摘要： Stent delivery systems and methods for making and using stent delivery systems are disclosed. An example stent delivery system may include a guide member having a proximal portion and a distal portion. A stent may be disposed about the distal portion of the guide member. The stent may have a wall having an opening formed therein. A pusher member may be disposed about the guide member and positioned proximal of the stent. A holding filament may be disposed at the opening and may extend to the proximal portion of the guide member. The holding filament may be configured to releasably secure the position of the stent relative to the pusher member. The holding filament may be releasable from the stent independently of movement of the guide member.

摘要： A medical instrument such as a guidewire that is designed to have controlled torque transmission along its length. Specially treated areas are placed in selected and equal areas along the entire length of the elongated shaft of the medical instrument, and are separated from one another by untreated areas. This process ensures that any torque is transmitted distally, in a smooth manner, regardless of the guidewire position, thus resulting in a substantial reduction in whipping. In one embodiment, a stainless steel guidewire is utilized, and is subjected to annealing heat treatment in selected areas. This annealing process creates a mandrel that has repeated temper properties along its length. Torque applied at one end of this mandrel is transmitted to the opposite end in an even and controlled manner, even when the mandrel is formed into a loop.
摘要翻译： 一种医疗器械，例如导丝，其设计成沿其长度具有受控的扭矩传递。 特殊处理区域沿着医疗器械的细长轴的整个长度放置在选定的和相等的区域中，并且通过未处理的区域彼此分离。 该过程确保任何扭矩以平滑的方式向远侧传递，而不管导丝位置如何，从而导致鞭打的显着减少。 在一个实施例中，使用不锈钢导丝，并在选定的区域进行退火热处理。 该退火工艺产生了沿其长度具有反复回火特性的心轴。 即使当心轴形成环时，施加在该心轴的一端的扭矩以均匀和受控的方式传递到相对端。

摘要： Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a dual function medical device. The dual function medical device may include an inner guidewire. An outer guidewire may be disposed about the inner guidewire. The outer guidewire may include a tubular member having a plurality of slots formed therein. A torque member may be coupled to the dual function medical device. The torque member may be configured to independently attach to the inner guidewire and the outer guidewire.

摘要： An apparatus for deployment of multiple hemostatic clips, comprises a shaft connected to a handle and a control linkage operatively connected to the handle in combination with a magazine disposed at a distal end of the shaft, the magazine containing a plurality of clips arranged in a chain rotatable within the magazine, wherein a proximal-most one of the clips is coupled to the control linkage, a distal portion of the magazine being contoured to permit opening of a distal-most one of the clips during a distal stroke of the control linkage, and to assist closing and locking of the distal-most clip during a proximal stroke of the control linkage, the magazine including an expanded chamber sized to allow opening in any rotational orientation of a next clip located immediately proximal to the distal-most clip to a degree sufficient to disengage the distal-most clip. A method for deploying multiple hemostatic clips, comprises positioning a distal end of a magazine containing a clip chain over selected target tissue and actuating a control link of the magazine in a distal stroke to open and distally translate a distal-most clip of the clip chain in combination with orienting the open distal-most clip in a desired orientation to grasp the target tissue and actuating the control link in a proximal stroke to close and lock the distal-most clip over the target tissue. The control link is further actuated in the proximal stroke to move a next clip immediately proximal to the distal-most clip into an expanded portion of the magazine sized to allow the next clip to open to a degree sufficient to release the distal-most clip regardless of a circumferential orientation of the next clip.

摘要： A deflecting method and deflecting apparatus allows the distal end of device, for example an endoscopic medical device, to be remotely and adjustably deflected from a straight configuration to a deflected configuration. Manipulating a proximal handle causes the deflection, controls actuation of an end effector assembly on the distal end, and straightens the deflecting apparatus back to its original configuration.

摘要： A drainage stent delivery system including an elongate shaft of a medial device, a drainage catheter or stent, and an interference fit member for selectively coupling the drainage stent to the elongate shaft. The drainage stent is selectively coupled to a distal portion of the elongate shaft by an interference fit between the interference fit member and the drainage stent such that axial movement of the elongate shaft relative to the drainage stent moves the interference fit member from a first position in which the interference fit member is engaged with the drainage stent and forms an interference fit with the drainage stent to a second position in which the interference fit member is disengaged from the drainage stent.
