Title: Catheter for electrophysiological procedures
Inventor: CIMINO WILLIAM W
IPC: A61B5/296
Filed: 1994-03-10
Abstract: ABSTRACT        A catheter adapted to perform electrophysiological procedures comprises a body member, a manipulation handle attached to the proximal end of the body member for applying torque to the body member, the handle having a control knob adapted for control movements in a first plane and in a second plane simultaneously. A deflection control line is attached at its distal end to the distal portion of the catheter and its proximal end attached to the control device of the handle so that tension applied to the control line by sliding the control knob causes deflection of the distal portion of the catheter. A stiffening member is disposed within the body member of the catheter and is slidable, said stiffening member providing increased rigidity to the portion of the body member in which the stiffening member is located. Rotation of the control knob controls the positionof the stiffening member in the body member. In a further aspect, a stiffening member in accordance with one embodiment includes a tapered distal end section with a ball formed on the distal tip, the tapered section terminating at the ball. In accordance with another aspect, the torsional rigidity of the catheter body is increased by use of a layer of aramid fibers mixed with an epoxy. In yet anotherfeature, the handle and rotatable sliding element are symmetrically shaped to facilitate complete single-handed operation of the handle by the physician of all position control aspects of the catheter.

Title: Combustor bypass system for a gas turbine
Inventor: KAIN JEFFREY A
IPC: F02C9/16
Filed: 1994-12-21
Abstract: An apparatus for causing a portion of the compressed air from the compressor section of a gas turbine to bypass the combustor.  The apparatus comprises a clamping ring and a rotating ring.  The clamping ring joins the aft end of the combustor to the front end of a duct that directs the hot gas from the combustor to the turbine section.  The rotating ring encircles the clamping ring.  When the rotating ring is rotated  into  a  first  position,  ports  disposed  in  the rotating ring are aligned with ports in the clamping ring so that air can flow into the hot gas flowing between the combustor and the duct.  However, the ports in the rotating ring are completely blocked by the clamping ring when the rotating  ring  is  rotated  into  a  second  position  and partially blocked when the rotating ring is rotated into intermediate positions.  An actuating ring that encircles the combustion chamber controls the rotation of the rotating ring by means of an actuating rod that extends into the shell.

IPC: A61B5/296
Filed: 1994-01-28
Abstract: A method and system for treating a patient's heart exhibiting arrhythmia by first detecting electrical activity within the patient's heart to determine the location of the arrhythmogenic site or conductive pathway causing the arrhythmia and then creating an infarct within the region of the patient's heart where the arrhythmogenic site or the conductive pathway causing the arrhythmia is located by delivering an occluding element to a coronary artery which delivers oxygenated blood to said region of the patient's heart. In one presently preferred embodiment the occluding element is a flaccid or limp coil which when disposed in a coronary arterial passageway forms a randomly shaped, intertwined mass which quickly forms thrombus within the coronary artery to block the passage of oxygenated blood therethrough.
