Devices and methods divert blood flow from a first vessel to a second vessel and maintain blood flow in the first vessel. The device includes a first segment and a second segment. The first segment is configured to anchor in the first vessel. The first segment includes a window to allow blood to flow into the first segment, through the window, and distal in the first vessel. The second segment is configured to anchor in the second vessel. The second segment is configured to allow blood to flow into the first segment, through the second segment, and into the second vessel.
APPARATUS AND METHOD FOR PASSIVE MARKERS LOCALIZATION WITHIN A BODY
A system for localizing a region of interest (ROI) within a patient's body is disclosed. An embodiment of the system may comprise a pad that can be placed in association with the patient's body; one or more markers which are placed within a patient's body in association with the ROI, each marker being associated with one or more antennas and a unique collective ID; a locator comprising one or more antennas for transmitting/receiving a microwave (MW) signal into/from the patient's body in order to identify the one or more markers and a processing unit that is configured to control the operation of the system and for determining the distance from the locator to each one of the one or more markers.
MEDICAL OBJECT FOR ARRANGEMENT IN AN OBJECT UNDER EXAMINATION AND SYSTEM FOR SENSING A MEDICAL OBJECT
A medical object for arrangement in an object under examination includes an optical fiber. The optical fiber is configured to contact at least one light source optically. The medical object further includes multiple photoacoustic absorbers that are arranged in sections along a direction of longitudinal extension of the optical fiber and/or along a periphery of the medical object. The multiple photoacoustic absorbers are configured to be arranged at least in part in the object under examination. The optical fiber is configured to conduct an excitation light emitted by the at least one light source to the multiple photoacoustic absorbers. The multiple photoacoustic absorbers are configured to be excited by the excitation light for the photoacoustic emission of ultrasound.
SURGICAL POWER DRILL SYSTEM
A surgical power drill system includes a housing unit, a driving unit, a tool holder, and a screw member. The driving unit is movably mounted in the housing unit and includes a motor and a motor shaft coupled to the motor. The driving unit is movable relative to the housing unit between a distal position, where the driving unit is distal from a front end of the housing unit, and a proximate position, where the driving unit is proximate to the front end of the housing unit. The tool holder is coupled to a first end portion of the motor shaft. The screw member is coupled to a second end portion of the motor shaft.

ULTRASOUND MARKER, ULTRASOUND MARKER SYSTEM AND METHOD OF OPERATING AN ULTRASOUND MARKER SYSTEM
The invention refers to an ultrasound marker that comprises an enclosure. The marker comprises an energy transducer for transducing impeding sound energy into electric energy. The marker also comprises an ultrasound emitter that is configured to generate an ultrasound signal when fed with electric energy. The marker further comprises a trigger that is operatively connected to the ultrasound emitter and that can be activated via a wireless signal. The trigger is configured to control the generation of ultrasound by the ultrasound emitter in dependence of the wireless signal.
Simulated bone or tissue manipulation
The present invention is directed to a system and method for performing tissue, preferably bone tissue manipulation. The system and method may include implanting markers on opposite sides of a bone, fractured bone or tissue to facilitate bone or tissue manipulation, preferably in-situ closed fracture reduction. The markers are preferably configured to be detected by one or more devices, such as, for example, a detection device so that the detection device can determine the relative relationship of the markers. The markers may also be capable of transmitting and receiving signals. An image may be captured of the bone or tissue and the attached markers. From the captured image, the orientation of each marker relative to the bone fragment may be determined. Next, the captured image may be manipulated in a virtual or simulated environment until a desired restored orientation has been achieved. The orientation of the markers in the desired restored orientation may then be determined. The desired relationship between markers may then be programmed into, for example, the detection device. Next, actual physical reduction and/or manipulation of the bone may begin. During the manipulation procedure, the orientation of the markers may be continuously monitored and when the markers substantially align with the virtual or simulated orientation of the markers in the desired restored orientation, an indicator signal is transmitted.
3D tracking of an interventional instrument in 2D ultrasound guided interventions
An interventional instrument (30) having ultrasound sensors (S1, S2, S3, S4, . . . ) is tracked using an ultrasound imaging device (10) that acquires and displays a 2D ultrasound image of a visualization plane (18), and performs 2D ultrasound sweeps for a range of plane angles (θ) obtained by rotating the ultrasound probe (12) and encompassing the visualization plane angle. For each ultrasound sensor, an optimal plane is found based on its emitted signal strength over the range of plane angles, and the ultrasound sensor is located in its optimal plane by analyzing the sensor signal as a function of the timing of the beams fired by the ultrasound probe. These locations in their respective optimal planes are transformed to a 3D reference space using a transform (42) parameterized by plane angle, and a visual indicator is displayed of spatial information (T, L) for the interventional instrument generated from the locations of the one or more ultrasound sensors in the 3D reference space.
Interventional device with piezoelectric transducer
An interventional device includes an elongate shaft and a transducer strip. The transducer strip includes a first edge and an opposing second edge. The first edge and the second edge are separated by a width dimension, and the first edge and the second edge each extend along a length direction of the transducer strip. The transducer strip also includes a piezoelectric transducer that extends along a transducer direction that forms an acute angle with respect to the length direction. The transducer strip is wrapped in the form of a spiral around the elongate shaft of the interventional device such that the piezoelectric transducer forms a band around the elongate shaft. The width dimension is defined such that the adjacent first and second edges of consecutive turns of the spiral abut or overlap one another.
