Various embodiments relate to a microbeam radiation therapy (microbeam radiosurgery) system, including: a radiation beam source; a collimator with slits, wherein the collimator only passes a radiation beam from the radiation beam source through the slits; a filtering and limiting system; a source shutoff controller connected to the radiation beam source; and a detector configured to detect events requiring the shutdown of the radiation beam source.

Safety methods and apparatus for low dose-rate radiation for medical and veterinary therapies

An inter-vertebral implant having a hollow frame having a top load bearing surface and a bottom load bearing surface may be inserted between a first spinal vertebra and a second spinal vertebra. The top load bearing surface and the bottom load bearing surface may each include an opening allowing access to the interior of the frame. A front surface may extend between the top load bearing surface and the bottom load bearing surface, and a rear surface may extend between the top load bearing surface and the bottom load bearing surface. A plate is attached to the front surface of the support device. The interior front plate may be arranged along a plane (P), and an axis (A) between the top load bearing surface and the bottom load bearing surface may be at a non-right angle relative to the plane (P).

Inter-vertebral implant with angled plate

Various embodiments relate to a method of performing microbeam radiation therapy (microbeam radiosurgery) for a subject, including: producing a high-energy radiation beam; shaping, attenuating, strengthening, hardening and/or otherwise appropriately modifying the high-energy radiation beam using a low-Z, high-Z, or variable-Z filter; passing the beam before or after it has been so modified through a collimator to produce high-dose regions alternating with low-dose regions; and irradiating the subject with the collimated beam so modified.

Low dose-rate radiation for medical and veterinary therapies with three dimensionally shaped profiles

Various embodiments relate to a method of performing microbeam radiation therapy on a subject, including: producing a high-energy radiation beam in a first direction; producing planar microbeams using the high-energy radiation beam in the first direction, wherein the microbeams have a width, wherein the planar microbeams produce scattered electrons; and applying a magnetic field in a direction lying in a plane substantially parallel to the planar microbeams, wherein the strength of the magnetic field corresponds to the width of the microbeam.

Magnetic confinement for microbeam radiation damage area

Various exemplary embodiments relate to a spinal implant for insertion between two adjacent vertebrae, the spinal implant including one or more of the following: a cage comprising: a frame sized to be inserted between the vertebrae, the frame comprising a fastener hole and a cage alignment structure, the cage alignment structure comprising at least one of: a cage groove and a cage ridge; a bone plate comprising a bone plate alignment structure a through hole, wherein the bone plate alignment structure comprises at least one of a bone plate groove and a bone plate ridge, and wherein the bone plate alignment structure and the cage alignment structure are configured to interact with each other to provide an indication when the bone plate is properly aligned with the cage; and a fastener to attach the bone plate to the cage when inserted through the through hole and into the fastener hole.

Bone plate and fusion cage interface

An anterior cervical column support having a hollow frame having a top load bearing surface and a bottom load bearing surface may be inserted between a first spinal vertebra and a second spinal vertebra. The top load bearing surface and the bottom load bearing surface may each include an opening allowing access to the interior of the frame. A front surface may extend between the top load bearing surface and the bottom load bearing surface, and a rear surface may extend between the top load bearing surface and the bottom load bearing surface. Two side surfaces are attached between the front surface and the rear surface, each side surface having a solid side panel that is at least x-ray translucent. An anterior (front) plate is attached to the front surface of the support device, where the front plate includes clearance holes for receiving fasteners for holding the front plate in position. The top load bearing surface and the bottom load bearing surface may include a serrated or other high friction surface for applying frictional forces between the load bearing surfaces and adjacent vertebrae.

Vertebral spacer

Various embodiments relate to a method of performing microbeam radiation therapy on a subject, including: affixing a collimator to the subject at a first location; producing a first high energy radiation fan beam, wherein the width of the first fan beam in a first direction is greater than the width of the first fan beam in a second direction; and moving the subject in the second direction so that the first fan beam irradiates the subject through the collimator to produce first high dose regions alternating with first low dose regions.

Low dose-rate radiation for medical and veterinary therapies

An implant unit used in surgery has a body made from osteogenic implantable material and including an implant portion and a retaining portion, which is coupled to and extends transversely to the implant portion. The retaining portion is attached to the sidewall of the adjoining vertebral body or mammal bone to prevent displacement of the implant portion relative to the vertebral body or mammal bone and to accelerate fusion therebetween.

Intervertebral implant with movement resistant structure

A bone plate for securing a spinal fixation element to bone includes a base portion having a top face, a rod receiving portion and a bone anchor receiving portion. The bone anchor receiving portion includes a plurality of angled holes for receiving bone screws. At least one of the screw holes is oriented at an acute angle relative to the top face of the plate.

Minimal access occipital plate

A device, system and method for securing a plate to a bone. An anchor device has a screw (with a head portion) and a locking disc. The head portion includes a slotted wall defining a plurality of petals disposed around a central opening. The screw further includes an internal bore. The locking disc is rotatably disposed within the central opening, such that in a first rotational position the petals may flex inwardly, and in a second rotational position the petals are substantially prevented from flexing inwardly. A tool for manipulating the anchor device has a shaft with its end configured to mate with the internal bore of the screw to permit selective rotation of the screw, and a sleeve member rotatably and slideably mounted on the shaft having an end that mates with the locking disc to permit selective rotation of the disc.

Cervical plate system

Guide conduit device
