    摘要： Methods and apparatuses for the image guidance and documentation of medical procedures. One embodiment includes combining small field of view images into a recorded image of with a large field of view and aligning the small field of view real time image with the recorded image through correlation of imaging data. A location and orientation determination system may be used to track the imaging system and provide a starting set of image alignment parameters and/or provide change updates to a set of image alignment parameters, which is then further improved through correlating imaging data. The recorded image may be selected according to real time measurement of a cardiac parameter during an image guided cardiac procedure. Image manipulations planned based on the recorded image can be stored and applied to the real time information. The position of the medical device may be determined and recorded through manipulating a cursor in a 3-D image space shown in two non-parallel views.

    摘要： An echogenic medical device, such as a needle catheter, which produces an improved ultrasonic image of the device, and a method of performing a medical procedure using a device of the invention. One aspect is directed to a catheter which reduces artifacts in the ultrasound image of the catheter. In one embodiment, the catheter has a spherical distal tip. Another aspect of the invention is directed to an echogenic catheter with echogenic portions arranged in an array to facilitate determination by ultrasonic imaging of the rotational orientation of the catheter relative to a desired location within the patient.

    摘要： A guiding catheter system employs a flexible shaft having a preformed bend at a distal end. An ultrasound transducer is mounted proximal to the pre-formed bend. The ultrasound transducer has a field of view directed to a distal tip of the guiding catheter. The guiding catheter includes an open lumen adapted for the introduction of payloads through the catheter system. The guiding catheter system can be used to direct a smaller guiding catheter or guide wire into a destination vessel from a heart chamber. In one application, the guiding catheter system is used to introduce a guiding catheter into the coronary sinus ostium from the right atrium.

    摘要： The invention relates to an apparatus and method for imaging and mapping various structures located at a target area within a patient's lumen using conventional IVUS technology. The mapped images are used to accurately determine and control the location of the device within the lumen relative to the target area and/or target site. Once the drug delivery device is properly positioned within the lumen, additional ultrasonic images are generated and used to control the position and depth of penetration of a retractable needle of the device. Needle position can be precisely determined, both in relationship to the device as well as the target site for drug delivery. This allows accurate delivery of drug to the target site and, thus, enhanced treatment capabilities.
