    摘要： The methods and reagents described in this invention are used to analyze circulating tumor cells, clusters, fragments, and debris. Analysis is performed with a number of platforms, including flow cytometry and the CellSpotter® fluorescent microscopy imaging system. Analyzing damaged cells has shown to be important. However, there are two sources of damage: in vivo and in vitro. Damage in vivo occurs by apoptosis, necrosis, or immune response. Damage in vitro occurs during sample acquisition, handling, transport, processing, or analysis. It is therefore desirable to confine, reduce, eliminate, or at least qualify in vitro damage to prevent it from interfering in analysis. Described herein are methods to diagnose, monitor, and screen disease based on circulating rare cells, including malignancy as determined by CTC, clusters, fragments, and debris. Also provided are kits for assaying biological specimens using these methods.

    摘要： A tubular transition member having an annular wall with at least one cut extending through the annular wall is disclosed for controlling a transition in stiffness of a catheter from a stiffer more pushable proximal section to a more flexible and trackable distal section and increasing kink resistance. The transition member may extend across the junction formed between the stiffer proximal section and the more flexible distal section. The transition member may be used in conjunction with any type of catheter including single-operator-exchange type catheters, over-the wire type catheters, and/or fixed-wire type catheters.

    摘要： The invention relates to a method for real-time determination an optimal corrected surface of a first bone and/or a second bone forming together an articulation, the first and/or second bones presenting an overgrowth deformation, said corrected surface providing a greater range of motion of the articulation, the method comprising the following steps: i) constructing from acquired images of the articulation 3D voxel models of the first bone and the second bone; ii) for each of first and second bone voxel models, constructing a coordinate system defmed by a center and three axes; iii) applying a motion pattern on the coordinate system of the second bone with respect to the coordinate system of the first bone, a motion pattern being a set of contiguous positions of the first or second bone coordinate systems with respect to the other bone coordinate system, the contiguous positions defining a movement of one bone with respect to the other, wherein said motion pattern is initially loaded from a data base of pre-defined motion patterns; iv) determining a resection volume from said motion pattern as being the union of interpenetration volumes of the first or second bone voxel model with the other bone voxel model for each position of the motion pattern; v) determining the optimal corrected surface by virtually removing said resection volume from the first and/or the second bone voxel model.
