摘要： A catheter which includes a cutting element having one or more raised elements is provided. The cutting element has a cup-shaped surface at the distal end that may be smooth and continuous except for the raised elements. The raised elements have a surface that tends to direct cut particles of material towards one or more of the axis of rotation of the cutting element, the catheter axis, or a particle collection chamber. In further aspects of the invention, a cutting element oscillates in a direction roughly parallel to the axis of rotation of the cutting element.

摘要： A method is provided for predicting material properties and creating or modifying materials to exhibit desired properties. Materials and devices are described that are formed using the methods. Using embodiments described above, a number of advantages are realized. One advantage includes an ability to predict hysteresis in a multiple phase material. One embodiment includes an ability to modify or create a material to exhibit low hysteresis. Using embodiments described above to predict material properties and modify material properties, a number of materials can be created. An improved shape memory alloy with low hysteresis can be created. Additionally, a material that exhibits any of a number of properties that are normally mutually exclusive can be created.
