    Abstract: Devices, methods, and kits for removing material from a body lumen. The devices and methods may be used in a variety of body lumens, including but not limited to coronary arteries and other blood vessels. In general, the device or catheter has a scoop-shaped cutting blade mounted on a catheter body for removing material from a body lumen. The cutting blade has a cutting edge that travels a curved path about a pivot point of the blade, preferably moving in an outward direction from the catheter body to engage the target material for removal. The scoop-shaped blade has a collection surface located behind the cutting edge to collect material removed from said body lumen. Advantageously, a scoop-shaped cutting blade according to the present invention facilitates material engagement and the collection surface may be used to bring material back into the catheter body as the blade begins to part-off material. The cutting blade is usually mounted to move in an inward direction towards the catheter body after the cutting edge has engaged the material. The cutting blade can also more easily engage occlusive material that is compressed against the body lumen wall.

    Abstract translation: 用于从体腔去除材料的装置，方法和试剂盒。 装置和方法可以用于各种体腔，包括但不限于冠状动脉和其他血管。 通常，装置或导管具有安装在导管主体上的勺形切割刀片，用于从体腔去除材料。 切割刀片具有围绕叶片的枢转点行进弯曲路径的切割边缘，优选地从导管主体沿向外的方向移动以接合目标材料以便移除。 勺形刀片具有位于切割边缘后面的收集表面，以收集从所述体腔移除的材料。 有利地，根据本发明的勺形切割刀片有助于材料接合，并且收集表面可以用于当刀片开始分离材料时将材料返回到导管主体中。 切割刀片通常安装成在切削刃已经接合材料之后沿向内的方向朝向导管主体移动。 切割刀片还可以更容易地接合被压靠在体腔壁上的封闭材料。

    Abstract: A verification system which can be used over electronic networks, such as the Internet, to help prevent phishing, electronic identity theft, and similar illicit activities, by verifying the authenticity of electronic entities (for example, websites). Users and electronic entities register with an authenticating entity. The authenticating entity shares an encryption method with registered electronic entities and establishes a secret code for each registered electronic entity. The secret code is combined with other information and encrypted before being transmitted over the network to ensure that the secret code cannot be compromised. Also disclosed are systems for virtual token devices, which provided object-based authentication without a physical device. Also disclosed are dynamic media credentials, which display nearly-unique behavior, previously specified and known to a user, to assist in verifying the authenticity of the presenter.
