Abstract: A computer may be remotely accessed. At a first location, display commands are generated. The display commands are covered into a compressed video data stream. Each display element (5) is checked if it is encoded (52). If object is encoded, it is transcribed into MPEG (54). The image is adjusted for display (56) and compression (58). Additional steps of motion determination (60), change detection (62), compression depth and frame determination (66, 68) are executed. Then the data is transmitted to a second location. The display commands are decompressed and displayed as an image at the second location.

Abstract: A method for treating tissue comprising the steps of providing a probe including a body having a distal tip, a position sensor for determining a position of the distal tip and a hollow needle movable from the distal tip of the body. The probe is brought into contact with a tissue portion and the hollow needle is moved out of the distal tip of the body and into the tissue portion whereby a therapeutic agent is injected into the tissue portion through the hollow needle.

Abstract: The invention comprises methods of increasing contractile force and/or the motility of a GI tract. A first method comprises selecting a portion of the GI tract and applying a non-excitatory electric field to the portion, which field increases the force of contraction at the portion. A second method comprises determining a timing of a returning wave in the GI tract and applying an electric field to at least a portion of the GI tract, which electric field reduces the response of the GI tract to the returning wave.

Abstract: A method of promoting the healing of a lesion in a smooth muscle, comprising selecting a smooth muscle portion having a lesion and applying a non-excitatory electrical field to the portion, which field reduces the mechanical activity of the portion.

Abstract: An apparatus for blocking the electric activity of an area of tissue, comprises circuitry (S) for creating a long non-excitatory electric signal between at least two points (R1, R2) located in the vicinity of a muscle

Abstract: This invention is an apparatus for heart packing with cardiac output modification, including one or more electrodes (27, 29) which apply electrical signals to muscle. Signal generation circuitry (26) applies an excitatory electrical pulse to at least one of the one or more electrodes to pace the heart and a non-excitatory stimulation pulse to at least one of the one or more electrode s to modify the cardiac output. Preferably the circuitry synchronizes the non-excitatory stimulation pulse with the pacing pulse.

Abstract: A medical probe such as a catheter (20) is guided within the body of a patient by determining the relative positions of the probe relative to another probe, as by transmitting non-ionizing radiation to or from field transducers (30, 230) mounted on both probes. In one embodiment, a site probe (28) is secured to a lesion within the body, and an instrument probe (200) for treating the lesion may be guided to the lesion by monitoring relative positions of the probes. Two or more probes may be coordinated with one another to perform a medical procedure.

Abstract: A method of excavating tissue in the body, including bringing a catheter (60) to a location, injecting microbubbles (84) at the location and causing cavitation of tissue (76) at the location using ultrasound. Preferably, the microbubbles (84) are injected directly into the tissue, such as by using a hollow needle (62). Alternatively, microbubbles (84) are injected into the vascular bed of the tissue at the location, so that the capillaries (86) are infused with microbubbles (84).
