A three dimensional ultrasonic diagnostic imaging system is operated to guide or observe the operation of an invasive medical device () in three dimensions. An interventional system () is used to operate the invasive medical device () and produces spatially-based information relating to the activity of the invasive medical device (). The spatially-based information from the interventional system () is merged into the three dimensional ultrasonic image data to produce a live three dimensional image of the invasive medical device () or its activity. In one embodiment the locations where the activity of the invasive medical device () is performed is recorded and displayed in the three dimensional ultrasonic image. The three dimensional ultrasonic image may be shown as an anatomical volume rendered image or as a wire frame model () of the anatomy. In another embodiment an integrated three dimensional ultrasonic imaging and invasive device system is described.

Guidance of invasive medical devices by three dimensional ultrasonic imaging

A three dimensional ultrasonic diagnostic imaging system is operated to guide or observe the operation of an invasive medical device () in three dimensions. The invasive medical device () is shown in a detailed ultrasonic image and the balance of the volumetric region () in which the device is located is shown in a wide field of view. The detailed and wide fields of view may be displayed separately or overlapping in spatial alignment on an image display (). The wide field of view may be shown in two or three dimensions. A quantified display may be shown together with the wide and detailed anatomical displays. The detailed view may also be shown in an enlarged or zoomed format.

Guidance of invasive medical devices by wide view three dimensional ultrasonic imaging

A three dimensional ultrasonic diagnostic imaging system is operated to guide or observe the operation of an invasive medical device () in three dimensions. The appearance of the invasive device () in the three dimensional ultrasonic image is enhanced to be more readily observable by a clinician. The enhancement is produced by transmitting a greater ultrasonic beam density in a subvolumetric region including the invasive device () than in the surrounding portion of the volumetric region (). The beam density may be uniformly high in the subvolumetric region and uniformly low in the surrounding region, or may taper from a relatively high beam density around the invasive device () to a minimum beam density at distances removed from the invasive device ().

The present disclosure relates to a defibrillation/pacing electrode that comprises an electrode body, a conductor element, and an adhesive layer. When the electrode is in use, electrically conductive gel can be placed between the electrode and the patient's skin to form low impedance contact therebetween. In one embodiment, the electrically conductive gel is contained within a reservoir provided on the body, wherein the electrically conductive gel can be delivered from the reservoir to a patient's skin. In another embodiment, the electrically conductive gel is delivered to the skin through a valve mounted on the top surface of the body. In a further embodiment, the electrically conductive gel is supplied by a plurality of rupturable capsules that are impregnated within the adhesive layer.
