Abstract: An application or an attachment device for attaching a medical device includes a base layer and an adhesive layer on a rearward side of the base layer. The adhesive layer is adapted to removably attach the base layer. The adhesive layer can be adapted to removably attach the base layer to a patient (either a human patient or a lower animal patient). The device also includes a medical device attachment mechanism on a forward side of the base layer, The attachment mechanism is adapted to attach the medical device to the base layer. The medical device can, for example, be a sensor. The medical device attachment mechanism can, for example, include a mechanical attachment mechanism. The medical device attachment mechanism can additionally or alternatively include at least one adhesive layer on the base layer. The adhesive layer can, for example, be positioned on the base layer so that it does not extend beyond a footprint of the medical device when the medical device is attached to the base layer.

Abstract: Systems and methods for discriminating and locating tissues within a body involve applying a waveform signal to tissue between two electrodes and measuring the electrical characteristics of the signal transmitted through the tissue. At least one of the electrodes is constrained in area so that localized electrical characteristics of the tissue are measured. Such localized electrical characteristics are determined over a portion of a body of the subject by using an array of electrodes or electrodes that can be moved over the body. A controller may implement the process and perform calculations on the measured data to identify tissue types and locations within the measured area, and to present results in graphical form. Results may be combined with other tissue imaging technologies and with image-guided systems.

Abstract: A tissue dissociation device (10) includes a container (12) having a sterile interior for holding the tissue to be dissociated and a liquid medium. The device (10) also includes a dissociation element (54), inside the container (12), for engaging the tissue to cause dissociation of the tissue. The device (10) also includes a resistive element (81), inside the container (12), for resisting movement of the tissue in response to the engagement by the dissociation element (54). Relative motion between and the resulting resistance provided by the resistive element (81) allows the dissociation element (54) to effectively dissociate the tissue. A powered tissue dissociation device includes a power source operatively connected to the dissociation element (54) for causing the dissociation element (54) to move into engagement with the tissue.

Abstract: System and apparatus for locating sources of radiation emanating from predetermined radionuclides. The apparatus incorporates a large window display utilizing icon imagery to identify counting functions such as target count and background. A variety of radionuclide modes of operation can be selected by the operator and the system automatically defaults to detector bias selection and window reference voltage selection in correspondence with the elected radionuclide. A bar graph readout apprises the user of the amount of time or count level remaining in a target or background procedure and the flashing of icon identifiers occurs during such procedures. Pulse validation is improved by the utilization of a discriminator which evaluates pulse width.

Abstract: A surgical probe wherein a heat sterilizable and reusable detector component is combined with a disposable handle and cable assembly. The reusable detector component incorporates a detector crystal and associated mountings along with preamplifier components. It is formed having a positioning shaft extending therefrom to a contact supporting surface carrying a pattern of electrical contact surfaces. Two orientation bosses are formed with the positioning shaft. The disposable handle employs an insert member having a receiving cavity. The electrical contact carrying tip of the shaft engages an elastomeric seal and moves into electrical engagement with a pattern of electrical contacts mounted within the handle in conjunction with a permanently affixed flexible cable.
