    Abstract: Repeat fixation for medical procedures is accomplished using a non-invasive locator, specifically a bite plate (26). The bite plate (26) has at least three fiducial markers (38) on it. The fiducial markers (38) may be LEDs, radiopaque markers for angiography or computerized tomography (CT) imaging or magnetic resonance markers for magnetic resonance (MR) imaging. By detecting the position of the markers (38), the position of features within the patient (14) (such as a brain tumor or other intracranial target to which radiation is to be applied) can be determined with great precision. Since the bite plate (26) has been molded to uniquely fit to the patient's teeth, it may be removed after an initial imaging of the patient (14). The bite plate (26) may then be re-attached one or more times to the teeth and the location of the features will be in a known position relative to the sensed markers.

    Abstract: A catheter (10) uses a steerable outer catheter (12) with an inner catheter (14) rotatable and extendable with respect to the outer catheter (12). The outer catheter (12) may be positioned within a patient's heart and a portion of the outer catheter (12) may provide movement like that of a windshield wiper by manipulation of a spring. By combining a windshield-wiper-type movement with the extension and rotation of the inner catheter (14) relative to the outer catheter (12), a large area within a patient's heart may be readily mapped for conduction tissue and be subjected to laser ablation if appropriate. Various configurations provide flexibility in relatively positioning of windows used to apply laser energy and ring electrodes (20F and 20S) used to sense conduction tissue.

    Abstract: Described are proteins having molecular weights of 85 and 160 kDa, which proteins are responsive to cold acclimation or drought stress in plants. The cDNA for the 85 and 160 kDa proteins, designated CAP85 and CAP160, are disclosed. Transgenic cells, including microorganisms and plants, can be produced which express the CAP85 and CAP160 proteins and thereby advantageously enhance the cold or water stress tolerance in the transgenic organism. Freeze and desiccation damage can also be prevented by applying a cold acclimation protein to the organism needing such protection.

    Abstract: A contrast agent useful for imaging a sample comprising a suspension in a medium acceptable for imaging (a) particles of a contrast agent possessing paramagnetic characteristics and (b) particles of a contrast agent possessing diamagnetic characteristics. Also disclosed is a method of imaging a sample which comprises introducing into the sample the above-described contrast agent and generating a substantially artifact-free image thereof. The combination of diamagnetic barium sulfate and superparamagnetic iron oxide (SPIO) in one suspension produces a macroscopic cancellation of positive and negative magnetic susceptibility components which eliminates susceptibility artifacts even with gradient echo pulse sequences. The relaxation properties which make the SPIO suspension a useful negative contrast agent are retained.

    Abstract: A fluid transfer device (20) for safely transferring fluid from a needleless collection device (28) to a separate container (32). The device includes a housing (10) having a passage (16) therethrough and an integral needle (22). A first, connection section (18) of the housing is adapted to connect to a needleless collection device (28) from which fluid is to be transferred and a second, shield section (20) of the housing is adapted to accept the container (32) into which fluid is to be transferred. One end (24) of the needle is formed integrally with the connection section (18) of the housing. The penetration end (26) of the needle extends into the shield section (20) of the housing (10) and is fully covered by the shield section (20). When a container (32) is inserted into the shield section (20) of the housing (10) the needle enters the container and fluid may be transferred from a collection device (28) connected to the connection section (18) of the housing.

    Abstract: Stereotactic radiosurgery apparatus for eliminating misalignments due to mechanical inaccuracies and sag of a linear accelerator radiation-emitting head which is swung through an arc comprises a guiding and support structure (54) with a first bearing system for accurately rotating a collimator (32) through a precise arc in a vertical plane (30) with respect to a predetermined center point (34) in the plane corresponding to a treatment location, a second gimbal bearing system (70) for coupling the collimator (32) to the head (16) so that the rotating head can drive the collimator (32) through its arc while mechanically uncoupling the head from the collimator by eliminating torques and forces on the collimator which would be exerted by mechanical inaccuracies or sag of the head, and a third bearing system (86) for rotatably supporting a stereotactic floorstand (28) for rotation about a vertical axis (30) which intersects the center point. Since the movement of the collimator (32) and the rotation of the floorstand are precisely controlled with respect to the center point, the apparatus ensures that radiation from the head will be accurately focused at the center point (34) for all rotational positions of the head and floorstand. Mechanical linking arrangements are shown for allowing the floorstand to rotate automatically upon rotation of a patient treatment table (20). Although the linking arrangements are used to drive the rotation of the floorstand, the linkage arrangements prevent the introduction of positional inaccuracies in the floorstand rotation.
