|20140316234||APPARATUS AND METHODS FOR ACCURATE SURFACE MATCHING OF ANATOMY USING A PREDEFINED REGISTRATION PATH - A method includes scanning a bodily tissue of a patient with an imaging device and prior to an interventional procedure to produce an image of a surface of an organ. At least a portion of a registration path associated with the organ is defined. The method further includes surgically exposing the organ and placing a probing instrument in contact with the organ at a starting point associated with the registration path and moving the probing instrument substantially along the registration path to define a registration surface of the organ. The method further includes mapping the registration surface of the organ to the image of the surface of the organ based at least in part on the registration path.||10-23-2014|
|20140078138||APPARATUS AND METHODS FOR LOCALIZATION AND RELATIVE POSITIONING OF A SURGICAL INSTRUMENT - Systems, apparatus and methods for localizing and/or determining the relative position of surgical instruments during a surgical procedure are disclosed. A method includes capturing an image depicting at least a portion of a first surgical instrument disposed at a first position with respect to a target tissue, and at least a portion of a second surgical instrument disposed at a second position with respect to the target tissue, the second position different from the first position. The method includes transforming the image to a three-dimensional model so the first position of the portion of the first surgical instrument is rendered with the three-dimensional model, and the second position of the portion of the second surgical instrument is rendered with the three-dimensional model. The method includes calculating distance between the portion of the first surgical instrument and the portion of the second surgical instrument based on the three dimensional model.||03-20-2014|
|20130178745||ULTRASOUND TRACKING ADAPTER - An ultrasound tracking adapter assembly that attaches to an ultrasound transducer in a repeatable, rigid, and tool-less manner. When used with a tracked body, the position of the tracking technology devices and the ultrasound transducer is fixed, so intraoperative calibration is not necessary. This permits a 3D guidance system and 2D ultrasound to be used together. The adapter provides a secure, rigid hold between the ultrasound transducer body and the clamping body. The ultrasound probe clamp assembly is attached to specific probe instruments used in the operating room that are to be tracked using 3D positioning technology.||07-11-2013|
|20130079770||IRE GUIDANCE COLLAR - An IRE guidance collar assembly used to support an IRE needle or other ablation-type devices, comprising a guidance collar eye component and a guidance collar tube component. The collar eye component is movable, and slides freely along the guidance collar tube. This provide rigidity to the IRE needle while allowing various depths of insertion. The IRE needle body is seated in the receiving end of the guidance collar tube, with the needle inserted into and through the tube end of the guidance collar tube. One end of the guidance collar eye component snaps onto and fits over the tube end of the guidance collar tube, while the other end has a needle holder through which the IRE needle is inserted. The collar eye end slides along the tube end of the guidance collar tube, moving the needle holder of the collar end close to or away from the end of the guidance collar tube, as desired.||03-28-2013|
