摘要： Disclosed is a device for providing resuscitation or suspended state through redistribution of cardiac output to increase supply to the brain and heart for a patient, the device comprising an electrically controllable redistribution component in the form of a catheter, which is attachable to the patient and being configured to interact with the patient to provide redistribution of the cardiac output to increase supply to the brain and heart, the redistribution component following a predefined reaction pattern based on an electrical signal, and computer means configured to: receive a patient data which identifies physiological and/or anatomical characteristics of the patient; and provide the electrical signal for the redistribution component based on the patient data or a standard response. The device also comprises means for detection of blood vessels and motorized means for introduction of the catheter into an artery.
The device may provide mechanisms to protect the aorta and the remaining anatomy of the patient from inadvertent damage caused by the disclosed device in any usage scenario of either correct intended usage or unintended usage.

摘要： An embodiment of a uterine hemorrhage controlling system comprises a suction module including a suction end coupleable to a pump by a connecting tube, and a sealing module coupled to the suction module. The system may further comprise the pump and a filter coupled to the suction module. A uterine hemorrhage controlling method comprises: shielding a suction module that has been delivered into a uterus; sealing an entrance into the uterus while the suction module is situated within the uterus; applying a negative pressure within the uterus upon activation of a pump; and maintaining the negative pressure within the uterus to induce uterine contraction. The method may further comprise delivering the suction module into the uterus; transmitting bodily fluids, out of the uterus through the suction module, and filtering the bodily fluids.

摘要： An improved catheter device for selectively isolating and occluding a portion of the descending aorta and/or the iliac vasculature of a patient, including a guiding or isolating component on a distal end of an elongate hollow catheter shaft which is advanceable though the vascular system of the patient. The catheter shaft has a proximal portion that extends out from the patient and a distal portion adapted to be disposed within the vasculature of the patient. The guiding or isolating component as well as a plurality of expandable members are disposed on the distal portion. A number of expandable members are positioned on the catheter with dimensions and configured so that when expanded it rests within a target artery or vasculature to occlude blood flow. Other expandable members may be spaced apart from the isolating or fixation member and configured to selectively isolate and occlude blood flow through different portions of target arteries and other vasculature.

摘要： Systems and methods are provided for treating conditions such as heart failure and/or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The system may include sensors to determine the degree of occlusion of the superior vena cava. The occlusion system may be used to reduce volume in a heart and facilitate a cardiac procedure. The occlusion system may be used to relieve an overloaded chamber during and/or after deploying a VAD.

摘要： A therapeutic agent delivery system includes a catheter, a vascular occluder, a pressure sensor system, and a pump system. The vascular occluder is provided at a distal end of the catheter. The pressure sensor system is provided to sense pressure at a distal end of a catheter lumen, and provides feedback to the pump system. The pump system is adapted to control a rate of infusion of a therapeutic agent through the catheter lumen based on the pressure sensed by the pressure sensor system. A method includes deploying the vascular occluder in a vessel, and then sensing a pressure in the vessel. The therapeutic agent is infused into the vessel at a flow rate based on the sensed pressure in the vessel.

摘要： A temporary esophagus occlusion device for providing temporary occlusion of the esophagus during intubation of a in patient includes a frame configured to transition between a contracted state, in which it can be swallowed by the patient, and an expanded state, wherein in the expanded state, the frame has a maximum outer diameter sufficient to span an inner diameter of the esophagus of the patient. The device also includes a flexible cover connected to and extending over at least a portion of the frame when the frame is in the expanded state to at least partially block flow of fluid and/or solid materials through the esophagus and a guidewire attached to the frame, sized to be swallowed by the patient along with the frame and having a proximal end portion configured to remain external to the patient's body and a distal end connected to the frame.
