Abstract: A control handle for a steerable catheter. A housing with a hollow interior region has a rotatable lever mechanism. Features are formed in the housing and on the lever mechanism for routing and affixing the catheter guidewire and to provide tension on the guidewire in a push/pull operation.

Abstract: A steerable catheter. A catheter tube is connected to a catheter handle. A steering wire has a center point affixed to the distal tip of the catheter tube, and each leg of the steering wire is affixed to respective racks inside the catheter handle. The racks are toothed and slidable and are mounted in opposition to each other within the catheter handle. A gear is disposed between the toothed racks and a knob is attached to the gear. Operating the knob rotates the gear and causes the racks to slide in opposite directions thereby pulling one of the steering wire legs to deflect the distal end of the catheter tube.

Abstract: A Wireless Catheter Module (WCM) is adapted for attachment to a diagnostic catheter to enable the bio-electrical signals, analog signals picked up by the probing electrodes imbedded in the attached catheter, to be captured and digitized by A-to-D converter electronics in the WCM whereupon packets of the digitized signals can then be transmitted wirelessly from the WCM to a remote Wireless Base Station (WBS) forming a receiver component of the present system. The WBS is adapted for operative connected to an EP recording and cardiac stimulation system. In cases where multiple catheters are to be used in a study, each catheter may be fitted with an appropriately configured WCM and the catheter modules can communicate simultaneously with the WBS.

Abstract: A movable and radiologically protective enclosure for a physician or medical technician working in close proximity to a source of radiologic energy. The embodiments include a lower assembly for enclosing and radiologically shielding the lower torso and legs of the user, and for supporting an upper assembly designed to enclose and radiologically shield the upper torso and arms of the user. A transparent radiologically impervious dome or the like is carried by the upper assembly to receive and protect the head of the user as well as allow visual and functional access to patients and/or radiologic equipment Means are provided for allowing the upper assembly to be vertically adjusted in position and to angularly tilt the torso and/or head protecting components. Protective sleeves are also provided at frontal ports for allowing the user to protectedly reach into the work area.
