摘要: Physicians performing invasive procedures utilize instruments inserted into a human body to perform the procedures. Such procedures typically involve actions to be performed on specific targeted anatomical structures. During the procedure, nearby anatomical structures unrelated to the procedure should generally be avoided. A system and techniques are provided herein for monitoring the position of such unrelated nearby anatomical structures relative to one or more surgical instruments. The system emits a warning to a human operator such as a surgeon if one of the instruments is too close to a monitored anatomical structure.

摘要: The present application describes techniques to image biological tissue to determine biological information of an imaged tissue sample such as changes in hemoglobin concentrations, blood flow rate (pulse), and/or spatio-temporal features. Embodiments include illuminating the tissue sample with light in the near-infrared (NIR) spectrum, which is minimally absorbed but scattered through the tissue sample. By detecting the NIR light that is attenuated through, transmitted through, and/or reflected off the tissue to be imaged, the resulting NIR intensity signals may be further analyzed to provide this data. Embodiments include using multiple NIR light sources having varying wavelengths to obtain changes in the oxy- and deoxy-hemoglobin concentrations of the imaged tissue region. The tissue sample may be imaged over a time period, and the NIR images may be viewed statically or in real time after post-processing analyses have been performed.

摘要: A system for generating a manual input on a shape sensing fiber includes a shape enabled device (102) including one or more shape sensing optical fibers. An input device (106) is configured on a portion of the one or more shape sensing optical fibers, wherein a change in optical shape sensing data associated with the input device distinguishable from other shape sensing data, generates an input signal. A processor system (112) is configured to receive the input signal and perform an action responsive to the input signal.

摘要: This invention relates to a method of catheter and radiating coil location in a human body. In particular, when a radiating coil is used in conjunction with a catheter, a coil locating device can be used to determine the distance the coil is from the device and its depth in the patient's body. A display is provided that shows both a reference image of a portion of a non-subject body and an image of the coil located on the display with reference to the reference image. This is achieved by locating the coil-locating device on a predetermined landmark on the patient's body. The coil and its signal wires can be incorporated into a stylet, guide wire or a catheter. The coil locating device can be orientated towards the head of the patient and for an axis of the device to be aligned with the mid sagittal plane of the patient.

摘要: A method includes, identifying, in a three-dimensional (3D) anatomical image of a patient organ, multiple anatomical points corresponding to respective predefined locations on a skin of the patient organ in a first coordinate system. Multiple positions in a second coordinate system, measured by a position sensor of a position-tracking system at the respective predefined locations on the skin of the patient organ, are received. At each predefined location, a distance is calculated between a respective anatomical point and closest bone tissue of the patient organ. Weights are assigned to the predefined locations based on respective distances between the anatomical points and the closest bone tissue. The first and second coordinate systems are registered, by correlating between the positions and the respective anatomical points using the assigned weights.

摘要: Disclosed are devices, systems, and methods for determining the dipole densities on heart walls. In particular, a triangularization of the heart wall is performed in which the dipole density of each of multiple regions correlate to the potential measured at various located within the associated chamber of the heart. To create a database of dipole densities, mapping information recorded by multiple electrodes located on one or more catheters and anatomical information is used. In addition, skin electrodes may be implemented. Additionally, one or more ultrasound elements are provided, such as on a clamp assembly or integral to a mapping electrode, to produce real time images of device components and surrounding structures.

摘要: An algorithm to correct and/or scale an electrical current-based coordinate system can include the determination of one or more global transformation or interpolation functions and/or one or more local transformation functions. The global and local transformation functions can be determined by calculating a global metric tensor and a number of local metric tensors. The metric tensors can be calculated based on pre-determined and measured distances between closely-spaced sensors on a catheter.

摘要: A system includes a plurality of RFID chips affixed to a medical item, a device reader such as a data collection engine device, and a server device. The data collection engine wirelessly transmits power to an RFID chips and receives first medical data from the RFID chip while the RFID chip is activated by the power receiver. The data collection engine generates a first message indicative of the first medical data to be sent to the server device. The server device can determine aspects of the medical item such as position and risk states based upon the first medical data.
