Devices, systems and methods are provided for tissue approximation and repair at treatment sites. In particular, fixation devices are provided comprising a pair of elements each having a first end, a free end opposite the first end, and an engagement surface therebetween for engaging the tissue, the first ends being moveable between an open position wherein the free ends are spaced apart and a closed position wherein the free ends are closer together with the engagement surfaces generally facing each other. The fixation devices also include a locking mechanism coupled to the elements for locking the elements in place. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site.

A system for imaging and providing therapy to one or more regions of interest is presented. The system includes an imaging and therapy catheter configured to image an anatomical region to facilitate assessing need for therapy in one or more regions within the anatomical region and delivering therapy to the one or more regions of interest within the anatomical region. The catheter includes a therapy device having a plurality of independently controllable therapy elements. The independence of the therapy elements is exploited when multiple regions are to receive therapy simultaneously or at a given catheter position within a subject.

An imaging and interventional system and methods are provided. The system comprises an imaging device for acquiring volumetric image data for an anatomical region of interest, a catheter for acquiring electrophysiological (EP) measurements of the anatomical region of interest, the catheter having at least one tracking coil for detecting signals indicative of a position of the catheter, and, a processor coupled to the catheter for receiving the EP measurements and signals indicative of the position of the catheter. The position of the catheter and EP measurements are combined and superimposed on a resultant image. The method comprises acquiring volumetric image data for an anatomical region of interest, acquiring position data for a catheter inserted in the region of interest, obtaining electrophysiological (EP) measurements for the region of interest and combining the image data, position data and EP measurements into a resultant image for use in the interventional procedure.

A system for imaging and providing therapy to one or more regions of interest is presented. The system includes an imaging and therapy catheter configured to image an anatomical region to facilitate assessing need for therapy in one or more regions within the anatomical region and delivering therapy to the one or more regions of interest within the anatomical region. In addition, the system includes a medical imaging system operationally coupled to the catheter and having a display area and a user interface area, wherein the medical imaging system is configured to facilitate defining a therapy pathway to facilitate delivering therapy to the one or more regions of interest.

The present invention relates to minimally invasive X-ray guided interventions, in particular to an image processing and rendering system and a method for improving visibility and supporting automatic detection and tracking of interventional tools that are used in electrophysiological procedures. According to the invention, this is accomplished by calculating differences between 2D projected image data of a preoperatively acquired 3D voxel volume showing a specific anatomical region of interest or a pathological abnormality (e.g. an intracranial arterial stenosis, an aneurysm of a cerebral, pulmonary or coronary artery branch, a gastric carcinoma or sarcoma, etc.) in a tissue of a patient's body and intraoperatively recorded 2D fluoroscopic images showing the aforementioned objects in the interior of said patient's body, wherein said 3D voxel volume has been generated in the scope of a computed tomography, magnet resonance imaging or 3D rotational angiography based image acquisition procedure and said 2D fluoroscopic images have been co-registered with the 2D projected image data. After registration of the projected 3D data with each of said X-ray images, comparison of the 2D projected image data with the 2D fluoroscopic images - based on the resulting difference images - allows removing common patterns and thus enhancing the visibility of interventional instruments which are inserted into a pathological tissue region, a blood vessel segment or any other region of interest in the interior of the patient's body. Automatic image processing methods to detect and track those instruments are also made easier and more robust by this invention. Once the 2D-3D registration is completed for a given view, all the changes in the system geometry of an X-ray system used for generating said fluoroscopic images can be applied to a registration matrix. Hence, use of said method as claimed is not limited to the same X-ray view during the whole procedure.
