    摘要: Formulations of shape memory polymer (SMP) are integrated with several existing clinically available medical fabrics. The SMP portion of a SMP-integrated fabric can be fabricated in varying thicknesses with the minimum thickness determined by the thickness of the underlying fabric and up to almost any thickness. A large variety of patterns may be formed in SMP-integrated fabrics based upon how the shape memory polymer is integrated into the base fabric. Integration of the SMP with the base fabrics does not alter the shape memory functionality of the SMP. The design tools for controlling activation rate for traditional SMP materials thus apply to SMP-integrated fabrics. SMP-integrated fabrics may also be steam sterilized without loss of shape memory functionality. By using multiple formulations of SMP on a single piece of fabric, a large combination of material properties may be provided within a single SMP-integrated fabric device.

    摘要: A shape memory coiling device (5) for occluding a vessel or other vascular target includes a shape memory polymer material. The shape memory material is formed in a formation state as a plurality of coiled members (10) and then constrained in a pre-deployed state as a plurality of elongate members (10) configured for delivery through a delivery device wherein the plurality of elongate members (10) are aligned axially with respect to each other and the delivery device (20). The shape memory material may be formed in an intra-deployed state such that at least one of the plurality of elongate members (10) will anchor the device (5) before filling the vascular target and becoming a coiled member. The shape memory material is formed in a deployed state as a plurality of coiled members (10). In some embodiments, the vascular target is an aneurysm.

    摘要: An Echo PIV analysis process, apparatus and algorithm are developed to reduce noise and analyze DICOM images representing a fluid flow of a plurality of particles. A plurality of DICOM images representing sequential image pairs of a plurality of particles is received. The plurality of DICOM sequential image pairs are grouped. The sequential image pairs are correlated to create N cross correlation maps. An average cross-correlation transformation is applied to each cross correlation map to create an image pair vector map for each image pair. A maximizing operation is applied to one or more of the N adjacent image pair vector maps to create a modified image pair vector map for the one or more of the N image pairs. The maps are combined to create a corresponding temporary vector map that are averaged to obtain a mean velocity vector field of the sequential image pairs.
