Abstract: The invention relates to assisting a user in moving an insertion element within an object. A three-dimensional (3D) position and 3D local shape of the insertion element are tracked within the object. Based on the tracked 3D position and 3D local shape of the insertion element, an insertion element representation (42''') representing the insertion element within the object in its 3D position and 3D local shape is generated. Furthermore at least two different markings (78) applied along the length of the insertion element representation (42''') representing indications of the local shape of the insertion element are provided. A display image (60") including the insertion element representation (42''') with the different markings (78) is displayed. Markings can for example include alternating ring- like structures (78) with alternating lighter and darker colors and/or different colors for the tip and the rest of the insertion element representation for improving 3D visualization of insertion elements.

Abstract: A thrombectomy device (10) includes a retrieval device (12) configured to deploy and subsequently retrieve an associated tethered self-expanding stent (2), the retrieval device including a guidewire (14) having a tip (13) that is radiopaque. At least one electronic processor (20) is programmed to: receive a time sequence of images (35) of extension of the guidewire through a clot during a thrombectomy procedure being performed using the thrombectomy device; determine a geometric change of the tip of the guidewire; identify a completion of the extension of the guidewire through the clot based on the geometric change of the tip of the guidewire; and respond to the identification of the completion of the extension of the guidewire through the clot by: outputting an indication (36) that the guidewire is extended completely through the clot; and/or controlling a robot (16) to stop the extension of the guidewire through the clot.

Abstract: Devices, systems, and methods for evaluating a physiological condition of a vessel are disclosed. In an embodiment, a medical system is disclosed. One embodiment of the medical system comprises a medical processing unit in communication with a first sensor, a second sensor, and an imaging source configured to obtain images of at least one intravascular instrument positioned within a body lumen. The medical processing unit is configured to: receive the images obtained by the imaging source; detect, using the images, when the first sensor is in a pre-determined spatial configuration with respect to the second sensor; and automatically initiate normalization of the first sensor and the second sensor in response to detecting that the first sensor is in the pre-determined spatial configuration with respect to the second sensor.
