Abstract: System and method for tracking and control in medical procedures. The system including a device that deploys fluorescent material on at least one of an organ under surgery and a surgical tool, a visual light source, a fluorescent light source corresponding to an excitation wavelength of the fluorescent material, an image acquisition and control element that controls the visual light source and the fluorescent light source, and captures and digitizes at least one of resulting visual images and fluorescent images, and an image-based tracking module that applies image processing to the visual and fluorescent images, the image processing detecting fluorescent markers on at least one of the organ and the surgical tool.

Abstract: Apparatuses and methods for performing anastomosis of distal and proximal vessels. An exemplary apparatus includes a distal anastomosis includes a distal hub and a distal engagement segment. The distal hub is configured to detachably connect to a distal catheter. The distal engagement segment is connected to the distal hub and includes one or more distal arm segments that are configured to engage an inner wall of the distal vessel.

Abstract: A device, system, and method for entering a medical device such as a needle into the body inside a medical imager such as a MRI scanner, CT, X-ray fluoroscopy, and ultrasound imaging, from within a body cavity (such as the rectum, vagina, or laparoscopically accessed cavity). A three degree-of-freedom mechanical device translates and rotates inside the cavity and enters a needle into the body, and steers the needle to a target point selected by the user. The device is guided by real-time images from the medical imager. Networked computers process the medical images and enable the clinician to control the motion of the mechanical device that is operated within the imager, outside of the imager or remotely from outside the imager.

Abstract: Featured are a device for compression of target tissue while magnetic resonance imaging the target tissue and methods and systems related thereto. The method includes disposing target tissue between the fixed surface and the moveable member of a compression device and compressing the target tissue between the fixed surface and the moveable member. The method also includes acquiring one or more, more specifically a plurality, of sequences of image data of the compressed target tissue using an MRI imaging technique (MRI). In embodiments, the MRI technique is a SENC MRI technique, where tissue encoding is done prior to compressing the tissue and acquiring includes adding a gradient moment in the slice-selection direction to cause demodulation with a specific frequency, hi further embodiments, the sequences of image data are acquired during a single compression and prior to recovery of magnetization.

Abstract: The end-effector (150) includes a sheath (152) and a medical device or needle carrier (154) that is disposed within the interior compartment (160) of the sheath. Aperture (162) is located in a portion of the sheath proximal a distal end of the sheath that is inserted into a natural or artificial cavity. This device is guided by a real-time imager.

Abstract: A magnetic resonance imaging (MRI) probe apparatus is described. The MRI imaging probe includes a coil section having an imaging coil, and a handle section connected to the coil section. The handle section having a phase shifter circuit with inductors, capacitors, and coax line electrically connected and configured to provide appropriate phase shift. The handle section further having a coaxial cable winding electrically connected to the imaging coil, and wound cylindrically, and having a slot therethrough between the ends of the cylindrical winding. The handle section further having a pre-amp circuit mounted on a substrate and electrically connected to the cylindrical coax winding.

Abstract: An intervention apparatus is described having a probe with an orifice insertion portion, the insertion portion being configured for insertion into an orifice of a patient. The apparatus also having an intervention tool securement and adjustment mechanism removably attached to the probe. The probe providing support to hold the mechanism in a position relative to the patient, and the adjustment mechanism providing adjustment of an entry point and an angle of entry for an intervention tool to the patient. In embodiments, magnetic resonance imaging, trans-orifice intervention and transperineal intervention are described. Methods for imaging and/or intervention are also described.
