Abstract
A system for midface distraction including a left side distraction mechanism and a right side distraction mechanism, each including: an implantable anchor configured to be coupled to a bone of the malar region, an implantable anchor configured to be coupled to a bone of the cranium, and a distraction rod coupling the anchors. The system also includes a maxillary bridge configured to couple the left side distraction mechanism with the right side distraction mechanism and wherein couplings between the maxillary bridge and the right and left distraction mechanisms are configured to be internal to a patient.
Claims17
A system for midface distraction, comprising:
- a left side distraction mechanism and a right side distraction mechanism, each comprising:
- a first implantable anchor configured to be coupled to a bone of the malar region (“the malar bone”);
- a second implantable anchor configured to be coupled to a bone of the cranium (“the cranial bone”);
- and
- a distraction rod that, once coupled to the first implantable anchor and the second implantable anchor, comprises a free end disposed on a first side of the second implantable anchor and a moveable engagement disposed on an opposite side of the second implantable anchor wherein the moveable engagement comprises a ball-and-socket joint coupling the distraction rod to the first implantable anchor;
- and
- a maxillary bridge configured to couple the left side distraction mechanism with the right side distraction mechanism, and wherein couplings between the maxillary bridge and the right and left distraction mechanisms are configured to be internal to a patient.

A system for midface distraction, comprising:
- a left side distraction mechanism and a right side distraction mechanism, each comprising:
- a first implantable anchor configured to be coupled to a bone of the malar region, the first implantable anchor comprising a pin;
- a second implantable anchor configured to be coupled to a bone of the cranium;
- a distraction rod comprising a socket sized to capture the pin, wherein:
- the distraction rod, once coupled to the first implantable anchor and the second implantable anchor, comprises a free end disposed on a first side of the second implantable anchor and a moveable engagement disposed on an opposite side of the second implantable anchor wherein the moveable engagement comprises a pin and socket joint coupling the distraction rod to the first implantable anchor;
- and
- a maxillary bridge configured to couple the left side distraction mechanism with the right side distraction mechanism, and wherein couplings between the maxillary bridge and the right and left distraction mechanisms are configured to be internal to a patient.
4 more elements
A system for midface distraction comprising:
- a left side distraction mechanism and a right side distraction mechanism, each comprising:
- a distraction rod comprising a first end, a second end, and a threaded portion disposed between the first end and the second end;
- a first implantable anchor;
- a second implantable anchor comprising a internally threaded housing;
- wherein once the distraction rod is coupled to the first implantable anchor and the second implantable anchor:
- the first end of the distraction rod moveably couples the distraction rod to the first implantable anchor;
- the threaded portion of the distraction rod threadably couples the distraction rod to the second implantable anchor;
- the second end comprises a free end disposed on an opposite side of the a second implantable anchor from the first end;
- and
- the distraction rod couples the first implantable anchor with the second implantable anchor;
- and
- a maxillary bridge configured to couple the left side distraction mechanism with the right side distraction mechanism, and wherein couplings between the maxillary bridge and the right and left distraction mechanisms are configured to be internal to a patient.
