Patent attributes
A medical device can include an elongate manipulation member, and a thrombectomy device connected to the elongate manipulation member. The thrombectomy device can have a first configuration and a second configuration, the thrombectomy device being expandable from the first configuration to the second configuration. The thrombectomy device can include an arcuate marker-mounting projection attached to a portion of the thrombectomy device configured to contact a thrombus. A marker can be coupled to, and extending around, the arcuate marker-mounting projection with the marker and the arcuate marker-mounting projection contacting each other at three discrete locations. A method for engaging a thrombus can include advancing a thrombectomy device to a location radially adjacent to a thrombus in a blood vessel. The thrombectomy device can be positioned such that a marker, disposed at a proximal end of a working length of thrombectomy device, is proximal to or longitudinally aligned with a proximal end of the thrombus, and can be expanded into the thrombus.
