Title: Subcutaneous defibrillation electrodes
Inventor: DAHL ROGER W
IPC: A61N1/39
Filed: 1990-10-16
Granted: 1999-05-04
Abstract: Implantable electrodes for defibrillation are formed of pluralities of electrode segments.  Each of the segments is relatively long and narrow.  The electrode segments can be parallel and spaced apart from one another a distance at least ten times the nominal width, with one end of each segment mounted to a transverse distal portion of an electrically conductive lead coupling the electrode to a defibrillation pulse generator.          Alternatively, segments can branch or radiate outwardly from a common junction.  In yet another arrangement, electrode segments are portions of a single conductive path at the distal end of a lead from a pulse generator, arranged in either a spiral configuration or a serpentine configuration which can align electrode segments side by side, parallel and spaced apart.  The electrode segments can be formed of composite conductors in the form of titanium ribbons or wires with a sputtered outer layer of platinum, or a silver core in a stainless steel tube, with a platinum layer formed onto the tube.  The electrodes are highly compliant yet can provide large effective areas for defibrillation, enabling a transthoracic pulsing arrangement of two electrodes on opposite sides of the heart, implanted subcutaneously outside of the thoracic region.

Title: Telescoping guide catheter system
Inventor: SHOCKEY RICK L
IPC: A61B17/22
Filed: 1991-01-10
Granted: 1996-07-09
Abstract: The guide catheter system for use in the treatment of coronary artery disease includes a first single-lumen catheter of a relatively large internal diameter to pass a second guide catheter therethrough.   The first guide catheter comprises an elongated flexible tube having a stainless steel braid embedded in the wall  thereof  for  imparting  desired  torqueability characteristics to it.   The first guide catheter is intended to be inserted at an appropriate point in the vascular system and then advanced until its distal end reaches the coronary ostium.  The second guide catheter is  fabricated  by  extruding  a  plastic,  such  as polyurethane thermoplastic resin over a tubular Teflon? core and because it is to be used within the lumen of the first catheter,  it need not include a braided structure within its walls to prevent it from kinking. This allows the second catheter to be sufficiently slim to permit it to be advanced into a coronary artery while allowing fluids to be perfused between the outer wall of the second guide and the inner wall of the first  guide  catheter  while  still  providing  a sufficiently  large  inner lumen to pass  a working catheter, e.g., an angioplasty or atherectomy catheter. An atraumatic tip is attached to the distal end of the second guide catheter.

Title: Coupling part arrangement comprising pressure-reducing members
Inventor: EKMAN THURE
IPC: F16L37/23
Filed: 1991-01-16
Granted: 1996-08-27
Abstract: A coupling part constituting the male or female part in  a  quick  coupling  comprises  an  inner,  longitudinally displaceable unit positioned in an outer part of the coupling part, the inner unit being adapted in a deactivated position thereof to confine the media pressure in a first chamber arranged in the outer part of the coupling part and in an actuated position to open or keep open an access for media to a second chamber in the outer part.  Pressure-reducing members actuable upon coupling together of the male and female parts and allowing for the coupling even at high media pressures, and including a lead-off channel for media pressure and a shut-off element positioned in the channel, and actuable by the end face of the other coupling part through an actuation member.  The actuation member is sealed-off or positioned in the coupling part in order to prevent lead-off media from reaching the end face of the coupling part. The lead-off channel on both side of the shut-off element is connectable to the first and the second chambers and upon actuation of the pressure-reducing member,  the  first  and  second  chambers communicate through lateral connections in the inner unit the lead-off channel and the opened shut-off element whereby accompanying decompression of  the pressure  in  the  first chamber facilitates the longitudinal displacement of the inner unit, as a result of which it is possible to obtain leakage-free connection of the coupling parts in the presence of any media pressure.

Patent CA-2077017-C (CA)
Title: Synchronous digital signal to asynchronous digital signal desynchronizer
Inventor: MEDIAVILLA RICARDO
IPC: H04L7/00
Filed: 1992-08-27
Granted: 1998-07-14
Abstract: Improved jitter performance is realized in a desynchronizer for obtaining an asynchronous digital signal, e.g., a DS3 signal, from a received synchronous digital signal, e.g., a SONET STS-1 signal. The improved jitter performance results from the use of a unique dynamic bit leaking arrangement in conjunction with a digital phase locked loop and desynchronizing elastic store. An optimum bit leak interval is obtained by controllably leaking a greater number of shorter interval STS-1 bits than the number of received pointer adjustment bits.Additionally, the affect of random pointer adjustments and the superposition of randomly received pointer adjustments on a periodic sequence of received pointeradjustments is minimized by employing a "static" queue of pointer adjustment bits to be leaked. The queue is dynamically maintained at its "static" count so that there are always bits in the queue to be leaked at the desired optimum bit leak interval even in the presence of randomly received pointer adjustments.
