  • Publication number: 20070142749
    Abstract: In a preferred embodiment, medical apparatus comprising a catheter (12) which operable to be inserted into a human subject (10) is disclosed herein. Haptic sensors (22, 24) and deformation sensors (26, 27) are connected to the catheter (12) and these are disposed at a plurality of locations along the length of the catheter (12). The haptic sensors measures 3D forces (18) acting on the catheter (12) at the disposed locations and these forces are provided to a haptic feedback device (14) which provides haptic feedback to, an interventional radiologist. The deformation sensors (26, 27) on the other hand, measures the deformation of the catheter (12) at the disposed locations and this information determines the shape of the catheter (12) which is represented on a display (16) for viewing by the radiologist.

  • Publication number: 20040214313
    Abstract: The present invention relates to a novel cell co-culture system and methods of using the same for studying cellular interactions. The co-culture system comprises a cell culture container partitioned into multiple compartments by removable partition units/separating walls. Different cell types or materials can be placed and cultured in the various compartments. When the cells are ready for cell interaction studies, the removable walls separating two adjacent compartments are removed and cellular interaction can then be studied in a defined area, i.e. the area previously occupied by the bottom edges of the removable walls. The present invention thus provides a cell co-culture system that would set up a new and flexible platform for most cell interaction studies.

  • Publication number: 20020168618
    Abstract: This invention provides a system and method for computer simulation of image-guided diagnostic and therapeutic procedures such as vascular catheterization, angioplasty, stent, coil and graft placement, embolotherapy and drug infusion therapy. In a particularly preferred aspect, the system is configured to resemble a cardiovascular catheterization laboratory where interventional radiology procedures are performed. A first user can interactively manipulate therapeutic catheters, guidewires and other medical devices in real-time while viewing patient-specific medical image data sets in a manner similar to that encountered in a clinical procedure.
