Abstract
The present invention relates to a non-invasive expandable implant utilizing energy from an epiphyseal growth plate of a human long bone to expand the implant. A bone replacement section includes a housing, an expansion shaft, a connection system, and an implant member. An anchoring member is secured to the second bone portion and spaced from the implant member. The expansion shaft is configured to translate a first distance between the housing and the first bone member. Growth of the bone causes an increase of a second distance between an implant portion and the anchoring member. The increase of the second distance causes the anchoring member to exert a force on a connection system causing an increase of the first distance, thus expanding the implant.
Claims28
A non-invasive expandable bone device adapted to be in a first bone portion of a patient that is capable of using growth of a second bone portion to elongate the first bone portion, the device comprising:
- a bone replacement configured to be secured to the first bone portion;
- an anchoring member configured to be secured to the second bone portion;
- and
- a connection system including a cable that connects said bone replacement to said anchoring member, wherein said connection system is configured to expand said bone replacement in response to a force exerted by said anchoring member due to the growth of the second bone portion,
- wherein said bone replacement includes an articulable joint that connects the first bone portion to the second bone portion.
A non-invasive expandable bone device adapted to be in a first bone portion of a patient that is capable of using growth of a second bone portion to elongate the first bone portion, the device comprising:
- a bone replacement configured to be secured to the first bone portion;
- an anchoring member configured to be secured to the second bone portion;
- and
- a connection system including a flexible connector that connects said bone replacement to said anchoring member, wherein said connection system is configured to expand said bone replacement in response to a force exerted by said anchoring member due to the growth of the second bone portion,
- wherein said bone replacement includes an expansion shaft that is configured to translate within a housing and is adapted to connect to the first bone portion,
- wherein said expansion shaft translates in said housing a first distance and the second bone portion grows a second distance, and
- wherein a first increase in said first distance is caused by a second increase in said second distance.
A non-invasive expandable bone device adapted to be in a first bone portion of a patient that is capable of using growth of a second bone portion to elongate the first bone portion, the device comprising:
- a bone replacement configured to be secured to the first bone portion;
- an anchoring member configured to be secured to the second bone portion;
- a connection system including a flexible connector that connects said bone replacement to said anchoring member, wherein said connection system is configured to expand said bone replacement in response to a force exerted by said anchoring member due to the growth of the second bone portion;
- and
- a bearing component that is configured to engage said bone replacement and adapted to secure to the second bone portion.
A non-invasive expandable bone device adapted to be in a first bone portion of a patient that is capable of using growth of a second bone portion to elongate the first bone portion, the device comprising:
- a bone replacement configured to be secured to the first bone portion;
- an anchoring member configured to be secured to the second bone portion;
- and
- a connection system configured to connect said bone replacement to said anchoring member,
- wherein said connection system is configured to expand said replacement section in response to the growth of the second bone portion, and
- wherein said connection system includes a cable that connects said bone replacement to said anchoring member and transmits a force from said anchoring member to said bone replacement to expand said bone replacement.
A non-invasive expandable bone device adapted to be in a first bone portion of a patient that is capable of using growth of a second bone portion to elongate the first bone portion, the device comprising:
- a bone replacement section having a housing, an expansion shaft, a connection system and an implant member;
- and
- an anchoring member secured to the second bone portion and spaced from said implant member,
- wherein said expansion shaft is configured to translate within said housing a first distance and is adapted to connect to the first bone portion, said first distance between said housing and the first bone member,
- wherein said implant member is configured to be secured to at least a portion of the second bone portion and includes a cannulated portion through which said connection system passes,
- wherein growth of the second bone portion causes an increase of a second distance between said implant portion and said anchoring member, said increase of said second distance causes said anchoring member to exert a force on said connection system causing an increase of said first distance,
- wherein said connection system includes a flexible connector secured to said anchoring member and connected to said expansion shaft,
- wherein movement of said anchoring member causes movement of said expansion shaft and
- wherein said bone replacement section further includes an articulable joint.
A non-invasive expandable bone device adapted to be in a first bone portion of a patient that is capable of using growth of a second bone portion to elongate the first bone portion, the device comprising:
- a bone replacement section having a cannulated articulable joint member connecting the first bone portion to the second bone portion,
- an anchoring member configured to be secured to the second bone portion;
- and
- a connection system including a flexible connector that connects said bone replacement to said anchoring member,
- wherein said connection system is configured to expand said bone replacement section in response to a force exerted by said anchoring member due to the growth of the second bone portion;
- and
- wherein said articulable cannulated joint is configured to prevent additional application of tension on said connection system by the said articulable cannulated joint.
A non-invasive expandable bone device adapted to be in a first bone portion of a patient that is capable of using growth of a second bone portion to elongate the first bone portion, the device comprising:
- a bone replacement section having a housing, an expansion shaft, a connection system and an implant member;
- an anchoring member capable of being secured to the second bone portion and spaced from said implant member;
- and
- an intramedullary stem capable of being secured to the first bone portion,
- wherein said expansion shaft is configured to translate within said housing a first distance and is adapted to connect to the first bone portion, said first distance is between said housing and the first bone member,
- wherein said implant member is configured to be secured to at least a portion of the second bone portion and includes a cannulated portion through which said connection system passes,
- wherein growth of the second bone portion causes an increase of a second distance between said implant member and said anchoring member, said increase of said second distance causes said anchoring member to exert a force on said connection system causing an increase of said first distance,
- wherein said connection system includes a cable secured to said anchoring member and connected to said expansion shaft, and
- wherein movement of said anchoring member causes movement of said expansion shaft.
