摘要： A system and method for compensation of angular distortions in a system utilizing light emitters and light sensors disposed on non-parallel jaws may include determining a first point at a first side of a region of interest and a second point at a second side of the region of interest, determining a linear curve including the first and second points, and utilizing the linear curve to remove the angular distortion from the region of interest between the first and second points. A system and method for compensation of angular distortions may alternatively include modeling a non-pulsatile illumination pattern according to the intensities of individual emitters, comparing the pattern according to the model against a non-pulsatile illumination pattern detected using the light sensors, and varying the intensities of the individual emitters based on the comparison until angular distortion has been removed.

摘要： Intravascular imaging systems and methods for making and using intravascular imaging devices are disclosed. An example intravascular imaging device may include an imaging catheter. An imaging core may be translatable and rotatable within the imaging catheter. The imaging core may include a first imaging device and a second imaging device different from the first imaging device. A connector assembly may be disposed adjacent to a proximal end region of the imaging catheter. The connector assembly may be configured to connect the imaging catheter to a control unit. The connector assembly may include a first connector for connecting the first imaging device to the control unit and a second connector for connecting the second imaging device to the control unit. The connector assembly may be spring-loaded.

摘要： A medical instrument system includes a control system and an operator input device coupled to an instrument including a sensor. The control system includes a processor and memory comprising instructions that cause the control system to: determine a distance between a distal tip of the instrument and an anatomical area based on sensor data; determine a motion scaling parameter based on the distance; receive an input instruction from the operator input device; map the input instruction to an output instruction including applying the motion scaling parameter to the input instruction to create the output instruction; instruct an actuator to move the instrument based on the output instruction; determine a second distance between the distal tip and the anatomical area based on the sensor data; determine a second motion scaling parameter based on the second distance; and stop movement of the instrument based on the second motion scaling parameter.

摘要： A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either within the brain. Once positioned at a desired location, the obturator is removed, leaving a distal end of the outer sheath adjacent an area of interest, and creating a working corridor. Interrogation of the area of interest may be performed to evaluate a disorder and/or abnormality, as well as evaluate treatment regimes. Interventional devices may also be introduced to the area of interest, as well as a variety of treatments.

摘要： A system for visualizing an anatomical target includes an imaging device (105) configured to collect real-time images of an anatomical target. A three-dimensional model (136) is generated from pre- or intra-operative images and includes images of structures below a surface of the anatomical target not visible in the images from the scope. An image processing module (148) is configured to generate an overlay (107) registered to the real-time images and to indicate the structures below the surface and a depth of the structures below the surface. A display device (118) is configured to concurrently display the real-time images and the overlay.

摘要： An ablation instrument (e.g., an ablation balloon catheter system) includes an elongate catheter having a housing with a window formed therein. An energy emitter is coupled to the elongate catheter and is configured to deliver ablative energy. A controller is received within the window and is coupled to the energy emitter such that axial movement of the controller within the window is translated to axial movement of the energy emitter and rotation of the controller within the window is translated into rotation of the energy emitter. The instrument includes a motor that is at least partially disposed within the housing of the catheter; a first gear that is operatively connected to and driven by the motor; and a second gear that is coupled to the energy emitter and is driven by the first gear to cause rotation of the energy emitter, while allowing the energy emitter to move axially.
