摘要： A temperature-controlled actuator has a housing (12) with a proximal end and a moveable distal portion. A core-wire (16) extends along the housing, with its distal section anchored to the distal portion of the housing. The core-wire's distal section has an austenite state and a martensite state. The distal section moves the distal portion by transitioning between the austenite and martensite states in response to a temperature change along a thermometric section (22, 24) of the core-wire. A proximal section in mechanical communication with the core-wire's distal section transmits tension, provided by a tensioning element (20), to the distal section. The tensioning element, which is coupled to the proximal section of the core-wire, constantly applies a tensioning force to the core-wire.

摘要： 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 (38) having a compressed state, in which it defines a first path relative to the axis. A corewire (26) 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 (38) and attached to the core-wire (26) causes the flexible distal section (38) to follow the same path. An actuator engaged to a proximal end (36) of the core-wire (26) enables selective application of a tensile force thereto. This tensile force causes the core-wire (26) and the flexible distal section (38) to transition together between the first path and the second path.
