| 20080287795 | System And Method For Identifying A Vascular Border - A system and method is provided for using a first vascular image, or more particularly a plurality of control points located thereon, to identify a border on a second vascular image. Embodiments of the present invention operate in accordance with an intra-vascular ultrasound (IVUS) device and a computing device electrically connected thereto. Specifically, in one embodiment of the present invention, an-IVUS console is electrically connected to a computing device and adapted to acquire IVUS data. The IVUS data (or multiple sets thereof) is then provided to (or acquired by) the computing device. In one embodiment of the present invention, the computing device includes a plurality of applications operating thereon—i.e., a border-detection application, an extrapolation application, and an active-contour application. These applications are used to (i) identify a border and control points on a first IVUS image (i.e., any IVUS image), (ii) extrapolate the control points to a second IVUS image (i.e., another IVUS image), (iii) identify a border on the second IVUS image, and (iv) adjust the border on the second IVUS image in accordance with at least one factor. In one embodiment of the present invention, the at least one factor is selected from a group consisting of gradient factor, continuity factor, and curvature factor. | 11-20-2008 |
| 20110087101 | System and Method for Determining a Transfer Function - A system and method is provided for using ultrasound data backscattered from vascular tissue to estimate the transfer function of a catheter (including components attached thereto—e.g., IVUS console, transducer, etc.). Specifically, in accordance with a first embodiment of the present invention, a computing device is electrically connected to a catheter and used to acquire RF backscattered data from a vascular structure (e.g., a blood vessel, etc.). The backscattered ultrasound data is then used, together with an algorithm, to estimate the transfer function. The transfer function can then be used (at least in a preferred embodiment) to calculate response data for the vascular tissue (i.e., the tissue component of the backscattered ultrasound data). In a second embodiment of the present invention, an IVUS console is electrically connected to a catheter and a computing device and is used to acquire RF backscattered data from a vascular structure. The backscattered data is then transmitted to the computing device, where it is used to estimate the catheter's transfer function and to calculate response data for the vascular tissue. The response data and histology data are then used to characterize at least a portion of the vascular tissue (e.g., identify tissue type, etc.). | 04-14-2011 |

| 20080223541 | COMPLIANT FILL TUBE ASSEMBLY, FILL TUBE THEREFOR AND METHOD OF USE - A fill tube assembly is for a casting mold. The fill tube assembly includes a fill tube having a tubular member with a receiving end, a mold-engaging end and an intermediate portion. The mold-engaging end has a tapered flange radially extending therefrom, the remainder of the tubular member has a substantially uniform cross-section. A clamping assembly is structured to maintain a substantially leakproof seal at the fill tube, casting mold interface while accommodating dimensional variations. The clamping assembly includes a gasket, a load ring, a clamping plate and a pre-load gap between the clamping plate and the casting mold and optionally includes a dimensional compensating ring. When tightened, the clamping plate biases the load ring against the flange thereby distributing a uniform load against the casting mold, compressing the gasket therebetween while narrowing the pre-load gap to accommodate dimensional variations. A method of use is also disclosed. | 09-18-2008 |
