摘要： A composite guidewire comprising a proximal wire segment having a proximal end, a distal end and a longitudinal axis extending therebetween, the distal end being formed with a first flat planar bonding face which extends parallel to the longitudinal axis, the proximal wire segment having a first elasticity; a distal wire segment having a proximal end, a distal end and a longitudinal axis extending therebetween, the proximal end being formed with a second flat planar bonding face which extends parallel to the longitudinal axis, the distal wire segment having a second elasticity; wherein the first and second flat planar bonding faces of the proximal wire segment are formed complementary to one another; and further wherein the proximal and distal wire segments are joined together by bonding the first flat planar bonding face to the second flat planar bonding face in an overlapping manner and a method for forming a composite guidewire.

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.
摘要翻译：温度控制致动器具有带近端和可移动远端部分的壳体（12）。芯线（16）沿着壳体延伸，其远端部分锚定到壳体的远端部分。芯线的远端部分具有奥氏体状态和马氏体状态。远端部分响应于沿着芯线的测温部分（22,24）的温度变化而在奥氏体和马氏体状态之间转变来移动远端部分。与芯线的远端部分机械连通的近侧部分将由张紧元件（20）提供的张力传递到远端部分。联接到芯线的近侧部分的张紧元件不断地向芯线施加张紧力。
