    Abstract: Devices and methods for ultrasound image-guided percutaneous, cardiac valve implantation and repair comprise, in combination, a plurality of devices including but not limited to an ultrasound-image guided catheter, a pericardial sheath, a cardiac-valve delivery system and an ascending aortic filter. An image-guided catheter is utilized to introduce via an introducer needle and a guide wire a pericardium portal for permitting entry from the chest wall to inside the pericardial space between the pericardial outer lining and inner lining. The pericardium portal permits the use of ultrasound vision to locate a site proximate the left ventricular apex, for introduction of a sheath via a .myocardium needle into the left ventricular space at an angle and avoiding any coronaries or vessels. A first delivery system permits placement of at least one aortic filter which collects any emboli, particulate matter, plaque and prevents such matter travelling via the ascending aorta to the brain, causing a stroke.

  • Patent number: 11419660
    Abstract: This invention pertains a system and methods for ablation treatment of tissues. The invention aims to aid healthcare professionals in completely treating all the target tissues by fusing computer generated information highlighting which tissues have been treated and which not to images of the tissues. The systems and methods integrate seamlessly with current image-guided procedures and do not require tracking systems to gather the position of the ablation device, as the positon and orientation of the device are identified from images. The invention aims also to improve estimates of the ablation volumes associated to an ablation device by identifying from images the true geometry of devices that might deform during the deployment in tissues; the invention aims to improve estimates of the ablation volumes by using information about the ablation process and about the status of tissues which can be collected from the control system of the ablation device.
