A robotic catheter procedure system includes a bedside system and a workstation. The bedside system includes an actuating mechanism configured to engage and to impart movement to a percutaneous device. The workstation includes a user interface and a control system configured to be operatively coupled to the user interface, the bedside system, and a medical imaging system. The control system is responsive to a first input and to a second input, and the user interface receives the second input from a user. The control system is configured to generate a first control signal to the medical imaging system based on the first input, and the medical imaging system captures at least one image in response to the first control signal. The control system is configured to generate a second control signal to the actuating mechanism based on the second input, and the actuating mechanism causes movement of the percutaneous device in response to the second control signal. The first input is indicative of upcoming percutaneous device movement.

The disclosed invention provides a transseptal insertion device which is suitable for facilitating precise and safe transseptal puncture of a cardiac interatrial septum. The transseptal insertion device includes a sheath that defines at least one lumen therein, one or more positioning balloons that are connected to a distal end of the sheath, a puncture member movably positioned within the at least one lumen, and a puncture member balloon located on the puncture member. The sheath has one or more deflation ports to deflate the one or more positioning balloons. The puncture member balloon, when inflated, is capable of sealing the one or more deflation ports in the sheath, permitting the inflation of the one or more positioning balloons. When the puncture member moves toward fossa ovalis, the inflated puncture member balloon moves away from the deflation ports, allowing the positioning balloons to be deflated.

A non-transitory computer-readable medium (CRM) storing computer program code executed by a computer processor that executes a process, an information processing apparatus, and a model generation method that outputs complication information for a medical treatment. The process includes acquiring a medical image obtained by imaging a lumen organ of a patient before treatment, inputting the acquired medical image into a trained model so as to output complication information on a complication that is likely to occur after the treatment when the medical image is received, and outputting the complication information. Preferably, complication information including a type of the complication that is likely to occur and a probability value indicating an occurrence probability of the complication of the type is output.

Improvements to devices, systems, and methods for delivering and/or deploying an implantable medical device are described. An implantable medical device may include an annuloplasty ring for implantation on a valve of a patient. Systems and methods may be configured to present graphical user interfaces with device images to implement efficient and accurate implantation of the implantable medical device. The device images may be based on sensor information obtained via sensors associated with the implantable medical device, such as a camera device, a diagnostic imaging device, position sensors, and/or the like. In other aspects, systems and methods may determine optimized configurations for the implantable medical device based on device characteristics including, without limitation, a shape formed by components of the implantable medical device and/or component coordinate information. Systems and methods may operate to facilitate deployment of the implantable medical device to correspond with the optimized configuration. Other embodiments are described.

An ultrasonic probe of an embodiment includes a head part. The head part includes a plurality of ultrasonic elements that output ultrasonic waves and receive reflected waves of the output ultrasonic waves. The head part is provided with a through hole for guiding a puncture needle and a slit for guiding the puncture needle to the through hole.

Systems and methods are disclosed for identifying anatomically relevant blood flow characteristics in a patient. One method includes: receiving, in an electronic storage medium, a patient-specific representation of at least a portion of vasculature of the patient having a lesion at one or more points; receiving values for one or more metrics of interest associated with one or more locations in the vasculature of the patient; receiving one or more observed lumen measurements of the vasculature of the patient; determining the location of a diseased region in the vasculature of the patient using the received values for the one or more metrics of interest, wherein the determination of the location includes predicting or receiving one or more healthy lumen measurements of the vasculature of the patient; determining the extent of the diseased region; and generating a visualization of at least the diseased region.

Devices, systems, and methods are provided for image-guided interventional procedures and other uses. Nested articulated catheter shaft systems may have an imaging catheter with an ultrasound transducer supported by a fluid-driven articulated sheath portion. Drive fluid can be transmitted distally along an asymmetric sheath via eccentric passages to an articulated portion of the imaging catheter distal of a port. An articulated shaft supporting a therapeutic tool can be advanced within a working lumen of the imaging sheath to the port so that the tool is within a field of view of the transducer. The fluid transmission channels may take much less cross-sectional area of the sheath than a mechanical pull-wire system, allowing the nested sheath/shaft system to provide safer access to a chamber of the heart and to facilitate precise independent control over 3D ultrasound imaging and image-guided structural heart therapies or the like.

A system for tracking an instrument with ultrasound includes a probe (122) for transmitting and receiving ultrasonic energy and a transducer (130) associated with the probe and configured to move with the probe during use. A medical instrument (102) includes a sensor (120) configured to respond to the ultrasonic energy received from the probe. A control module (124) is stored in memory and configured to interpret the ultrasonic energy received from the probe and the sensor to determine a three dimensional location of the medical instrument and to inject a signal to the probe from the transducer to highlight a position of the sensor in an image.

An ultrasound device (10) includes a probe (12) including a tube (14) sized for insertion into a patient and an ultrasound transducer (18) disposed at a distal end (16) of the tube. A camera (20) is mounted at the distal end of the tube in a fixed spatial relationship to the ultrasound transducer. At least one electronic processor (28) is programmed to: control the ultrasound transducer and the camera to acquire ultrasound images (19) and camera images (21) respectively while the ultrasound transducer is disposed in vivo inside the patient; and construct a keyframe (36) representative of an in vivo position of the ultrasound transducer including at least ultrasound image features (38) extracted from at least one of the ultrasound images acquired at the in vivo position of the ultrasound transducer and camera image features (40) extracted from one of the camera images acquired at the in vivo position of the ultrasound transducer.

A handle apparatus comprising detachable hardware and void regions or attachment devices that accommodate the shape of surgical devices and imaging units such that the device is held securely and mechanically fixed to the imaging unit within the handle assembly.
