Abstract: Systems and methods for determining one or more phases of anatomical movement are provided. A catheter positioned in an anatomical element may be tracked using a tracker configured to track a pose of the catheter. Sensor data corresponding to a plurality of pose information of the catheter may be received from the tracker. One or more phases of motion of the anatomical element may be determined based on the plurality of pose information. An image may be received at a target phase of the one or more phases.

Abstract: Systems and methods for correlating one or more motions of an anatomical element are provided. A plurality of first pose information of a first tracker corresponding to pose information of the first tracker can be received over a period of time. One or more first motion phases of a first motion of an anatomical element can be determined based on the plurality of first pose information. A plurality of second pose information of a second tracker corresponding to pose information of the second tracker can be received over the period of time. One or more second motion phases of a second motion of the anatomical element can be determined based on the plurality of second pose information.

Abstract: A method of calibrating an ultrasound imaging system including: capturing ultrasound image data including a first tissue and a second tissue through which ultrasound waves travel at different speeds, the ultrasound image data captured based on a predetermined single speed of ultrasound waves through both the first tissue and the second tissue being the same; segmenting the first tissue and the second tissue in a sonogram based on the image data; identifying a first depth of the first tissue and a second depth of the second tissue based on the sonogram; identifying an actual first speed of ultrasound waves through the first tissue and an actual second speed of ultrasound waves through the second tissue; and generating a calibrated image that accounts for ultrasound waves through the first tissue at the first actual speed that is different than the second actual speed of the ultrasound waves through the second tissue.

Abstract: A system and method to provide output regarding an imaging system. The output includes, in various embodiments, a display illustrating portions features and portions selected by a user. The imaging system may include a user moveable and/or holdable imaging system.

Abstract: An implant tool system includes an implantable medical lead and a delivery catheter. The implantable medical lead is configured to be delivered through an access point on a body of a patient. The delivery catheter is configured to deliver the implantable medical lead along an implantation path in the body of the patient. A visual marker is positioned on a body of the implantable medical lead. The visual marker is positioned proximal a distal end of the implantable medical lead by a distance indicative of a length of lead to introduce into the body of the patient. The visual marker may be positioned such that introduction of the length of lead into the body of the patient provides lead slack that reduces the likelihood of one or more of dislodgment of the implantable medical lead from the implant point or damage to a tissue of the patient.

Abstract: A catheter for delivery of a leadless pacemaker includes an elongate flexible tubular body with a distal end including a delivery cup configured to releasably retain a pacing capsule of the leadless pacemaker. The delivery cup includes an echogenic structure.

Abstract: A medical device having an echogenic region facilitate guiding the medical device to a selected location within a patient using ultrasound. The medical device includes a first layer having a first polymer. The first layer defines an elongate body extending along a longitudinal axis from a proximal end to a distal end and defines a lumen extending longitudinally within the elongate body. The medical device further includes a second layer having a second polymer. The second layer is disposed on and radially adjacent to the first layer and defines the echogenic region. The echogenic region includes the second polymer and an echogenic metallic or ceramic material dispersed in the second polymer. The echogenic region is detectable using ultrasound imaging.

Abstract: A transnasal transesophageal balloon catheter includes at least one compliant balloon attached to the external surface of the tubular body. An arrangement of structures extend away from the internal surface of the tubular body, and exposed probe guide surfaces on the structures form a lumen with a diameter of less than about 15 French (Fr) (5 mm) extending from the proximal end to the distal end of the tubular body and configured to slidably and rotatably receive the ultrasound probe. An arrangement of elongate fluid channels are interspersed with the structures. The fluid channels are in fluid communication with the lumen and transport a fluid between a fluid ingress port and a fluid egress port to at least partially inflate or deflate the balloon.
