  • Patent number: 7610104
    Abstract: The methods and apparatus for lead placement on a surface of the heart are employed using an elongated body having proximal and distal end portions. The body defines a lead receiving passageway extending between a proximal inlet and a distal outlet for receiving a lead therethrough for contact with the heart surface. The elongated body is adapted for insertion between a pericardium and an epicardial surface. At least a portion of the body may have a non-circular cross-sectional shape adapted to retain the body orientation between the pericardium and the epicardial surface.

  • Patent number: 7503474
    Abstract: A hydraulically actuated medical instrument includes an elongated shaft having proximal and distal ends, a hydraulically actuated end effector at the distal end of the shaft and a fluid flow path extending through the shaft to the end effector. The end effector may be directly manually operated by way of a handle located at the proximal end of the shaft or remotely, for example, via robotic controller. Articulation joints may be provided along the shaft, between the shaft and end effector or handle, or elsewhere. The hydraulic actuation of the present invention permits multiple axis instrument articulation, miniaturization and simplified instrument fabrication.

  • Patent number: 6755338
    Abstract: A hydraulically actuated medical instrument includes an elongated shaft having proximal and distal ends, a hydraulically actuated end effector at the distal end of the shaft and a fluid flow path extending through the shaft to the end effector. The shaft may be capable of an angled configuration where at least a portion of the shaft is manually movable to a direction in which it extends at an angle to another portion of the shaft. The end effector is not limited to a linear configuration and at least a portion of an elongated end effector extends at an angle relative to another portion of the end effector as is needed or desirable for the particular procedure to be performed.
