A mask system for use between a patient and a device to deliver a breathable gas to the patient includes a mouth cushion, a pair of nasal prongs, an elbow, and a headgear assembly. The mouth cushion is structured to sealingly engage around an exterior of a patient's mouth in use, and the pair of nasal prongs are structured to sealingly communicate with nasal passages of a patient's nose in use. The elbow delivers breathable gas to the patient. The headgear assembly maintains the mouth cushion and the nasal prongs in a desired position on the patient's face. The headgear assembly provides a substantially round crown strap that cups the parietal bone and occipital bone of the patient's head in use.

Methods and systems for occipital-cervical spinal fixation. A plate configured for attachment to the occipital bone has two arms extending out from either side, which turn downwards parallel to one another. A first bend is disposed in the arms, such that the arms extend down from the occipital bone behind the spinous process of the C1 and C2 vertebrae, upon installation. A second bend in the arms allows attachment to the C2 vertebra. The system may be dimensioned for pediatric installation. A bone graft material may be held in place between the cervical vertebrae and the skull by installing a cable to the installed system to retain the bone graft material in place. Methods and kits for occipital-cervical spinal fixation are also disclosed.

An artificial interbody spinal implant adapted for placement across an intervertebral space formed across the height of a disc space between two adjacent vertebral bodies is disclosed. The implant has an asymmetrical leading end adapted to sit upon the more peripheral areas, such as the apophyseal rim and the apophyseal rim area, of the vertebral end plate region of the vertebral bodies without protruding therefrom. The asymmetrical leading end allows for the safe use of an implant of maximum length for the implantation space into which it is installed. The implant can also include an asymmetric trailing end adapted to sit upon the more peripheral areas of the vertebral end plate region of the vertebral bodies.

An occipitocervical fixation system includes a plate for securing to the occiput and at least one pre-bent rod.

The clamping assembly is selectively pivotable and lockable in place to fix the position of the rod.

A harness assembly for a nasal mask for communicating breathable gas to a patient's airways, for example, in the administering of CPAP or like breathable gas delivery treatments, includes a cap portion adapted to engage, in use, the occipital region of the skull. The cap portion includes a connector at each end. The harness assembly also includes a pair of upper and lower straps, each of the straps extending between one of the cap connectors and the nasal mask. The harness assembly grips the head in a region substantially fixed relative to the face and, as such, tension of the straps is not substantially affected by head movement.

A spinal fixation plate that is adapted to be implanted in a variety of positions in the occiput is provided. In general, the plate has a substantially planar configuration and it includes a mid-line or central portion having several thru-bores formed therein, and first and second opposed branch portions that extend from the central portion and that also include at least one thru-bore formed therein. The configuration of the branch portions relative to the central portion, as well as the position of the mid-line thru-bores formed in the central portion in relation to the thru-bore(s) formed in each branch portion, allow the spinal fixation plate to be implanted in a variety of positions in the occiput, thus allowing the optimal implant site to be selected.

An occipital plate for use in an occipito-cervico-thoracic (OCT) construct is mounted to a patient's occipital bone. The occipital plate includes an elongate central section aligned with a midline of the base and a pair of angled sections that project away from the central section and include attachment assemblies for securing a rod to the occipital plate. The attachment assemblies have multi-adjustability features. At least a portion of the attachment assemblies is rotatable with respect to the base so that the rods may be coupled to the occipital plate at a variety of angles with respect to the midline. The angular adjustability may accommodate any misalignments in the rods. Additionally, the position of the attachment assemblies relative to the midline of the occipital plate is adjustable to thereby provide for medial-lateral adjustability when attaching the rods to the occipital plate as part of the OCT construct.

An interbody spinal implant is formed of cortical bone adapted for placement across an intervertebral space formed across the height of a disc space between two adjacent vertebral bodies. An asymmetrical leading end on the implant is adapted to sit upon the peripheral areas, such as the apophyseal rim and the apophyseal rim area, of the vertebral end plate region of the vertebral bodies without protruding therefrom. The asymmetrical leading end allows for the safe use of an implant of maximum length for the implantation space into which it is installed. The implant can also include an asymmetric trailing end adapted to sit upon the more peripheral areas of the vertebral end plate region of the vertebral bodies.

A cervical brace and therapy device for use to rehabilitate an injured neck of a person is described having a base support structure shaped to fit about the neck and rest on the shoulders of the person; a support ring assembly attachable to the base support structure in a horizontal position below the mandible of the person, the support ring assembly having an anterior section and a posterior section; a rotational member attached to the support ring assembly in a manner to rotate about the support ring assembly; and an occipital-mandible support member shaped to accommodate the mandible and the occipital portions of the head of the person, the occipital-mandible support member being attachable to the rotational member in a manner to permit the occipital-mandible support member a predetermined range of rotation.

A method of treating pain in a subject includes the step of positioning a tip of one or more leads subcutaneously in the occipital region of a subject's scalp, where the leads are configured to conduct an electrical signal along an occipital nerve into the brain. The leads are energized to conduct the electrical signal along the occipital nerve and the electrical signal is adjusted to a level effective to decrease the subject's pain over time and so that the subject cannot feel the lead being energized.

A method of treating chronic pain in a subject by positioning a lead containing electrodes subcutaneously in the occipital region of a subject's skull at the height of an imaginary line connecting the tops of the ears; and energizing the lead with an electrical signal effective to suppress pain, and below the level where the subject can feel the lead being energized. Typically the procedure involves a trial phase and a permanent implant phase. The procedure is known as occipital neuromodulation.

An occipital plate for use in an occipito-cervico-thoracic (OCT) construct is mounted to a patient's occipital bone. The occipital plate includes an elongate base plate oriented with a midline of the base plate longitudinal on the occipital bone. A pair of lateral sections project in opposite directions from the central section and include attachment assemblies for securing a rod to the occipital plate. The position of the attachment assembly relative to the midline of the occipital plate is adjustable to thereby provide for medial-lateral adjustability. In specific embodiments, the attachment assemblies include a slide member which mates with the lateral section of the occipital plate in a dove-tail joint configuration and a set screw is threadably engaged with the slide member to secure the slide member relative to the midline of the occipital plate and the appropriate spacing and geometry for the specific patient. The set screw also secures a cam, which fixes the rod to the occipital plate.
