    摘要: A steerable catheter system to perform a transseptal puncture procedure comprises a steerable catheter shaft with at least one inner lumen, and an inner element slidably positioned within a shaft lumen, wherein the distal tip of the shaft can be deflected, counter-deflected, rotated, and counter-rotated and wherein the inner element can be deployed or retracted. In one embodiment, a single steerable catheter is capable of performing an intended procedure and a transseptal procedure all in one, wherein the catheter comprises an outer steerable catheter and an inner element which can be deployed to perform a transseptal puncture, and wherein, once the inner element crosses the inter-atrial septum, the catheter itself can slide forward without advancement of the inner element.

    摘要: A transesophageal defibrillating system includes a large area anterior patch electrode and a large area posterior patch electrode, as in some conventional exterior defibrillating systems. An esophageal probe has a pair of ring electrodes, one of which is carried at or near its distal end. The system is operatively arranged to supply defibrillation pulses between the large anterior patch electrode and either the distal electrode (carried by the probe) or the large posterior electrode, depending on which one of the latter two electrodes is connected or coupled by the clinician or paramedic to the defibrillating pulse source. The system includes a source of pacing pulses which may be supplied to the patient via the anterior patch electrode and at least one of the electrodes carried by the esophageal probe. The distal electrode is believed to be the more effective electrode to use for this purpose. The system also preferably provides for sensing, displaying and recording ECG signals, the two electrodes carried by the probe supplying input representing electrical activity of the heart for display and/or recording.

    摘要: A system for and method of treating a malfunctioning heart is based on hemodynamics, the O.sub.2 in blood at a site in a patient's circulatory system being sensed. A signal is developed representative of short term O.sub.2 level in the blood preferably at a site which carries mixed venous blood. A signal representative of a baseline O.sub.2 level (fixed or varying) is provided and if the short term current O.sub.2 level differs therefrom by a predetermined value, an indication of possible hemodynamic compromise. The heart rate is sensed and signals develop indicative of which of a number of rate ranges into the current rate falls. One or another or more than one of a plurality or heart malfunction corrective inputs to the patient are delivered, as needed. The system may include a failsafe antibradycardia pacemaker, if desired.

    摘要: A remotely controlled insertion system for a medical device is described. The system comprises a robotic device and a remote control mechanism. The robotic device has a handle controller to receive and hold the control handle or proximal end of a medical device. The medical device is capable of moving in up to six ranges of motion. In one embodiment a first motor is connected through a drive screw to a handle controller to move the medical device forward and backward. A second motor is connected to drive wheels effective to rotate the medical device clockwise and counter-clockwise. A third motor drives a series of gears that are connected to one or more control members on the medical device, this being effective to deflect a tip of the medical device so that movement of the third motor causes such deflection. A control unit is connected to all three motors.

    摘要: A system for and method of treating a malfunctioning heart is based on hemodynamics, the pressure at a site in a patient's circulatory system being sensed. A signal is developed representative of short term mean arterial pressure (MAP), mean right atrial pressure (MRAP), mean right ventricle pressure (MRVP), mean left atrial pressure (MLAP), mean left ventricle pressure (MLVP), mean central venous pressure (MCVP), mean pulmonary artery pressure (MPAP), mean pulmonary vein pressure (MPVP), mean pulmonary capillary wedge pressure (MPCWP), right ventricular systolic pressure (RVSP), right ventricular end diastolic pressure (RVEDP), or right ventricular pulse presure (RVPP). A signal representative of fixed or varying baseline pressure is provided and if the short term current pressure differs therefrom by a predetermined value, an indication of hemodynamic compromise, cardioversion/defibrillation is effected. In a second embodiment, the determination of whether the difference between fixed or varying baseline pressure and current pressure is undertaken after a rate criteria (for example a heart rate above 155 b.p.m.) has been met. In a third embodiment, the rate and pressure criteria both must exist at the same time, before cardioverting/-defibrillation is initiated. In a fourth embodiment, a microprocessor is used. The system may be integrated with antitachycardia and/or antibradycardia pacemakers.

    摘要: A system for and method of treating a malfunctioning heart is based on hemodynamics. The mean arterial pressure (MAP) mean right atrial pressure (MRAP), mean right ventrical pressure (MRVP), mean left atrial pressure (MLAP), mean left ventrical pressure (MLVP) or mean central venous pressure (MCVP) is sensed. The long term mean baseline pressure is monitored and if the short term current mean pressure differs therefrom by a predetermined value, an indication of hemodynamic compromise, cardioversion/defibrillation is effected. In a second embodiment, the determination of whether the difference between mean baseline and mean current pressure is undertaken after a rate criteria (for example a heart rate above 155 b.p.m. has been met. In a third embodiment, the rate and pressure criteria both must exist at the same time, before cardioverting/defibrillation is initiated. In a fourth embodiment, a microprocessor is used.

    摘要: A catheter management system comprises several layers where a top layer has one or more channels to receive one or more elongated medical devices or members and a bottom layer comprises adhesive to secure the catheter management system to a patient or other secure site in the operating field. A firm upper surface causes the elongated medical devices or members to stay in the channels, whereas a firm inner layer facilitates maintaining the shape of the catheter management system and providing resistance for an operator to easily release an elongated medical device or member.

    摘要: A method and system improves the effectiveness of cardioversion or defibrillation through the ability to switch shock vectors and to reduce transthoracic impedance. An external multiple patch system comprises at least two options for a shocking vector once external patches are applied and adhered to desired locations on a patient's body. A manual switching mechanism in the system provides the ability to direct current from a defibrillator to either of two or more adhesive electrode patches. A method and system of decreasing transthoracic impedance comprises wrapping material around a patient's body to apply pressure to adhered patches, which further reduces transthoracic impedance by increasing effective pressure on the patches through use of pressure-focusing mechanisms located between a patch and a strap.
