    摘要： A complex coil configured such that in a relaxed, minimum energy state configuration loops are formed having various orientations relative to each other. The complex coil provide improved thrombus formation and reduced rotation or tumbling once implanted. The complex coil is formed of a material that may be deformed for purposes of placing the complex coil into a catheter and returns to a complex shape that includes said loops once deployed.

    摘要： An implantable embolic device having a stretch-resistant member passing therethrough that also serves as a tether for connecting the device to a delivery system. The stretch-resistant member is attached at a proximal and distal end of the device and extends proximally to the delivery device. The proximal attachment point serves to isolate a distal, stretch resisting segment of the member from axial tension placed on a proximal, connecting section of the member. Thus, the portion of the stretch-resistant member being used to connect the embolic device to a delivery device may be placed under tension without placing tension or distorting the implant.

    摘要翻译： 一种具有穿过其中的抗拉构件的可植入栓塞装置，其也用作将装置连接到输送系统的系绳。 抗拉构件附接在装置的近端和远端，并向近端延伸到输送装置。 近端连接点用于将构件的远端，抗拉伸部分与放置在构件的近端连接部分上的轴向张力隔离。 因此，用于将栓塞装置连接到输送装置的抗拉构件的部分可以被放置在张力下而不会造成植入物的张力或扭曲。

    摘要： A microcatheter comprises a coil formed over an inner liner. The coil is covered with a series of outer jacket segments that decrease in durometer relative to proximally adjacent segments. Preferably, these segments have angled ends that allow each segment to be inserted and bonded into the segment prior to it. The outer jacket ultimately terminates at a distal of the microcatheter with the segment having the lowest durometer.

    摘要： In one preferred embodiment, a prosthesis is provided that can be selectively expanded by increasing the temperature of the prosthesis within the patient. The prosthesis is composed of a shape memory material that expands when heated to a temperature greater than an average body temperature, allowing the user to selectively heat and therefore expand the prosthesis at a desired location.
