摘要:
Systems and methods for the assessment of fluid content and electrolyte balance in patients are provided. The systems generally include two or more ultrasound transducers and may include impedance-sensing electrodes as well. These elements are positioned about a soft tissue of a patient by means of a retention element.
摘要:
A dual-mode ultrasound system provides real-time imaging and therapy delivery using the same transducer elements of a transducer array. The system may use a multi¬ channel driver to drive the elements of the array. The system uses a real-time monitoring and feedback image control of the therapy based on imaging data acquired using the dual- mode ultrasound array (DMUA) of transducer elements. Further, for example, multi¬ modal coded excitation may be used in both imaging and therapy modes. Still further, for example, adaptive, real-time refocusing for improved imaging and therapy can be achieved using, for example, array directivity vectors obtained from DMUA pulse-echo data.
摘要:
Systems and methods for performing transcatheter coronary artery bypass grafting procedures are provided. The methods generally involve passing the graft from the aorta to the coronary artery through the pericardial space. The systems include poke-out wires, a coring device, and devices for forming anastomoses at the proximal and distal ends of a vascular graft.
摘要:
A system for diaphragmatic pacing includes an ultrasonic transducer and a control module. The ultrasonic transducer has an emitting surface. The emitting surface is configured to couple with a tissue of a patient. The transducer is configured to transdermally emit ultrasonic energy and induce movement in a thoracic diaphragm of the patient in response thereto. The control module is coupled to the transducer and has a processor. The processor is configured to execute an algorithm to control operation of the transducer.
