20120065498 | APPARATUS AND METHOD FOR MINIMALLY INVASIVE THERAPY OF MITRAL REGURGITATION - A system and method of treatment of mitral valve insufficiency using an implantable medical device is described. The system uses a C-arm X-ray device configured to produce computed-tomographic (CT)-like images, and to superimpose the CT-like images on a fluoroscopic image taken with the same X-ray device as a part of the treatment procedure. The fluoroscopic images are used to guide a catheter in the patient so as to place the medical device in a proper position. The efficacy of the procedure may be assessed using a non-invasive or minimally invasive acoustic imaging technique. | 03-15-2012 |
20130197354 | MINIMALLY INVASIVE TREATMENT OF MITRAL REGURGITATION - A method of guiding a catheter during a treatment procedure includes acquiring scan data of a patient volume in position for the treatment procedure, registering volume data of the patient volume to the scan data, acquiring fluoroscopic data for the patient volume during the treatment procedure, and generating a volume representation of the fluoroscopic data during the treatment procedure. Generating the volume representation includes superimposing the fluoroscopic data on the volume data based on the registering. The volume representation of the fluoroscopic data is displayed, the volume representation showing a position of a mitral valve clip carried by the catheter relative to the patient volume. | 08-01-2013 |
