC ALTERATION OF ANATOMICAL FEATURES - Systems and methods are disclosed for manipulating an anatomical feature within the body of the patient. | 05-08-2014 |
20140350559 | ORTHOPEDIC IMPLANT AUGMENTS - Systems, methods, and devices are described for providing orthopedic implant augments having fastener locking mechanisms. The augments include a surface for mating with an implant component and a surface for interfacing with a patient's bone. The fastener locking mechanisms are aligned such that the augment may be locked in a variety of orientations while maintaining close contact with both an implant and a patient's bone. The alignment of the locking mechanisms provides variability and adjustability to the augment to address a variety of bone anatomies and requirements. | 11-27-2014 |
20150133934 | Implant - A method of manufacture of an at least partially bioresorbable implant, the method comprising the steps of: providing an at least partially bioresorbable precursor containing a polymeric material; and forming an implant by forging the precursor. An at least partially bioresorbable forged implant containing a polymeric material. | 05-14-2015 |
