연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

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 portio...

The device of claim 1, wherein a first bone includes the first bone portion and the second bone portion. 3. The device of claim 1, 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. 4. The device of claim 3, wherein said expansion shaft translates in said housing a first distance and the second bone portion grows a second distance. 5. The device of claim 1, wherein said bone replacement is configured to prevent an additional application of force on said connection system when said joint is in one of a flexion condition, an extension condition, and a plurality of positions between said flexion condition and said extension condition. 6. 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. 7. 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. 8. The device of claim 7, wherein said bearing component further includes a cannulated portion through which the connection system passes. 9. The device of claim 8, wherein said bearing component is a tibial resurfacing component. 10. 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. 11. 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. 12. The bone device of claim 11, wherein said cable includes a plurality of projections that meshingly engage said expansion shaft. 13.

The implant of claim 22, wherein said articulable joint includes a cannulated portion through which the connection system passes. 24. The implant of claim 23, wherein said cannulated portion is configured to prevent tension of said connection system by flexion and extension of said articulable joint. 25. 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. 26. 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. 27. The bone device of claim 26, wherein said expansion shaft is configured to releaseably connect to said intramedullary stem. 28.
