20090062825 | ADJUSTABLE IMPLANT AND METHOD OF USE - A system includes an adjustable implant configured for implantation internally within a subject, the adjustable implant having a permanent magnet configured for rotation about an axis of rotation, the permanent magnet operatively coupled to a drive transmission configured to alter a dimension of the adjustable implant. The system further includes an external adjustment device configured for placement on or adjacent to the skin of the subject comprising at least one magnet configured for rotation, the external adjustment device further comprising a motor configured to rotate the at least one magnet, whereby rotation of the at least one magnet of the external adjustment device effectuates rotational movement of the permanent magnet of the adjustable implant and alters the dimension of the adjustable implant. The system includes drive control circuitry configured to drive the motor of the external adjustment device to achieve a target dimension of the adjustable implant. | 03-05-2009 |
20090112207 | 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. | 04-30-2009 |
20090112262 | SKELETAL MANIPULATION SYSTEM - A system for manipulating a portion of the skeletal system in the body of a mammal includes an implant having a first portion and a second portion, the first portion configured for coupling to a first location of the skeletal system and the second portion configured for coupling to a second location of the skeletal system. The system includes an adjustment device configured to change at least one of the distance or force between the first location and the second location, the adjustment device having a magnetic element configured for rotation about an axis of rotation, the magnetic element being operatively coupled to a drive element configured to alter at least one of the distance or the force between the first location and the second location. The system also includes an external adjustment device configured to magnetically couple to the adjustment device from a location external to the mammal. | 04-30-2009 |
20090112263 | SKELETAL MANIPULATION SYSTEM - A system for manipulating a portion of the skeletal system of a mammal includes an implant having a first portion and a second portion, the first portion configured for mounting at a first location of the skeletal system and the second portion configured for mounting at a second location of the skeletal system. The system further includes an adjustment device disposed on the implant and configured to apply a biasing force to the skeletal system, the adjustment device including a magnetic element configured for cyclic movement, the magnetic element being operatively coupled to a drive element configured to alter at least one of the distance or the force between the first location and the second location. The system includes an implantable feedback device operatively coupled to the implant that is configured to produce a response that is indicative of a condition of the implant which can be identified non-invasively. | 04-30-2009 |
20110237861 | ADJUSTABLE IMPLANT AND METHOD OF USE - A system includes an adjustable implant configured for implantation internally within a subject, the adjustable implant comprising a first permanent magnet configured for rotation about a first axis, the first permanent magnet operatively coupled to a drive transmission configured to alter a dimension of the adjustable implant. The system further includes an external adjustment device configured for placement on or adjacent to the skin of the subject, the external adjustment device comprising a second permanent magnet configured for rotation about a second axis and a third permanent magnet configured for rotation about a third axis different from the second axis; and wherein cooperative rotation of the second permanent magnet about the second axis and rotation of the third permanent magnet about the third axis result in rotation of the first permanent magnet about the first axis. | 09-29-2011 |
20120157996 | 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. | 06-21-2012 |
20130035544 | ADJUSTABLE IMPLANT AND METHOD OF USE - A system includes an adjustable implant configured for implantation internally within a subject and includes a permanent magnet configured for rotation about an axis of rotation, the permanent magnet operatively coupled to a drive transmission configured to alter a dimension of the adjustable implant. The system includes an external adjustment device configured for placement on or adjacent to the skin of the subject having at least one magnet configured for rotation, the external adjustment device further comprising a motor configured to rotate the at least one magnet and an encoder. Rotation of the at least one magnet of the external adjustment device effectuates rotational movement of the permanent magnet of the adjustable implant and alters the dimension of the adjustable implant. Drive control circuitry is configured to receive an input signal from the encoder. | 02-07-2013 |
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 |
