    • Method and system for inserting an implant, such as vaso-occlusive device, an embolic containment device, or a stent into a vascular space to a vascular site in a body utilizing a lumen-reducing catheter. The method and system can be used to treat aneurysm, tumors and other vascular malformations. A guide is inserted into the vascular space. First and second catheters are inserted into the vascular space along the guide. The first or delivery catheter defines a first cavity, and the second or lumen-reducing catheter defines a second, smaller cavity. The second catheter is inserted within the first catheter. In one embodiment, an implant is advanced together with the first and second catheters to a vascular site. In an alternative embodiment, after the first and second catheters are positioned, the guide and the second catheter are removed from the first cavity, and an implant is inserted through the first cavity. With these configurations, radial movement of the guide is restricted to the smaller, second cavity rather than the larger, first cavity.
    • 用于使用内腔减少导管将诸如血管闭塞装置,栓塞容纳装置或支架的植入物插入血管空间的体内的方法和系统。 该方法和系统可用于治疗动脉瘤,肿瘤和其他血管畸形。 导管插入血管空间。 第一和第二导管沿引导件插入血管空间。 第一或输送导管限定第一腔,并且第二或内腔减少导管限定第二较小的腔。 第二导管插入第一导管内。 在一个实施例中,植入物与第一和第二导管一起前进到血管部位。 在替代实施例中,在定位第一和第二导管之后,引导件和第二导管从第一腔体移除,并且植入物插入通过第一腔体。 利用这些构造,引导件的径向移动限于较小的第二腔而不是较大的第一空腔。

    • A medical lead and method of treating a patient are provided. The medical lead comprises an electrically insulative tubular membrane, a resilient spring element associated with the insulative membrane, and at least one electrode associated with the insulative membrane. The medical lead is configured to be collapsed into a compact form for percutaneous delivery into the patient, thereby obviating the need to perform an invasive surgical procedure on the patient. The body formed by these elements, when expanded, can be sized to fit within the epidural space of a patient. The patient can be treated by placing the medical lead into a collapsed state by applying a compressive force to the medical lead, percutaneously delivering the collapsed medical lead into the patient adjacent tissue to be treated, and placing the medical lead into an expanded state by releasing the compressive force. In one preferred method, the stimulation lead is used to stimulate tissue, such as spinal cord tissue.
    • 提供医疗用铅和治疗患者的方法。 医用引线包括电绝缘管状膜,与绝缘膜相关联的弹性弹簧元件以及与绝缘膜相关联的至少一个电极。 医疗用引线被构造成塌缩成紧密形式用于经皮输送到患者体内,从而避免了对患者执行侵入性外科手术的需要。 由这些元件形成的身体,当扩张时,其尺寸可以适合于患者的硬膜外腔内。 可以通过向医用引线施加压缩力将医用引线置于折叠状态来将患者放置在患者身体中,将经塌陷的医用导管经皮递送到邻近被治疗组织的患者中,并通过释放将医用引线放入扩张状态 压缩力。 在一种优选的方法中,刺激引线用于刺激组织,例如脊髓组织。

    • A medical lead and method of treating a patient are provided. The medical lead comprises an electrically insulative tubular membrane, a resilient spring element associated with the insulative membrane, and at least one electrode associated with the insulative membrane. In the preferred embodiment, the tubular membrane has a non-circular cross-sectional shape. The spring layer is configured to urge that insulative membrane into an expanded geometry.
