Abstract

An instrument for removal of an object, e.g., a blood clot lodged in a blood vessel, has a longitudinally extending support that defines an axis. The support has a flexible distal section and a rigid proximal section. The flexible distal section has a compressed state, in which it defines a first path relative to the axis. A core-wire extending along the axis has a relaxed state in which it defines a second path relative to the axis. An anchor disposed on the flexible distal section and attached to the core-wire causes the flexible distal section to follow the same path. An actuator engaged to a proximal end of the core-wire enables a surgeon to selectively apply a tensile force thereto. This tensile force causes the core-wire and the flexible distal section to transition together between the first path and the second path.
