An integrated catheter placement system for placing a catheter in a vasculature of a patient. The system includes a system console with a tip location mode and an ultrasound mode viewable on a display, a magnetic assembly emanating a magnetic field, a tip location sensor designed to sense the magnetic field, and an ultrasound probe for ultrasonically imaging an internal portion of the patient. The magnetic field may provide magnetic field information for locating the magnetic assembly relative to the tip location sensor. The tip location sensor is designed to communicate the magnetic field information to the system console. The system console is designed to display an icon representative of a location of the magnetic assembly relative to the tip location sensor in the tip location mode.

In a biopsy needle having a hollow tubular outer needle, an inner needle that is disposed in a hollow portion of the outer needle so as to be movable in the tube axis direction relative to the outer needle, and a recessed sample collection portion that is cut inward from a circumferential surface of the inner needle, an inner hole that extends in the longitudinal direction of the inner needle on each of the inner needle distal end side and the inner needle rear end side of the sample collection portion and are opened to the sample collection portion is provided in the inner needle, and a light guide member is disposed in the inner holes. At least a part of the light guide member is fixed by filler filled in the inner holes.

Described embodiments include apparatus that includes a signal generator and an electric circuit. The signal generator is configured to supply a signal having both a first dominant frequency and a second dominant frequency. The electric circuit, which includes a reactive component, is configured to generate, upon the signal being supplied to the electric circuit, a magnetic field having both the first dominant frequency and the second dominant frequency, by virtue of the reactive component simultaneously resonating at both the first dominant frequency and the second dominant frequency. Other embodiments are also described.

A catheter with a distal end that rotates through the conversion of linear motion to rotational motion, thus the distal end may be rotated without longitudinally advancing or retracting the distal end. The catheter includes a tube with a single helix or a dual chirality helix cut into the tube, a distal end segment, means for linear displacement of the helix, and means for coupling the junction point of the helix to the distal segment.

A diagnosis support system includes a calculator configured to calculate position information indicating a positional relationship between a biological sensor and a predetermined region of a measurement target; and an extractor configured to extract, from biological information already diagnosed, biological information that is associated with position information, which is similar to the position information calculated by the calculator.

A system and method are provided for performing fluoroscopic procedures with assistance of guiding laser beam projections to reduce a reliance on harmful radiation emitting fluoroscopic imaging devices during the procedure. The system and method reduce an amount of radiation exposure to patients and medical personnel during procedures that require assistive real-time imaging. Specifically, an automated laser guidance system and method of use is provided to reduce fluoroscopic radiation, reduce operation time, and increase operative accuracy.

A system and method for tracking completeness of co-registered medical image data is disclosed herein. The system and method tracks the position of an anatomical reference marker positionable on a patient and an ultrasound probe during an imaging session and co-registers medical images based on positional data received from the anatomical reference marker and the ultrasound probe. Using the co-registered image data, the system and method generates a surface contour of a region of interest (ROI) of the patient, such as a breast. The surface contour is defined to represent an interface between a chest wall structure and tissue of the ROI in a plurality of co-registered medical images. A completeness map of the image data within the defined surface contour during the imaging session is generated and overlaid on a graphic representation of the ROI.

A framework for image-based probe positioning is disclosed herein. The framework receives a current image from a probe. The current image is acquired by the probe within a structure of interest. The framework predicts a position of the probe and generates a recommendation of a next maneuver to be performed using the probe by applying the current image to a trained classifier. The framework then outputs the predicted position and the recommendation of the next maneuver.

Embodiments of the present invention provide for maintaining a level set of a pulmonary artery catheterization apparatus that includes a pulmonary artery pressure sensor in communication with a pulmonary artery catherization manifold affixed to a pulmonary artery catheter. The method includes calibrating leveling of the pulmonary artery pressure sensor (at the level of the right atrium) with the pulmonary artery catheterization manifold by recording a vertical level of a leveling base positioned at a common level to the manifold, relative to a vertical level of a leveling sensor positioned at a common level to the pulmonary artery pressure sensor. The method further includes monitoring a difference between the recorded vertical level of the leveling base relative to the vertical level of the leveling sensor. Finally, the method includes generating an alert in a user interface element of the leveling sensor in response to the monitored difference exceeding a threshold value.
