Abstract: A radiation shield is fixed to scanning equipment at a location that attenuates a moving beam of radiation only while the beam passes over a relatively vulnerable portion, especially anterior portion, of the patient's body. Such an in-plane shield can be selective as to radiation wavelength attenuation. As an example, for scanners that use X-rays, the low energy portion of the spectrum can be selectively blocked while the high energy portion of the spectrum passes through to the patient and detector. When embodied in a CT X-ray scanner, the selective attenuation can be achieved with a thin slice bismuth shield/filter permanently installed on at least the anterior quadrant of the gantry, preferably on a span of approximately about 140 deg. in registry with the circular path of the source.

Abstract: A system of non-reactive components for moving or for moving and stretching plastic tissue that exerts a relatively constant dynamic force over a variety of distances and geometries, that is easily adjustable, and is self-adjusting. This system includes a “button anchor system” for moving tissue, particularly including deep fascia and muscle layers of the abdominal or thoracic cavity wall, in surgical, post surgical, and post traumatic reconstruction where the wound margins are beyond a distance that permits normal re-approximation. Button anchor assemblies allow re-approximation of severely retracted abdominal wall and full thickness thoracic wounds where a closure force is required to be applied to the sub-dermal layers. Systems of this invention allow for such a force to be applied and externally controlled during treatment.

Abstract: A composite viscera protector consisting of a silicone layer, a polypropylene mesh layer and an additional silicon layer having a thickness between 0.5 and 2.53 mm, with a repeating series of holes in a pattern over its entire surface or a portion thereof with the holes being slits on one or two planes non-intersecting and being of a size between 1 and 10 mm.

Abstract: A repair fixture for supporting large cylindrical objects such as a generator rotor, to facilitate field maintenance operations. The fixture has two spaced Vee-blocks that are supported by and moved within vertical channels formed within peripheral stanchions. Clevises are rotatably connected at one end to both lateral sides of the Vee-block and at the other end to a hydraulic piston that is employed to raise and lower the Vee-blocks in unison to accommodate various maintenance requirements.

Abstract: A scalpel assembly utilizing an ejectable blade allowing easy installation and removal of the blade. Use of an ejectable blade permits a used or contaminated blade to fall freely from the scalpel assembly without direct contact with the blade.

Abstract: An apparatus comprises: a first cylindrical handle rotatable about a first cylindrical axis; a second cylindrical handle rotatable about a second cylindrical axis disposed such that the first handle and the second handle form an angle of less than 180 degrees; and a resistance adjuster operable to adjust a rotational resistance of the first handle about the first cylindrical axis and the second handle about the second cylindrical axis.

Abstract: The invention relates to a hazer system that includes a base unit, an air capture unit and an air return line. The base unit is configured to hold a haze fluid and produce a haze, and has one or more outlets from which the haze is emitted. The air capture unit has one or more openings through which a negative pressure exists to capture at least a portion of the haze produced by the base unit. The air return line is configured to return at least a portion of the captured haze to the base unit and/or exhaust at least a portion of the capture haze.

Abstract: An improved scissor-type clamp includes two opposing clam shell type members, one male and one female, that pivot together, are biased outwardly by coil springs and are held together by a thumbscrew. Embodiments feature rectangular and tapered opposed clam shell portions and one embodiment includes identical clam shell members.

Abstract: A system and method of moving and stretching plastic tissue using dynamic force. An elastomeric driver is adjustably attachable to one or more anchors for securing the elastomer to the plastic tissue, providing a self adjusting system that is capable of exerting relatively constant tension over a certain distance.

Abstract: A bottle holder that is unbalanced when its base surface is placed on a horizontal surface but is balanced on the base surface when a neck of a bottle is received and position in an opening provided in the holder. The opening which extends from a front side to a rear side is generally oval in shape on the front side but only partially oval on the back side wherein the top portion of the partial oval comprises a horizontal linear edge. This edge helps stabilize the bottle's neck within the opening making it easier for a user to locate the bottle's neck at the proper location in the opening to facilitate the balanced combination.

Abstract: A fixation and retraction system utilizing base components to which shielded magnet components attach in order to locate movable fixation and retraction components or other operating theater devices, such as surgical drapes. Use of rare earth magnets permits system components to be attached quickly, easily and securely in almost an infinite number of configurations.

Abstract: Systems and methods for manipulation and stabilization of tissue and other structures during surgical and other specialized procedures. Components of the systems of this invention are widely applicable in both veterinary and human medicine, including procedures involving small or delicate structures or tissues requiring precise manipulation or stabilization, procedures requiring substantial retractive forces without causing tissue damage and procedures that benefit from exoskeletal retraction. Fixation components, which couple dynamic components and retraction or positioning components to base components, are easily adjustable, allowing manipulation of the system with one hand. Length and orientation of retraction or positioning components is also easily adjustable in several ways.
