摘要： A circulation assist system measures impeller displacement for use in estimating a blood flow rate related parameter. A circulation assist system includes a blood pump and a controller. The blood pump includes an impeller magnetically supported within a blood flow channel. The blood pump includes one or more sensors configured to generate output indicative of displacement of the impeller along the blood flow channel induced by a blood-flow induced thrust load applied to the impeller. The controller is configured to process the output generated by the one or more sensors to determine the displacement of the impeller along the blood flow channel. The controller is configured to process the determined displacement of the impeller to estimate at least one of the thrust load applied to the impeller, a pressure differential of the blood impelled through the blood flow channel, and a flow rate of blood pumped by the blood pump.

摘要： The systems, devices, and methods presented herein use a blood pump to obtain measurements of cardiac function. The system can quantify the functioning of the native heart by measuring certain parameters/signals such as aortic pressure or motor current, then calculate and display one or more cardiac parameters and heart function parameters, such as left ventricular pressure, left ventricular end diastolic pressure, or cardiac power output. These parameters provide valuable information to a user regarding current cardiac function, as well as positioning and function of the blood pump. In some embodiments, the system can act as a diagnostic and therapeutic tool. Providing cardiac parameters in real-time, along with warnings about adverse effects and recommendations to support cardiac function, such as increasing or decreasing the volumetric flow rate of blood pumped by the device, administering pharmaceutical therapies, and/or repositioning the blood pump allow clinicians to better support and treat cardiovascular disease.

摘要： A system allows for collection and re-use of a fluid medium derived from diverting at least some of the fluid medium of an injection. The system comprises a sterile container, an injector, a delivery catheter, a flow diverter assembly and a diversion reservoir assembly. The delivery catheter is in communication with a selected site within a patient's body. The flow diverter assembly is disposed in a flow path between the injector and the delivery catheter and is configured to divert at least a portion of a medium of the injection from the flow path. The diversion reservoir assembly has a reservoir chamber fluidly coupled to the flow diverter assembly The reservoir chamber is configured to receive the diverted portion of the fluid medium to allow re-use by the medium injector of the diverted portion.

摘要： One aspect of an intravascular ventricular assist device is an implantable blood pump where the pump includes a housing defining a bore having an axis, one or more rotors disposed within the bore, each rotor including a plurality of magnetic poles, and one or more stators surrounding the bore for providing a magnetic field within the bore to induce rotation of each of the one or more rotors. Another aspect of the invention includes methods of providing cardiac assistance to a mammalian subject as, for example, a human. Further aspects of the invention include rotor bodies having helical channels formed longitudinally along the length of the body of the rotor where each helical channel is formed between peripheral support surface areas facing radially outwardly and extending generally in circumferential directions around the rotational axis of the rotor.

摘要： A guidewire system may include a guidewire having a relatively stiff proximal section and a relatively flexible distal section joined by a transition region, and a TAVI device slidably disposed on the guidewire. The guidewire may include an expandable element disposed about the transition region. The expandable element may be configured to expand from a collapsed configuration to an expanded configuration. The guidewire may include an expandable element disposed at the distal end. The distal section may be pre-configured to form more than one distal loop. A method of protecting an apex of a left ventricle during a TAVI procedure may include inserting a guidewire into the left ventricle, positioning a transition region adjacent the apex, expanding an expandable element such that the expandable element spans the apex, advancing a TAVI device distally over the guidewire to an aortic valve, and performing a TAVI procedure at the aortic valve.

摘要： In the treatment method, a surgeon introduces a catheter assembly into a blood vessel in an arm, and delivers a distal portion of the catheter assembly to a predetermined position of a lower limb through the blood vessel in the body. Moreover, in the treatment method, the surgeon pulls an inner catheter out of an outer catheter, causes a treatment device to advance to the treatment target through the inside of the outer catheter, and treats the treatment target by the treatment device.
