20090088830 | SYSTEM AND METHOD FOR INTRAOPERATIVE GUIDANCE OF STENT PLACEMENT DURING ENDOVASCULAR INTERVENTIONS - A method for guiding stent deployment during an endovascular procedure includes providing a virtual stent model of a real stent that specifies a length, diameter, shape, and placement of the real stent. The method further includes projecting the virtual stent model onto a 2-dimensional (2D) DSA image of a target lesion, manipulating a stent deployment mechanism to navigate the stent to the target lesion while simultaneously acquiring real-time 2D fluoroscopic images of the stent navigation, and overlaying each fluoroscopic image on the 2D DSA image having the projected virtual stent model image, where the 2D fluoroscopic images are acquired from a C-arm mounted X-ray apparatus, and updating the projection of the virtual stent model onto the fluoroscopic images whenever a new fluoroscopic image is acquired or whenever the C-arm is moved, where the stent is aligned with the virtual stent model by aligning stent end markers with virtual end markers. | 2009-04-02 |
20090088831 | STENT AND STENT DELIVERY DEVICE - An stent includes an outer stent base layer formed from a metallic material, an inner stent base layer formed from a metallic material and positioned inside the outer stent base layer, and a resinous adhesive layer containing a biodegradable polymer which is placed between the outer stent base layer and the inner stent base layer, and bonds together the outer stent base layer and the inner stent base layer. The resinous adhesive layer contains a biodegradable polymer containing a physiologically active substance in such a manner as to permit it to release itself. | 2009-04-02 |
