20180008295 · 2018-01-11 ·

Catheter-delivered endovascular medical devices are described. The devices may include a pull wire attached to a distal body. The distal body may be formed of a distal body outer body comprising a basket comprised of a plurality of cells defined by a plurality of basket strips and a distal body inner body located in the interior of the distal body outer body and comprising a plurality of distal braided mesh openings formed by a plurality of woven linear strands. The distal braided mesh openings may be smaller than the cells when the device is in the relaxed state. Methods of using and making the devices are also described.

Automatic probe reinsertion

In accordance with one embodiment, an automated probe system includes a probe configured to be reversibly inserted into a live body part, a robotic arm attached to the probe and configured to manipulate the probe, a first sensor configured to track movement of the probe during an insertion and a reinsertion of the probe in the live body part, a second sensor configured to track movement of the live body part, and a controller configured to calculate an insertion path of the probe in the live body part based on the tracked movement of the probe during the insertion, and calculate a reinsertion path of the probe based on the calculated insertion path while compensating for the tracked movement of the live body part, and send control commands to the robotic arm to reinsert the probe in the live body part according to the calculated reinsertion path.

LIVING TISSUE SAMPLING METHOD AND BIOPSY SUPPORT SYSTEM

A living tissue sampling method includes inserting an endoscope inserted into a guide sheath into a body cavity of a subject, checking three-dimensional image information of a body cavity path against distal end position data of the endoscope, bringing distal ends of the endoscope and the guide sheath close to a focused region, removing the endoscope from the guide sheath while keeping the guide sheath stationed inside the body cavity, inserting a biopsy instrument into the guide sheath, and sampling living tissue of the focused region by the biopsy instrument.

System and method for identifying and marking a target in a fluoroscopic three-dimensional reconstruction

A method and system for facilitating identification and marking of a target in a displayed Fluoroscopic Three-Dimensional Reconstruction (F3DR) of a body region of a patient. The system includes a display and a storage device storing instructions for receiving an initial selection of the target in the F3DR, fining the F3DR based on the initial selection of the target, displaying the fined F3DR on the display, and receiving a final selection of the target in the fined F3DR via a user selection. The system further includes at least one hardware processor configured to execute said instructions. The method and instructions may also include receiving a selection of a medical device in two two-dimensional fluoroscopic images, where the medical device is located in an area of the target, and initially fining the F3DR based on the selection of the medical device.

Apparatus for fiducial-association as part of extracting projection parameters relative to a 3D coordinate system

A registration fixture or plate is configured for use with a medical imaging system. The registration fixture may be an optical magnetic registration plate including a plurality of fiducial markers in arranged in a predefined unique pattern. The pattern can be unambiguously detected on 2D image of the plate produced by the medical imaging system. Association of the 2D imaged pattern of fiducial markers with the actual 3D pattern on the optical magnetic registration plate allows for accurate calculation of projection matrices and co-registration of the 3D and 2D coordinate systems.

Monitoring handling of an object

In order to reduce a radiation dose delivered to an object or an observer, a facility for monitoring handling of the object has an optical unit configured to direct ionizing radiation onto the object and also a filter element in order to attenuate a part of the ionizing radiation. An imaging unit may detect portions of the ionizing radiation passing through the object in order to create an image of the object. A view acquisition system may acquire a viewing movement, and a control unit is configured, during a first operating mode, to control a position of the filter element as a function of the viewing movement. The control unit is configured to identify a predefined sequence of viewing movements and, as a function thereof, to switch into a second operating mode. The position of the filter element is controlled during the second operating mode as a function of an image analysis.
