Abstract: An external fixator includes a main body and an outrigger for extending over a fractured joint, such as a wrist joint. The main body can be positioned next to a right arm, or flipped over and positioned next to a left arm. The outrigger is attachable to extend either to the left or to the right of the main body, as appropriate. A distal body is removeably connectable to the distal end of the main body, and the distal body can be affixed to bone on the opposite side of the fracture to immobilize the joint where the fracture occurs. The distal body is connected to the main body with an adjustable securement section which provides six degrees of adjustment freedom. The outrigger is attached to the main body through a slide plate in a dual rail configuration which provides two dimensions of adjustment. Fragment pin supports ride in a track of the outrigger, and provide seven degrees of adjustment freedom for directed fixation of fragments at the fracture site.

Abstract: An external fixator for treating a fracture of a long bone has six extension arms which are extendable out of and retractable into a main body. The six extension arms are arranged into two sets of three out opposing sides of the main body, with each set of three extension arms being able to support a fixation ring. Each extension arm is pivotable at a joint and extendable so as to allow the ring to be set at a wide range of angular positions relative to the main body. The three extension arms and the ring each define a wrap angle about the axis of the long bone being treated. The longitudinal position of each extension arm can be changed either with a coarse adjustment capability or with a fine adjustment capability, with the coarse adjustment capability being through rotation of a thumb wheel.

Abstract: A device and method to mechanically strengthen bone matrix and deliver tissue reinforcement material to weakened areas in skeletal structures. A preferred embodiment is an orthopedic screw configured to receive and directionally disperse a therapeutic fluid through the screw's channels and apertures.

Abstract: A concentrator is used for concentrating a fluid, particularly a plasma component out of blood, for treatment of a patient. The concentrator apparatus includes a main housing defining a centrifuge chamber, that also holds the filter. The concentrator allows viewing of the fluid after centrifuging, with an outlet port positionable at a height corresponding to the level of the fraction of the fluid to be further concentrated. Once the fluid is centrifuged, a portion of the fluid is drawn through the outlet, and then pressured past the filter to further concentrate the fluid using the same vessel as used for centrifuging. The same plunger is preferably used to draw centrifuged fluid from the centrifuge chamber as to pressure the centrifuged fluid past the filter.

The six extension arms are also arranged into three opposing pairs, with each pair of extension arm shafts is disposed in an abutting relationship in the main body such that the extension arm shafts extend or retract out opposing sides of the main body.

Abstract: A convertible threaded compression device connects a bone fragment to an anchor bone for a healing duration. The compression device has a distal bone penetration section which is advanced into the bone and a proximal bone exterior section. The proximal bone exterior section is longer than the bone penetration section, and thus extends substantially out of the bone during healing of the bone. The bone penetration section includes a distal bone anchor section which threadingly engages the anchor bone, and a proximal fragment section of smaller diameter. The fragment section fits within the overbore created by advancing the bone anchor section through the bone fragment, and thus extends through but does not positively engage the bone fragment. A compression engagement on a distal end of the bone exterior section provides a compression shoulder.

Abstract: An external fixator includes a main body and an outrigger for extending over a fractured joint, such as a wrist joint. The main body can be positioned next to a right arm, or flipped over and positioned next to a left arm. The outrigger is attachable to extend either to the left or to the right of the main body, as appropriate. A distal body is removeably connectable to the distal end of the main body, and the distal body can be affixed to bone on the opposite side of the fracture to immobilize the joint where the fracture occurs. The distal body is connected to the main body with an adjustable securement section which provides six degrees of adjustment freedom. The outrigger is attached to the main body through a slide plate in a dual rail configuration which provides two dimensions of adjustment. Fragment pin supports ride in a track of the outrigger, and provide seven degrees of adjustment freedom for directed fixation of fragments at the fracture site.

Abstract: A bone fragment wire connects a bone fragment to an anchor bone for a healing duration. The bone fragment wire has a distal bone penetration section which is advanced into the bone and a proximal bone exterior section. The proximal bone exterior section is longer than the bone penetration section, and thus extends substantially out of the bone during healing of the bone. The bone penetration section includes a distal bone anchor section which threadingly engages the anchor bone, and a proximal fragment section of small diameter. The fragment section fits within the overbore created by advancing the bone anchor section through the bone fragment, and thus extends through but does not positively engage the bone fragment. A compression engagement on a distal end of the bone exterior section provides a compression shoulder. In one embodiment the compression engagement is provided by a threaded compression nut, while in another embodiment the compression engagement is permanent affixed to the bone wire.
