Beschreibung
Zusammenfassung:	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.
