Respiratory support and / or controlled mechanical ventilation of a patient are provided. A ventilation apparatus may include a ventilator, a transtracheal prosthesis, and a respiratory relief device. The transtracheal prostheses and ventilation catheter may be arranged such that the patient can breathe freely through the upper airway and / or the tracheal prostheses. Respiratory sensors may measure a breathing rate, lung pressure, airway pressure, or a combination thereof. Pulses of gas may be provided to the patient through the ventilation catheter during inspiration. The pulses may have a first volume while the patient breathes normal and a second volume when the sensors detect a cessation of breathing or reduction in breathing volume. The second volume may be provided at 1-5 times the normal breathing rate, with a volume 25-500% times the first volume, or both.

Tracheal catheter and prosthesis and method of respiratory support of a patient
ActiveUS20050034721A1Improve the quality of lifeEfficient methodTracheal tubesOperating means/releasing devices for valvesAutonomous breathingOxygen
The invention is relative to a method and an apparatus for supporting the respiration of a patient and to a tracheal prosthesis. According to the invention the spontaneous respiration of a patient is detected by sensors and at the end of an inhalation procedure an additional amount of oxygen is administered to the lungs via a jet gas current. This improves the absorption of oxygen during inhalation. If required, the exhalation procedure of the patient can be arrested or slowed by a countercurrent in order to avoid a collapse of the respiration paths in this manner. This procedure is realized by an apparatus comprising an oxygen pump that can be connected to an oxygen source and comprising a tracheal prosthesis that can be connected via a catheter. The spontaneous respiration of the patient is detected by sensors connected to a control unit for activating the oxygen pump. The tracheal prosthesis comprises a tubular support body with a connection for the catheter and two of the sensors are associated with the support body. The tracheal prosthesis and the jet catheter that is integrated or can be introduced are dimensioned so that the patient can freely breath and speak without restriction.

Multi-dimensional cardiac imaging
ActiveUS20120146641A1High scan accelerationImprove robustnessDiagnostic recording/measuringMeasurements using NMR imaging systemsMissing dataMedicine
A 5-dimensional imaging method and system is provided to acquire and display the effect of dynamic physiologic changes (either spontaneous or induced) on cardiac function of a patient's heart to elucidate their effects on diastolic myocardial function. In a patient free-breathing magnetic resonance imaging study, 3-dimensional spatial information is encoded by a non-Cartesian 3-dimensional k-space readout trajectory and acquired concurrently with recordings of cardiac and respiratory cycles. The advantage of using non-Cartesian sampling in this invention compared to, for example, Cartesian sampling is higher scan acceleration, improved robustness to motion / flow effects (incoherent instead of coherent artifacts) and robustness to missing data points in k-space.

A spinal-length mattress including a means for providing buoyancy to a human torso and abdomen thereon; attached to the mattress at one end, a pelvic support portion; and attached to the mattress at an opposite end, a head rotation stabilization portion having an air passage opening allowing a person to breathe freely when resting in a face down position thereon. By supporting the pelvis and stabilizing the head to substantially limit motions of the neck, a central cushion (preferably dominated by a “shape memory foam” filling) allows the spinal column to passively distribute all directional stresses—including those deriving from body mass and from muscle tension. Thus relieved of stress, disks between spinal bones begin to return to their respective naturally compliant symmetrical shapes; thereby generally providing a long term benefit in exchange for a quarter hour or a half hour of regular prone-oriented engagement with the mattress.

Magnetic resonance imaging of coronary venous structures
InactiveUS20080221429A1Improve blood-myocardium contrastSuppresses coronary vein signalMagnetic measurementsDiagnostic recording/measuringVenous blood specimenVenous blood
A method and system for magnetic resonance imaging comprises applying at least one radiofrequency magnetization transfer (MT) pulse to a coronary venous region of a subject positioned within a magnetic field, and acquiring magnetic resonance imaging data from the coronary venous region to produce an image of a coronary venous structure. This technique can be utilized as part of a 3D free-breathing, ECG-triggered gradient-echo Cartesian acquisition of the coronary region. One or more magnetization transfer (MT) preparation pulses are used to enhance the contrast between venous blood and myocardium. The MT preparation results in myocardial signal suppression without any significant signal loss in the arterial or venous blood so as to maintain venous blood signal-to-noise ratio while improving contrast between myocardium and veins. The coronary venous structure can comprise one or more of a coronary sinus, a lateral vein and a posterior vein. The image of a coronary venous structure can be acquired in connection with an interventional cardiovascular procedure, such as a cardiac resynchronization therapy.
