Abstract

A medical device that may include a main body and a plurality of hooks. The main body includes a length extending along an axis between first and second ends. The main body may be deformable such that the axis forms an arch shape corresponding to a shape of a mandibular jaw or a maxillary jaw. The main body may include a plurality of sections each having first and second edges defining a first width and a plurality of openings disposed between the first and second edges and extending through a thickness of the main body. The main body may include a plurality of recessed portions defining a second width disposed between adjacent ones of the sections. Each of the hooks may extend from a corresponding one of the sections.

First claim

What is claimed is:

1. A method for stabilizing a maxilla or a mandible of a patient, the method comprising:
obtaining or providing a first medical assembly, the first medical assembly comprising:
an elongated, contourable plate having a longitudinal axis, a plurality of sections extending parallel to the longitudinal axis, a plurality of recessed portions, each recessed portion of the plurality of recessed portions positioned between two of the plurality of sections along an axis parallel to the longitudinal axis, a plurality of apertures, wherein at least two apertures of the plurality of apertures is defined through each section of the plurality of sections, and a plurality of hooks extending from the plate, wherein a single hook of the plurality of hooks is positioned below each aperture of the plurality of apertures, and
a plurality of fasteners, each fastener of the plurality of fasteners including a head and a shaft, wherein the shaft includes a tapered distal end, a first threaded portion, and a second threaded portion between the first threaded portion and the head, wherein the second threaded portion has a greater diameter than the first threaded portion, and wherein the second threaded portion has a larger lead than the first threaded portion,
positioning the first medical assembly over the maxilla or the mandible; and
driving each of the plurality of fasteners through a respective aperture of the plurality of apertures and into the maxilla or the mandible to stabilize the maxilla or the mandible with the first medical assembly,
wherein driving the second threaded portion through the aperture causes the section defining the aperture to move away from the maxilla or the mandible, thereby creating a gap between the section of the plate and gingival tissue when the first medical assembly is in a fixed, implanted position.

2. The method of claim 1 , wherein the second threaded portion has at least twice the lead as the first threaded portion.

3. The method of claim 1 , wherein driving the plurality of fasteners through the plurality of apertures includes:
threadably driving the first threaded portion of a fastener of the plurality of fasteners through an aperture of the plurality of apertures, through gingival tissue and into the maxilla or the mandible; and
engaging the second threaded portion of the fastener with a chamfered periphery of the aperture.

4. The method of claim 1 , further comprising:
bending the elongated, contourable plate from a pre-deployment shape to a shape corresponding to the maxilla or the mandible.

5. The method of claim 1 , further comprising:
obtaining or providing a second medical assembly including an elongated, contourable plate and a plurality of hooks extending from the plate; and
positioning the second medical assembly over the mandible,
wherein positioning the first medical assembly includes positioning the first medical assembly over the maxilla.

6. The method of claim 5 , further comprising:
connecting at least one of the hooks of the first medical assembly to at least one of the hooks of the second medical assembly.

7. The method of claim 6 , wherein connecting at least one of the hooks of the first medical assembly to at least one of the hooks of the second medical assembly includes wrapping wire around the hooks.

8. The method of claim 5 , further comprising:
positioning the first medical assembly and the second medical assembly such that the plurality of hooks of the first medical assembly and the plurality of hooks of the second medical assembly are generally aligned with each other.

9. The method of claim 5 , further comprising:
fixing the second medical assembly to the mandible, wherein the second medical assembly further includes:
a plurality of fasteners, each fastener of the plurality of fasteners including a head and a shaft, wherein the shaft includes a tapered distal end, a first threaded portion, and a second threaded portion between the first threaded portion and the head, wherein the second threaded portion has a greater diameter than the first threaded portion, and wherein the second threaded portion has a larger lead than the first threaded portion, and
a plurality of apertures configured to receive the plurality of fasteners to fix the second medical assembly to the mandible;
wherein fixing the second medical assembly to the mandible includes driving the plurality of fasteners through the plurality of apertures and into the mandible to stabilize the mandible with the second medical assembly;
wherein driving the second threaded portion through the aperture causes the aperture to move away from the mandible, thereby creating a gap between the aperture and gingival tissue when the second medical assembly is in a fixed, implanted position.

10. The method of claim 1 , wherein each aperture of the plurality of apertures has a chamfered surface extending around a periphery thereof and driving the plurality of fasteners through the plurality of apertures comprises driving until the head engages the periphery.

11. A method for stabilizing a maxilla or a mandible of a patient, the method comprising:
obtaining or providing a first medical assembly comprising:
a contourable plate extending along a first longitudinal axis and including a plurality of sections separated by a recessed portion;
a plurality of openings positioned along a second longitudinal axis parallel to the first longitudinal axis, such that each opening extends through a section of the plurality of sections;
a plurality of hooks, wherein there is an equal number of the plurality of hooks and the plurality of openings such that one hook is positioned below each opening; and
a plurality of fasteners having a tapered distal tip, a first threaded portion positioned proximal to the tapered distal tip, a second threaded portion positioned proximal to the first threaded portion, and a head positioned proximal to the second threaded portion, the first threaded portion having threads with a smaller diameter than threads of the second threaded portion, and the second threaded portion having a larger lead than the first threaded portion;
bending at least a portion of the contourable plate from a pre-deployment shape into a deployment shape corresponding to a shape of the maxilla or the mandible;
inserting a fastener of the plurality of fasteners through an opening of the plurality of openings;
threadably driving the first threaded portion of the fastener through gingival tissue and into the maxilla or the mandible; and
engaging the second threaded portion of the fastener with a periphery of the opening defined by the section to move the section away from the gingival tissue.

12. The method of claim 11 , wherein obtaining or providing a first medical assembly comprises (i) selecting the contourable plate that corresponds to a size of the maxilla or the mandible, or (ii) trimming the contourable plate to correspond to the size of the maxilla or the mandible.

13. The method of claim 11 , further comprising:
threadably driving the second threaded portion of the fastener through the opening such that the section defining the opening moves away from the maxilla or the mandible, thereby creating a gap between the gingival tissue and a mounting tab defining the opening.

14. The method of claim 11 , further comprising:
obtaining or providing a second medical assembly comprising:
an elongated, contourable plate,
a plurality of apertures,
a plurality of hooks extending from the plate, and
a plurality of fasteners;
bending at least a portion of the plate of the second medical assembly from a predep
